h. Condenser Air Filter
Located in front of the air condenser, it can be removed by withdrawing it through
the opening of the front panel for cleaning or replacing.
i. Water Spray System
Water is pumped and sprayed (through the nozzles) into each individual cup to be
frozen into ice. It consists of one spray tube and several spray nozzles.
j. Water Inlet Solenoid Valve
The water inlet solenoid valve is activated by the microprocessor of the PC Board
during the first 5 minutes of the water filling phase as well as during the defrost cycle.
When energized, it allows a metered amount of incoming water to flow over the
evaporator cavity to assist the hot gas in defrosting the ice cubes. The water running
over the evaporator cavity drops by gravity, through the dribble holes of the plate,
into the sump reservoir, where it will be pumped by the water pump to prime the
spray system.
k. Hot Gas Solenoid Valve
The hot gas solenoid valve consists basically in two parts: the valve body ad the valve
coil. Located on the hot gas line, this valve is energized through the microprocessor
of the PC Board during the defrost cycle as well as during the water filling phase.
During the defrost cycle, the hot gas valve coil is activated to attract the hot gas valve
piston in order to give way to the hot gas discharged from the compressor to flow
directly into the evaporator serpentine to defrost the formed ice cubes.
l. Fan Motor
The fan motor is controlled through the PC Board and the TRIAC by the condenser
temperature sensor. Normally, it operates only during the freeze cycle to draw
cooling air through the condenser fins. In the second part of the freeze cycle, the fan
motor can run intermittently as the condenser pressure must be kept between two
corresponding head pressure values.
m. Compressor
The hermetic compressor is the heart of the refrigerant system and is used to
circulate and retrieve the refrigerant throughout the entire system. It compresses
