DISPOSAL

Fig. 1
IMPORTANT
Dirty fi lters cause condensation in the air conditioner which will contribute to
the growth of fungi such as mold. It is therefore recommended to clean air fi lters
every 2 weeks.
Before starting the operation, ensure that the horizontal vanes are in the closed
position. If operation starts when the horizontal vanes are in the open position,
they may not return to the correct position.

Important
 Clean the fi lters regularly for best performance and to
reduce power consumption.
 Dirty fi lters cause condensation in the air conditioner
which will contribute to the growth of fungi such as
mold. It is therefore recommended to clean air fi lters
every 2 weeks.

Important
 The surface of the indoor unit is easily scratched, so
never rub or hit the unit with something hard. Also,
when installing or removing the front panel, handle it
with care to prevent scratches on it.
 Do not use abrasive cleaner to prevent scratches on the
surface of the indoor unit.
 It is very easy to get fi ngerprints on the surface of the
indoor unit. When fi ngerprints are noticeable, gently
wipe them off with a soft dry cloth.
 When using a commercially available chemical impreg-
nated cloth, follow its instructions.
 Do not leave the front panel open for a prolonged time.
