OPERATION
TEMPERATURE CONTROL
The freezer is pre-configured and set to "4" by default upon first use. The temperature inside the freezer cabinet
is regulated by the thermostat control knob, located on the external right side of the freezer. The markings "1 –
MAX" indicate the different temperature settings, with "1" representing cold and "MAX" indicating the coldest
range (-0.4℉ to -14.8℉). The factory default setting is "4", with the internal temperature approximately -7.6℉.
Typically, setting "4" or "5" is suitable for ice cream and similar products. Setting it to "MAX" will cause the
compressor to run continuously.
NOTE: Please avoid running it at “MAX" for more than 24 hours. We do not recommend adjusting the temperature.
If adjustment is necessary, simply use an ordinary flat screwdriver to change the temperature.
It is recommended to install the freezer in an area where the ambient temperature ranges between 50°F (10°C) and
below 90°F (32°C). If the ambient temperature exceeds or falls below these recommended ranges, it may affect the
performance of the freezer. For instance, placing the freezer in extremely cold or hot conditions can lead to
fluctuations in interior temperatures.

movement, your freezer come equipped with two locking wheels.
To lock:
Step on and press down the locking lever into the locked
position. You may need to apply some pressure to engage the
lock fully.
1.
Once engaged, the wheel should no longer rotate freely,
securing the freezer in place.
2.

OPERATION
FOOD STORAGE
Ensure adequate spacing between items in the freezer to allow for proper ventilation and even freezing.
Wrap moisture-sensitive foods in sealed bags to prevent odor mixing and frost formation.
Always cool food before placing it in the freezer; avoid putting hot food directly inside.
The freezer is designed for storing and displaying packaged foods only.
DEFROSTING
Under typical ambient conditions, the freezer usually does not require defrosting. However, in colder ambient
temperatures and/or high humidity, some frost may accumulate. To defrost the freezer, simply set the thermostat
dial to “OFF”, and defrosting should occur within a few hours. Once defrosting is complete, return the thermostat
control knob to the desired setting. For faster defrosting, you can remove all items from inside the cabinet, unplug
the freezer, and leave the sliding display door open. It's important to never use a knife or any other metal instrument
to scrape ice or frost.
PLACEMENT OF YOUR FREEZER
Position the freezer in a dry and well-ventilated place, away from direct sunlight, heaters, and corrosive gases or
chemicals.
Clean the interior surface with lukewarm water using a soft cloth.
Place the freezer on a hard and level floor that is strong enough to support it when it is fully loaded. Installing on
carpet is not recommended.
If the freezer needs to be lifted, two or more people should move the freezer. Failure to do so can result in back
or other injury.
NORMAL SOUNDS
Your new freezer may produce sounds that are unfamiliar to you. Hard surfaces, like the floor and walls, can amplify
these sounds. Here are common sounds you may hear and their possible causes:
Rattling Noises
These noises may originate from the flow of refrigerant or the water line. Items stored on top of the freezer can
also contribute to rattling sounds.
Compressor Sounds
The high-efficiency compressor may emit pulsating or high-pitched sounds during operation.
Water Flow
Water running from the evaporator to the water reservoir may result in a splashing sound.
Refrigerant Circulation
At the end of each cycle, you may hear a gurgling sound caused by refrigerant flowing in the freezer.
Condenser Fan
You may notice the sound of air being forced over the condenser by the condenser fan.
Please note that an individual’s perception of noise is directly influenced by the environment in which the freezer is
situated. Our freezers adhere to international standards for such equipment and incorporate the latest technical
advancements. It's important to understand that some level of noise from the compressor and coolant circulating in
the system is inevitable.
POWER INTERRUPTION
If the freezer is unplugged, encounter power interruption, or turned off, you must wait 3 - 5 minutes before
restarting the freezer. If attempted to restart before this time delay, the freezer may not start.
Page 9
CARE AND MAINTENANCE
PREPARING FOR STORAGE
If the freezer will not be used for an extended period or is to be moved to another location, it's necessary to defrost
the unit and dry the interior.
Disconnect the freezer from the power supply by unplugging the power plug from the wall socket. WARNING:
Do not touch the power plug with wet hands. Never unplug the unit by pulling the cord.
1.
Leave the sliding display door open to facilitate air circulation and prevent mold, mildew, and unpleasant odors.2.
CAUTION: Store the unit out of reach of children.
CLEANING YOUR FREEZER
Turn off the power, unplug the freezer, and remove all items including shelves.
Wipe the interior with a warm water and baking soda solution. The solution should consist of about 2
tablespoons of baking soda to one quart of water.
Clean the shelves with a mild detergent solution.
Wipe the exterior cabinet with warm water and mild liquid detergent.
Avoid using steel wool or steel brushes on the stainless steel surface, as these may cause erosion and rusting.
VACATION TIME
For short vacations lasting less than two days, leave the freezer operating.
For longer vacations, if the freezer will not be used for an extended period, remove all items, turn off the freezer,
and thoroughly clean and dry the interior.
MOVING YOUR FREEZER
Remove all items from inside the freezer.
Securely tape down (we recommend using painter’s tape) all loose items (such as shelves) inside your freezer.
Turn the adjustable legs up to the base to avoid damage.
Tape (we recommend using painter’s tape) the sliding display door shut.
Ensure the freezer remains secure in the upright position during transportation and protect the exterior with a
blanket or similar item.
ENERGY SAVING TIPS
Position the freezer in the coolest area of the room above 50°F (10°C) and below 90°F (32°C), away from heat-
producing freezers and direct sunlight.
Ensure adequate ventilation around the freezer. Never block the air vents.
Keep the sliding display door tightly closed and avoid frequent or prolonged opening.
Organize the contents inside the freezer.
Avoid overfilling the freezer to allow for proper air circulation.
