2 TECHNICAL DATA

2.1 Introduction This tabletop autoclave is designed for the sterilization of wrapped and

unwrapped instruments and related items found in dental, medical and veterinary clinics, first aid rooms, hospitals, laboratories, etc.

This autoclave is an electrically heated sterilizer using steam as the sterilizing agent. A computerized control unit ensuring a fully automatic sterilization cycle, control and monitoring of physical parameters and a clear documentation of the sterilization cycle controls the autoclave.

The autoclave has three automatic programs, according to the material to be sterilized, and one auxiliary drying program. Models EA and EKA are equipped with an air compressor that, during the drying stage, draws air through a HEPA filter (0.2µm). It pushes that air through the heated chamber to remove moisture and facilitate the drying operation. Drying is performed with the door closed.

On all models (except 1730), a water pump is installed between the water reservoir and the chamber. This pump guarantees fast and accurate filling of the chamber every time. Entry of water may be accompanied by a noise for approximately 30 seconds. This is normal noise generated by regular operation of the pump.

The control system provides adequate protection to ensure the safety of personnel and reliable operation with a minimum of shutdown time.

On all models (except 1730), a printer is an optional addition to the autoclave. The printer prints the preset and actual parameters of the cycle (temperature, time and pressure).

This manual is intended for the user and gives the user a general understanding of the instrument and the best ways to operate and take care of it in order to obtain optimum effective results.

After reading this manual, operating the autoclave will be easy. However, since this instrument is built with high technology sensitive components, no attempt should be made by the user or any other unauthorized person to repair or recalibrate it.

Only technical personnel, having proper qualifications and holding technical documentation (including a technician manual) and adequate information are authorized to service the apparatus.

2.2 Standby Heating Mode The autoclave provides an option of heating the chamber in standby

mode between cycles with a very low power in order to reduce total cycle time (1.6% of the total power only). The autoclave turns off automatically if the interval between the sterilization cycles is more than 2 hours. This feature is standard on all EK, EKA models and optional on all E, EA models.

2.3 Environmental Emission Information

1. The peak sound level generated by the autoclave is less than 70 dBA with background noise of 60 dBA.

2. The total heat per hour transmitted by the autoclave is < 100 Wh for all models.

3.2 Description and Functions of the Control Panel Keyboard 3.2.1 Program keys

(1) Unwrapped Instruments (2) Wrapped Instruments (3) Glassware (slow exhaust, no drying) Pressing one of the above program keys determines the chosen

program. The program parameters are displayed and the program indicator lights.

(4) Dry Only Pressing this key allows inclusion of the Additional Drying

procedure for a period of time determined by the operator. Time range is 0-99 minutes.

3.2.2 Other keys (5) TEMP.

Pressing this key places the marker under the temperature displayed on the display. To raise or lower the program sterilization temperature, press UP or DN keys. To store the new value in the memory, as the nominal setting, complete the changing of the parameter by pressing TEMP. key again. The permitted temperature range for proper sterilization is 250ºF-274ºF (121ºC-134ºC).

Note: In no case should the temperature be set higher than 274ºF

(134ºC) (6) STE. TIME

Pressing this key places the marker under the sterilization time displayed on the display. To raise or lower the program sterilization time, press the UP or DN keys. To store the new value in the memory, as the nominal setting, complete the changing of the parameter by pressing STE. TIME key again. Time range is 3-99 minutes.

Note: It is important to properly coordinate the STE. TIME

with the sterilization temperature.

(7) DRY TIME Pressing this key places the marker under the drying time

displayed on the display. To raise or lower the program drying time, press the UP or DN keys. To store the new value in the memory, as the nominal setting, complete the changing of the parameter by pressing DRY TIME key again. The time range is 0-99 minutes. This key does not allow any change of the dry time for the glassware program, for which it is permanently set to 00 minutes.

(8) UP Pressing this key in combination with TEMP. (5), STE TIME

(6), DRY Time (7) and CLOCK (9) increases these values.

19

(9) DN Pressing these keys in combination with TEMP. (5), STE

TIME (6), DRY Time (7) and CLOCK (9) lowers these values.

(10) CLOCK Pressing the CLOCK programming key displays the date, with

the cursor under the day. Pressing the UP or DN keys changes the date. Pressing the CLOCK key again moves the cursor to the month, then year and then time (hour, minute, second). At this point the display shows the currently set date and time. If no key is pressed during a 10-second interval, the system exits the clock-programming mode and returns to the current program display.

(11) Water Inlet Pressing this key continuously, allows for manual filling of the

chamber with water. Once the key is released the water pump stops, the fill valve closes and water stops entering the chamber.

(12) START Pressing this key starts the sterilization (or DRY ONLY)

process according to the selected program. Water flows automatically into the chamber, HEAT and STE. stages commence and the respective LED indicator lights up.

On completion of the sterilization program the Exhaust stage will automatically begin, at the end of which a Drying stage (if previously programmed) will initiate. The respective LED indicators light up, indicating which stage is operating. Once all stages have been completed, the final indicator extinguishes and the screen displays the “Cycle Finished” message.

