8 Maintenance and Care 

Regular check, maintenance and care can extend unit’s service life. Please have specialized 

person in charge of the management of air conditioners. 

8.1 Outdoor Heat Exchanger 

Outdoor heat exchanger shall be cleaned regularly, which is at least once every two months. You 

can use a dust catcher with nylon brush to clean away the dust on the heat exchanger. If compressed 
air source is available, it also can be used to clean the heat exchanger. Do not clean it with water. 

8.2 Drain Pipe 

Please check regularly whether drain pipe is blocked or not. Make sure condensate can be 

drained out smoothly. 

8.3 Notice before Seasonal Use 

(1)  Check whether air inlets and air outlets of indoor and outdoor units are blocked. 
(2)  Check whether ground connection is reliable or not. 
(3)  Check whether batteries in the remote controller are replaced or not. 
(4)  Check whether air filter is properly installed. 
(5)  If unit starts up after not operating for a long time, it should be power on 8 hours before 

operation starts so as to preheat the outdoor compressor. 

(6)  Check whether outdoor unit is securely installed. If there is any problem, please contact 

Gree authorized service center.
