COOLING SYSTEM
The cooling unit is mounted onto the base.
The cooling temperature, between 0° C and 3° C, is preset
by the manufacturer.
MAINTENANCE AND CLEANING
The machine must be kept clean at all times, both inside
and outside.
Normally available products, as long as they are mild, may
be used for cleaning.
When cleaning the drum halves in a dish washer, the
water temperature should never exceed 60° C.
Any detergent residue can cause unpleasant odour
inside the machine!
To ensure perfect operation, the product slider guides
should always be kept clean.
Never use grease or oil!
IMPORTANT NOTICE
The drums must never come into contact with grease or
oil!
The condenser must be kept clean using a vacuum
cleaner, a brush etc.
POWER SUPPLY UNIT
The fuses, switches and connectors which are on the front
of the power supply unit have the functions indicated
below.
When the protective casing is fitted, only the fuses and the
main switch are accessible.
When replacing any fuses the machine must be dis-
connected from the power supply.

AUTOMATIC DEFROSTING DEVICE
Automatic defrosting is enabled through programming.
The defrosting system operation, indicated in Fig. 19, is as
follows:
The bypass solenoid valve stays open until the sensor on
the evaporator detects a temperature of 4° C.
However, the software ensures that the defrosting cycle
does not exceed 10 minutes.
The hot gas produced by the compressor flows directly to
the evaporator through the bypass pipe.
With the bypass solenoid valve open the evaporator fans
are stopped, to avoid a temperature increase inside the
refrigerated box.