The process will not start if:

• The door is not closed and the DOOR CLOSED indicator is off.

• The “DOOR UNLOCK” message is displayed. Note: Due to inherent elasticity of the door gasket, the

CLOSE DOOR indicator may be illuminated green before a complete seal is made between the door and the chamber. Therefore, in order to ensure the door is fully sealed, tighten the door bolt until ‘hand tight’. Do not overtighten the bolt as this may result in damage to the gasket. Should the autoclave fail to reach sterilizing temperature/pressure, always check first if the door is fully sealed. If not, tighten the door further, as described above, until completely sealed.

• There is not enough water in the reservoir, (the red ADD WATER indicator lights and the “ADD WATER” message is displayed).

20

(13) STOP This key issues the only command accepted by the system

during the running of a program. Pressing this key for over 1 second causes the program to immediately cease running and enters the EXHAUST stage, at the end of which the “MAN. STOP” message will be displayed. This key has no function when the system is not in operation and its only use is to manually stop a cycle. In normal working conditions on completion, the system automatically terminates the cycle, without use of this key.

The STOP key does not function in EXH stage.

3.3 Description of the Display Panel

The display is comprised of 16 characters in one row and is divided into 4 sections.

The first section to the right, continuously shows the actual pressure within the chamber. This happens whether the system is running a program or not (provided the main power switch is turned on).

The three other sections are designated to show the parameters of the selected program, or operating messages. When the system is running a sterilization program, the sterilization temperature will be displayed above the TEMP key. Sterilization time will be displayed above the STE. TIME key and the drying time for the selected program will be displayed above the DRY TIME key.

If the program is aborted as a result of parameters exceeding the controlled limits (high, low pressure or temperature etc.) or a manual STOP command, a message is displayed on the left side of the screen. When a message is displayed, pressing any key erases the message and redisplays the selected program screen.

When the system is running a program, the screen displays the current temperature within the chamber and the remaining time for sterilization or drying. The current real pressure inside the chamber is always displayed on the screen.

3.4 Description of Displayed Messages and Safety Measures

Low Heat Message is displayed and sterilization does not start if the autoclave has not reached sterilization temperature after heating for 50 minutes while in the Wrapped or Unwrapped programs (80 minutes in the Glassware program).

Possible causes: ♦ A clogged Air Jet (see cleaning the Air Jet sec 9.4). ♦ No power to the heating elements. ♦ Low line voltage delaying heat up.

Low Pres Message is displayed, fail indicator lights, and the program is aborted if the pressure drops 4 psi (0.27Bar) below the required sterilization pressure.

Possible causes: ♦ Insufficient water in the chamber (see Low Water message). ♦ A damaged heating element. ♦ A damaged pressure transducer.

21

Low Temp. Message is displayed, fail indicator lights and cycle is aborted, if the temperature drops 2.5°C (4.5°F) below the required sterilization temperature.

Possible causes: ♦ Insufficient water in the chamber (see Low water message). ♦ Sterilization time has been set for too long a period. ♦ A bad temperature sensor.

High Temp. Message is displayed, fail indicator lights and program is aborted if one of the following occurs: ♦ The temperature rises to 3°C (5°F) above the required

sterilization temperature during the sterilization stage. ♦ This message appears during the HEAT stage, if the

temperature sensor is damaged. Possible causes:

♦ A damaged solid state relay. ♦ A damaged heating element. ♦ A damaged temperature sensor.

Low Water Message is displayed; if during the Water Inlet stage, insufficient water enters the chamber. In units with water pumps, the pump will try three times to fill the chamber with water, if unsuccessful the cycle is aborted and the message LOW WATER is displayed.

Message is displayed, if during a normal heat up stage the system determines that there is insufficient water in the chamber to complete the cycle. This determination is made by the combined input of two sensors, the Water Electrode and the Safety Thermostat. Also, if a power failure occurs during the heat or sterilization stage after the power returns, the system will check the Water Electrode to see if there is sufficient water in the chamber in order to resume the cycle. If not, the cycle will be aborted, the message LOW WATER will be displayed, and the Cycle Fail indicator will light.

Possible causes: ♦ A dirty or shorted Water Electrode. ♦ A clogged water pump or water pump filter. ♦ A clogged water line. ♦ Unit is improperly leveled. ♦ The Air Outlet Valve is stuck closed. ♦ A leaky door gasket, door bellows, solenoid valve, safety

valve, or the air jet is allowing steam to escape at a higher than normal rate.

♦ A power down has occurred and on power up the water electrode tip is dry.

22

Door Unlock Message is displayed and the DOOR CLOSED LED indicator remains unlit, if the door is improperly closed when the START button is pressed. If the door accidentally opens during any stage of the cycle, the same message appears, the DOOR CLOSED LED indicator will turn off, and the system reacts as if the STOP key was pressed.

High Pres. Message is displayed, fail indicator lights up, and the program is aborted if the pressure rises 10 PSI (0.6Bar) above the required sterilization pressure.

