Safety
This appliance is not intended for use by individuals (including children) with reduced physical, senso-
ry, or mental capabilities, or lack of experience and knowledge, unless they are supervised by a person
responsible for their safety.
If the power cord is damaged, it must be replaced by a special cord or assembly available from the
manufacturer or its service agent.
If the power cord is damaged, it must be replaced by the manufacturer, its service agent, or similarly
qualied personnel to avoid a hazard.
The rated voltage is 115V; the rated frequency is 60Hz.
If the working voltage is too low or too high, the compressor will be damaged.
- Using three-hole socket (Grounding):
To ensure safety, the socket and cord must be rated for more than 10A of electricity.
Always make sure all sockets are properly grounded. Do not use a damaged power cord or plug. Firm-
ly connect the plug to the socket. Improper connections may cause a re.
After the machine is properly positioned, ensure the plug is securely inserted. Users can safely re-
move the plug in case of emergencies.
- Do not damage the power cord:
When unplugging, grasp the plug, not the cord. Do not pull the cord.
Avoid pressing the power cord. Be careful when carrying the product. Do not damage the power cord.
- Using and Carrying:
To avoid hazards, do not press or pull the glass door, as it may break easily.
When moving or transporting the unit, ensure that the front side is not pressed to prevent damage.

avoid electrical insulation issues and re hazards.
Before cleaning or servicing, turn off the appliance and unplug it. Before plugging it back in, wait at
least 5 minutes to avoid damaging the compressor.
The fridge door is glass; ensure it is not foaming. The fridge room is only for refrigeration, not freez-
ing.
Do not store bottles of beverages in the freezer to avoid breakage.
Ensure the shelf is properly installed, as improper installation may cause it to fall. This product is only

Set-up
When opening the packaging, ensure all accessories are accounted for. After checking, repack se-
curely before transporting.
- During handling or transportation, avoid tilting the packing by more than 45 degrees and minimize
any strong shaking to protect the cooling system.
- The placement surface must be solid and level to ensure the machine sits securely. This is important
for safety.
- The user should not place anything within 3 in. of the product to ensure the showcase functions
eciently and safely.
- Before connecting to electricity, ensure the plastic plug cover is removed.
Do not place any food inside until the machine is powered on and has been running for some time.
Then, you can put in the food.
- The machine must be placed on a at, solid surface.
If the machine needs to be raised, the cushion must be at and solid. Do not use ammable materi-
als. Never leave packing materials like pecking or foam under the machine as a cushion.
- Do not place the machine in a damp area where it might get wet or contaminated.
Clean it with a soft cloth as soon as possible to avoid rust and insulation issues.
- Do not place the machine in extremely cold environments or outside where it may be exposed to
rain.
- To avoid affecting performance, do not place the machine under direct sunlight or near heat sources.

Operation
Usage for the First Time
- Keep the machine in a good position and open the door to ventilate.
- Although the machine is already cleaned from the factory, please clean it before using it.
- The machine should run empty for some time.
Then, set the thermostat and connect it to electricity to begin operation. Because the machine may
become slightly warm during normal operation, the compressor should stop after a short period.
Once the interior temperature decreases, the machine will automatically resume operation. We rec-
ommend waiting until the interior temperature has fully cooled before placing items inside the show-
case.
Thermostat
The cabinet temperature is controlled by the thermostat on the panel. The thermostat can be adjusted
to set an appropriate temperature range based on different ambient conditions and the quantity and
type of goods stored.
On the thermostat knob, there are positions numbered from 1 to 7.
(Note: Positions 1 to 7 indicate refrigeration levels, not specic temperatures.)
Position 1 = Highest temperature setting (less cooling).
Position 7 = Lowest temperature setting (maximum cooling, runs continuously).

Maintanence
Cleaning
• Before cleaning, unplug the appliance.
• Use a soft cloth or sponge with clear water or mild soap.
• Do not use organic, alkaline, or hot water, as it may damage the showcase.
• Do not use water to clean the compressor room. After cleaning, use a cloth to dry the area to avoid
rust.
• Let hot food cool before placing it in the fridge room. Hot food can damage the cooling system.
• When placing food, ensure it’s a safe distance from the cooling air outlet and inlet. Obstructing
airow can damage the cooling system.
• When the machine is running, avoid frequently opening the door. Keep the door closed to maintain
proper cooling.
• If there’s a power outage, wait 5 minutes before turning the appliance back on. This prevents po-
tential damage.
• If the interior temperature rises due to a power outage or other failure, the machine may short
cycle. We recommend stopping use and allowing the machine to rest.
• Please unplug the appliance if it won’t be used for an extended period, and clean it to prevent
odors.
• To extend the machine's life, do not interrupt power for short periods. Wait at least 5 minutes be-
fore restarting.

Manual Defrosting Instructions
Manual Defrost Freezer models must be defrosted manually. For best performance, the freezer
should be defrosted when the frost accumulation reaches 1/4 to 1/2 inch thick. Follow these steps
for manual defrosting:
1. Unplug the freezer.
2. Remove all food and place it in insulated boxes, insulated bags, picnic coolers, etc.
3. Use towels and newspapers for insulation, as needed.
4. Remove the drain plug (on models so equipped).
10
5. With the door open, use pans of hot water to speed up the defrosting process. Remove large piec-
es of frost as they form.
6. Sponge the excess water from the bottom of the freezer as it collects.
7. After defrosting, clean the inside of the freezer with baking soda and water. Rinse and dry.
8. Replace the drain cap (if equipped). Return the drain tube to its position and replace the grille.
9. Plug the freezer back in, reset the temperature control, and return food to the freezer.
(For refrigrator model)
Defrost Water
Normally, when the compressor stops, the body temperature will rise. Evaporator frost will thaw and
ow to the water box in the compressor room via the drain hose. Users do not need to manually de-
frost the unit. The water in the water box will evaporate due to the heat when the compressor is run-
ning, so there is no need for manual defrosting.
Illumination
The light switch is located on the top right.
Press "0": Lamp is off.
Press "1": Lamp is on.
Replace the Light Bulb
If the light is damaged, please contact professional maintenance. Do not attempt self-repair.
