3. Unpack
Before unpacking, check whether the anti-tilt
mark (if any) is in good condition, whether the
outer packing of the machine is in good
condition, and whether the machine model is
in accordance with your purchase;
Open the package to check the appearance
of the machine, take out the accessories and
random documents, and check the packing
list is consistent;
remove the protective film on the housing
(recommended).
If there is any discrepancy or damage, please
contact our company / dealer directly.
4. Installation Location
The ice maker is not suitable for outdoor
usage, the installation location should not be
closed to heat source or be exposed under
direct sunlight.
The normal working ambient temperature
should be ranged between 10°C～38°C, the
water temperature should be between 5°C～
32°C. If the ice-making machine operates
beyond the above normal temperature range
for a long time, its ice-making capacity may be
affected.
Ice makers should be placed near drinkable
water supply. It is recommended that distance
between ice makers be less than one
meterIce-making machine should be placed
near the drinking water source, recommended
from the ice-making machine within one
meter;
Do not block the ventilation window of the ice
maker. There should be enough air
convection space around the ice maker;
The ice maker can not work at sub-zero
temperatures, to prevent supply line failures,
empty the ice maker when the temperature is
below zero(see “preparation for long-term
storage of ice maker” ").
5. Leveling Adjustment
Screw the adjustable part of the four adjusting
bottom feet to the end, and then rotate the
adjusting bottom foot into the corresponding
installation hole at the four corners of the
bottom plate of the ice machine;
Move the ice maker to the installation position.
Use a horizontal ruler to adjust the level of the
ice maker.
Note
Do not use the method of cushioning
hard objects under the bottom foot to adjust
the level of the ice maker. To ensure that the
ice machine four feet stable contact with the
ground, to prevent machine operation
vibration.

Working Process
11. Working process
11.1. Ice melting process: the display screen is
fully bright after power on and completely
extinguished after 1 second.Display C00 indicates
that in the influent state, until the water is full, it
does not enter the power-on delay state, the
deicing indicator lights shine, and the digital tube
displays the power-on delay time. The hot valve
opens, the press opens after 30 seconds, the hot
valve closes after 5 seconds, and deicing after 60
seconds.
11.2. Ice making process: during ice making, the
ice indicator light is on, the digital tube shows the
ice making time, and if the ice skating board is
opened continuously for more than 4 minutes, it
will turn to the ice full state. The compressor
continues to open, the heat valve closes, the fan is
controlled, the upper water valve is controlled 5
minutes before the start of ice making, more than
5 minutes later, and the pump opens after 90
seconds. When the water temperature is lower
than the setting temperature of ice making, start
timing, when the ice making time exceeds the set
time, the ice making ends.
11.3. Deicing process: after the ice making is
finished, it enters the deicing state, the deicing
indicator light is on, and the digital tube shows the
deicing time. Compressor continues to open, hot
valve open, pump, fan closed, upper water valve
controlled. The maximum time limit for deicing is 6
minutes. If the ice is not taken off for 5 minutes,
open the pump for 1 minute. If the ice is still not
taken off, turn to ice making, if the ice is not closed,
turn to ice full. Three times in a row for more than
6 minutes, turn to deicing timeout stop.
11.4. Ice full detection: after the ice is removed, if
the ice in the refrigerator is not full, enter the ice
making state and carry out a new cycle. If the
refrigerator is full of ice, enter the ice full stop state,
ice full indicator light.Water pump, compressor,
heat valve, upper water valve, fan all closed. If the
ice is removed, within 180 seconds of the press
closing, the ice full indicator lights shine. If the
pressure mechanism is closed for 180 seconds,
turn to power up for a new cycle. If the ice is not
taken away, it is always in a state of ice.
12. Operational inspections
Make sure the tap is open.
Make sure the inlet valve is open.
The ice maker has been powered on.
Check all pipes and fittings to ensure no
leakage.
▲ attention
The ice maker has been tested and debugged
in the factory before shipment. The new
machine does not need any debugging. In
order to ensure the normal operation of the
ice maker, operation inspection is required
under the following circumstances;
Initial initiation
Restart after long downtime
After cleaning and disinfection

any alcoholic liquid to clean or disinfect the
ice maker, otherwise it may cause cracks
in plastic parts;
Remove the roof and back panel, and
should be removed by maintenance
personnel with relevant knowledge;
Do not wash plastic parts in water or
dishwasher above 40℃ temperature to
avoid damage to parts.
Environmental cleaning: often clean the ice maker
to keep the environment clean and make the
equipment run efficiently.

sponge dipped in neutral cleaning liquid and
dry with clean soft cloth. Use stainless steel
cleaners if necessary.
Air filter cleaning: filter can filter dirt or dust in
the air to prevent condenser clogging. If the
filter is blocked, the performance of the ice
maker will decline.It is recommended that air
filters be cleaned once or twice a month:

Maintenance
15. Out of use/Winterization
Note
If water is left in the machine in an
environment below 0°C, it may cause serious
damage to the machine parts. This fault is not
covered by warranty
Special protection measures are
required if the ice maker is out of service for
a long period of time or exposed to an
environment of 0°C or less. Follow these
steps below:
Disconnect the power to the ice maker.
Disconnect the water supply to the ice
maker.
Empty the sink.
Remove water inlet hose and drain it
from the water inlet.
Ensure that there is no water residue in
the inlet, drain and distribution pipes.
16. Maintenance
Before applying for repair, please consider the
following aspects in order to quickly identify and
improve the efficiency of machine recovery.
a). Whether the water supply is normally,
including faucets open, inlet valve not blocked,
and water pressure is in 1bar~5bar.
b). Whether the power supply is normal,
including voltage is in ±10% of rated
voltage, power switch is connected, the fuse
is not burnt out and whether the plug is
fixed well.
c). Whether the ambient temperature is too
high or too low (the operating temperature range
of the ice maker is 10°C～38°C), whether the
water temperature is too high or too low (the
water temperature range is 5°C～32°C).
d). Whether the ice bin is full of ice and can
work after ice take away.
