Thank you for choosing Uniblock. Please read these instructions carefully. They provide details and advice
on the correct method of installing, using and maintaining this unit, in order to obtain maximum reliability,
efficiency and long life.

1. Safety recommendations

When installing and using the unit please follow the recommendations listed here below.

• Installation shall be carried out in strict compliance with the diagrams and instructions supplied by the

manufacturer.

• Damages due to improper connections are excluded.

• The electric system available where the unit is installed shall meet the relevant standards in force.

• Maintenance shall be effected by trained personnel or by the manufacturer according to the provisions

supplied by EN378.

WARNING
Use safety gloves to protect your hands from possible cuts.

The user is strongly recommended to contact the manufacturer before attempting any intervention on the unit and
any use not corresponding to the manufacturer’s indications (in particular as for the field of application) and to
enquire about the possible dangers and contra-indications connected with an improper use of the machine.

• The unit shall be used following these instructions and sticking to the destination of use indicated by the

supplier. Any incorrect use can result in damages to the unit and represents a serious danger for people’s
health.

ATTENTION
The unit is not suitable for working in explosive environments.
Therefore the use of the unit in an explosion-dangerous atmosphere is absolutely
forbidden.

ATTENTION
The unit is not suitable for working in salty environments. In such a case protect
condenser and evaporator with appropriate means.

When maintenance involves operations on the refrigerating circuit, empty the system and let it reach the
atmospheric pressure.

WARNING
Do not discharge the refrigerant in the atmosphere. It must be recovered by specialized
technicians using suitable equipment.

• Quantity and quality of the refrigerant to be charged are indicated on the data plate.

• Do not use refrigerants of different kind (especially inflammable fluids, for example hydrocarbons) or air.

• Do not modify or alter the refrigerating circuit or its components (for example: welding on compressor

body)

• The final user shall protect the system from external fire dangers.

• The unit has been designed to ensure a constant temperature control during transport. The cold storage

room must be well insulated, provided with airtight door and optimal ventilation.

If the temperature of the product loaded is too high, the unit will not be able to cool it down.

46

For safe use of the unit, we suggest:

ATTENTION

• Do not use water or steam when cleaning as the electrical components may be damaged.

• Keep condenser and evaporator clean.

• Stand-by operation in enclosed places: ensure good ventilation to the condenser.

• Check that all screws are properly fixed and suitable to the purpose.

• When making holes in the unit or in the vehicle chassis, take care not to pierce the refrigerating pipings,

the electrical wiring or any other vehicle component.

• Never close the compressor discharge valve when the unit is working.

• When working on the unit, use only flexible pipes of gauges in good conditions and avoid touching belts,

pulley or fan.

WARNING

• Cleaning and maintenance are to be carried out with the unit switched OFF.

• After a running period, condenser and H/P discharge pipes are very hot; let them cool down before

carrying out any operation.

• Handle fans, belts and pulleys carefully, with the unit OFF: prevent them from unexpected starting.

• When working near the coils (condenser and evaporator), pay attention not to cut oneself with the edges

of the fins.

• When the unit is working, avoid putting hands near fans and belts.

• Refrigerant fluid handling has to be carried out taking all necessary precautions.

• Near a heating source refrigerant fluid produces an unpleasant smelling gas, irritating for the respiratory

system.

• Never heat with fire a cooling cylinder containing refrigerant fluid.

• For any kind of manipulation on the unit, take all possible precautions

• Refrigerant in liquid state evaporates in contact with the atmosphere and freezes everything it touches.

• First aid in case of freezing:

a) Cover the frozen part.
b) Immediately warm the frozen part by dipping into cold water.
c) If water is not available or impossible to use, gently wrap up the frozen part in a clean cloth.
d) If some refrigerant fluid sprinkles on the eyes, immediately rinse with clean water; as a precaution

consult a doctor.

e) call a doctor

• Refrigerant oil.
Synthetic types.
Avoid prolonged or repeated contact with skin.
Wash hands thoroughly after handling.

The unit starts automatically; keep away from moving components (belts, pulleys, fans).

47

1.1 Warranty

It is possible that certain options do not appear on the warranty, in this case contact our assistance
service. The chiller structure must be evaluated by the manufacturer in order to determine its capacity to support
the additional loads imposed by unit installation. These indications do not constitute an approval or a warranty on
the part of ZANOTTI S.p.A. regarding the integrity of the chiller. It may happen that some of the adaptable
elements described in the installation procedure do not correspond. If this should occur, contact our service office.
In order to improve the quality of our products, ZANOTTI S.p.A. reserves the right to modify them without
notice.

1.2 Maintenance

For the safety and upkeep of the refrigeration unit it is important that maintenance work is carried out following
the timing indicated by the manufacturer (see maintenance table).
Maintenance work, as well as repairs, must be carried out by ZANOTTI S.p.A. authorized repair shops.

1.3 Safety information
WARNING

• If using the refrigeration unit in a closed environment, use only the "MAINS" function (keep the vehicle motor

strictly turned off in order to avoid discharged gas poisoning).

• Ensure that there is a distance of at least 60 cm between the condenser and the ceiling, and adequate

external air circulation.

• Cleaning operations on the refrigeration unit are carried out with the system turned off and after waiting for

this to cool.

• To clean, use a cloth dampened with detergent.

• Do not use jets of water or steam under pressure as this could damage the system electrical parts.

MOVING PARTS

• As a rule, do not carry out maintenance work while the refrigeration system is in motion, and take all

precautions to avoid unwanted start-ups.

• · During maintenance or repair operations, pay attention to moving parts such as fans, belts and pulleys.

HOT SURFACES

• Do not use the refrigeration unit with fairing or panels open or dismantled.

• Do not obstruct condensation airflow in any way.

• At the end of each operation period, the compressor, the condenser and the high pressure piping will be very

hot. Avoid therefore any form of direct contact with these components during checking or repair stages until
they have cooled down.

• Check regularly that dust, detritus or foreign bodies do not block the air circulation around the radiator core of

the condenser and evaporator.

48

• If necessary, clean the parts in question.

• Do not let children operate the refrigeration system.

ELECTRIC SHOCKS

• Before opening the electric control box door, make sure that the power is turned off.

• Before carrying out any soldering work on the refrigeration system, disconnect the vehicle battery.

• Before carrying out soldering on the bodywork, ensure that the unit and vehicle batteries are disconnected, as

are the charge and three-phase alternators.

• Ensure that the electrical feed system has a ground connection device.

• Electrical systems in a residence or workshop must be connected to the refrigeration unit professionally by

expert staff.

BATTERY MAINTENANCE

• Check the electrolyte level of the vehicle battery regularly. If necessary, add distilled water.

• If the battery is run-down, recharge it and, if it is dead, check that the power is adequate for the use required

of it.

• Never start up your unit or vehicle with the help of a fast loader, so as not to risk damaging the electronic

system of the unit or vehicle.
