OPERATING TIPS
Multi-type Air conditioner
In the case of the indoor unit which can be connected to a
m
ulti-type outdoor unit :
The
m
ulti-type air conditioner allows
m
ultiple indoor units to be operated in
m
ultiple locations. The indoor units
m
ay be
operated si
m
ultaneously, in accordance with their respective output.
●
Operation can be done in the following different operat-
ing
m
odes.
Cooling
m
ode and dry
m
ode
Cooling
m
ode and fan
m
ode
Dry
m
ode and fan
m
ode
●
The operating
m
ode (heating
m
ode or cooling (dry)
m
ode) of the outdoor unit will be deter
m
ined by the op-
erating
m
ode of the indoor unit that was operated first.
If the indoor unit was started in fan
m
ode, the operating
m
ode of the outdoor unit will not be deter
m
ined.
For exa
m
ple, if indoor unit (A) was started in fan
m
ode
and then indoor unit (B) was then operated in heating
m
ode, indoor unit (A) would te
m
porarily start opera-
tion in fan
m
ode but when indoor unit (B) started oper-
ating in heating
m
ode, the OPERATION indicator la
m
p
(green) for indoor unit (A) would begin to flash (1 sec-
ond on, 1 second off) and it would go into standby
m
ode.
Indoor unit (B) would continue to operate in heating
m
ode.
●
During use of the heating
m
ode, the top of the indoor
unit
m
ay beco
m
e war
m
, but this is due to the fact that
coolant is circulated through the indoor unit even when
it is stopped; it is not a
m
alfunction.
Notice
Si
m
ultaneous Use of Multiple Units
●
When using a
m
ulti-type air conditioner, the
m
ultiple
indoor units can be operated si
m
ultaneously, but when
two or
m
ore indoor units of the sa
m
e group are oper-
ated si
m
ultaneously, the heating and cooling efficiency
will be less than when a single indoor unit is used alone.
Accordingly, when you wish to use
m
ore than one in-
door unit for cooling at the sa
m
e ti
m
e, the use should
be concentrated at night and other ti
m
es when less out-
put is required. In the sa
m
e way, when
m
ultiple units
are used si
m
ultaneously for heating, it is reco
mm
ended
that they be used in conjunction with other auxiliary
space heaters, as required.
●
Seasonal and outdoor te
m
perature conditions, the struc-
ture of the roo
m
s and the nu
m
ber of persons present
m
ay also result in differences of operating efficiency.
We reco
mm
end that you try various operating patterns
in order to confir
m
the level of heating and cooling out-
put provided by your units, and use the units in the way
that best
m
atches your fa
m
ily’s lifestyle.
●
If you discover that one or
m
ore units delivers a low
level of cooling or heating during si
m
ultaneous
operation, we reco
mm
end that you stop si
m
ultaneous
operation of the
m
ultiple units.
●
Operation cannot be done in the following different op-
erating
m
odes.
If the indoor unit is instructed to do an operating
m
ode
that it cannot perfor
m
, the OPERATION indicator la
m
p
(green) on the indoor unit will flash (1 second on, 1 sec-
ond off) and the unit will go into the standby
m
ode.
Heating

ode (or dry
m
ode)
Heating
m
ode and fan
m
ode
●
During use of the heating
m
ode, the outdoor unit will
occasionally co
mm
ence the defrost operation for brief
periods. During the defrosting operation, if the user sets
the indoor unit for heating again, the defrosting
m
ode
will continue, and the heating operation will begin after
co
m
pletion of defrosting, with the result that so
m
e ti
m
e
m
ay be required before war
m
air is e
m
itted.
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
m
atically in its previous
m
ode when the power is
restored.
●
If a power interruption occurs during TIMER operation, the
ti
m
er will be reset and the indoor unit will begin (or stop)
operation at the new ti
m
e setting. In the event that this kind
of ti
m
er fault occurs, the TIMER Indicator La
m
p will flash
(see Page 3).
●
Use of other electrical appliances (electric shaver, etc.) or
nearby use of a wireless radio trans
m
itter
m
ay cause the
air conditioner to
m
alfunction. In this event, te
m
porarily
turn off the circuit breaker, turn it on and then use the
Re
m
ote Controller to resu
m
e operation.