Possible causes: ♦ A damaged solid state relay. ♦ A damaged heating element.

Man. Stop Message will be displayed and the FAIL indicator will light after the STOP key is pressed for longer than 1 second.

Add Water Message is displayed and the respective red LED indicates insufficient water in the water RESERVOIR. After water is added to the reservoir, the START button must be pressed again in order to start the required sterilization cycle.

Water Inlet During the automatic water fill, the message WATER INLET is displayed as information to the operator.

Power Dn. If a power failure occurred during the running of a cycle, when power resumes, a POWER DN message is displayed for several seconds; if a printer is installed it will print POWER DN. In addition, the system automatically attempts to complete the STERILIZATION stage if the following parameters are met: a. If the temperature drop is less than 4.5°F (2.5°C),

sterilization resumes automatically. b. If the temperature drop is more than 4.5°F (2.5°C), the

cycle fails, POWER DN message is displayed and printed and LOW TEMP message is displayed.

c. If the pressure drop is more than 4 psi (0.27 Bar), the cycle fails, POWER DN message is displayed and printed and LOW PRES message is displayed.

If a power failure occurred during the HEAT stage, heating resumes, provided enough water remains in the chamber. If not, the cycle is aborted, the message “LOW WATER” is displayed. If a power failure occurs during the dry and exhaust stages, the unit will automatically resume operation once the power is back on.

If a power failure occurs during the GLASSWARE PROGRAM, the system does not allow fast exhaust (as the exhaust valve is normally closed) during a power failure or when power resumes.

CYC Finish When the cycle has been completed successfully the message CYC FINISH is displayed.

23

4 STERILIZATION PROGRAMS The autoclave offers 3 sterilization programs, at temperatures of up to 274°F

5 PRINTER (Optional) The printer is an optional device. If the autoclave is not equipped with a printer,

paragraph 5 is not applicable.

5.1 Printer Operation The autoclave is equipped with a character printer that prints a detailed

history of each cycle performed by the instrument (for the record or for subsequent consideration).

The printing is made on thermal paper with 24 characters per line and

contains the following information: ♦ Software version. ♦ Date and time of cycle start. ♦ Selected program and parameters. ♦ Sterilization pressure. ♦ Sterilization temperature. ♦ Sterilization time. ♦ Cycle identification.

When the sterilization cycle begins, the printer starts printing the above

data. After the preliminary printing, the autoclave starts performing the

sequence of operations of the cycle. The measured values of temperature and pressure are printed at fixed time intervals, according to the phase of the process, as shown in the table below.

The data is printed from the bottom up, beginning with the program name and ending with “O.K.” for a complete cycle, or “FAIL” for an aborted cycle.

For an example of a typical printout, see next page.

5.2 Printer Handling The printer is driven and controlled automatically by the control unit,

while the autoclave performs a sterilization program.

Figure 1 Figure 2

To set the paper roll in the printer, perform the following steps:

5.2.1 Gently push the clips for removing the front panel, remove the panel and pull out the printer gently.

5.2.2 Set the paper roll on the shaft (See Figure 1). Since the outer and inner surfaces of the paper are different, set the roll so that the printing surface is the outer.

5.2.3 Gently push the paper face down into insertion opening (A) in Figure 2. Keep pressing the feed switch (B) until the paper comes out from the print head (C).

5.2.4 When the paper emerges from the print head, insert it in the paper cutter (the slot in the front panel) and reassemble the front panel on the unit.

The paper roll is set inside the unit and the printer is ready for use.

NOTE: If the paper is not pulled in by the rollers, even when you press the feed switch (B), push the paper in.

5.2.5 To ensure a reliable operation of the printer, perform the following: 5.2.5.1 Turn the main switch to the OFF position.

5.2.5.2 Press the feed switch and at the same time turn the main switch to the ON position. Verify that the printer performs an operation test by printing all the built-in characters.

The following precautions have to be taken to ensure the proper operation of the printer: ♦ Avoid contact between the paper and the hot parts of the autoclave,

as the paper will be blackened.

♦ Do not pull out the paper roll from the paper insertion opening.

♦ Use only the 58mm. wide thermal paper rolls, supplied by your dealer. Larger rolls will not fit inside the printer.

29

6 INSTALLATION INSTRUCTIONS

Caution: The sterilizer must be placed on a rigid and leveled surface. The stand must be able to hold the load of the device and loaded material.

Note: Make sure while placing the autoclave, to leave space around the machine, to give the technician access to service the machine.

6.1 Electrical The electrical connection should comply with the device’s power

requirement. It must also comply with local installation and safety rules and regulations. The voltage supplied to the device must comply with the label ± 5%.

In order to avoid any injury by electrical hazard, it is mandatory for the

customer to have installed an earth leakage relay (GFI outlet or circuit breaker) in the electrical circuit to which the autoclave is connected. This relay disconnects all the poles of the electrical power line in case of accidental contact with the autoclave’s metal enclosure, by the operator or another person, leading to a dangerous leakage current.

Note: Keep the back and the right side of the autoclave approximately 1”

(25mm) away from the wall to allow for ventilation.

