Safety Warnings
- Do not operate the appliance if it is visibly damaged.

- Disconnect power supply before cleaning and maintenance.
Installation and Preparation
Proper placement is crucial for performance and longevity:


- Location: Place in a dry, cool, and ventilated area away from heat sources and direct sunlight.
- Clearance: Allow 30cm at the top, 10cm on the sides, and 20cm at the back for air circulation.
- Surface: Ensure the floor is flat and strong. If not level, adjust the feet to prevent vibration and noise.
- Carpet: If placing on carpet, use wooden boards underneath to prevent discoloration from compressor heat.
Operation and Temperature Control
The refrigerator features a thermostat to control internal temperature:

- Setting: Use the thermostat button (numbered 1-7).
- Recommendation: Setting 3 to 4 is recommended for a balance between freshness and energy saving.
- Quick-freezing: Set the control to 6-7 for rapid cooling, then return to the normal position once finished.
- Stopping: A setting of 0 will force the refrigerator to stop.
Food Storage
- Freezer (Below -18°C): Suitable for meat, fish, and making ice. Wrap meat tightly. Do not store fruit/vegetables here to avoid freeze-drying.
- Refrigerator (0°C to 5°C): Suitable for eggs, butter, milk, and drinks. Use the crisper for fruit and vegetables.
- General: Allow hot food to cool before storing. Use zip-lock or vacuum bags to save space and allow air circulation.
Cleaning and Maintenance
- Cleaning: Unplug the unit. Use a soft cloth with warm water and neutral detergent. Wipe dry. Do not submerge in water or use abrasive agents.
- Defrosting: If frost forms, switch off the device, remove contents, keep the lid open, and drain water from the bottom hole.
- Storage: If not used for an extended period, turn off, clean, dry, and leave the lid slightly open to prevent odors.
Troubleshooting
- Refrigerator does not work: Check power switch, plug connection, fuse, and power supply.
- Compartments too warm: Check if the lid is opened frequently or if a large amount of hot food was recently stored.
- Food is frozen: Temperature is set too low.
- Water flow noise: This is normal, caused by the flow of refrigerant.
- Waterdrops on casing: Normal condensation on cold surfaces.
