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.

The room temperature is checked
60 minutes before the ON time.
Depending on the temperature at
that time, the operation starts 5 to
60 minutes before the timer is at
ON.
• The function is available for both
COOL and HEAT operation

adjusted after a while, ensuring that the room is not too cold during cooling or
too warm during heating.
• During cooling : The preset temperature is lowered by 1°C at the start of
SLEEP operation (when the timer is set). After that, the temperature goes
up by 1°C every an hour to become 1°C higher than the present
temperature.
• During heating: The preset temperature is lowered by 1°C at the start of
SLEEP operation (when the timer is set). After that the temperature becomes 3°C lower in an hour and 6°C lower in two hours than the present
temperature.

Proper installation
Suitable installation position
• 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?
Have you set the thermostat at a
suitable temperature?

Poor cooling or heating
Is the air filter clean? (Not
clogged?)
Poor cooling
Is there a heat source in the
room?
Is there a power failure or a
blown fuse?
Did you leave any doors or
windows open?
Are there too many people in
the room?
If the air-conditioner does not operate properly after you have checked
the left points, or if any doubt still
exists after you have consulted page
19, or if things happen as shown on
page 20, switch off the power and
contact your dealer.
An alternative refrigerant (R410A) is used in this air-conditioner. When asking your
dealer for service or inspection and maintenance, explain the dealer about it.

When outdoor temperature is low and humidity is high, the unit sometimes performs defrosting automatically. Please wait. During defrosting, water or steam may escape from the outdoor unit.
The indoor fan may stop to prevent re-evaporation of dehumified
moisture and to save energy.
This may occur if the room's temperature and humidity are very high.
It disappears as soon as the temperature and humidity decrease.
Air blown out during operation may smell. This is caused by tobacco
or cosmetics adhering to the unit.
This is caused by refrigerating liquid moving within the unit.
You hear a slight cracking sound.
You hear a hissing or clicking sound.
After a power cut, the unit does not restart even if power has been
restored.
Remote control signals are not received.
Moisture may form on the air outlet grills.
Whistling noise is heard from the outdoor unit.

About the Multiple Air-conditioner
Simultaneous Operation
• The air-conditioners cannot be in different operating modes at the same time, such as one unit being in the “Cool” mode and one unit being in
the “Heat” mode.
• When conducting different operations, the air-conditioner that was operated first will be given priority, so the air-conditioner that is operated
after that will conduct air blowing operation.
• When you want to give priority to the air-conditioner that was started later, either stop the air-conditioner that has priority or cause the
operation type of the unit operated first to match that of the unit operated second.
Automatic Operation
• When the remote control operation switch is in the “Auto” mode the air-conditioner automatically selects either “Cool,” “Dry,” or “Heat” when
operation is started depending on the room temperature.
• During simultaneous operation of air-conditioner units, operation modes may be automatically changed in response to the temperatures of the
individual rooms; this will result in the operation of the outdoor unit being stopped. In such a case, COOL or HEAT mode should be used
instead of AUTO. (This is only relevant when more than one air-conditioner unit is being used.)
Refrigerant (oil) recovery operation
• If the all of the indoor units are not operated at the same time for an extended period, the cooling or heating performance may temporarily
decrease. This is in order to control the recovery of the refrigerant (oil) in the stopped indoor unit(s). At this time, the sound of refrigerant
flowing may be heard from the stopped indoor unit(s).
