4.3 Preparation Before Use
Warning: Don't put the plastic bags within the reach of children, so as to prevent suffocation accidents.
2. Under no-load condition, connect the power cord to a special outlet with appropriate specifications.
4. Check whether the operating temperature of the equipment reaches the required value, observe the
normal start and stop of the equipment for more than 24 hours, and put a small amount of items in the
equipment after confirming the normal performance.
6. Try not to open the door during cooling, otherwise the temperature will rise.
1. After the equipment is placed, leveled and cleaned, it shall stand for more than 24 hours, and then
power it on to ensure the normal operation of the equipment.
1. Remove the outer packaging of all products (including the protective foam in the packaging box)
2. Inventory of accessories: Please check the accessories and materials according to the packing list.
3. Cleaning: Clean the product once before use.
4.4 First Power-on
When using the equipment for the first time, please follow these steps:
3. After powering on, turn on the power switch of the equipment.
5. Please store items in batches, with the items not exceeding 1/3 of the caibinet body volume each
time. Ensure that the equipment is running properly after shutdown for more than 12 hours before
putting in the next batch of items).
4.5 Operation after Power Failure
2. Once the equipment is powered off, it requires 5 minutes before it can be switched on again, so as to
avoid damaging the compressor.
3. We guarantee the normal operation of this equipment under certain conditions, but we are not
responsible for any loss or damage of stored items after power failure.
® The transportation and movement of equipment is realized by casters.
® 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 storage
chamber 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.
1. The equipment has a memory function for the set value. When the power is restored after power
failure, the equipment will continue to operate before power failure.
® 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.
® 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 storage chamber 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 body.
® Electrical appliances without production license shall not be used inside the equipment.
® 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.
® 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 equipment, but on the bottom shelf, otherwise the
refrigeration effect of the equipment will be affected.
Attention: Since the ambient temperature has great influence on the equipment, if the above
environmental requirements cannot be met, the equipment may not run normally. Please improve the
environment before using the equipment; The equipment is operated intermittently.
Notes:
Warning: Children are not allowed to play with this equipment as a game prop, otherwise the injury or
loss caused therefrom will be at their own risk.

3. Precautions in Use
◆ Before putting the items into the equipment, please confirm that the temperature in the 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 equipment so as to prevent excessive temperature rise.
◆ The cabinet body is provided with a test hole so as to lead out the test line from the cabinet during the
test. After the test line is led out, it is necessary to plug the test hole with thermal insulation material
again, otherwise the temperature inside the equipment may not reach the set value, and condensation
will appear around the outside of the through hole.
◆ The equipment temperature display value is the temperature at the temperature sensor in the 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.
◆ 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.
◆ When the equipment is not used for a long time, the power supply shall be cut off.
◆ After a period of operation, a layer of frost will form on the inner wall and inner door of the cabinet body.
Before defrosting, please take out the frozen items in the equipment and put them in an environment
suitable for their storage, so as to prevent the item damage due to the temperature rise in the
equipment during defrosting.
4.1 Installation Environment
ò Relative humidity: ≦80%RH.
ò Ambient temperature: 16°C ~ 32°C, the most ideal temperature is 18°C ~ 25°C, and the air
conditioning system shall be used when necessary.
ò Avoid the existence of a large amount of dust.
ò Avoid rocking or shaking the equipment.
