Stop the air conditioner before cleaning the element.
Articulate the machine fully to the right before replacing the air
filter element.

loosen knob (2), and open cover (3).

3. Direct dry compressed air (less than 0.69 MPa) to the ele-
ment from inside along its folds, then direct it from outside

removed with compressed air, or if it has been used for 1
year.
