and water supply, and start
making ice.
3. The ice maker is surrounded
by ventilation channels, and it
is forbidden to block it by
excess items.

to freeze or freeze any food in the refrigerator, to keep the
ice shovel clean.
·When closing the plastic door of the refrigerator, open or
close it gently, and do not hit the door, and please also
close the sliding door after taking the ice out.
·The ice maker should be kept away from heat sources,
strictly forbidden to use it in high or low temperature
environment. Away from direct sunlight to avoid affecting
the heat dissipation of the appliance.
·Do not wash the ice maker surfaces with water directly,
which may cause short circuit and leakage.
·If the ice maker is suspended for a long time after using it

environments;
·Farm houses and by clients in hotels, motels and other
residential type environment;
·Family hotel environment;
·Catering and similar non-retail applications.

·Installation location requestment
Transporting and moving conditions:
When transporting, keep the tank as upright as possible,
and the inclination does not exceed 45 °maximum. Do not
locate it upside down or horizontally. To operate the ice
maker properly and get the best performance, please
locate the ice maker as the following conditions.
1.Level & flat floor: Put the ice maker on a level & flat floor,
to avoid excessive vibration and noise.
2.Keep away from heat resource: Avoid locating the ice
maker near hot equipment, such as gas stoves or stoves.
The ice making performance will decrease when the ice
maker is heated.
3.Avoid direct sunlight: If the ice maker is located in direct
sunlight, it may cause abnormal performance and may
shorten its working life.
4.Dry area: Avoid locating the ice maker in a wet area,
such as near a faucet or a sink.

WARNING：
Make sure to use a plug with a grounding structure and
ground the ice maker, to prevent electric shock in the event
of a leakage.
Replacing the ground terminal with a water pipe will not
provide effective ground protection in many situations,
because plastic pipes are often used as water pipes.
Do not ground the ice machine through a gas pipe, very
dangerous.
Do not ground the ice machine through a telephone line or
lightning protection, because lightning strike will create
generate large currents, very dangerous.
Install a disconnect switch: If locate the ice maker in a
wet area, a disconnect switch must be installed and the ice
maker must be earthed. Install the disconnect switch in the
power circuit. For further information, please consult the
ice maker retailer or electrical technician.

·Installation & Location
Base installation:
1. Locate the ice maker in a level & flat fllor.
2. Adjust the height of the feet to make the ice maker level.
3. The ice maker is not suitable for outdoor use. The
normal use environment temperature is 10℃～32℃, and
the water temperature is 5℃～30℃. High temperature will
seriously decrease the ice making performance.
4.The ice maker should not be installed in an environment
where there is no sewer and water is not allowed, and it
should be away from high temperature equipment (such as

refrigerators or ovens).
5.Air-cooled ice makers rely on air circulation to dissipate
heat. Therefore, it need at least 15cm of space between
the front, back, left, and right of your ice maker and wall,
good for heat dissipation.
Water Connection：
1. The ice maker must use room temperature filtered
drinking water.
2. The water pressure of the water supply must be
controlled between 100kpa and 800kpa. A pressure relief
valve is required for overpressure. Do not squeeze the
water inlet hose.
3. At the same time of feeding the tap water, the bucket
water inlet valve must be closed.
4. When using bucket water, please plug the inlet valve
with a plug to prevent water leakage.
5. Please note the "Water inlet port" and "Water draining
port" signs at the interface.
6. The ice maker's drainage depends on gravity, so the
drainage pipe must have sufficient slope and drop.
Warning: Please only use drinking water.

Installation
Operation
The pipe connections on
the unit are marked. In
case of conflict, the
identification on the unit
shall prevail.

Indicator light display (5)
1. Ice full display light (red) When the ice full alarm is on, it
always lights red.
2. The water shortage indicator (red) lights red when the
water shortage alarm occurs.
3. After the thin ice indicator (green) is selected, the
standby state flashes, and it always lights green when it is
turned on.
4. After the ice indicator light (green) is selected, the
standby state flashes, and it always lights green when it is
turned on.
5. After the thick ice indicator (green) is selected, the
standby state flashes, and it always lights green when it is
turned on.
Function keys (2)
1. The on / off button controls the power on and off, long
press for 3 seconds to enter the forced de-icing mode.
2. Ice type selection button click to select ice type, long
press for 3 seconds to start cleaning mode.

Ice machine working steps
1. Ice making: Connect the water source, turn on the
power, press the on / off button, the fan starts, and the ice
making time is judged according to the ambient
temperature. The compressor starts, the circulating water
pump starts, and ice making begins. When making ice, the
water pump continues to work, and the water flow will flow
down from the top of the ice tray into the sink, and the
water will slowly cool down until it freezes. When the ice
cube reaches the predetermined time, the program will
shift to the de-icing step.
2. De-icing: In the de-icing procedure, when the reversing
valve is opened, the ice tray will be heated, and the
connection between the ice cube and the ice tray will be
melted. When the ice cube cannot be attached to the ice
tray due to its own weight, it will be Will fall down and
complete one-time de-icing process. When the ice falls, it
will flip the flap, and then the flap will be reset due to its
own weight, and then the machine will start the next ice
making. When too many ice cubes in the refrigerator cause
the ice cubes to press against the water baffle and make it
impossible to reset, the control chip judges that the ice is

full and stops temporarily, and cannot start until the water
baffle is reset.
3. Forced de-icing: During the ice-making process, press
and hold the on key for 3 seconds, the machine will enter
the de-icing procedure in advance, and after the de-icing
will continue the next round of ice making.
4. Cleaning function: turn on the power, turn on the water
source, long press the selection button, the machine will
enter the automatic cleaning program, it will automatically
shut down after 10 minutes. After the cleaning procedure is
completed, please unplug the drain port to drain the
sewage.
Note: In summer and hot environment, it is recommended
to adjust the ice thickness range: 15 ~ 29 min. In winter
and cold environment, it is recommended to adjust the ice
thickness range: 10 ~ 18 min.
Fault indication: ice full light flashes quickly: ambient
temperature (sensor) fault, shutdown
The ice full indicator and the water shortage indicator flash
alternately: the open and closed signals of the ice full
switch cannot be detected for 3 consecutive times, the
machine stops working and reports a mechanical failure.

Fault self-diagnosis
1. The pump-can directly observe whether there is water
flowing down from the ice tray. If not, the pump may
malfunction.
2. Refrigeration-After the ice making operation lasts for 10
minutes, the water in the sink will become significantly
colder. You can directly touch the ice tray or running water
to feel the water temperature.
3. Inlet water-during the automatic cleaning process, water
can be observed in the overflow pipe of the sink
continuously flowing into the ice storage bucket. During the
ice-making process, you can reach into the sink by hand to
feel the amount of water. Normally, it accounts for more
than half of the sink. Note: In summer and hot environment,
medium and large ice stalls are recommended. In winter
and cold environments, small ice and medium ice stalls are
recommended.
