Operation
First-Time Operation
• Install the appliance according to the installation instructions provided in this manual.
• Open the doors briey to allow air to circulate inside the cabinet.
• Clean the cabinet interior before rst use.
• After installing the appliance, wait at least 30 minutes before powering it on. During transporta-
tion, compressor oil may have owed into the refrigeration system and needs time to settle.
• When the appliance is rst started, the cabinet temperature will initially be higher than the set
temperature. The compressor may run continuously until the desired temperature is reached.
After that, the compressor will automatically cycle on and off to maintain the set temperature.
• Load items into the cabinet only after the internal temperature has stabilized at the set tem-
perature.
Thermostat Operation
• The cabinet temperature is controlled by the thermostat located on the control panel.
• Adjust the thermostat to an appropriate setting depending on the ambient temperature and the
type of goods stored.
• The red indicator light is the power indicator and will illuminate when the appliance is connect-
ed to the power supply.
• The green indicator light is the operation indicator and will illuminate when the compressor is
running.
• The thermostat knob can be rotated to adjust the cooling level:
• Turning the knob toward Freezer / Deep Freeze lowers the cabinet temperature.
• Turning the knob toward Refrigeration increases the cabinet temperature.
• Rotating the thermostat clockwise increases the cooling level, resulting in a lower cabinet tem-
perature.
• Rotating the thermostat counterclockwise reduces the cooling level, resulting in a higher cabi-
net temperature.
• After adjusting the thermostat, allow sucient time for the cabinet temperature to stabilize.
9
General Usage Guidelines
• Leave space between stored items to allow proper air circulation and ecient cooling.
• Store food or materials in sealed containers or bags to prevent odor mixing or drying.
• Allow hot items to cool to room temperature before placing them in the appliance. Placing hot
items inside may affect the cooling performance.
• Open the door only when necessary and keep it open for the shortest time possible.
• Always ensure the door is fully closed to reduce energy consumption.
• Label stored items with the storage date to help track storage time.
• Follow a rst-in, rst-out (FIFO) storage practice by using the oldest stored items rst.
• Adjust the temperature according to the type of goods being stored. Setting the temperature
lower than necessary will increase energy consumption.
• After switching off the appliance, wait at least 5 minutes before restarting to prevent compres-
sor damage.
• If a power outage is expected, set the thermostat to a lower temperature in advance and mini-
mize door openings to preserve the internal temperature.
• During a power outage, keep the door closed and avoid adding new items to the appliance.

Maintenance
Cleaning and Care
Regular cleaning and proper maintenance will help extend the life of your chest freezer and keep it
performing optimally.
• Always unplug the unit before cleaning or performing maintenance.
• Clean the interior and exterior with a soft cloth using mild detergent and warm water.
• Do not use hot water, abrasive cleaners, or corrosive chemicals.
• Clean the door gasket regularly with a mild solution (such as diluted bleach), then wipe it with
clean water afterward.
• After cleaning, dry all surfaces thoroughly before reconnecting power.
After maintenance, check the following:
1. Ensure the power plug is securely connected.
2. Conrm the power cord is not damaged or overheating.
3. Check for cracks or wear on the cord.
If the unit will not be used for an extended period, unplug it, remove all contents, clean thoroughly,
and allow it to dry completely before storing.
Defrosting
Moisture inside the freezer may cause frost to form on the interior walls during operation. Excess
frost buildup can reduce cooling eciency.
When frost reaches approximately 0.2–0.3 inches (5–7 mm) in thickness, defrosting is recom-
mended.
To defrost:
1. Turn off and unplug the freezer.
2. Remove all stored items.
3. Leave the lid open and let the frost melt naturally.
4. Use a plastic scraper (if needed) to gently remove softened frost.
5. Drain the water through the drain outlet (if equipped) and wipe the interior dry.
6. Plug the unit back in and let it reach the desired temperature before returning the items.
Important
Do not use sharp metal tools or electrical heating devices to remove frost, as this may damage the
interior surfaces or cooling system.
