Technical Information
•
Check the efficient insulation of the connecting pipes
between the condenser and the remote condensing
unit.
•
Check the electrical connection
•
Check the electrical input
•
Verify the standard pressures of the refrigerating system
•
Check the water connections with adjustment of the
pressure valve during operation and good circulation of
the condensation water (water cooled groups).
3.10 - Commissioning
Commissioning must be carried out by
,
authorised and qualified personnel.
Perform at least one complete cycle of rapid storage
freezing (to reach the SET temperature), and a manual
defrost cycle. If the equipment or the remote condensing
units were delivered in an upright position (e.g. on their
back) or were overturned during installation, do not turn
on immediately but wait at least 4 hours before use.
Inform the customer of the exact use of the equipment
with specific reference to the use and to customer
requirements.
3.11 - Safety and control systems
•
Door microswitch: this locks operation of the fans in the
cell when the door is opened.
•
General protection fuses: they protect the entire power
circuit against short circuits and possible overloads.
•
Compressor thermal relay: this intervenes in case of
overloads or malfunction.
•
Safety pressure switch: this operates in the case of
excess pressure in the refrigerant circuit.
•
Fusible plug: this intervenes in the case of overpressure
and failure of the afore-mentioned safety pressure
switch.
•
Chamber temperature control: this is operated by the
electronic card via the probe positioned inside the cell.
•
Defrost termination temperature control: this is
managed by the electronic card via the probe located
on the evaporator.
3.12 - Stop modes
In an emergency, to stop the machine remove power from
the main panel using the earthing switch or by removing
the plug from the socket making sure hands are not wet or
damp.

Dismantled (with condesnsing units/remote
condensors)
You are requested to communicate to the retailer/service
center the machine model and the code shown on the
registration plate located above the control panel.
