Meaning of crossed out wheeled dustbin: Do not dispose of electrical appliances as unsorted municipal waste, use separate collection facilities. Contact your local government for information regarding the collection systems available. If electrical appliances are disposed of in landfills or dumps, hazardous substances can leak into the groundwater and get into the food chain, damaging your health and well-being. When replacing old appliances with new ones, the retailer is legally obligated to take back your old appliance for disposal at least free of charge. ?️
Safety Information
- Handle with care: Unplug the wall socket first. Never tilt it over 45 degrees 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 be less than 10cm. The refrigeration capability might be decreased if its surround space is too small to circulate air. (10cm symbol)
- 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 holes on the refrigerator. Never install other matter on the refrigerator.
- Stable location: To avoid unexpected noise and vibration, unpack and locate the refrigerator on a flat and solid place.

Principle of Refrigeration System
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 a cloth to wipe it.
The principle of compression refrigeration consists of "compression", "condensation", "throttling", and "vaporization". The compression is undertaken by the compressor, the condensation is completed by the condenser, the throttling is executed by the capillary, and the vaporization is implemented by the evaporator. When the coolant is circulating in the closed refrigeration system, the compressor sucks coolant, which has absorbed heat in the evaporator. The coolant becomes a high pressure and high temperature gas. In the condenser, it dissipates heat in the air, while the coolant is re-liquefied and throttled in the capillary, and then enters the 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. The compressor sucks the low pressure and low temperature gaseous coolant. This process circulates to achieve the intended refrigeration.

Preparation and Power Supply
- Exclusive power socket: Normally, the power supply should be 110-120V, 60Hz single phase AC with an exclusive single phase three-pin receptacle. ?
- No share on socket: Never let the refrigerator share the common socket with other appliances, 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 flush the refrigerator surface, otherwise current leakage might be resulted. ?❌
- Prevent from flammables and explosive: Never put any flammable or explosive material inside the refrigerator, such as ether, gasoline, alcohol, adhesive, and explosives. Never put dangerous products nearby the refrigerator. ?
- No spray: Spraying 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 wait 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. ?
Operation and Caution
Part 1:
- Before use: Plug the refrigerator into a 110-120V exclusive socket. After the refrigerator is running, put your hand on the air suction to confirm it is sufficiently cold. Then you may put food inside the cold box.
2. Digital Temperature Controller:
How to See the Set Point:
- Push and immediately release the SET key; the set point will be shown.
- Push and immediately release the SET key or wait about 5 seconds to return to normal visualization.
How to Change the Setpoint:
- Push the SET key for more than 2 seconds to change the Set point value.
- The value of the set point will be displayed and the "°F" LED starts blinking.
- To change the Set value, push the ⬆️ or ⬇️ arrows.
- To memorize the new set point value, push the SET key again or wait 10 seconds.
How to Start a Manual Defrost:
- Push the DEF key for more than 2 seconds, and a manual defrost will start.
3. Cautions:
- Shorten the door open time and reduce open frequency to maintain a cold temperature inside the refrigerator.
- Never block the air suction and outlet to ensure air circulation and refrigeration capability.
- Do not overcrowd the refrigerator, as it will influence the cooling effect. Adjust the rack height for proper food storage.
- Cool hot food down to room temperature before placing it into the refrigerator.
- Try to reduce the open times and keep the refrigerator cold in case of a power outage.
- Only skilled service personnel are allowed to repair a damaged power cable using special tools.
- Never touch the compressor to avoid burns.
Part 2:
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 the 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 is not suitable for persons (including children) with reduced physical, sensory, or mental capabilities, or lack of experience and knowledge.
Do not store explosive substances such as aerosol cans with a flammable propellant in this appliance. During normal operation, the emission noise level does not exceed 70dB(A). The maximum loading of the shelf does not exceed 30kg. The climatic class of the appliance is 4; the units are suggested to be used at 16°C-32°C (60.8°F-89.6°F) ambient temperature. To avoid damages or other problems, this product cannot be put or stored with any corrosive food.
Maintenance
1. Notice:
- Often keep the refrigerator clean; periodical maintenance is necessary.
- Always unplug the socket before maintenance.
- Never use a damaged plug or loose socket to prevent electric shock or short circuit.
- Never flush the refrigerator. Never use alkali detergent, soap, gasoline, acetone, or a brush.
2. Clean outside:
Dip a soft cloth in neutral detergent (tableware detergent) to clean the outside of the refrigerator and then wipe it with a dry soft cloth.
3. Clean inside:
Take racks out for cleaning with water.
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 drying. The glass breaks easily; keep the glass far from children. Clean the condensate tray and wipe it dry.
Trouble Shooting
| 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 the 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 a loose part in the refrigerator. |
Contact a local service agent for help if simple troubleshooting does not solve the problems.
