Structure and Parts

Handle and Erection

Handle with care
Unplug the wall socket first.
Never tilt it over 45 degree during handling Dry place
Always locate the refrigerator at a dry place. Sufficient space
The distance from both sides and back of refrigerator to wall or other substance must not less than 10cm.The refrigeration capability might be decreased if its surround space is too small to circulate air. Well ventilation
Always locate the refrigerator at a place with fine ventilation. For the first time use, wait for 2 hours after handling and then plug the wall socket and start it. Far from heat source
Never place the refrigerator directly under the sunshine .Never locate it nearby any heat source or heater to prevent it from reducing refrigeration capability. No heavy load
Never put any heavy load on the top of the refrigerator. No hole making
Never make hole on the refrigerator. Never install other matter on the refrigerator. Stable location
Unpacking and locate the refrigerator on a flat and solid place.

Preparation and Power Supply

Exclusive power socket
Normally, the power supply should be 220-240V, single phase AC with exclusive single phase three pin receptacle (250V 10A) and fuse (6A).The power receptacle must have a reliable earth connection. No share on socket
Never let the refrigerator share the common socket with other appliance, otherwise the cable becomes hot and fire might be resulted. Protect cables
Never break or damage the cables otherwise current leakage and fire might be resulted. No water flushing
Never give the refrigerator surface a flush otherwise current leakage might be resulted.Never give the refrigerator surface a flush otherwise current leakage might be resulted. 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.

Use and Caution

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
   It is a mini-sized and integrated intelligent controller and applicable to the compressor of one Hp.
   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
   Press „set“ button, the set temperature is displayed.
   Press or button to modify and store the displayed value.
   Press „set“ button to exit the adjustment and display the cold-room temperature.

2. If no more button is pressed within 10 seconds, the cold-room temperature will be displayed.

3. Illumination:Press button, it lights; Press again, it stops.
   Manual start/stop defrost:Press button and hold for 6 seconds to defrost or stop defrost.

4. 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.

5. 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
Shorten the door open time and reduce open frequency is good to keep a cold temperature inside the refrigerator.
Never block the air suction and outlet. Keep air circulation and refrigeration capability.
Do not make food congested as it will influence the cooling effect. Adjust the rack height for proper food storage.
Cool the hot food down to room temperature before you put it into the refrigerator.
Try to reduce the open times and keep refrigerator inside cold in case the power is cut off.
Only skilled service man is allowed to repair the damaged power cable with special tools.
Never touch compressor to avoid from scald.
If the supply cord is damaged, it must be replaced by the manufacturer, its service agent or similarly qualified persons in order to avoid a hazard.
This appliance is not intended for use by persons (including children) with reduced physical, sensory or mental capabilities, or lack of experience and knowledge, unless they have been given supervision or instruction concerning use of the appliance by a person responsible for their safety.
Children should be supervised to ensure that they do not play with the appliance.
The operation manual are not suitable for the persons (including children) with reduced physical, sensory or mental capabilities,or lack of experience and knowledge.

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(table ware 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 is damaged, it must be replaced by the manufacturer, its service agent.

Trouble Shooting

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
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.

Principle of Refrigeration System 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,……….It is circulating in this way up to realization of intended refrigeration.
