5.3 Commissioning In order to achieve optimum performance, the unit must be:
a) Place the cell in a well ventilated room, away from heat sources .
b) Check that the unit has adequate aspirating and extracting power.
5.4 Area surrounding the unit In order to allow it to work properly and to facilitate its maintenance in safety con-
ditions, the unit should be installed providing the minimum spatial requirements
for opening the unit, indicated in figs 6-7.
Ensure that no damage has occurred to the unit or the equipment it contains during
transportation, particularly to the components fixed to the electric control panel door
and to the refrigerating system pipes. To install the unit, proceed as indicated in the
diagrams, taking special care to level the unit.
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 differential.
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 ,
And of the short circuit current present at the installation point.
When a cell contains more than one unit, each should be fitted with its own
magnetothermal switch differential.
Now connect the unit paying attention to the colour of the wires that make up the
power supply cable:
a) 110V-230V/1~/50-60 Hz 3 wires Blue = neutral
Yellow/Green = earth
Brown = phase
b) 230V/3~/50-60 Hz 4 wires Blue = phase
Yellow/green = earth
Brown = phase
Black = phase
c) 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.
It is It is obligatory to follow correct phase sequencing in order to have correct
compressor rotation. If phase sequencing is incorrect then an electronic device in
the electrical panel - or integrated in the compressor protection module - will pre-
vent the compressor from starting.

high pressure switch 28 bar working with R404A
To start the machine up proceed as follows:
A) Set the control thermostat supplied by others (usually fitted on the evaporator)
to the required temperature in the cold room or cabinet. The thermostat can be
wired as per the schematic or can act directly on the liquid line solenoid valve.
B) Select 'preheating' position on the PREHEATING/STOP/RUN switch supplied
by others. Method of connection is shown in the schematic.
C) Turn the mains isolator switch to ON
Leave the unit in preheating mode for at least 4 hours in mild climates and longer
( at least 12 hours ) in cold climates. This should be repeated every time the unit
has been switched OFF for more than 24 hours. When shutting down the unit
during normal operation always leave in preheating mode.
D) Having completed the preheating phase, turn the PREHEATING/STOP/RUN
switch to the 'RUN' position.
E) If the compressor does not start check:-
- if there is mains voltage to the unit
- if the correct phase sequence has been made
Low pressure trip indicates low refrigerant charge. Check for leaks and having
repaired them, recharge the system and restart the commissioning as above.
Auxiliary fuse trip. Find and remove cause of trip.

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 front 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 effectively 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 unit has stopped working (the indicator light on the panel is
on) it is necessary to reset the thermal relay manually, having first identified the
causes of the malfunction.
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 devi-
ce is designed to safeguard electrical fans against excessive current absorption due to:
- overheating
- lack of one phase (only for three phase models)
- dirt in the condenser
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
It is generally used to stop the unit working in pump-down mode.
The triggering of the pressure switch can also indicate excessively low pressure

in relation to the set points, due to one of the following causes:
- 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 - automatic resetting
These are inserted in the compressor’s coil to protect the motor from overheating
(see electrical diagram)
e) Discharge Line Thermostat
Protects the compressor from elevated discharge temperatures which can occur
in certain conditions such as low gas charge or failed condenser fan.
f) Phase sequencing relay
Is an electronic device which prevents the compressor from starting if the phases
are not connected in the correct sequence. This device can be found either in the
electrical panel or integrated in the compressor protection module.
g) Minimum and maximum tension electronic relay (Monitor) - automatic
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 minu-
tes, 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)
h) Condenser fans variable speed drive
Electronic system for checking the speed of condenser fans.
In case of system malfunction:
- turn off at mains
- open the electric control panel
- the variable speed drive is located inside the control panel.
Move the switch to position (1)
- close the electric control panel and reset the unit
- replace the variable speed drive as soon as possible
- having replaced it, move the variable speed drive to the automatic
position (0).
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.
