6.1 Cleaning the unit Carefully clean the unit with detergents or degreasing substances, removing dust, dirt
and any foreign matter that may have deposited on it during transportation.
CAUTION! Do not use solvents
6.2 Connecting the unit to external 6.2.1 Power mains connection
energy sources Before making the electrical connection, ensure that the voltage and frequency of
the mains supply are as indicated on the unit’s serial plate and that the power
supply is within +/- 10% of nominal value
Having conducted a preliminary inspection of the elements of the panel, make the
electrical connection. Connection to the mains supply must be made through a
magnetothermal or fused switch.
Safety devices (magnetothermal and/or fused switches ) should be installed on the
power supply line taking into account the current absorption indicated on the plate.
For instance:
Current absorption indicated on the plate:
Operating current 12KW - 28,5 A
Maximum current 40 A
Starting absorption 134A
In this case, a 40A magnetothermal switch with a “C” curve (CEI 23.3 IV -EN 60-
898) should be installed. Alternatively, an appropriately sized fused switch should
be used for the maximum 40A current, which should also be capable of withstan-
ding a 134A starting current without being tripped. The system must be fitted with
an adequate equipotential safety circuit (earth connection).
It is also advisable to install a differential switch at source.
Follow the diagram below to make the electrical connection correctly for CU-O :

When a cell contains more than one unit, each should be fitted with its own
magnetothermal switch.
Now connect the unit paying attention to the colour of the wires that make up the
power supply cable:
a) 230V/3~/50-60 Hz 4 wires Blue = phase
Yellow/green = earth
Brown = phase
Black = phase
b) 400V/3N~/50-60 Hz 5 wires Blue = neutral
Yellow/Green = earth
Brown = phase
Black = phase
Black = phase
N.B.: All units are supplied with terminals 3-4 to which it is possible to connect
any device not alive; for example an ambient thermostat.
CAUTION
Magnetothermal safety switches should be used to protect the main power sup-
ply line from power surges.
Only qualified personnel is authorised to replace the safety thermal relays fitted
on motors.
Only qualified personnel must be authorised to make electrical connections.
6.2.2 Connection to the water mains (water condenser)
The water condenser must be connected to the water mains following the indications
on the plates next to the tubes, which are marked IN (ENTRATA) and OUT (USCI-
TA). The diameter of the pipes used to make the connection must not be smaller
than the unit’s outlet tubes. Pressure in the water circuit must be at least 1 bar.
6.3 Checks, adjustments and settings Before switching the machine on, ensure that:
- locking screws are fixed tight
- electrical connections have been made correctly
When the unit is opened, check that:
- no tools have been left inside
- assembly has been correctly performed
- there are no gas leaks
- panels have been correctly fixed.
6.4 Setting of the control and During the testing on make the setting of these devices. Below we list the rated
power devices values of the pressure switches settings; these values must be considered

To start the machine up proceed as follows:
A) Adjust the ambient thermostat, which is on the evaporator, to the desired tempera-
ture inside the refrigerating cell. Units with remote control panels are equipped with
an electronic room thermostat which is located on the remote control panel itself.
The thermostat can be connected following the scheme; or it can work on the sole-
noid valve which pipes the refrigerant to the evaporator.
B) Position the switch preheating/stop/running, arranged by the customer, on
preheating (the indication for the connection is in the electric scheme).
C) Move the mains switch to position (ON). Leave the unit in the pre-start position
for at least 4 hours. If the temperature is particularly cold, keep the unit in the
pre-start position for at least 12 hours.
D) At the end of the pre-start phase, move the pre-start/stop/start switch to opera-
ting position.
E) If the compressor fails to start, check:
- connection to the power supply
- a blockage in the minimum pressure switch due to the lack of refrigera-
ting gas. In this case the leak must be identified and repaired before
refilling the compressor and proceeding again with the operations
illustrated above.
- Faulty auxiliary fuse = identify and eliminate the cause.
7.1 Electrical controls 7.1.1 Control panel
The CU-O units use only one model of control panel. (fig.9)
8.1 Description of the unit Uniblock CU refrigerating units operate through a sealed or semi-sealed refrige-
working cycle rating compressor, powered by mains a/c supply (three phase) and use HFC

