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.

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
