Earth bar

6
Prevent from flammables and explosive
Never put any flammable or explosive inside the refrigerator such as ether, gasoline, alcohol, adhesive
and explosive. Never put dangerous product nearby the refrigerator.
No spray
To spray the flammables such as paint or coating nearby the refrigerator is not allowed, otherwise fire
might be resulted.
After power break
After power break or unplugging the refrigerator, always wail at least 5 minutes and then you may plug the
refrigerator and start it again.
No medicine
No medicine is allowed to keep inside the refrigerator.
1. Before use:
Plug the refrigerator on 220-240V~ exclusive socket.
After the refrigerator running, put hand on the air suction to confirm it is sufficient cold. Then you may put
food inside the cold box.
2. Digital temperature controller
Features Of Function
- It is a mini-sized and integrated intelligent controller and applicable to the compressor of one Hp.
Use and Caution

The main functions are:Temperature Display/Temperature Control/Manual, automatic defrost by
burning off/Illumination Control/Value Storing/self Testing/parameter Locking
Front Panel Operation
1. Set temperature
2. Press „set“ button, the set temperature is displayed.
3. Press or button to modify and store the displayed value.
4. Press „set“ button to exit the adjustment and display the cold-room temperature.
5. If no more button is pressed within 10 seconds, the cold-room temperature will be displayed.
6. Illumination: Press button, it lights; Press again, it stops.
7. Manual start/stop defrost:Press button and hold for 6 seconds to defrost or stop defrost.
8. Refrigerant LED: During refrigeration, the LED is on; When the cold room temp. is constant, the LED
is off; During the delay start, the LED flashes.
9. Defrost LED: During defrosting, the LED is on; When is stops defrosting, the LED is off; During the
delay display of defrost, the LED flashes.
3. Cautions
1. Shorten the door open time and reduce open frequency is good to keep a cold temperature inside the
refrigerator.
2. Never block the air suction and outlet. Keep air circulation and refrigeration capability.
3. Do not make food congested as it will influence the cooling effect. Adjust the rack height for proper
food storage.
4. Cool the hot food down to room temperature before you put it into the refrigerator.
5. Try to reduce the open times and keep refrigerator inside cold in case the power is cut off.
6. Only skilled service man is allowed to repair the damaged power cable with special tools.

Trouble
Cause and Remedy
No refrigeration
Is the plug in socket well?
Is the fuse broken?
Is there no power?
Unsatisfactory
refrigeration
Is it under the sunshine?Is there any heat source nearby?
Is the surrounding ventilation bad?
Does the door close well? Does door open for a long time?
Is the door seal strip deformed or damaged?
Is food congested or too much?
Does food block the air suction or outlet?
Regulate the temperature controller.
Much noise
The refrigerator does not level.
The refrigerator contacts wall or other matter.
There is loose part in refrigerator.
Contact local service agent for help if simple trouble shooting does not solve the problems.
Note:
Following phenomena are not troubles
1. The murmur of water is heard when the refrigerator is working. It is a normal phenomenon as the
coolant is circulating in the system.
2. In wet season, condensation might be found on the outside of the refrigerator. It is not a trouble, which
is caused by high humidity. Simply use cloth to wipe it.

The principle of compression refrigeration consists of “compression”, “condensation”, “throttling” and
“vaporization”. The compression is undertaken by compressor, the condensation is completed by
condenser, the throttling valve is executed by capillary and the vaporization is implemented by evaporator.
When the coolant is circulating in the closed refrigeration system, the compressor sucks coolant, which
has absorbs heat in evaporator, the coolant becomes a high pressure and high temperature gas. In
condenser, it dissipates heat in air, while the coolant is re-liquefied and throttled in capillary and then
enters into evaporator with low pressure. The liquefied coolant quickly boils and vaporizes into gas when
the pressure suddenly drops. Meanwhile, it absorbs heat inside the refrigerator. And the compressor sucks
the low pressure and low temperature gaseous coolant,….It is circulating in this way up to realization of
intended refrigeration.