Adequate maintenance is an important factor to ensure the long life and optimum
performance of the unit and the safety conditions required by the Manufacturer.
9.1 General maintenance It is essential to clean the condenser which is located in the lower part of the
compressor unit (externally to the cell) in an easily accessible position.
The condenser is used to cool the refrigerating gas and it will work more effecti-
vely if it is kept free of dust.
The unit can be cleaned by simply using a dry brush and reaching deep between
the condenser’s fins or, better still, by using an air jet and blowing from the inside
out. This operation must be carried out while the unit is switched off.
If there are traces of oil on the condenser, check where they come from and,
having repaired the leak, clean using a detergent such as alcohol or petrol.
WARNING: To avoid cutting your hands, use protective gloves.
9.2 Special maintenance operations Periodically check the wear of electrical contacts and remote control switches
and replace if necessary.
9.3 Operations to be carried out Below is a list of maintenance operations that require specific technical compe-
by qualified personnel or by tencies and must therefore be carried out by qualified personnel or by the
the Manufacturer Manufacturer.
The User must on no account:
- replace electrical components
- tamper with the electric system
- make repairs on mechanical parts
- tamper with the refrigerating system
- tamper with the control panel
- tamper with safety and protection devices
9.4 Troubleshooting guide Technical problems that may occur during the operation of the machine:
1. In case of malfunction of the system, check the refrigerating gas through the flow
indicator located on all units (this must be checked when the unit is operating and the
cell temperature is close to the required temperature). Normally the indicator is clear,
while, in the absence of gas, gas bubbles will appear.
2. If the compressor or fan stop, check the following:
- whether the safety fuses of the main and auxiliary circuit have been blown, in
which case they should be replaced, after checking the suitability of the mains
tension and ensuring that phase polarity is correct.
- if the compressor has blocked, it is necessary to wait for the automatic resetting
of the internal protention.
- if the fan is blocked, it will automatically reactivate, never the less it is necessary
to look for the cause of the blocking.
WARNING:
It absolutely forbidden to remove the safety devices provided by the anufacturer
to protect operators while the machine is in operation.
3. Other malfunctions may be due to the triggering of the following electrical
safety devices:
a) Fan thermal protection (incorporated in the motor) - automatic resetting. This
device is designed to safeguard electrical fans against excessive current absorp-
tion due to:
- overheating
- lack of one phase (only for three phase models)
- dirt in the condenser
9. MAINTENANCE AND REPAIRS

b) High pressure switch - manual resetting
It is designed to protect the compressor from excessive pressure, which cause
the pressure switch to be triggered too often, deriving from:
- dirt in the condenser
- condenser fans not working
- excessive temperature in the room where the system is located
- use of the system in unsuitable conditions or with inappropriate products.
To reset press the button on the pressure switch.
c) Low pressure switch - automatic resetting.
If the thermostat, arranged by the customer, works on the solenoid valve which
pipes the refrigerant to the evaporator, the unit will stop at every closure of the
solenoid valve, through the switch L/P (pump down). The intervention of the air
pressure switch can be caused even by some anomalies as:
- lack of gas due to the breakage of a pipe or to loose hub
- clogged up filters
- solenoid valve failure
- ice in the evaporator
The minimum and maximum temperature pressure switches and the oil pressure
switch are located inside the motor casing. Before resetting, disconnect from mains.
d) Thermistors or thermostats - automatic resetting
These are inserted in the compressor’s coil to protect the motor from overheating
(see electrical diagram)
e) Minimum and maximum tension electronic relay (Monitor)optional - auto-
matic reset (where applicable). It is used to protect the unit against anomalies in
the power supply (+/-12% of nominal value). The unit starts with a delay of 8
minutes, indicated on the panel by a LED.
The main factors that cause the triggering of the device are anomalies in the
power supply (for further information see attachment)
f) Condenser fan pressure switch
it is designed to control the condensing temperature.
In case of failure it can determine the activation of the h.p. pressure switch.
9.5 Parts subject to wear and spares Only qualified personnel or the Manufacturer are authorised to replace worn
parts.
Materials such as wood, plastics, polystyrene are used in packing and must be
disposed of in compliance with local legislation.
When, for whatever reason, the owner wishes to dispose of the machine and
dismantle it, it is necessary to follow some fundamental rules for protecting
human health and the environment in which we live.
Conduits, flexible tubes, plastic or non-metallic components must be disassem-
bled and disposed of separately.
Electrical components such as switches, transformers, etc. must be disassem-
bled in order to be reused if they are still in good condition, or to be reconditioned
and recycled where possible.
Pneumatic and electrical components such as valves, electrical valves, pressure
regulators must be disassembled in order to be reused if they are still in good
condition, or to be reconditioned and recycled where possible.
The refrigerating liquid must be drained completely and disposed of by specialists.
The casing and all metal parts of the unit should be disassembled and different
materials should be separately grouped. The various parts thus obtained will thus
