When using this product for the first time, please pay attention to the meaning of the following warning signs
and carefully read the safety precautions, so that you can use this equipment safely and correctly.
Warning: Failure to observe the precautions may result in serious personal injury
or death.
Do not touch the equipment with wet hands to avoid electric shock; Equipment shall not be grounded through
gas pipeline, water supply pipeline, telephone line or lightning rod, which may easily cause electric shock.
This equipment can only be installed by professional technicians or after-sales maintenance personnel, it
may cause electric shock or fire.
Be sure to install the equipment on a solid and flat ground and take due care to prevent tipping over. If the
ground is not solid enough or the installation location is not appropriate, it may cause the equipment to fall
over and cause equipment damage or personal injury.
Please handle the power cord carefully to avoid short circuits or open circuits. Please turn off the power
before pulling out the power plug. Hold the power plug carefully and pull it out. Do not pull the wires of the
power plug. Otherwise, it may cause electric shock or fire due to the short circuit.
Don't bundle the power cord, don't press it under furniture or heavy objects, and don't get close to heat
sources such as compressors.
Please insert the power plug into the outlet tightly to ensure firmness and reliability, so as to avoid electric
leakage; After installation, the power plug must be within reach, so that the power plug can be unplugged in
time in case of emergency.
Separate special outlets must be used and grounded reliably. The cross-sectional area of the copper
2
conductor in the wall connected with the outlet must be more than 4mm . Do not lengthen the power cord
without authorization to avoid heating or fire.
Do not use the power supply that is not specified in the equipment design, so as to avoid overheating, short
circuit and other faults. For example, connecting 110 V rated voltage products to 220 V power supply may
cause faults such as overheating and equipment burning. For detailed input voltage AC please refer to
Specification(Rated voltage ±10%).If the operating voltage is too low or too high, a suitable automatic voltage
stabilizer must be installed for cooperative use.
Please place the equipment stably and avoid shaking.
Do not place the equipment in a dangerous area, and do not operate the equipment near flammable items to
prevent explosion or fire accidents.

3. Precautions in Use
®The equipment temperature display value is the temperature at the temperature sensor in the freezer storage
chamber. There is a certain gap between the displayed temperature and the actual temperature at the center of the
equipment when the equipment just starts running, but as the equipment enters a stable state, the displayed temperature
will gradually approach the actual temperature.
®When the equipment is not used for a long time, the power supply shall be cut off.
®Before putting the items into the equipment, please confirm that the temperature in the freezer storage chamber has
reached the set value first, and then put the articles in batches. Every time you put in items, they shall not exceed 1/3 of
the inner volume of the freezer storage chamber so as to prevent excessive temperature rise.
®Please use a diluted neutral cleaner to clean the equipment, and do not use brushes, acid, gasoline, soap powder,
polishing agent or hot water to clean the equipment, otherwise the painted surface and plastic rubber parts may be
damaged. Be careful not to wipe plastic rubber parts with volatile solvents such as gasoline.

®The equipment is an item storage equipment, which cannot be used for routine production operations. It is
strictly forbidden to put too many items which are relatively hot into the equipment at one time, otherwise
the compressor will run for a long time, and be burned due to high temperature. Items must be put in
batches, so as to ensure that the Refrigerator is cooled step by step until the temperature required for
storing items is reached.
®Do not change the set temperature frequently in a short time, otherwise the expected setting effect may not
be achieved due to the large temperature inertia; Ensure that there is a certain air circulation space around
the cabinet when putting in items, especially do not block the temperature sensor in the cabinet (for
collecting the temperature of the cabinet), otherwise it will affect the stability and accurate control of the
temperature in the cabinet!
®Electrical appliances without production license shall not be used inside the equipment.
®Due to the refrigeration inertia, there is a certain difference between the actual display temperature and the
set temperature of the equipment, which is a normal phenomenon.
®Items shall not be placed directly at the bottom of the Refrigerator, but on the bottom shelf, otherwise the
refrigeration effect of the equipment will be affected.
®A special person shall be responsible for checking and recording the running status of the equipment every
day (record and check once every 2-4 hours). In case of failure or shutdown, the temperature in the
Refrigerator will rise. If it cannot be repaired in a short time, please take out the stored items and transfer
them to a place that meets the temperature requirements for storage to avoid damage to the items.
®When putting in items, if the moisture content of the items is too much or too little, it will affect the humidity
change in the cabinet, so it is best to keep the items sealed; The humidity of the working environment will
affect the change of humidity in the cabinet, especially if the door is opened too frequently and the door is
not closed properly.
®Before putting items into the equipment, it shall be confirmed in advance whether the temperature range of
the equipment meets the temperature requirement of the items, so as to avoid damage to stored items due
to the difference between the settable temperature of the equipment and the required temperature of the
items. Please pay attention not to block the air outlet and air inlet when putting items into the equipment.
Notes:
Warning:
4.5 Operation after Power Failure
