OPERATING TIPS

AUTO Restart

In Event of Power Interruption
Should the power supply to the air conditioner be inter-
●
rupted by a power failure, the air conditioner will restart au-
tomatically in the previously selected mode once the power
is restored.
Should a power failure occur during TIMER operation, the
●
timer will be reset and the unit will begin (or stop) operating
under the new timer setting. In this event, the TIMER indi-
cator lamp (orange) will fl ash.
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.
Simultaneous Use of Multiple Units
Instructions relating to inverter (
● When using a multi-type air conditioner, the multiple in-
door units can be operated simultaneously, but when 2 or
more indoor units of the same group are operated simul-
taneously, 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 heat-
ing, 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 fan mode
Simultaneous Multi Air Conditioner
This indoor unit can also be connected to a simultaneous multi connection that enables simultaneous operation of up to 3 indoor
units with connecting the outdoor unit by using a separation tube (twin or triple).
Note: Connectable type of the separation tube varies by model.
In simultaneous multi connection, all the indoor units perform simultaneous air conditioning controlled by one controller that is
specifi ed as the primary control unit.
For this unique characteristic of the simultaneous multi connection, some of the functions controlled by the controller that is specifi ed
as the secondary control unit are restricted.

) are applicable only to "INVERTER MODEL".
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 discon-
nect the power supply plug, reconnect it, and then use the
remote controller to resume operation.
❖
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 sec-
ond off) and it would go into standby mode. Indoor unit (B)
would continue to operate in heating mode.
