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 briefl y (maximum of 15 minutes.)

[I] 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:

*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.

OPTIONAL PARTS

12.1. Wired remote controller
The optional wired remote controller can be used.
You can use wired and wireless remote controller together.
However, some functions of the wireless remote controller are restricted.
If you set the restricted functions, beeping sound will be heard, [l], [ ] and [ ] indicator on the indoor unit will blink.
