5.2 DEFROSTING

The ice on the battery must be removed regularly, therefore after about 14 hours of operating, the timer (25)

switches from contact 3-4 to contact 3-2, disconnecting the compressor and the fan and switching on the stylus

defrosting heater (9) and armoured (9a).

For safety reasons and rules in the evaporator battery there are two defrosting heaters that are simultaneously

powered, since they are connected in parallel.

After 36 minutes defrosting, the timer switches to contact 3-4 again, switching on the compressor and the fan

and disconnecting the heating elements.

If the battery temperature reaches +10°C in less than 36 minutes, the heaters are switched off by the defrosting

cut-out switch (26). If, for any reason, it does not switch on and the battery temperature reaches +40°C the

heating elements will be switched off by the safety thermal switch (27).

The arrows in the picture show the current path.
