Operating Instructions
1. Temperature Control
The refrigerator features an electronic lock type for temperature settings. Refer to the internal control dial or panel for adjusting the cooling level. Higher numbers typically indicate colder settings.
2. Fresh Room
Utilize the dedicated Fresh Room compartment for storing delicate items that require slightly cooler temperatures than the main compartment, such as dairy products or pre-cooked meals.
3. Big Bottle Guard
The Big Bottle Guard in the door allows for convenient storage of larger beverage bottles, maximizing usable space within the refrigerator.
4. Digital Inverter Compressor
Your refrigerator is equipped with a Digital Inverter Compressor, which automatically adjusts its speed in response to cooling demand. This results in quieter operation, reduced energy consumption, and enhanced durability.
5. Home Inverter Compatibility
This appliance is designed to run efficiently on a home inverter, providing uninterrupted cooling during power outages.

Maintenance and Care
1. Cleaning
- Interior: Clean the interior regularly with a mild detergent and warm water. Rinse thoroughly and dry. The spill-proof toughened glass shelves can be removed for easier cleaning.
- Exterior: Wipe the exterior surfaces with a soft, damp cloth. Avoid abrasive cleaners.
- Door Seals: Keep door seals clean to ensure a tight closure and efficient operation.
- Safe Clean Back: The refrigerator features a safe clean back design, making it easier to clean the rear of the appliance and prevent dust accumulation.
2. Defrosting
As a direct-cool refrigerator, manual defrosting is required when ice buildup in the freezer compartment reaches approximately 0.5 cm (1/4 inch) thickness. To defrost:
- Unplug the refrigerator from the power outlet.
- Remove all food items and place them in a cooler.
- Leave the refrigerator door open to allow ice to melt naturally. Do not use sharp objects or heating devices to speed up defrosting.
- Once defrosted, clean and dry the interior thoroughly before plugging it back in and returning food items.
