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 operated 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 (v) are applicable only to "INVERTER MODEL".
l
When using a multi-type air conditioner, the multiple
indoor units can be operated simultaneously, but when
two or more indoor units of the same group are operated
simultaneously, 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 one 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.
l
Seasonal and outdoor temperature conditions, the
structure of the rooms and the number of persons present
may also result in differences of operating effi ciency.
We recommend 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.
l
lf you discover that one 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.
l
v
Operation cannot be done in the following different
operating modes.
If the indoor unit is instructed to do an operating mode
that it cannot perform,
controller display and the unit will go into the standby
mode.
Heating mode and cooling mode (or dry mode)
Heating mode and fan mode
Notice
Instructions relating to heating (*) are applicable only to "HEAT & COOL MODEL" (Reverse Cycle).
l
* During use of the heating mode, the outdoor unit will
occasionally 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.

v
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 indoor 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, will be shown on the remote
controller display and it would go into standby mode.
Indoor unit (B) would continue to operate in heating
mode.
l
* During use of the heating mode, the top of the indoor
unit may become warm, but this is due to the fact that
coolant is circulated through the indoor unit even when
it is stopped; it is not a malfunction.
