• The operation mode can also be set or changed when the
air-conditioner is not in operation.
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.
Outside temperature Approximately -15 to 46 °C
Inside temperature Approximately 18 to 32 °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.