Connect the power cord to the socket on the rear side of the autoclave; plug it into the supply outlet. The autoclave must be connected to a properly grounded outlet.

6.1.1 Setup for new units 2340, 2540, 3140, 3850 & 3870 Your new Tuttnauer Autoclave was set at the factory and requires a

minimal of setup. ♦ Make sure the counter is level and sturdy. ♦ Make sure all the feet are on the autoclave and none have been

lost. ♦ Position the autoclave on the counter. ♦ Fill the reservoir with distilled water (see sec 6.5). ♦ The unit is ready to operate.

30

6.1.2 Setup for units 1730 and any unit with serial number prior to 2003000

Proper adjustment of the chamber pitch is one of the most important things you can do for the sterilizer. Proper chamber pitch insures that among other things the sterilizer will have the proper amount of water in the chamber at the beginning of each cycle. Insufficient water in the chamber at the beginning of the cycle will generate a LOW WATER message at some point during the cycle when the water level becomes too low. If, on the other hand, there is too much water in the chamber this will extend the heating portion of the cycle. In cases where the heating portion of the cycle is extended for more than 50 minutes (80 minutes for a 3850/3870) the sterilizer will abort the cycle and display a LOW HEAT message. Please follow these setup steps:

♦ Make sure the counter is level and sturdy (3). ♦ Make sure all the feet are on the autoclave and none have been

lost. ♦ Make sure the feet are free to move in and out (2). ♦ Position the autoclave on the counter. ♦ Fill the reservoir with distilled water (see sec 6.5). ♦ The chamber should be empty of any instruments, trays or

leftover water. ♦ The autoclave should be turned off. ♦ The chamber pitch now needs to be adjusted. ♦ Measure to the proper amount of distilled water for the

appropriate model unit as listed below (the tolerances on these amounts are +2 oz. and –0 oz).

1730 2340/2540 3140 3850 3870

10 oz 300 ml 12 oz 350 ml 14 oz 400 ml 20 oz 600 ml 24 oz 750 ml.

♦ Pour the proper amount of water into the chamber through the front door of the unit (4).

♦ This water should cover the bottom of the chamber to within +/- ½ inch of the groove in the front. (1).

♦ If necessary, adjust the front leveling feet so that the water lays in the chamber correctly. (2).

♦ Once the chamber pitch adjustment is completed, empty the water from the chamber and check if the automatic filling is set correctly. See sec 6.2.3.

31

6.2 Automatic Water Filling

6.2.1 For new units 2340, 2540, 3140, 3850 & 3870

The proper amount of water for automatic filling in your new Tuttnauer autoclave has been preset at the factory. However, if in routine operation there is inadequate water in the chamber, the operator can adjust the level with the automatic built-in system by doing the following:

1. Press STOP key repeatedly until the message “code xxx” appears on the display.

2. Use the UP or DN arrow keys to change the code to 105, then press the STOP key.

3. A message will be displayed saying “Water in = xx sec”. 4. Press UP or DN keys to increase or decrease water inlet time. 5. Press the STOP key to enter new water inlet time into memory. 6. If necessary, press the STOP key again to bring up the program

display.

Note: DO NOT attempt to automatically fill the chamber with the

DOOR open. Water will overflow out of the chamber.

Warning: If it becomes necessary to RESET the software program, it will be essential to repeat all steps listed above. This will ensure that the correct amount of water enters the chamber for operation.

6.2.2 For units 1730 & any unit with serial number prior to 2003000

If it becomes necessary to adjust the automatic fill, follow these steps:

1. Make sure the power is off. 2. The door should be open and the chamber empty of any water. 3. Make sure the Water Electrode is clean (see sec 9.10). 4. Press and hold the Water Inlet key (this is the button on the

keypad with the two arrows). 5. Turn the power on. When the program display screen appears,

release the Water Inlet key – wait one second and press it in again.

6. Water will begin flowing into the chamber. 7. Monitor the water flow. 8. Hold the Water Inlet key until the water reaches the groove at

the front of the chamber. 9. Release the button – wait ten seconds – the unit is now

reprogrammed.

32

6.2.3 Checking the automatic fill

To check the automatic fill, follow these steps: 1. Remove any water that is in the chamber. 2. Make sure the unit is turned on. 3. Place a collecting vessel under the autoclave’s door. 4. With the door open, press and hold the door switch, then

press the START key. 5. When water starts flowing into the chamber, release the door

switch. 6. Water should come beyond the groove at the front of the

chamber, and a small amount will pour into the collecting vessel.

7. After the automatic filling is completed, tilt the autoclave and pour all the water in the chamber into the collecting vessel.

8. Measure and verify that the amount of water pumped into the chamber is 500-600 ml.

9. If the water is not filling correctly, follow the adjustment procedure above.

Warning: If it becomes necessary to RESET the software program, it will be essential to repeat all steps listed above. This will ensure that the correct amount of water enters the chamber for operation.

