normally if it is installed in an environment other than the above. Please use it after
improving the environment.

•It is prohibited to install the freezer in the open air environment. When the freezer
gets wet in the rainwater, it may cause leakage of electricity or electric shock accident.

•Ambient temperature: 16°C to 32°C , 18°C to 25°C are optimal and air conditioning system is
required as necessary.

Ambient humidity: below 85%Rh.

Avoid excessive dust.

Avoid mechanical swing or vibration.

The freezer shall operate at an altitude 2,000 m.

Input voltage: within the range of 220-240V~.

For normal operation and optimum performance level of the freezer, its installation place shall
conform to the following conditions:

• It can not be installed in a narrow, small and airtight space, the door frame of the room for placing it
shall not be less than and lower than this product, and shall at least guarantee its normal passing in
and out so as to avoid any maintenance difﬁ culty and failure of in-time repair in occurence of machine

• If it is required to lengthen the power cord, the section area of the lengthened wire shall not be less
than 2mm

and the length shall not be longer than 3m.

• Ckeck tje operationg voltage before use, at the area where the voltage is not stable, use of a voltage
regulator suitable for the motor load shall be considered for voltage stabilization. So that the normal
input voltage is stabilized at 220-240V~, the power of the voltage regulator is greater than 2000W.

• The freezer shall be guaranteed with reliable earthing.

• If the power socket has earth wire, check if the earthing is good before use.

• The interior is used for storing ﬂ ammable and explosive reagents.

• The appliance is not suitable for use in explosion-hazard areas.

Cleaning and Maintenance

After under operation for a certain time, the frost will be formed on the inner wall of freezer, which
might affect the normal refrigerating effect if it is too thick, and might consume more energy.
Therefore, after a certain time of operation, when the thickness of frost reaches to 5mm around, you
should use the attached defrosting shovel to clean it according to the following steps
• Take out the articles kept in the bin and move to appropriate site;
• Switch off the power switch;
• Open the outer and inner doors for a while in order to defrost naturally;
• After frost melts well, discard the water from the drawers or drain it from the drainage hole;
• Dry the bottom of bin;
• Restart the equipment after the bin is cleaned well;
• Put all articles back in the bin that has already been cooled down.

• Do not use knife or screwdriver or similar tools with sharp edges to defrost.

• Defrosting should be carried out once per month, up to once per three months.
