AIR CONDITIONER Wall Mounted Type
OPERATING MANUAL
General Informations on Operation
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 briey (maximum of 15 minutes.)
OPERATION 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, the TIMER indicator on the
indoor unit blinks to notify you that there has been a timer fault.
In such a case, reset the timer for your opportune time.
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.
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 insufcient, we recommend you to use
this air conditioner in conjunction with other kinds of heating
appliance.
Wired remote controller (option)
The optional wired remote controller can be used.
When you use remote controller, there are following different points
as compared with using wireless remote controller.
[The additional functions for wired remote controller]
• Temperature set back timer
And you can use both wired and wireless remote controller
simultaneously. (But function is limited.)
When the restricted functions on the remote controller are used,
beeping sound will be heard, OPERATION, TIMER and the
ECONOMY indicator of the indoor unit will ash.

Temperature and Humidity Range
Permissible ranges of temperature and humidity are as follows:
COOL/DRY Indoor temperature About 18 °C to 32 °C
Indoor humidity Below approximately 80%.
If the air conditioner is used continuously for many
hours, water may condense on the surface and drip.
HEAT Indoor temperature About 16 °C to 30 °C
If the unit is used under higher temperature conditions than those noted here, the automatic protection circuit may operate, interrupting the operation.
If the unit is used under lower temperature conditions than those noted here, the heat exchanger may freeze, causing water leakage or other mal-
function.
●
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.
