11. 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 insuffi cient, 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.)
[ ] 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, [
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
Heating
Indoor humidity
*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.
