When resetting “FILTER” display
When the [FILTER] button is pressed two times successively after
cleaning the filter, the display goes off and is reset.
Note:
zWhen two or more different types of indoor unit are controlled, the
cleaning period differs with the type of filter. When the master unit
cleaning period arrives, “FILTER” is displayed. When the filter display
goes off, the cumulative time is reset.
z“FILTER” indicates the cleaning period when the air conditioner was used
under general indoor air conditions by criteria time. Since the degree
of dirtiness depends on the environmental conditions, clean the filter
accordingly.
zThe filter cleaning period cumulative time differs with the model.
zThis indication is not available for wireless remote controller.
ŹCleaning 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.
Caution:
• Before you start cleaning, stop operation and turn OFF the power
supply.
• Indoor units are equipped with filters to remove the dust of sucked-
in air. Clean the filters using the methods shown in the following
sketches.

11. Troubleshooting
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
temperature 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
approximately 10 minutes.
Airflow up/down direction changes during operation or airflow up/down
direction cannot be set.
During cooling mode, the vanes automatically move to the horizontal
(down) position after 1 hour when the down (horizontal) airflow up/
down direction is selected. This is to prevent water from forming and
dripping from the vanes.
During heating mode, the vanes automatically move to the horizontal
airflow up/down direction when the airflow temperature is low or
during defrosting mode.
When the airflow up/down direction is changed, the vanes always move
up and down past the set position before finally stopping at the position.
When the airflow up/down direction is changed, the vanes move to the
set position after detecting the base position.
A flowing water sound or occasional hissing sound is heard. These sounds can be heard when refrigerant is flowing in the air
conditioner or when the refrigerant flow is changing.
A cracking or creaking sound is heard. These sounds can be heard when parts rub against each due to
expansion and contraction from temperature changes.
The room has an unpleasant odor. The indoor unit draws in air that contains gases produced from the
walls, carpeting, and furniture as well as odors trapped in clothing,
and then blows this air back into the room.
A white mist or vapor is emitted from the indoor unit. If the indoor temperature and the humidity are high, this condition may
occur when operation starts.
During defrosting mode, cool airflow may blow down and appear like a
mist.
Water or vapor is emitted from the outdoor unit. During cooling mode, water may form and drip from the cool pipes
and joints.
During heating mode, water may form and drip from the heat
exchanger.
During defrosting mode, water on the heat exchanger evaporates and
water vapor may be emitted.

Note: As an applicable humidity standard for both indoors and outdoors, we recommend use within a range of 30 - 80% relative humidity.
Warning:
If the air conditioner operates but does not cool or heat (depending on model) the room, consult your dealer since there may be a
refrigerant leak. Be sure to ask the service representative whether there is refrigerant leakage or not when repairs are carried out.
The refrigerant charged in the air conditioner is safe. Refrigerant normally does not leak, however, if refrigerant gas leaks indoors, and
comes into contact with the fire of a fan heater, space heater, stove, etc., harmful substances will be generated.
