OPERATING TIPS
Multi-type Air conditioner
This indoor unit can be connected to a multi-type outdoor unit. The multi-type air conditioner allows multiple indoor units to be oper-
ated in multiple locations. The indoor units may be operated simultaneously, in accordance with their respective output.
●
Operation can be done in the following different operating
modes.
Cooling mode and dry mode
Cooling mode and fan mode
Dry mode and fan mode
●
The operating mode (heating mode or cooling (dry) mode)
of the outdoor unit will be determined by the operating
mode of the indoor unit that was operated fi rst. If the in-
door unit was started in fan mode, the operating mode of
the outdoor unit will not be determined.
For example, if indoor unit (A) was started in fan mode and
then indoor unit (B) was then operated in heating mode,
indoor unit (A) would temporarily start operation in fan
mode but when indoor unit (B) started operating in heating
mode, the OPERATION indicator lamp (green) for indoor
unit (A) would begin to fl ash (1 second on, 1 second off)
and it would go into standby mode. Indoor unit (B) would
continue to operate in heating mode.
●
During use of the heating mode, the top of the indoor unit
may become warm, but this is due to the fact that cool-
ant is circulated through the indoor unit even when it is
stopped; it is not a malfunction.
Notice
Simultaneous Use of Multiple Units
●
When using a multi-type air conditioner, the multiple indoor
units can be operated simultaneously, but when 2 or more
indoor units of the same group are operated simultane-
ously, the heating and cooling effi ciency will be less than
when a single indoor unit is used alone. Accordingly, when
you wish to use more than 1 indoor unit for cooling at the
same time, the use should be concentrated at night and
other times when less output is required. In the same way,
when multiple units are used simultaneously for heating,
it is recommended that they be used in conjunction with
other auxiliary space heaters, as required.
●
Seasonal and outdoor temperature conditions, the struc-
ture of the rooms and the number of persons present may
also result in differences of operating effi ciency. We rec-
ommend that you try various operating patterns in order to
confi rm the level of heating and cooling output provided by
your units, and use the units in the way that best matches
your family’s lifestyle.
●
If you discover that 1 or more units delivers a low level
of cooling or heating during simultaneous operation, we
recommend that you stop simultaneous operation of the
multiple units.
●
Operation cannot be done in the following different operat-
ing modes.
If the indoor unit is instructed to do an operating mode that
it cannot perform, the OPERATION indicator lamp (green)
on the indoor unit will fl ash (1 second on, 1 second off)
and the unit will go into the standby mode.
Heating mode and cooling mode (or dry mode)
Heating mode and fan mode
●
During use of the heating mode, the outdoor unit will occa-
sionally commence the defrost operation for brief periods.
During the defrosting operation, if the user sets the indoor
unit for heating again, the defrosting mode will continue,
and the heating operation will begin after completion of
defrosting, with the result that some time may be required
before warm air is emitted.
AUTO Restart
In Event of Power Interruption
●
The power supply to the air conditioner is stopped by a
power interruption. The air conditioner will then restart auto-
matically in its previous mode when the power is restored.
●
If a power interruption occurs during TIMER operation, the
timer will be reset and the indoor unit will begin (or stop) op-
eration at the new time setting. In the event that this kind of
timer fault occurs, the TIMER Indicator Lamp will fl ash (see
Page. 3).
●
Use of other electrical appliances (electric shaver, etc.) or
nearby use of a wireless radio transmitter may cause the air
conditioner to malfunction. In this event, temporarily turn off
the circuit breaker, turn it on and then use the Remote Con-
troller to resume operation.
