5. Caring for the machine
Always have filter maintenance performed by a service person.
Before performing maintenance, turn the power supply OFF.
Caution:
• Before you start cleaning, stop operation and turn OFF the power
supply. Remember that the fan is rotating inside at high speed, posing
a serious risk of injury.
• Indoor units are equipped with filters to remove the dust of sucked-
in air. Clean the filters following the procedures on the below. (The
standard filter should normally be cleaned once a month.)
• The life of the filter depends on where the unit is installed and how it is
operated.
• When removing the filter, precautions must be taken to protect your
eyes from dust. Also, if you have to climb up on a stool or ladder to do
the job,
be careful not to fall.
How to clean
• A washable air filter is provided with the unit.
• Clear dust away lightly or clean it up with a vacuum cleaner. In the case
of severe clogging, wash the filter in lukewarm water mixed with dissolved
neutral detergent or water, and then rinse off the detergent completely. After
washing, dry it and reinstall.
Caution:
• Do not dry the filter by exposing it to direct sunlight or warming it
using fire, etc. Doing so can result in the deformation of the filter.
• Washing it in hot water (more than 50 °C [122 °F]) can also result in
deformation.
Caution:
Never pour water or flammable sprays onto the air conditioner. Cleaning
using these methods can result in the failure of the air conditioner, electric
shock, or fire.
Removal and replacement of filter
• Unscrew the two thumb knobs on the panel stamped "filter" tilt forward and
pull the panel out. Grasp the edge of the filter and slide out. Re-install in
reverse.
