2. Put strainers into warm water with neutral detergent (about 40℃) and clean up, and after that dry in shade place.
3. Install strainers to the original position in the direction
4. Process of taking out strainers: first take out strainer 1 and then strainer 2; process of installing strainers: first install strainer 2 and then strainer 1.

Postseason storage

When the air conditioner is out of season or not used for long time, corresponding maintenance measures should be taken.

• Drain all water in water pan from outlet (water can be poured out by slowly leaning the body backward during drainage), and adjust operating mode to FAN mode, and then press SPEED for 5s till fan works, keep this operating mode for 2~3h. This method can dry inside of the body and prevent mildew.
• Turn off the air conditioner and pull out power plug.
• Wind up, fasten and put away power line.
• Remove exhaust pipe and keep properly.
• Set the air conditioner into plastic bag and put it in a dry place.
