5. 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.
When dry mode starts, the set temperature changes.
■
When dry mode starts, the set temperature automatically changes to
the optimum initial set temperature.
6. Trouble Shooting
► 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 122°F), as this may warp them.
• Make sure that the air filters are always installed. Operating the unit with-
out air filters can cause malfunction.
• 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.
► Filter removal
Caution:
• In removing the filter, precautions must be taken to protect your eyes from
dust. Also, if you have to climb up on a stool to do the job, be careful not
to fall.
• When the filter is removed, do not touch the metallic parts inside the in-
door unit, otherwise injury may result.
