When it is not going to be used for

a long time.

When the air conditioner is to

be used again.

Operate the air conditioner on Air circulation mode for 2 to 3 hours.

• This will dry out the internal parts.

Ventilate the room

occasionally.

Since windows are kept closed, it is a good idea to open them and ventilate the room now and then.
