dirty, soak a cloth in water-diluted neutral detergent, squeeze it well and wipe the
panel clean. Wipe it with another dry cloth.
E.g., at the end of the season.
▪ Let the indoor units run in fan only operation for about half a day in order to dry

person to clean air filters and casings of the indoor unit. Maintenance tips and
procedures for cleaning are provided in the installation/operation manuals of
