Air-conditioner operable temperature setting
■Use within the following operational range. Operating outside of this range may result in the protection devices being activated,
preventing the unit from working.
Cooling operation Heating operation
Outside temperature Approximately -15 °C to 46 °C Approximately -15 to 24 °C
Inside temperature Approximately 18 to 32 °C Approximately 15 to 30 °C
Below approximately 80%
The long-term use of the unit with a humidity level
Inside humidity
exceeding 80% may result in condensation forming —
on the surface of the indoor unit, leading to water drips.
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.
Press the FAN SPEED button
Set the fan speed as preferred.

Proper installation
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.
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.
