10Maintenance
WARNING
Cleaning the air filter and other parts of the air filter involves dangerous work in high places, so be sure
to have a qualified installer or qualified service person to do it.
Do not attempt it by yourself.
After the cooling or dry auto (cooling) operation has finished, the dry operation is performed and the fan
starts running. When cleaning the unit, stop the drying operation forcibly and turn off the circuit breaker
to avoid electric shock.
Cleaning air filters
Clogged air filters will reduce the cooling and heating performance.
(1) If “ ” is displayed on the remote controller, clean the air filters.
(2) When the cleaning of air filters has been completed, push button.
“”disappears.
When the unit will not be used for a long time
1. Perform the fan operation for a couple of hours to dry inside.
2. Press on the remote controller to stop running, and turn off the circuit breaker.
3. Clean the air filters and reinstall them.
Before the cooling season
Clean the drain pan

sure to clean the drain pan before the cooling season.)
(1)
(2)
Check periodically
• If the unit is used for a long time, parts may deteriorate and cause malfunction or bad drainage of dehumidified water
depending on the heat, humidity, or dust.
• In addition to the usual maintenance, it is recommended that you have the unit checked and maintained by the dealer where
you purchased it.
NOTE
For environmental conservation, it is strongly recommended that the indoor and outdoor units of the air conditioner in
use be cleaned and maintained regularly to ensure efficient operation of the air conditioner.
When the air conditioner is operated for a long time, periodic maintenance (once a year) is recommended.
Furthermore, regularly check the outdoor unit for rust and scratches, and remove them or apply rustproof treatment, if
necessary.
As a general rule, when an indoor unit is operated for 8 hours or more daily, clean the indoor unit and outdoor unit at
least once every 3 months. Ask a professional for this cleaning / maintenance work.
Such maintenance can extend the life of the product though it involves the owner’s expense.
Failure to clean the indoor and outdoor units regularly will result in poor performance, freezing, water leakage, and even
compressor failure.

11Troubleshooting
Check the points described below before requesting repair.
If there is something unusual even after checking the above, stop running the unit, turn off the circuit breaker, and inform the
dealer where you purchased the product of the product number and symptom. Do not attempt to repair the unit by yourself as
doing so is dangerous. If the check indicator ( , , , etc.) is displayed on the remote controller LCD, inform the dealer
of its content as well.
If any of the following occur, stop running the unit immediately, turn off the circuit breaker, and contact the dealer where you
purchased the product.
• The switch does not work properly.
• The circuit breaker often blows out.
• You unintentionally put a foreign object or water inside.
• The unit cannot be run even after the cause of the protective device activation is removed.
• Other unusual conditions are found.
Symptom Cause
It is not a malfunction.
Outdoor unit
• White, misty, cold air or water comes out
• Sometimes the noise of air leaking is heard.
• A noise is heard when the power is turned
on.
• The fan of the outdoor unit is automatically stopped and
defrosting is performed.
• The solenoid valve works when defrosting starts or stops.
• The outdoor unit is preparing for running.
Indoor unit
• Sometimes a swishing is heard.
• A clacking sound is heard.
• Discharged air smells unusual.

unit operation is stopped.
• When the unit starts running, during operation, or
immediately after the unit stops running, a sound such as
water flowing may be heard, or the operation sound may
become louder for a couple of minutes immediately after
the unit starts running. This is the sound of the refrigerant
flowing or the dehumidifier draining.
• This is a sound generated when the heat exchanger, etc.
expands and contracts slightly due to temperature
change.
• Various smells from the walls, carpet, clothes, cigarette,
cosmetics, etc. adhere to the air conditioner.
• The fan keeps running to self clean operation the heat
exchanger during drying.
• The unit does not run • Has a blackout occurred?
• Has the circuit breaker blown?
• Has the protective device been activated? (The operation
indicator and on the remote controller are blinking.)
Check again.
The room does not cool down or warm up.
• Is the air intake or discharge of the outdoor unit clogged?
• Is a door or window open?
• Is the air filter clogged with dust?
• Is the air volume set to “Low”? Or is the operation mode
set to “Fan”?
• Is the setup temperature appropriate?

