Operation
indicates that the unit is in the regular (middle) setting of the ice size.
• When the machine is in the cleaning stage or ice full stage, the ice size adjustment mode cannot be
accessed.
During the ice-making stage, the hot gas solenoid valve is closed. The hot refrigerant gas is pumped out off
the compressor to the condenser. The hot gas is cooled by fan forced air to the warm liquid refrigerant after
passing through the condenser. The drier & filter reduces the possible dirt and humidity in the refrigerant. The
evaporator is cooled by the refrigerant. Some ice can be formed on the evaporator during the water spraying
process in the evaporator. Low pressure refrigerant gas may go back to the compressor from the evaporator.
During the ice harvest stage, the solenoid valve is opened. The hot refrigerant gas is pumped out off the
compressor to the evaporator through the hot gas valve. As the hot gas is not cooled by the condenser, the
refrigerant makes the evaporator (ice mold) slightly warm. So some ice touching the evaporator is thawed. All
of ice can slide down to the ice storage bin.

WATER SYSTEM

When the water supply pipe is connected with the main water supply, water will fill the water trough through the
floater valve until enough water inside water trough makes floater valve close. During the ice-making stage,
water is pumped from the water trough to the water distribution tube. The distributed water flows to the surface
of the evaporator. Most parts of water go back to the water trough. Some water is frozen on the evaporator
step by step. The floater valve will open and fresh water is

CIRCUIT DESCRIPTION

First time usage: As the icemaker is properly installed, switch on the water tap, let the water trough fill
(reach full on the level), then press the ON/OFF button on the front panel. The icemaker will start working
automatically In this status, the time is fixed to about 3 minutes. This function is also helpful to protect the
compressor from avoiding restart within 3 minutes. At this status, the Red, Green, Yellow LEDs are lit together.
Ice-making status: The compressor, motor fan and pump are powered on. The hot gas solenoid valve is
powered off. When this green LED is lit, the unit is working in the ice making mode controlled by a temperature
probe on the evaporator. When the green LED is flashing, the unit is working in the ice making mode controlled
by a fixed timer. The fan motor is also controlled by a condenser sensor. When the ambient temperature is too
low, the motor fan will stop working for good condensation to the refrigerant.
Ice harvest status: The pump is powered off. The hot gas solenoid valve, compressor and motor fan is
powered on. The fan motor is also controlled by a condenser sensor. When the ambient temperature is too
low, the motor fan will stop working for good condensation to the refrigerant. The Yellow LED indicates the ice
harvest status.
Ice full status: If the ice bin is filled with ice or the full sensor is covered, the machine stops making ice
automatically. In this status, the compressor stops working. The RED LED indicates the ice full status.