VERY IMPORTANT – Due to the fact that the water lines are empty when the unit is shipped, air may become trapped in the lines. It is recommended that, for the first operation, these steps are followed to make sure water is flowing freely.

Open the door, press the Water Inlet key. When water enters the chamber, release the key and remove the water.

6.3 Lifting and Carrying

Caution: Before moving the autoclave, make sure that the electric cord is disconnected from the power and there is no pressure in the chamber. 1. Disconnect the power supply cord. 2. Drain the water from the reservoir and vessel.

To avoid injuries, lifting and carrying should be done by two people. Do not drop this device!

33

6.4 Loading and Unloading the Device

6.4.1 Safety Protective equipment, clothes and other safety instructions should

be implemented in accordance with local and national regulations and/or rules!

For proper sterilization — Do not overload the chamber. Only autoclavable products shall be used; please refer to the material or instrument manufacturer’s instructions for sterilization of unknown materials or instruments.

6.4.2 Loading Correct loading of the autoclave is essential to successful

sterilizing for several reasons. Efficient air removal from the chamber and the load will permit steam penetration and saturation, and allow proper drainage of condensate. Additionally, correct loading will reduce damage to packs and their contents and maximize efficient use of the sterilizer.

For detailed loading instructions, see sec. 7 (Preparation before sterilization).

6.4.3 Unloading On completion of the cycle, the load shall be immediately

removed from the sterilizer and a visual inspection made to ascertain that the load is dry, and that sterilizing indicators have made the required color change.

6.5 Filling the Water Reservoir

Remove the water reservoir cover. Pour distilled water into the reservoir through the opening on top of the autoclave until it reaches the base of the safety valve holder, approximately 0.7 gallons (3 liters).

Use water-having characteristics as per table in sec 2.11. Caution: Under no circumstance should water be filled above the safety valve holder.

USE DISTILLED WATER ONLY. The impurities in tap water will create the need for more frequent cleaning and maintenance, in addition, they will accumulate and block the hole of the Air Jet. This will prevent the temperature in the chamber from rising properly. This will cause the unit to abort its cycle, spore tests to fail and indicator strips not to change color. It is essential from time to time during heating and sterilization phases that a spray of steam should escape, from the Air Jet, causing a hissing sound. If no escaping steam is evident or no hissing sound heard, follow the instructions in sec 9.4 for cleaning the Air Jet.

7 PREPARATION BEFORE STERILIZATION The purpose of packaging and wrapping items for sterilization is to provide an

effective barrier against contamination during storage, once the items have been sterilized.

Instruments to be sterilized must be free from all residual matter, such as blood or organic tissue. Instruments must also be dry and free from mineral deposits. Such substances may cause damage to the instruments themselves or the Sterilizer.

1. Clean instruments immediately after use to remove any residue. It is recommended that all instruments be ultrasonically cleaned using Tuttnauer’s CLEAN AND SIMPLE enzymatic cleaning tablets or other suitable solution.

2. After cleaning, rinse instruments under tap water for 30 seconds and pat or air dry to remove residual minerals. If your tap water has a high mineral content, rinse a second time in a bath of distilled water to remove minerals.

3. Launder textile wraps prior to reuse, but do not use bleach.

4. Follow the instrument manufacturer’s instructions on the use of products for cleaning and lubricating instruments that have been ultrasonically cleaned.

5. Be sure that instruments of dissimilar metals (stainless steel, carbon steel, etc.) are separated. Carbon steel instruments should be bagged or placed on autoclavable towels and not directly on stainless steel trays (mixing will result in the oxidation of these metals).

6. Do not place materials to be sterilized against the chamber’s wall. Place the material only on the tray or rack.

7. When using a paper / plastic bag, the plastic side should always be down.

8. Check the instructions of the item manufacturer as to the proper procedure for sterilizing each item.

9. Items must be sterilized in an open position. Surfaces that are hidden because the item is in a closed position will not be exposed to the steam and will not be sterilized.

10. Place a sterilization indicator in each tray or inside each wrapped pack.

11. At least once a week use a biological spore test (Bacillus Stearothermophilus) in any load to insure proper sterilization. (Be aware, testing standards may vary). Always follow the spore test manufacturer’s instructions.

12. Make sure that all instruments remain apart during the sterilization cycle. Surfaces that are hidden because items are covering other items will not be exposed to the steam and will not be sterilized.

35

13. Verify that packaging methods are in accordance with the good practice approach and the packaging materials used are in agreement with applicable standards.

14. Empty canisters should be placed upsidedown in order to prevent the accumulation of water.

15. Do not overload the Sterilizer trays. Overloading will cause inadequate sterilization & drying.

16. Allow a distance of approximately 1″ between trays to permit steam circulation.

17. Wrapped instruments should be placed in material which will allow steam penetration and promote drying, such as autoclave bag, autoclave paper, or muslin towels.

18. Do not stack pouches. It is recommended that a pouch rack such as the Tuttnauer POUCH RACK be used to insure proper steam penetration and adequate drying. Surfaces that are hidden because the items are being stacked will not be exposed to the steam and will not be sterilized.

