• Page 17: Description Of The Central Control Unit

  3. Description of the central control unit The DFZ ZANOTTI refrigeration units are equipped with a microprocessor-based electronic controller (driver’s cabin control) which manages operation in a fully automatic way. In particular, the electronic controller supervises the operations for turning the diesel engine and electric motor on and off depending on the set temperature.

• Page 18: Operation

  4. Operation 4.1 Before operating the unit 1. Check the belts. In fact, their tension must be perfect in order to prevent them from slipping if they are too slack (as this would generate heat and would therefore shorten the life of the belts) or the bearings from wearing out too fast if the belts are too tight.

• Page 19: Setting The Unit At Work

  4.2 Setting the unit at work Press push-button 1 to turn on the driver’s cabin control. The mask shown in f i g . 2 will appear after a few seconds. This mask shows: • TA1: Cold room temperature • SP1: operating set point •…

• Page 33: Goods Loading Procedure

  Avoid positioning the goods leaning on the cold room walls. In fact, the walls fil- ter heat from the environment, which is most damaging to this type of goods. The DFZ ZANOTTI refrigeration units are designed to keep the goods at their loading temperature.

• Page 34: Tips On The Temperatures Of Carried Goods

  • 0/15 cm (4/6 in) is the minimum clearance between the cargo and the walls of the cold room. • When parking, leave your vehicle in the shade and make sure that the DFZ ZANOTTI refrigeration unit does not remain idle for a long time.

• Page 35: Using The Unit Safely
