--Safe Cautions
1. This unit uses AC110V/60Hz power, there should be a 500va stabilizer if the voltage fluctuation
exceeds 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.
--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.
6. Do not place the unit in the environment cold enough to be iced.
--Preparation
1. Remove the carton and packing foam (including the bottom foam)before using.
2. Clean the unit before using.
3. Adjust the foot to make the unit steady according to the ground condition to lower the shock and
noise.
6
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.
--Setting and adjustment of temperature
1. Adjust the storage temperature through the temperature controller located in the internal 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”-“1”. Factory setting position is on “3”
3. Check if the scale is on an appropriate position before using, 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.
--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.
--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.
7
5) Do not use organic liquid, boiled water, washing powder or acid stuff to clean the unit. Rinsing the
case by water is not allowed, don't use hard brush, steel brush to clean the case.
6) If the unit will not be used for a long time, disconnect the power, clean it by following the above
steps, wipe off the water inside the case with a soft cloth.
--Caution
1) The unit is not suitable for storage of blood, pharmaceutical products and biological products
2) Do not place heavy articles on the top of the unit.
3) In case of trouble, please ask professional person for service, do not dismantle the unit without prior
authority to avoid hazard
--Normal Phenomena
1) Sometime hear light sound of water flowing in the unit, this is the sound of refrigerant flowing inside
the pipe.
2) the top ,and the two sides of the casing will be warm, even too hot.
3) In a humidity place, there is dew on the casing or the door, it can dry by dry cloth.
--Troubleshooting guide
Problems
Possible cause
Ways to solve problems
The units does not work
Bad connection of plug
re-connect the plug to power
supply
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 operatestoo
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
evaporator of the inner
cabinet and too low
internal temperature,the
compressor operates
never stop
Thermostat does not work
Ask service department for repair
8
The internal temperature
is too high, and the
compressor operation
doesn’t stop
Bad heat dissipation and
ventilation of casing, the
ambient temperature is
too high
Improve ventilation and improve
the ambient temperature
Too much warm food was
put in at one time
Take out some food
Door open frequently and
longtime door opening
Decrease number and times of
door opening
Too high noise
The unit is not level
Adjust the adjustable foots
The fastener of the unit is
loose
Fasten the loose fastener
Pipes are touching the
compressor
Carefully separate the touching
pipes
Lamp is not on
The lamp is burned out
Replace the lamp
