10. GENERAL INFORMATION

■ Inverter
On start-up, the air conditioner will operate at maximum capacity to
bring the room quickly down to desired temperature.
Once the room temperature reaches to the set temperature, the air
conditioner will reduce its capacity and energy usage to the minimum
capacity and input ratings.
■ 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.
Consult with your installation technician to ensure the unit is correctly
sized for the room space required.
Heat-pump air conditioners heat your entire room by recirculating air
throughout the room, with the result that some time may be required
after fi rst starting the air conditioner until the room is heated.
■ 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, an automatic defrosting 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, disconnect the power supply once.
Then reconnect it, 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).
