B.The fan motor for condenser is controlled by temperature, when condenser’s
surface temperature is lower, the fan motor will stop, so as to save power; when
surface temperature rises up, the fan motor will work again, so fan motor work
intermittently during the ice-make process.
C.When a commercial ice maker works at a lower ambient temperature, the
ice-drop process will be later than usual. If it occurs three times continuously, the
machine will stop automatically, and the red light in the electrical box alternately
flickers with the other four lights. After restarting the machine, it will become
normal. Therefore, we suggest the user not use the machine at a low ambient
temperature.

SERVICE INSTRUCTION
1.Operation process
First, turn on the water faucet, power, and water supply valve, then fill the sink with
water, and turn off the faucet when the sink is filled with appropriate water.
2. Ice-make process
After several minutes, the water pump starts work, and the water will be pumped
and flowed through the ice model evenly. At last, the ice is formed in the model.
When the ice thickness sensor detects the regulated thickness of ice, the ice starts
to drop.
3. Ice-drop process
The water pump stops working, the water supply valve will be opened, and water
go into the sink. The heating valve will be turned on, and the refrigerant gas is led
into the ice model; the ice root will be melted, and after about 2 minutes, the ice
block drop into the ice cabinet. The falling ice block hit the retaining board (the
inductive switch, which is fixed on the right side of the retaining board, till now, one
circle is over, and the new ice-make circle will start.
4. Auto-stop
When the ice cabinet is filled with ice blocks, the continuing falling ice block will be
locked between the retained board and evaporator; the retained board would be
opened continually and couldn’t return to the original position. After several
seconds, the ice maker will stop working automatically. Once the ice block locked
between the retained board and evaporator is taken away, the retained board will
return to the its original position, and the ice maker will restart to make ice.
5. Running check
A.When the ice maker is in the working process, a sudden interruption of water
supply can lead to the sink not being filled with appropriate water. The ice maker
will turn into standby condition and not make ice as usual. After the water supply
becomes normal and restart the machine, it can work normally.

Environment humidity: relative humidity ≤90%
Ice maker accessories
The distance between the air outlets and the wall should be over 30 cm. Besides,
keep good ventilation and ensure the machine is dry and clean. The position to
place the ice maker must be far away from the heat source, such as a bake
oven,electric cooker, etc.
B. Water source is suitable for the sanitary standards, the water temperature
and pressure is suitable. For getting the biggest efficiency, the inlet water
temperature value should be 0.6~32℃, and the pressure should be
0.138~0.552MPa.
C. There should be a sewer. While working, some of the water will be
- 8 -
discharged, so the sewer is necessary. Furthermore, the sewer must be kept
unblocked.
POWER SUPPLY
1.Select the proper power supply according to the voltage and power on the
nameplate.
2.Connect the power wire and supply, ensuring the yellow and green wires were
connected with the ground wire firmly.
Caution:
a.For safety, ensure the ground connection is in good condition.
b.All the exterior wires and other appliances must confirm with
national standard.
3.If the voltage fluctuation range is extensive (± 10% over the rated voltage), it will
cause many faults, such as the machine can’t be started, the electronic control
board is damaged, or the compressor being damaged. Therefore, you must use a
suitable automatic voltage regulator.

4. Connect the water supply pipe
Take out the water supply pipe from accessory bag, connect pipe’s double ends to
the water supply valve and water faucet. First, sleeve the connector 1 to the water
faucet, then join one end of water supply pipe which has steel balls to the
connector 1(hang on this water supply pipe’s end, loose it after being connected to
the connector 1), and connect the other end which is attached with a screw to the
water supply valve, the valve also has a screw in its end, screw down the valve in
clockwise. Once finished installation, check the connect part if it is leaks or not.
you should connect the water pipes according to the diagram on the rear panel.
The flow rate of condensate water is adjustable according to customers’ need.
(Condensate flow relates to the speed of making ice)
Warning：The water used to make edible ice block must be
drinking water, furthermore, water’s temperature must be
among 0.6~32℃ and the pressure among 0.138~0.552Mpa.
5. Connect the water discharge pipe
The water discharge pipe is situated at the back of the machine, extended pipe’s
end to the sewer.
Attention
：
In order to keep the water discharged smoothly,
discharge pipe’s lowest point must be above the highest point of
the sewer, so to prevent the discharge water to flow back.
6. Keep the main body in level situation
Please keep the main body level to ensure the ice maker
usually works. First, screw down the two adjustable legs into
the machine’s nuts. You can adjust the two legs properly if the
main body is not level.
