GENERAL INFORMATION

Heating performance
This air conditioner operates on the heat-pump principle, absorbing heat from air outdoors and transferring that heat to the indoor unit. As a result, the operating performance is reduced as outdoor air temperature drops.

If you feel that the heating performance is insufficient, we recommend you to use this air conditioner in conjunction with other kinds of heating
appliance.

Automatic defrosting operation
When outdoor temperature is very low with high humidity, frost may form on the outdoor unit during the heating operation, and it could reduce the operating performance of the product.

For frost protection, a microcomputer-controlled automatic defrost function is equipped in this air conditioner.

If frost forms, the air conditioner will temporarily stop, and defrost circuit will operate briefly (maximum of 15 minutes.)

[

] indicator on the indoor unit blinks during this operation.

If frost forms on the outdoor unit after the Heating operation, the outdoor unit will stop automatically after it operates for a few minutes. Then the Automatic defrosting operation starts.

Auto-restart function
In event of power interruption such as a blackout, the air conditioner stops once. But it restarts automatically and performs previous operation when the power supply is resumed.

If any power interruption occurs after the timer is set, counting down of the timer will be reset.

After the power supply is resumed, [

] indicator on the indoor unit

blinks to notify you that there has been a timer fault. In such a case,

reset the clock and timer settings.

Malfunctions caused by other electrical devices
Use of other electrical appliances such as an electric shaver or nearby use of a wireless radio transmitter may cause the malfunction of the air conditioner.
If you encounter such a malfunction, turn off the circuit breaker once. Then turn it on again, and resume operation by using the remote controller.
Indoor unit temperature and humidity range
Permissible ranges of temperature and humidity are as follows:

Indoor temperature Cooling/Dry [°C] 18.0 to 30.0

Indoor humidity

Heating

[°C] 16.0 to 30.0 [%] 80 or less *1)

*1) If the air conditioner is used continuously for many hours, water may condense on the surface and drip.
· If the unit is operated under the conditions except the permissible temperature range, the air conditioner operation may stop because of the automatic protection circuit working.
· Depending on the operating conditions, the heat exchanger may freeze, causing water leakage or other malfunction (in the Cooling or Dry mode).
Other information
· Do not use the air conditioner for any purpose other than room cooling/dry, room heating or fan.
· For the permissible ranges of temperature and humidity for the outdoor unit, refer to the outdoor unit installation manual.
