6. Check the water connections and effi-
ciency of the pressure switch valve dur-
ing operation, as well as the flow of con-
densing water (in water-cooled units).
7. Perform at least one blast freezing cycle
(to the SET temperature) and one manu-
al defrosting cycle.

2.8 Safety and control systems
• Door microswitch: shuts down fan opera-
tion in the cell when the door is opened.
• General fuses: protect the power circuit
against short circuiting and overloads.
• Compressor heat relay: intervenes in the
event of overloads or operating faults.
• Safety pressure switch: intervenes in the
event of excessive pressure in the refrig-
erant circuit.
• Plug fuses: intervene in the event of over-
pressure or operating fault in the safety
pressure switch (see above).
• Chamber temperature control: operated
by the electronic board by means of a
probe inside the cell.
• Temperature control end defrost cycle:
controlled by the electronic board by
means of the probe in the evaporator.
2.9 Appliance disposal
Demolish and dispose of the machine in
compliance with the regulations applied in
