Evaporator
Fig. 04
The machine carries out defrosting cycles to prevent ice from building up in the
evaporator of the cooling unit, which would have adverse effects on the unit’s
performance. The defrosting cycle consists of turning the cooling unit off long enough for
the ice build-up on the evaporator to disappear. A total of 3 defrosting cycles are carried
out a day at approximately 8-hour intervals. The unit is further defrosted three hours after
the machine has been restocked with product; in this case the internal temperature will
not be shown on the display until one hour after the defrosting cycle began.
There is a window to permit air circulation
through the inside area where the compressor
and condenser are located. It is located at the
back of the machine cabinet. For proper
operation of the cooling system the window
should be kept free of dust and you should
check regularly that it is not obstructed by
foreign objects, such as bags, papers, etc.
The indoor temperature can be programmed
in the MASTER level machine option between
0.5 °C (32.9 °F) and 12 °C (53.6 °F).
Note:
For safety reasons, every time the unit is stopped and started, the
process is detained during a 4-minute interval.

check the pressure of the cooling unit,
remove the black cap, where the head
of the core is located. Connecting a
pressure gauge and get a pressure
reading.
