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.

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.