19. Tubing should be rinsed after cleaning. When placed in the tray, make sure that both ends of the tubing are open and there are no sharp bends or twists.

20. Packs should be placed upright on the tray. They should not be touching each other or the Chamber walls. There should be about 1” between packs for proper steam circulation.

For models 2340, 2540 For model 3870

36

21. If spotting is detected on the instruments, the first step would be to use an ordinary eraser to remove the spot. If there is no pitting under the spot then the spot was only dirt. Dirt spots on an instrument may be an indication that the autoclave needs to be cleaned or that the instruments were not adequately cleaned or dried. If removal of the spot reveals pitting, the spot was most likely rust. Rust spots on an instrument are not uncommon on inexpensive instruments. It may also be an indication that the instruments were rinsed in tap water with a high content of minerals. These minerals, when exposed to high temperature and steam, will accelerate the oxidation of the metal. One suggestion would be to final rinse the instruments in a distilled water bath.

22. If the instruments exhibit a discoloration, this can be due to the mixing of carbon steel and stainless steel. When these two metals come into contact with each other an electrolysis occurs that breaks down the metal. The best solution is to separately wrap the carbon steel to insulate it from other instruments or the trays.

23. Items should not be allowed to touch the walls of the Chamber as the hot metal can damage the item.

37

8 OPERATING INSTRUCTIONS It is important to clean the hole of the air jet, as described in sec. 9.3 before

starting operation of the autoclave for the first time. 1. Remove water reservoir cover. Pour distilled water into the reservoir,

through the opening on top of the autoclave, until it reaches the base of the safety valve holder, approximately 0.7 gallons (3 liters).

2. Plug the power cord into the back of the autoclave and into the wall outlet.

3. Turn on the rocker switch mounted on the bottom of the front panel.

4. If a printer is installed, set the clock with the proper date and time.

5. Press the required key to select the required program. The light indicator of the selected program is illuminated; indicating the program has been selected. The preset data of the program, sterilization temperature, time and dry time are displayed.

6. Load the material to be sterilized into the chamber according to instructions in sec. 7 (Preparation Before Sterilization) and close the door making sure the ‘Close Door’ indicator is illuminated. NOTE: Due to the inherent elasticity of the door gasket, the CLOSE DOOR indicator light may be illuminated green before a complete seal is made between the door and the chamber. Therefore, in order to ensure that the door is fully sealed, when the green light has been illuminated continue to tighten the door bolt until “hand tight”. Do not overtighten the bolt as this may result in damage to the gasket. Should the autoclave fail to reach the sterilizing temperature/pressure, always check first that the door is fully sealed. If not, tighten the door bolt further, as described above, until completely sealed.

7. Press the START key to put the autoclave in operation. WATER INLET is displayed until the correct volume of water is

automatically introduced. The autoclave starts performing the sequence of operations. The actual

measured values of pressure and temperature are displayed continuously (and printed with optional printer).

The indicator lights HEAT, STE, EXH and DRY are turned on and off as each stage is started and completed. NOTE:

It is possible to change parameters, only when the autoclave is not in operation. In order to change the fixed preset parameters, proceed as follows:

To increase or decrease the sterilization temperature, sterilization time or dry time, follow instructions from sec. 3.2.2.

Pressing the UP/DN key, advances the setting upward or downward by one unit. The displays are updated with every change in the preset data.

8. During any program that has a drying stage scheduled, the dry stage begins after the steam exhaust stage. Models EA or EKA are equipped with an air compressor, that during the drying stage, draws air through a HEPA filter (0.2µm), pushes that air through the heated chamber and out the air outlet valve to remove moisture and facilitate the drying operation. Drying is performed with the door closed.

38

8.1 To obtain better drying results from the E and EK models, during the dry stage open the door partially (as described below) at an angle of approx. 20-25 degrees. The heaters will be on at a lower power level and water vapor and humidity will be evacuated from the chamber efficiently.

Without moving the closing device from its position, unscrew the closing device as far as it will go. Allow the door to open to the maximum that the closing device will allow (see picture).

9. At the end of the cycle a buzzer rings for approximately 5 seconds, the START light switches OFF. The air outlet valve is opened to prevent formation of a vacuum.

In the event of a program failure, the exhaust valve is opened to release pressure from the chamber and a continuous buzz will sound for 5 seconds followed by an interrupted buzz of 7 seconds.

10. Open the door and unload the sterilized material from the chamber.

11. The sterility of instruments processed in unwrapped cycles cannot be maintained if exposed to a non-sterile environment.

Note: A minimum time interval of 10 minutes needs to be observed between the

end of a cycle and the start of a new cycle, to prevent overheating of the autoclave.

Do not touch the strainer’s cover, mounted on the exhaust line, during and shortly after operation, it will get very hot.

Touching the hot strainer’s cover may cause severe injuries.

9 MAINTENANCE INSTRUCTIONS

9.1 Preventive and Scheduled Maintenance The maintenance operations described in this chapter need to be followed,

as indicated, to keep the device in good working condition.

The instructions that follow can easily be carried out by the office personnel and do not require a service technician.

