3.Safety Cautions
1) This unit uses AC115V/60Hz power, there should be a 500va
stabilizer if the voltage fluctuation exceed AC99V～132V
2) The user should hold the plug when the power is on/off, dragging or
pulling the power cord is prohibited.
3) Do not remove the power cord or plug
4) Must use dependent socket and reliable ground wire. Ground wire
must not connect with the null line of the gas pipe, warm gas pipe, water
pipe and must be single power
5) Never splash water on the unit directly.
6) Keep away from explosive, hazardous goods such as ether, gas,
alcohol, bonding agents, gunpowder etc.
7) Keep away from spray of inflammables such as paints, coating
materials etc.
8) After the unit is switched off, it should not be restarted within 5
minutes.
9) Do not leave the power cord under any heavy objects including the
unit itself.
10) Do not drill holes or install other objects on the casing.
11) This cooler is not suitable for storage pharmaceutical products.
4.Portage and storage
1) Keep the unit vertical when carrying the unit, the angle to the
horizontal line should not be over 50 °，otherwise it will damage the
compressor and affect normal operation of the unit.
2) The unit should be place on a solid and firm ground, take away the
bottom pack to lower the shock and noise.
3) Leave at least 20 cm of distance between the back of the unit and the
wall for ventilation and leave a space with an open angle of 160 °for the
door.
4) Keep the unit away from heat sources and avoiding direct sunlight.
5) Never place the unit on a location where water can reach or with high
moisture. Splashed water and dirt should be wiped off in time by using
a soft cloth.

3) Adjust the foot to make the unit steady according to the ground
condition to lower the shock and noise.
Problems
Possible cause
Ways to solve problems
Abnormal operation of
the compressor or has
buzz sound
The power voltage
is out of the rated
range.
Disconnect the power supply
immediately and reconnect
with it after normal voltage.
It is necessary to have a
voltage stabilizer in case of
poor power supply.
Compressor operates
too
long time and no frost
on the surface of inner
cabinet
Refrigeration system
is at fault (leakage
or blocked)
Send the unit to service
department for repair
There is frost or ice on
the walls of the inner
cabinet and too low
internal temperature,
the compressor
operates never stop
Thermostat does not
work
Ask service department for
repair
The internal
temperature is too
high and the
compressor operates
never stop
Bad heat issipation
and ventilation of
casing, the ambient
temperature is too
high
Improve ventilation and ower
the ambient mperature.
Too much warm
food was put in at
one time
Take out some food
Door open requently
and long time door
opening
Decrease number and time of
door opening.

4) After moving the unit, place the unit for 30 minutes before switching it on.
Running: close the door and connect the power, turn on the lamp switch on the
control panel, the lamp is on. Half an hour later, the temperature inside the case
lower apparently, it indicates the unit on be normally used
5) After connecting the power, the unit should be kept empty for one hour.
6.Setting and adjustment of temperature
1) Adjust the storage temperature through the temperature controller located on
the back of the case(see the picture), adjust the temperature according to the
ambient temperature and the foodstuff.
2) See the following picture about the knob scale. The temperature adjustable
capacity is from “1”-“5”, adjust the storage temperature by turning the
temperature controller clockwise. The higher of the number shows the lower of
the storage temperature. The knob can turn freely but can't turn clockwise from
“5”to “1”. Factory setting position is on “3”.

3) Check if the scale is on an appropriate position before using,
frequent adjustment is not appropriate when using. Normally in
summer, the ambient temperature is high, anti clockwise turn the knob
to “2”, while in winter, the ambient temperature is low, clockwise turn
the knob to “4”.
4) Position “0” represent stop running.
7. Storage of articles
1) Do not put large amount of articles into the unit at one time, you should
leave some space around the foodstuff to let cold air inside the cabinet counter
to flow. Keep bottled articles away from the walls of interior cabinet so as not
to freeze it until broken.
2) Do not put warm food into the unit directly until they are cooled under
normal temperature, it will facilitate to lower its energy consumption and
prolong service life of the compressor.
8. Maintenance
Disconnect the power supply before maintenance for the machine!
1) Keep the door gasket clean, remove it from the door and wash it.
Dry and seal it as before. Putting some talcum powder on the magnetic
surface would prolong its service life.
2) Bulb replacement：remove the lamp shade, take out the bulb,
replace with a new bulb, then mount it again.
3) If there is heavy frost on the evaporator after long usage, take out the
stuff inside the case, disconnect the power, the frost will melt
automatically, clean up the water and connect the power again.
4) Use a soft cloth and dip some water or soap (Non-caustic, neutral
detergent is also available) to clean the unit. Dry the unit after cleaning
to avoid rust.
