Maintenance and Service
Indoor Unit
Before performing any maintenance, turn off the main power to the system, disconnect the circuit breaker and
unplug the power cord.
Clean the unit with a soft dry cloth. Do not use bleach or abrasives.
Never use any of these
• Water hotter than 40°C. It may cause deformation and discoloration.
• Volatile substances. They may damage the surface of the air conditioner.
Air Filters

cleaned once in every 2 weeks or more often if necessary. To
remove the filters see the self explanatory diagrams for each
model type. Clean the filters with a vacuum cleaner or warm
soapy water. If dirt is not easily removed, wash with a solution of
detergent in luke warm water. Dry well in shade after washing and
reinstall the filters back in place.
The plasma filters behind the air filter should be checked and
cleaned once in every 3 months or more often if necessary. To
remove the filters see the self explanatory diagrams for each
model type. Clean the filters with a vacuum cleaner. If it is dirty
wash it with water and dry well in shade an install back in place.

Maintenance and Service
Outdoor Unit
The heat exchanger coils and panel vents of the outdoor unit should be checked regularly.
If clogged with dirt or soot, the heat exchanger
and panel vents may be professionally steam cleaned.
Dirty or clogged coils will reduce the operating efficiency of the system and cause higher operating costs.
NOTE
Operation Tips!
Do not overcool the room.
This is not good for the health and
wastes electricity.
Keep blinds or curtains
closed.
Do not let direct sunshine enter
the room when the air conditioner
is in operation.
Keep the room temperature
uniform.
Adjust the vertical and horizontal
airflow direction to ensure a
uniform temperature in the room.
Make sure that the
doors and windows
are shut thight.
Avoid opening doors and
windows as much as
possible to keep the cool
air in the room.
Clean the air filter
regularly.
Blockages in the air filter
reduce the airflow and
lower cooling and
dehumidifying effects.
Clean at least once every
two weeks.
Ventilate the room
occasionally.
Since windows are kept
closed, it is a good idea
to open them and
ventilate the room now
and ten.
Use high fan speed
for effective and fast
cooling.
The unit gives its rated
cooling capacity when the
fan speed is high.

Troubleshooting Tips! Save time and money!
Maintenance and Service
The following table shows a series of seeming malfunctions.
Please check the following items before calling the Authorized Technical Service.
WHAT HAPPENS REASON
After a stop, the air conditioner does
not restarts immediately.
(RUNNING Indicator is illuminating).
• Restart is stopped for 3 minutes after shut down to protect the Unit.
Odor is sent out. • Air blown out during operation may smell. This is the smell of tobacco
or cosmetics sticked to the Unit.
• If the Unit is operated for a long period of time with the high humidity,
moisture may form on the air outlet grilles and drip down.
Remote control signals are not
received.
Moisture may form on the air outlet
grilles.
• This phenomenon sometimes occurs when the temperature and
humidity of the room are very high, but it will disappear with the lowering
of the temperature and humidity.
Air is not blown out at starting of
Heating operation.
• Air blow is stopped to prevent blowing out of cold air until the indoor
heat exchanger is warmed (2 to 5 min.).
(HOT KEEP)
Air is not blown out at DRY operation.
• When outdoor temperature is low and humidity is high, the Unit
sometimes performs defrosting automatically. Please wait. During
defrosting, water or steam are raising from the Outdoor Unit.
Mist is blown out at COOL operation.
• Remote control signals may not be received when signal receiver on
the air conditioner body is exposed to direct sunlight or strong lighting.
In that case, interrupt the sunlight or darken the lighting.
Following symptoms are not air conditioner's troubles
The Unit will not stop blowing out
the air immediately after shut down
at COOL operation.
• Because the Unit is doing mould proong operation and indoor fan
motor runs at Low speed. The louver will not close down until after 30
seconds.
Air is not blown out for 6 to 12 min.,
at HEATING operation.
• Indoor fan is sometimes stopped to prevent vapor of dehumidied
moisture and save energy.
Noise is heard
cracking sound. • This is caused by the refrigerant that is circulating inside the Unit.
Noise is heard cracking sound.
After a power stoppage or after
disconnecting the power supply
plug.
• This is caused by heat expansion or contraction of plastics.
Operation cannot be restarted even
if the power is recovered.
• The memory circuit of the microcomputer is cleared. Operate the
remote controller again to restart the operation.
•Three-minute protection timer incorporated in the microcomputer
actuates automatically. Except that power is connected, this function
does not actuate.
Not operate.
Please wait for
3 minutes.
