; maximum temperature 32

; ideal temperature

~25

; if necessary, please use the air conditioning system.

2.

Ambient humidity: less than 80% RH. If maximum working temperature is 32

,

the ambient humidity should be less than 57% RH.

3.

Avoid a lot of dust.

4.

Avoid mechanical swing or vibration.

5.

Altitude of the working position: less than 2000m.

6.

Input voltage: 220V~±10%.

* Notes:
1. The low-temperature freezer is relatively sensitive to ambient temperature, and
therefore it cannot operate normally if it is installed in any environment other than the
above-mentioned. In this case, please change the environment and then use the freezer.
2. It is prohibited to install the freezer in the open air. If the freezer is exposed to rain,
electric leakage or electric shock may occur.

Installation location

For normal operation and optimum performance, the freezer’s installation location
should meet the following requirements:
1.

The freezer must not be installed in a narrow and enclosed space. The door body
of the room where the freezer is installed must not be smaller and lower than the
freezer and must ensure normal pass-through of the freezer to avoid difficulty in
repair in case of any fault; otherwise the freezer cannot be restored in time,
resulting in deterioration of the articles stored in the freezer.

2.

At least 30cm should be reserved around the freezer for ventilation and heat dispersion.

3.

The freezer must be installed on flat floor.

4.

The freezer must be installed in a well-ventilated place without direct sunlight.

5.

The freezer should not share a socket with any other device. Ensure firm
connection between the plug and the socket.

6.

Do not twist or press the power cord.

7.

If the power cord needs to be extended, the extension cord must be of 220V~ and 15A.

8.

Please check the working voltage before use and consider using a voltage
stabilizer of 3kw and above in those areas with unstable voltage to ensure normal
input voltage within 220V~±10%.

9.

The freezer must be grounded reliably.

10. If the power socket is equipped with ground wire, please check it for reliable

grounding before use.

If the power socket is not equipped with ground wire, be sure to ask a qualified
technician to install proper ground wire.

2.

Adjust the legs

Clockwise turn the adjustable legs to extend them out and rest on the floor. Make

Please use a power socket with ground wire. If the power socket is not grounded,

be sure to ask a qualified technician to install proper ground wire.

Never ground the freezer through gas pipe, water pipe, telephone line or lighting

arrester, etc.; otherwise electric shock may occur.

The power socket must be accessible after installation in order to disconnect the

power cord from the power socket in an emergency.

The freezer’s air vent must not be covered by anything.

When use the freezer for the first time, please follow the steps:
1.

After installation, be sure to leave the freezer still for at least 24 hours before
turning it on.

2.

When the freezer is empty, connect the power cord to a special socket of proper
specifications.

3.

Turn on the rechargeable battery switch (it can be seen from the freezer’s back)
on the electric cabinet of compressor compartment at the top of freezer’s back. If
the switch is not turned on, low battery charge alarm will be given at the time of
test.

4.

When alarm sound is heard, please press the “Cancel buzz” key to stop buzz.

5.

Set the desired temperature: turn on the freezer without putting anything in the
freezer and observe the freezer for normal start and stop at least 24 hours. If so,
it means that the freezer’s performance is normal.

6.

After confirming normal performance, put articles to be stored in the freezer.
