Preliminary information Thank you for choosing one of the models of DFZ ZANOTTI refrigeration units. This manual is addressed to the operators of DFZ ZANOTTI refrigeration units. Inside you will find the necessary information to use and service the products correctly, safety tips, warranty terms as well as suggestions on the best way of transporting your goods. If you follow such instructions, you will be able to minimize the service operations required and to extend the life of your unit.
Safety Tips By drilling the walls of the unit or the isothermal cold room, you could damage the electric wires or the refrigeration piping. Should such action be strictly necessary, great care should be taken to avoid any damage. Touching turning fans and moving belts can cause irreparable damage or injury. Be careful with the blades of the condenser and evaporator; their edges are very sharp.
Engine The PERKINS engines fitted on all DFZ ZANOTTI refrigeration units are designed to keep pollution caused by exhaust gas at a minimum level. However, we strongly recommend to avoid starting the engine in a confined area, as the exhaust gas is toxic. The symptoms caused by carbon monoxide produced by fuel combustion are the following: – dizziness – strong headache – sleepiness – vomiting. If you should experience these symptoms with the engine on, try to breath clean air immediately.
How to order spare parts When ordering spare parts, always include the serial number shown on the machine's rating plate.

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. Operation selection (diesel or electric) is automatically carried out by connecting the provided plug to the mains. fig. 1 3.
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. It is a very easy check: pressing slightly at the center of the longest side of the belt, there should be a slack of 8 to 12 mm (5/16 in. to 15/32 in.
4.2 Setting the unit at work Press push-button 1 to turn on the driver's cabin control. The mask shown in fig. 2 will appear after a few seconds.

5. Goods loading procedure 5.1 Storage and stacking One of the main concerns to take into account when storing goods, is how to ensure proper air circulation in the isothermal cold room. If the air cannot circulate freely throughout the cargo, ice or warm areas will almost certainly develop, which could irreparably damage the goods. One of the first tips to avoid this, is to store the goods on pallets.
5.3 Tips on temperature of carried goods Product -Reference temperature Bananas -15°C (55/60°F) Fresh fruit and vegetables -4/6°C (39/43°F) Fresh meati and seafood -2°C (36°F) Milk and dairy products -2/6°C (36/43°F) Ice-cream -20/-25°C (-15/-20°F) Deep frozen fruit and vegetables -18°C (0°F) Deep frozen meat and fish -20°C (-10/0°F) THESE TEMPERATURES ARE FOR REFERENCE PURPOSES ONLY. ANY TEMPERATURE SUPPLIED BY RECEIVER OR CARRIER WILL PREVAIL. GB 5.
6. Using the unit safely The DFZ ZANOTTI units are built to keep the operators safe. The use of protection gloves is, in any case, fundamentally important during controls, repairs, and maintenance for every action which the operator must carry out inside the unit, whether when handling the evaporator or the condenser which can injure his hands with their fins or to avoid burns caused by accidental contact with the unit's hot parts. 6.
