INTRODUCTION TO MACHINE OPERATION
OPERA TING CYCLE DESCRIPTION
Correctly connect the ice maker to power and water mains, fill up the water tank and bring the machine
switch to position “I”. Power will get to the compressor, water pump and fan motors, switching them on to
start the freezing cycle. The nozzles will begin spraying water into the caps.
As the evaporator thermostat bulb reaches the right temperature, the freezing cycle timer starts off.
At the set time, the water pump stops and the water load (to top up the tank) and cycle reversal solenoid
valves are opened. Heat is pumped to the evaporator and, as a result, the ice cubes are dropped from the
copper caps into the ice storage bin. When the bin is full, the ice level thermostat stops ice production.
As the evaporator thermostat reaches the preset temperature, the cycle reversal timer starts off. At the set
time, the water load and cycle reversal solenoid valves are closed and the machine starts a new freezing
cycle.
