OPERATING TIPS
Multi-type Air conditioner
In the case of the indoor unit which 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 simul-
taneously, 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 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,
the OPERATION indicator lamp (green) for indoor unit (A)
would begin to 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 coolant 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 two or more
indoor units of the same group are operated simultaneously,
the heating and cooling ef 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.
●
Seasonal and outdoor temperature conditions, the structure
of the rooms and the number of persons present may also
result in differences of operating ef ciency. We recommend
that you try various operating patterns in order to con 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 one or more units delivers a low level of cool-
ing or heating during simultaneous operation, we recommend
that you stop simultaneous operation of the multiple units.
●
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, the OPERATION indicator lamp (green)
on the indoor unit will 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 defrost-
ing, 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 automatically
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) operation at
the new time setting. In the event that this kind of timer fault oc-
curs, the TIMER Indicator Lamp will 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 Controller
to resume operation.
