• Failure to unplug the freezer during an extended power outage could result in electrical shock or personal injury.

SPECIFICATION

IDENTIFICATION OF PARTS

OPERATION

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.

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.

LOCKING THE WHEELS

These wheels are pre-installed and are integral to the functionality of your appliance. Please note that these wheels are not intended to be removed. To ensure stable positioning and prevent unwanted movement, your freezer come equipped with two locking wheels.

To lock:

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

To disengage:

1. Pull up the locking lever into the unlocked position. You may hear or feel a click as the lock disengages.1.
2. With the lock released, you can now move the freezer as needed.

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 food sonly.

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.

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.

1. 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.
