2、 It is not recommended to use the air conditioner fresh air alone; if the air conditioner fresh air function is required, the windows and skylight exhaust fans must be opened simultaneously, which is conducive to the rapid circulation of fresh air inside the compartment and the air conditioner, and to avoid the spread of air pollution in the compartment.

3、 Disinfect the air duct and return air port in accordance with the bus.

4、 If you need to use the fresh air function of the air conditioner to ventilate the compartment, please do the following:
