GENERAL INFORMATION

• Heating performance
  This air conditioner operates on the heat-pump principle, absorbing heat from the 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 insuffi cient, we recommend you to use this air conditioner in conjunction with other kinds of heating appliances.

• Automatic defrosting operation
  When the 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, an 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.)
  [ ] 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 the event of a power interruption such as a blackout, the air conditioner stops once. But it restarts automatically and performs the previous operation when the power supply is resumed.
  If any power interruption occurs after the timer is set, the 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 the remote controller.

• Indoor unit temperature and humidity range
  Permissible ranges of temperature and humidity are as follows:Cooling/Dry mode| Outdoor temperature [°C]| -10 to 46
  ---|---|---
  Indoor temperature [°C]| 18 to 32
  Indoor humidity [%]| 80 or less* 1)
  Heating mode| Outdoor temperature [°C]| -15 to 24
  Indoor temperature [°C]| 16 to 30

*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 conditions except for 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.
