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 mini-
mize the service operations required and to extend the life of your unit.
ZANOTTI reserves the right to change the above data without previous notice.
Important safety warnings
Below you will find some recommendations concerning your safety as well as
instructions to follow when installing and using your machine.
Installation
When installing the unit, take all the necessary precautions (for example, lad-
ders, safety belts, helmets and protection gloves). The unit is fitted in the corre-
sponding hole on the cold room; you just have to introduce the monoblock refrig-
eration unit into the existent hole and fix it by using the standard bolts and nuts
supplied with the product.
Battery
If the refrigeration unit is left idle for some time, we recommend turning off the
machine by pressing the ON/OFF button located on the electronic control unit
first and then button 1 (fig.1).
In this way, the electronic control unit is completely de-energized, thus protecting
the battery. Disconnect all electric circuits and both batteries (vehicle and refrig-
eration unit) before attempting any welding operation.

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 nec-
essary, 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.
The refrigeration oil used is a synthetic, mineral-base oil; it can irritate the skin in
case of long contacts or if after coming into contact with oil, the affected areas
are not carefully washed.
Refrigerant
Some special safety warnings need to be reminded concerning the refrigerant.
DO NOT HANDLE THE REFRIGERANT BEFORE READING THE NOTES
BELOW.
If heated, the refrigerant gives off a gas that irritates the respiratory system.
Never heat a closed refrigerating system.
Be careful when servicing the refrigeration circuit. On contact with the air, the
pressurized refrigerant evaporates and it immediately frostbites whatever is in
close contact with it. Should this gas come into contact with the body, below are
some first aid measures:
1. Cover the affected area.
2. Quickly heat the frostbitten area with lukewarm water. AVOID USING HOT
WATER.
3. If there is no water available, wrap up the affected area carefully with a clean
cloth.
4. If the gas comes into contact with the eyes, rinse them immediately with run-
ning water and call an ophthalmologist.

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.
Only by having the unit checked on a regular basis you will be able to avoid the
troubles associated with its malfunctioning.
Warranty
Keep your warranty certificate carefully; you will be required to show it whenev-
er your refrigeration unit needs servicing.
The machine should be installed according to the diagrams and instructions
given by the manufacturer.
Any damage due to improper connections is excluded from the warranty.
The neutral conductor, even if grounded, is unacceptable as safety conductor.
The electrical installation of the place where the unit is installed must comply with
the regulations in force applicable to electrical installations.
The machine must be used according to the user's instructions and only for the
use the manufacturer intended it for.
The machine should be serviced by knowledgeable personnel or by the manu-
facturer.
51
When ordering spare parts, always include the serial number shown on the
machine's rating plate.
Disposing of the packing
Dispose of all wooden, plastic and polystyrene packing in compliance with the
laws in force in the Country where the equipment is used.
Disposing of the machine
Should the machine be scrapped, its components must not be scattered in the
environment. They are to be disposed of through a company authorized to col-
lect and recycle special waste, in compliance with the laws in force in the Country
where the machine is used.
In particular, the refrigerant must absolutely be reclaimed and disposed of by a
company authorized to collect special waste.