12Operations and performance
▼Check before running
• Check whether the earth wire is cut or disconnected.
• Check whether the air filter is installed.
• Turn on the circuit breaker 12 hours or more before starting
operation.
▼3 minutes protection function
3-minutes protection function prevents the air conditioner
from starting for initial 3 minutes after the main power switch
/ circuit breaker is turned on for re-starting the air conditioner.
▼Power failure
Power failure during operation will stop the unit completely.
• To restart the operation, push the ON / OFF button on the
remote controller.
• Lightning or a wireless car telephone operating nearby
may cause the unit to malfunction. Turn off the main power
switch or circuit breaker and then turn them on again. Push
the ON / OFF button on the remote controller to restart.
▼Defrosting operation
If the outdoor unit is frosted during the heating operation,
defrosting starts automatically (for approximately 2 to 10
minutes) to maintain the heating capacity.
• The fans in both indoor and outdoor units will stop during
the defrosting operation.
• During the defrosting operation, the defrosted water will be
drained from the bottom plate of the outdoor unit.
▼Heating capacity
In the heating operation, the heat is absorbed from the
outside and brought into the room. This way of heating is
called heat pump system. When the outside temperature is
too low, it is recommended to use another heating apparatus
in combination with the air conditioner.
▼Protective device
• Stops operation when the air-conditioner is overloaded.
• If the protective device is activated, the unit stops running,
and the operation indicator and check indicator on the
remote controller blink.
▼If the protective device is activated
• Turn off the circuit breaker and perform a checkup.
Continued running may cause a malfunction.
• Check whether the air filter is installed. If not, the heat
exchanger may be clogged with dust and water leakage
may occur.
▼During cooling
• The air intake or discharge of the outdoor unit is clogged.
• Strong wind continuously blows against the discharge of
the outdoor unit.
▼During heating
• The air filter is clogged with a large amount of dust.
• The air intake or discharge of the indoor unit is clogged.
▼Do not turn off the circuit breaker
During the air-conditioning season, leave the circuit breaker
turned on, and use the ON / OFF key on the remote
controller.
▼Attention to snowfall and freeze on the
outdoor unit
• In snowy areas, the air intake and air discharge of the
outdoor unit are often covered with snow or frozen up.
If snow or freeze on the outdoor unit is left as it is, it may
cause machine failure or poor warming.
• In cold areas, pay attention to the drain hose so that it
perfectly drains water without water remaining inside for
freeze prevention. If water freezes in the drain hose or
inside the outdoor unit, it may cause machine failure or
poor warming.
▼Air conditioner operating conditions
For proper performance, operate the air conditioner under the following temperature conditions:
If air conditioner is used outside of the above conditions, safety protection may work.
Cooling operation
Outdoor temperature : –15 °C to 43 °C (Dry bulb temp.)
Room temperature : 21 °C to 32 °C (Dry bulb temp.), 15 °C to 24 °C (Wet bulb temp.)
[CAUTION] Room relative humidity – less than 80 %. If the air conditioner operates in excess of this
figure, the surface of the air conditioner may cause dewing.
Heating operation Outdoor temperature : –15 °C to 15 °C (Wet bulb temp.)
Room temperature : 15 °C to 28 °C (Dry bulb temp.)
13Installation
Do not install the air conditioner in the following places
• Do not install the air conditioner in any place within 1 m from a TV, stereo, or radio set. If the unit is installed in such place,
noise transmitted from the air conditioner affects the operation of these appliances.
• Do not install the air conditioner near a high frequency appliance (sewing machine or massager for business use, etc.),
otherwise the air conditioner may malfunction.
• Do not install the air conditioner in locations where iron or other metal dust is present. If iron or other metal dust adheres to
or collects on the interior of the air conditioner, it may spontaneously combust and start a fire.
• Do not install the air conditioner in a humid or oily place, or in a place where steam, soot, or corrosive gas is generated.
• Do not install the air conditioner in a salty place such as seaside area.
• Do not install the air conditioner in a place where a great deal of machine oil is used.
• Do not install the air conditioner in a place where it is usually exposed to strong wind such as in seaside area.
• Do not install the air conditioner in a place where sulfureous gas generated such as in a spa.
• Do not install the air conditioner in a vessel or mobile crane.
• Do not install the air conditioner in an acidic or alkaline atmosphere (in a hot-spring area or near a chemicals factory, or in a
place subject to combustion emissions). Corrosion may be generated on the aluminum fin and copper pipe of the heat
exchanger.
• Do not install the air conditioner near an obstacle (air vent, lighting equipment, etc.) that disturbs discharge air. (Turbulent
airflow may reduce the performance or disable devices.)
• Do not use the air conditioner for special purposes such as preserving food, precision instruments, or art objects, or where
breeding animals or growing plants are kept.
(This may degrade the quality of preserved materials.)
• Do not install the air conditioner over an object that must not get wet. (Condensation may drop from the indoor unit at a
humidity of 80 % or more or when the drain port is clogged.)
• Do not install the air conditioner in a place where an organic solvent is used.
• Do not install the air conditioner near a door or window subject to humid outside air.
Condensation may form on the air conditioner.
• Do not install the air conditioner in a place where special spray is used frequently.
Be careful with noise or vibrations
• Do not install the air conditioner in a place where noise by outdoor unit or hot air from its air discharge annoys your neighbors.
• Install the air conditioner on a solid and stable foundation so that it prevents transmission of resonating, operation noise and
vibration.
• If one indoor unit is operating, some sound may be audible from other indoor units that are not operating.
