l If anything abnormal happens (such as burning smell), please power off the unit and cut off
the main power supply, and then immediately contact Gree appointed service center. If
abnormality keeps going, the unit might be damaged and lead to electric shock or fire.
l After connecting the power cord, please fix the electric box cover properly in order to avoid
accident.
l Be sure to use the exclusive accessory and part to prevent the water leakage, electric shock
and fire accidents.
l Make sure the unit can be earthed properly and soundly after plugging into the socket so as
to avoid electric shock. Please do not connect the ground wire to gas pipe, water pipe,
lightning rod or telephone line.
l The leakage circuit breaker must be installed. If not, it may cause electric shock or Fire.
l If refrigerant leakage happens during installation, please ventilate immediately. Poisonous
gas will emerge if the refrigerant gas meets fire.
l Refrigerant gas is heavier than air and oxygen, especially in the basement. A large amount
of refrigerant leakage will cause the decrease in oxygen and then cause suffocation, which
will affect the health of people.
l After all installations are completed, check whether there's refrigerant leakage.
l Do not install the unit in a flammable place. Otherwise, it will cause an explosion and affect
the health of people.
l Disposal of packaging, transportation materials and other parts must comply with the
relevant regulations of the local country.
NOTES!
l Before installation, please check if the power supply is in accordance with the requirements
specified on the nameplate. And also take care of the power safety.
l Turn off the unit after it runs at least five minutes; otherwise it will influence oil return of the
compressor.
l Electrify the unit 2 hours before operation. Please switch on for 2 hours before operation. Do
not cut off the power when 24 hours short-time halting (to protect the compressor).
l The air conditioner should be grounded, and the power outlet must be equipped with a
ground wire to ensure that the air conditioner is effectively grounded through the power
socket to avoid the risk of electric shock.
l Under cooling mode, please don't set the room temperature too low.
l When the air conditioner is installed in a small room, take the necessary measures to avoid
the concentration of the refrigerant exceeding the limit value for safety.
l When the external temperature is decreased, the heating performance of the unit will be
decreased. If so, please use another heating device for heating at the same time. (When you
use a heating device with open fire in the same room, please always open the door or
window to keep the air circulation and avoid the lack of oxygen in the room.) Please do not
put the heating device with open fire at the air outlet, or put it under the air conditioner.
