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
À
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 multy-type air conditioner that allows multiple
indoor units to be operated in multiple locations.
The indoor units may be operated simultaneously, in accor-
dance 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
À
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.
