• WARNING: Do not damage the refrigerant circuit.
• WARNING: Do not use electrical appliances inside the food storage compartments of the appliance, unless they are of the type recommended by the manufacturer.

Maintenance

1. Notice
   Often keep the refrigerator clean and periodical maintenance is necessary.
   Always unplug the socket before maintenance.
   Never use damaged plug or loose socket to prevent from electric shock or short circuit. Never flush the refrigerator.Never use alkali detergent,soap,gasoline,acetone or brush.

2. Clean outside
   Dip soft cloth in neutral detergent(tableware detergent)to clean the outside of the refrigerator and then wipe it with dry soft cloth.

3. Clean inside
   Take rack out for cleaning with water.
   Use soft cloth to wipe the box.

4. Shut down refrigerator for a long time
   Take all food out and unplug the wall socket.
   Clean both inside and outside of the refrigerator thoroughly and open the door for sufficient dry.
   The glass breaks easily.Keep the glass far from children.

5. Replacement of lamp in the light box
   If the LED lamp is damaged, it must be replaced by the manufacturer, its service agent.

Trouble Shooting

No refrigeration

| Is the plug in socket well? Is the fuse broken?

Is there no power?

Unsatisfactory refrigeration

Much noise

| Is it under the sunshine?ls there any heat source nearby? Is the surrounding ventilation bad?

Does the door close well?Does door open for a long lime? 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.

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
The murmur of water is heard when the refrigerator is working. It is a normal phenomenon as the coolant is circulating in the system.
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.

PrinciQle of Refrigeration S}’.stem and Electric Circuit Diagram

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,·········.1t is circulating in this way up to realization of intended refrigeration.
