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 briey (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.

Multi-type air conditioner

This indoor unit can be connected to a multi-type outdoor unit, and used as a multi-type air conditioner that allows multiple indoor units to be operated in multiple locations. The indoor units may be operated simultaneously, in accordance with their respective output.

Simultaneous use of multiple indoor units

• If 2 or more indoor units are operated simultaneously, the heating and cooling efciency will be less than the efciency in

single use of the indoor unit. Combined use of other auxiliary heating or cooling apparatus is recommended.

• Following combinations cannot be performed when multiple indoor units are operated:

- HEAT mode and COOL mode (or DRY mode)

- HEAT mode and FAN mode

The indoor unit operated afterward stops and the OPERA-

TION indicator ashes.

• The operating mode (HEAT, COOL, and DRY) of the outdoor

unit is determined by the operating mode of the indoor unit that

is operated rst. If the indoor unit is started in FAN mode, the

operating mode of the outdoor unit cannot be determined. For example, if indoor unit (A) is started in FAN mode and then indoor unit (B) is operated in HEAT mode, indoor unit (A) will temporarily start operation in FAN mode but when indoor unit (B) started operation in HEAT mode, the OPERATION indicator (green) on the indoor unit (A) will begin to blink (1 second on, 1 second off) and go into standby mode. Indoor unit (B) will continue to operate in HEAT mode.

• In HEAT mode, the top of the indoor unit may become warm by emitted heat of circulated coolant through the indoor unit, even if the unit operation is stopped. This is not a malfunction.

Wired remote controller (option)

Optional wired remote controller can be used. You can use both wired and wireless remote controller simultaneously, but functions of the wireless remote controller will be limited. For wired remote controller functions, see the Operation manual for the wired remote controller. When the restricted functions on the wireless remote controller are selected, beeping sound will be heard, OPERATION, TIMER and the
