3.9 Notes for the installer

• Verify the correct installation and system testing before
starting up the machine (test report)
• Check for any gas leaks from the welds or joints made
during the installation phase.
• 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 sys-
tem.
• 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

I
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 de-
livered 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 malfunctions
• 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 man-
aged 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
10
or damp.

3.13 Signalling/reports of malfunctioning
