Characteristics of HEAT mode operation
Mechanism and capacity of HEAT mode operation
■ Mechanism
• The unit draws heat from the cold outside air, transfers it to indoors and heats the room. As a characteristic of heat pump system, the
heating capacity reduces when the outside air temperature gets colder.
• It may take some time to supply hot air after turning on the air-conditioner.
• If the outside temperature becomes extremely low, it would be better to use an additional source of heating.
Defrosting
If the outside temperature becomes low and humidity is high, the heat exchanger in the outdoor unit may frost over, which prevents
efficient heating.
If this happens, the automatic defrost function is activated and during defrosting the heating operation stops for 5 to 15 minutes
during defrosting.
• Both indoor and outdoor fans stop and the RUN light blinks slowly (1.5 sec. ON, 0.5 sec. OFF) during defrosting.
• The outdoor unit may give off some steam during defrosting. This is to help the defrosting process and is not a defect.
• The HEAT operation resumes as soon as defrosting has been completed.

changes as follows:
Change on AIRFLOW (UP/DOWN) mode.
(Flap stopped)
(Swing)
NOTE FOR HEATING OPERATION
• When operation starts, the flap direction is fixed at the horizontal position in order to avoid cold draft, and return to the set the position that was set
after the warm air supply is starting.
• The flap direction will be controlled to the horizontal position when the room temperature reaches the set temperature and compressor stops or when
defrosting is in operation.
• The airflow direction cannot be set during the period mentioned above. Change the airflow direction settings after the warm air is supplied and the
flap goes to the set position.
MEMORY FLAP (FLAP STOPPED)
When you press the AIRFLOW button once while the flap is operating, it stops swinging at the
position. Since this angle is memorized in the microcomputer, the flap will automatically be set
at this angle when the next operation is started.
• Recommended angle of the flap when stopping
WARNING
• Do not expose directly to airflow from the air-conditioner for a long time.
CAUTION
• When in COOL or DRY operation, do not operate for a long period with the
airflow blowing straight down. Otherwise, condensation may appear on
the outlet grill and drip down.
• Do not try to adjust the flaps by hand, as the control angle may change or
the flap may not be closed completely.

• Do not put any obstruction in front of the indoor unit, preventing proper ventilation and functioning.
• Do not install the unit in any of the following places:
• Where there is a danger of leaking flammable gases.
• Where there is substantial splashing of oil.
• Malfunctioning due to corrosion may occur if the unit is installed in a spa where sulfide gases are generated, or in a seaside resort
exposed to sea breezes. Contact your dealer.
• The air-conditioner and remote control must be at least 1 metre away from a TV set or radio.
• Drain the dehumidified liquid from the indoor unit into a spot that drains well.
Pay attention to operating noises!
•
•
•
•
When you install the unit, take care to choose a place that can comfortably stand the weight of the unit and does not increase the operating noise
or vibration. If vibration is transmitted through the house, fix the unit with the aid of vibration-proof pads between the unit and the fittings.
Select a place where cold or hot air, operation noises from the indoor and outdoor units do not cause any inconvenience to your neighbours.
Do not leave any obstacles near the outlet and inlet of the outdoor unit. This may cause malfunctioning and increased operating noise.
If you hear an irregular noise during operation, contact your dealer.
Inspection and maintenance
Depending on operating environment, the inside of the air-conditioner may become dirty after a few year operations. This will reduce
performance. In addition to normal cleaning, we would recommend inspection and maintenance. (This may lead the air-conditioner to
having a longer life without any trouble.)
• Contact your dealer, or any distributor, for inspection and maintenance. (There will be a charge for this service).
• We would recommend inspection and maintenance to be carried out during the off-season.
• If the supply cord of this appliance is damaged, it must only be replaced by a repair shop appointed by the manufacturer, because
special purpose tools are required.

Troubleshooting
Please carry out the following checks before making a service call.
The air-conditioner does not work at all.
Has the power switch been turned off?
Has the timer been set in the “ON”
position?
Is there a power failure or a blown fuse?
Poor cooling or heating
Have you set the thermostat at a suitable
temperature?
Is the air filter clean? (Not clogged?)
Did you leave any doors or windows
open?
Poor cooling
Is there any direct sunlight entering the
room?
Is there a heat source in the room?
Are there too many people in the room?
If the air-conditioner does not operate properly after you have checked the above points, or if any doubt still exists after you have
consulted page 20, or if things happen as shown on page 21, switch off the power and contact your dealer.