Should the need arise, technical assistance or a service technician can be requested by either calling your dealer or Tuttnauer USA.

9.1.1 Daily 1. Clean the door gasket with a mild detergent, water and a soft

cloth or sponge. The gasket should be clean and smooth.

9.1.2 Weekly 1. ONCE PER WEEK, clean the air jet. To ensure that the

temperature inside the chamber rises properly it is necessary to keep the air jet clean. A dirty air jet will prevent indicator strips from changing color and cause spore tests to fail. See sec. 9.4.

2. Clean the water sensor in the rear of the chamber with a damp cloth or sponge. Cleaning the dirt off the sides of the sensor is more important that the tip (see sec 9.10).

3. Once per week clean and descale the chamber, copper tubes and the reservoir using Chamber Brite (see sec. 9.9).

4. Take out the tray holder and trays. Clean the tray holder and trays with detergent or a non-abrasive stainless steel cleaner and water, using a cloth or sponge. Rinse the tray holder and trays immediately with water to avoid staining the metal.

Caution Do not use steel wool, steel brush or bleach as this can damage the chamber and trays!

5. Put a few drops of oil on the 2 door pins and door tightening bolt.

6. Clean the outer parts of the autoclave with a soft cloth.

9.1.3 Periodically 1. Once every month clean and check the safety valve. 2. On EA and EKA models replace the air filter every 6 months,

or as needed (see sec. 9.2). 3. Replace the door gasket every 12 months, or as needed (see

sec. 9.5). 4. Once every six months clean the fan grid with compressed air

from the inside outward. 5. Clean strainer once a month as per sec. 9.8. Cleaning

frequency may be reduced according to previous maintenance.

6. Once a year inspect the locking device for excessive wear.

41

9.2 Replacing the Air Filter (Models EA, EKA) To facilitate drying the instruments with the door of the chamber closed,

models EA and EKA are equipped with an air compressor and HEPA filter (0.2µm). During the drying stage the compressor draws air through the HEPA filter and forces the circulation of that air through the heated chamber to remove moisture from the wrapped instruments. The filtration of the air is performed by the bacteriological filter. Frequency of replacement will be determined depending on the usage of the autoclave and the surrounding environment.

The filter is mounted in an opening on the right sidewall of the autoclave enclosure, this is to allow easy access for replacing it, (see picture below).

To replace the filter proceed as follows:

1. Remove the filter cover (2) by turning the cover counterclockwise until it is released.

2. Remove the filter (5) from the filter cover by pulling the filter apart from the filter cover

3. Cut the tie wrap (4) fixing the flexible tube (3) connecting the filter to the copper pipe, and pull off the filter.

4. Replace the filter with a new one. Connect the filter (5) to the flexible tube (3) and tighten it with a tie wrap (4).

5. Connect the filter to the filter cover by pressing the filter (5) into the hole in the cover (1).

6. Insert the filter to its place inside the autoclave and reassemble the filter cover by turning it a ¼ turn clockwise. Verify that the cover is fastened well in its place.

9.3 Draining the Reservoir

Caution Before starting, ensure that the electric cord is disconnected and there is no pressure in the autoclave.

The drain valve is located on the front left side of the autoclave after the door is opened. The function of the drain valve is to drain the water reservoir.

1. Connect the silicone hose, supplied with the autoclave, to drain into a

bucket. 2. Turn drain valve counterclockwise to the open position. 3. Fully drain the reservoir. 4. With a quart of tap water, flush out the reservoir. 5. Turn drain valve clockwise to the close position. 6. Connect the electric cord to power source. 7. Fill the reservoir with distilled water to just below the safety valve (see

sec 6.5). 8. Turn on the main power switch. 9. The autoclave is now ready for use.

43

9.4 Cleaning the Air Jet (Located in the water reservoir.) A dirty air jet is the number one cause of failed spore tests

The elimination of air from the sterilization chamber during heat up is critical to the proper operation of the autoclave. Failure of the air removal system will be responsible for incomplete sterilization, indicator strips that do not turn, failed spore tests and aborted sterilization cycles. A clogged air jet will result in receiving the error message “Low Heat”.

The air jet consists of a small orifice with a clean out wire inserted in it

(wire is permanently installed and will not come out). It is required that the air jet be cleaned once per week or more often if necessary, to remove any accumulated dirt and debris.

It is preferred to clean the air jet when the unit is running a cycle and

under pressure. Any loosened debris will be blown away, however, it can be done while the unit is idle.

1. Remove the water reservoir cover. 2. Clean the hole of the jet by manipulating the air trap wire back and forth

10 times.

It is important to clean the hole of the air trap, as described at point 2 before starting operation of the autoclave, for the first time.

44

9.5 Replacing the Door Gasket

Pull off the gasket from the door groove. Install the new gasket as described in drawings 1, 2 and 3 above.

Caution! This gasket is designed with a trapezoidal cross section. The gasket should be placed with the widest side towards the door.

