may warp them.
• Make sure that the air lters are always installed. Operating the unit
without air lters can cause malfunction.

• Before you start cleaning, stop operation and turn OFF the power
supply.
• Indoor units are equipped with lters to remove the dust of suckedin air. Clean the lters using the methods shown in the following
sketches.
