Instructions relating to heating (*) are applicable only to “HEAT & COOL MODEL” (Reverse Cycle).

*

  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

*

  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.

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.

Instructions relating to inverter (

) are applicable only to “INVERTER MODEL”.

❖ 

  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.

Simultaneous Use of Multiple Units

  ●

 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 ef

fi

 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 ef

fi

 ciency. We rec-

ommend that you try various operating patterns in order to 
con

fi

 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 

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.

 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.