45

9.6 Checking the Safety Valve (Located in the water reservoir) In order to prevent the safety valve from becoming blocked, it is

necessary to allow the steam pressure to escape through the valve. This procedure should be done every month as follows: 1. Operate the sterilization cycle according to the manual. 2. Allow a pressure of approximately 30 psi (260 kpa ) to build up in the

chamber. 3. Turn the unit off. 4. Remove water reservoir cover. Caution! This next step will expose you to HOT STEAM.

Caution! To avoid being burned by hot steam, do not place your face over the safety valve. 5. Pull the ring of the safety valve using a tool, i.e. screwdriver, hook, etc.,

and open the safety valve for 2 seconds, then release. Be careful not to burn your hands.

6. Turn the unit back on and press the STOP key to abort and vent the cycle.

7. Wait until pressure decreases to zero, only then can the door be opened.

46

9.7 Replacing the Fuse Caution Make sure that the electrical power cord is disconnected!

Use a screwdriver to unlock the fuse holder cover by turning it counterclockwise ¼ turn, and pull it out.

Insert a new fuse into the holder and turn the cover clockwise until locked.

Make sure that the correct fuse is installed

1. Water Pump Fuse: 1.25 amps. 2. Air Pump Fuse: 2.0 amps for 120V. 1.25 amps for 230V.

For autoclaves Models E, EK

(without an air pump)

For autoclaves Models EA, EKA (with an air pump)

9.8 Cleaning Water Outlet Strainer

Caution! Before proceeding, make sure that the electric cord is disconnected and there is no pressure or water in the chamber.

Warnings 1. The strainer’s cover is HOT Do not touch the strainer’s cap, mounted on the exhaust line, during and shortly after operation. Touching the hot strainer’s cap may cause severe injuries. 2. If maintenance operation is performed while strainer cap is hot, use heat resistant gloves to avoid injuries.

1. Open the strainer cap. 2. Remove the strainer element. 3. Rinse the strainer with water, using a brush if necessary. 4. Reinstall the strainer element. 5. Close the strainer cap. .

9.9 Cleaning Tabletop Autoclaves with Chamber Brite ™ CHAMBER BRITE™ is a cleaning and descaling agent designed

specifically for the cleaning and removal of water deposits, oxides and other sediments that are found in steam sterilizers. The material is a combination of acidic salts and additional cleaning materials. Chamber Brite ™ autoclave cleaner has been formulated specifically to be a fast, powerful and easy to use cleaner for steam sterilizers.

If the autoclave is not cleaned regularly, dirt and debris will build up and

clog the tubing and solenoid valves. This dirt can also be transmitted to the instruments during sterilization. In addition, a layer of dirt on the stainless steel chamber traps moisture against the metal and will lead to the chamber becoming porous and failing.

It is recommended that your autoclave be cleaned with CHAMBER BRITE ™ once per week. Caution! NEVER use bleach, steel wool, a steel brush or anything abrasive to scrub or clean the Chamber.

Cleaning Procedure 1. Important – all steps in this procedure

must be completed without interruption. 2. When the autoclave chamber is cold,

remove instruments and trays from the autoclave.

3. Open the door and spread the contents of a packet in a straight even line along the bottom of the chamber, from back to front.

4 Select and start program No. 1. (without dry). When the cycle is finished it will automatically exhaust.

5. At the end of the exhaust cycle drain the water from the reservoir.

6. Fill the water reservoir with distilled water.

7. Repeat a sterilization cycle without Chamber Brite ™ powder, to remove any excessive dirt in the pipes. Select and start program No. 1. (without dry). When the cycle is finished it will automatically exhaust.

8. At the end of the exhaust cycle, drain the water from the reservoir.

9. Turn the autoclave off and allow chamber to cool. 10. Remove the tray holder; rinse and wipe the interior of the chamber

with a damp cloth.

49

11. Fill the reservoir with distilled water or mineral free water only. 12. Press the manual water fill button and allow a small amount of water

(2-4 ounces) to fill chamber and flush out the fill tube. Remove water from chamber.

13. The instrument is ready to use. IMPORTANT: DO NOT sterilize instruments during the cleaning process!!!

CAUTION: Keep out of reach of children. Contains mildly acidic ingredients. Avoid contact with the skin, eyes or clothing. Wash hands well after touching the powder, in the case of eye contact flush with continuous running water for at least 15 minutes. If irritation persists get medical attention. If accidentally swallowed, do not induce vomiting, drink large amounts of water and obtain medical attention. MSDS available upon request.

For models 1730, 2340, 2540 use one packet of CHAMBER BRITE ™. For models 3140, 3850, 3870 use two packets of CHAMBER BRITE ™. Clean every 20 cycles or as needed.

50

9.10 Water Sensor Cleaning It is required that the water sensor be cleaned at least once per week. Cleaning the sensor will ensure that the water level in the chamber is properly reported to the microprocessor all during the cycle.

The water sensor is located in the rear of the chamber. It is easily cleaned using a damp cloth or sponge, you may use a mild soapy solution if you like. It is important to wipe the sides of the sensor as well as the tip, to remove any dirt or debris that may have built up.
