Performance of the refrigerator is degraded if the operational conditions are
beyond the specifications mentioned above.
The unit should be installed indoors. Electric leakage or shock is possible if the
unit gets wet by rainwater.
The installation site shall meet following requirements for normal operation and best performance of
refrigerator:
Do not install the refrigerator in a narrow and confined space as heat may be trapped to increase
ambient temperature. Additionally, the unit should not be installed in a space where the entry door
way is low to prevent an easy maneuver of the unit for maintenance and operation.
The floor for the installation site should be solid and flat. It should also be well ventilated and free
from direct sunshine.
The power outlet for the refrigerator must be a dedicated power outlet. The power plug must be
plugged in to the outlet securely.
Do not twist or jam the power cord.
If the power cord needs to be extended, the cross section area of the conductor in the extended
line should be no less than 2 squared millimeters and no longer than 3 meter.
Inspect the operating voltage range before operation. If the voltage supply is unstable, install a
voltage stabilizer of 4000 W or greater to ensure the supply voltage is within 10% of the rated
voltage supply.
The refrigerator must be grounded reliably.
Check the integrity of the socket ground before power up. If it is not grounded appropriately,
repair the wiring before installing the unit.
Do not ground the refrigerator through gas lines, water lines, telephone lines, or lighting rods as
these devices may cause electric shock and danger.

.
Avoid excessive dust.
Avoid mechanical vibration.
The refrigerator shall operate at an altitude lower than 2000m.
Input voltage: no greater than ±10% of rated voltage.
Installation site
The power plug and outlet should be located in a place where they can be
accessed easily and immediately in case of an emergency. Air vents must be
free of obstruction.
The power plug can be accessed after installation to ensure the power line can
be pulled out in a timely manner in emergency cases. The air vent shall free from
barriers.
