- Power off the refrigerator and remove all objects from the door trays.
- Dismantle the hinge cover, screws, and upper hinge. Remove the hole cap and pins from the opposite side.
- Remove the door, then remove the lower hinge assembly and leveling foot. Interchange their positions and reinstall them.
- Install the door on the lower hinge assembly, then install the upper hinge, hinge cover, pins, and hole cap in sequence.
Changing the Light (Optional):
To replace an incandescent lamp:
- Disconnect the power supply.
- Hold and remove the light bulb cover.
- Unscrew the old bulb counterclockwise.
- Replace with a new bulb (Max. 15W) by screwing it clockwise, ensuring it is tightly fixed.
- Reassemble the light cover and reconnect the refrigerator to the power supply.
Starting:
- After initial placement, keep the refrigerator still for half an hour before connecting it to the power supply.
- Before storing any fresh or frozen foods, allow the refrigerator to run for 2-3 hours, or for over 4 hours in summer when ambient temperatures are high.
- Ensure enough space for convenient opening of doors and drawers.
Energy Saving Tips:
- Locate the appliance in the coolest area of the room, away from heat-producing appliances, heating ducts, and direct sunlight.
- Allow hot foods to cool to room temperature before placing them in the appliance. Overloading forces the compressor to run longer, which can lead to food spoilage.
- Wrap foods properly and wipe containers dry before placing them in the appliance to reduce frost build-up.
- Do not line appliance storage bins with aluminum foil, wax paper, or paper toweling, as liners interfere with cold air circulation and reduce efficiency.
- Organize and label food to minimize door openings and extended searches. Remove multiple items at once and close the door promptly.
