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 to 46 °C Approximately -15 to 24 °C

Approximately 10 to 30 °C Inside temperature Approximately 18 to 32 °C

Inside humidity

Below approximately 80%

The long-term use of the unit with a humidity level exceeding 80% may result in condensation forming on the surface of the indoor unit, leading to water drops.

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 effi cient 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.
