• Clean off any oil stains or finger marks using a neutral household de-
tergent (such as dishwashing liquid or laundry detergent).
Caution:
Never use gasoline, benzene, thinner, scouring powder or any type
of non-neutral detergent, as these substances may damage the

When the is displayed on the
Main display in the Full mode, the
system is centrally controlled and
the filter sign cannot be reset.
If two or more indoor units are connected, filter cleaning timing for
each unit may be different, depending on the filter type.
The icon will appear when the filter on the main unit is due for
cleaning.
When the filter sign is reset, the cumulative operation time of all units
will be reset.
The icon is scheduled to appear after a certain duration of
operation, based on the premise that the indoor units are installed in
a space with ordinary air quality. Depending on the air quality, the filter
may require more frequent cleaning.
The cumulative time at which filter needs cleaning depends on the
model.

6. Care and Cleaning
Having trouble? Here is the solution. (Unit is operating normally.)
Air conditioner does not heat or cool well. ■Clean the filter. (Airflow is reduced when the filter is dirty or clogged.)
■Check the temperature adjustment and adjust the set temperature.
■Make sure that there is plenty of space around the outdoor unit. Is the
indoor unit air intake or outlet blocked?
■Has a door or window been left open?
When heating operation starts, warm air does not blow from the indoor
unit soon.
■Warm air does not blow until the indoor unit has sufficiently warmed
up.
During heating mode, the air conditioner stops before the set room tem-
perature is reached.
■When the outdoor temperature is low and the humidity is high, frost
may form on the outdoor unit. If this occurs, the outdoor unit performs
a defrosting operation. Normal operation should begin after approxi-
mately 10 minutes.

►Cleaning the filters
• Clean the filters using a vacuum cleaner. If you do not have a vacuum
cleaner, tap the filters against a solid object to knock off dirt and dust.
• If the filters are especially dirty, wash them in lukewarm water. Take
care to rinse off any detergent thoroughly and allow the filters to dry
completely before putting them back into the unit.
Caution:
• Do not dry the filters in direct sunlight or by using a heat source,
such as an electric heater: this may warp them.
• Do not wash the filters in hot water (above 50°C, 122°F), as this
may warp them.
• Make sure that the air filters are always installed. Operating the
unit without air filters can cause malfunction
