•Ambient temperature: 16 ° C to 32 ° C, and the optimal temperature range is 18 ° C to 25 ° C. Use 
air conditioning system when necessary.
•Ambient humidity: less than 85% Rh.
•Avoid large amounts of dust.
•Avoid mechanical swing or vibration.
•Altitude of the working position of refrigerator: below 2000m.
•Input voltage: rated voltage ±10%.
•Overvoltage category:The transient state is Category II facility.
•Pollution Degree:2
In order  to  ensure normal  operation of  the  refrigerator and  obtain  the  optimal  performance, the 
installation site of the refrigerator shall meet the following conditions:
•It cannot be installed in narrow and enclosed space, and the door of the installation room shall not 
be smaller than this product. It should be at least ensured that the refrigerator can be moved in and 
out normally, so as to avoid maintenance diculties in case of fault; otherwise the goods stored in 
the refrigerator may be spoiled due to delayed repair of the refrigerator.
•The oor of the installation site must be solid and at.
•Do not share the same socket with plugs of other devices. The plug shall be securely connected to 
the socket.
•Do not twist or stress the power cord.
•If the power cord needs to be lengthened, the cross-sectional area of the extension part shall not 
be less than 2 mm
2
 and the length shall not be longer than 3 m.
•Please check the working voltage before use. For areas with unstable voltage, a stabilizer that is 
suitable for motor load may be adopted for voltage regulating, thus ensuring that the normal input 
voltage maintains at rated voltage ±10% and the stabilizer power is greater than 4000W.
•The refrigerator shall be reliably grounded.
•If the power socket is equipped with a grounding wire, check if the grounding condition is good 
before use.
•If the outlet is not equipped with any grounding wire, be sure to install the grounding  wire by a 
professional technician.
•Do not ground the  refrigerator through the gas pipe, power hose, telephone  line or 
lightning rod, otherwise may cause electric shock.
•After installation, the power plug must be accessible to facilitate unplugging the power 
cord in time in case of emergency. Do not cover the vents of the refrigerator with any 
objects.
•Since the refrigerator is sensitive to ambient temperature, it cannot operate normally 
if is installed in an environment other than the above. Please use it after improving the 
environment.
•It is prohibited to install the refrigerator outdoors. If the refrigerator gets wet in the rain, 
it may cause electric leakage or electric shock.
•Keep it away from radiation area and avoid using radiation sensitive equipment near it.
