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.

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.
