OPERATING TIPS
About Mode Operation
Heating: G Use to warm your room.
G When Heating mode is selected, the air conditioner will operate at very
low fan speed for about 3 to 5 minutes, after which it will switch to the
selected fan setting. This period of time is provided to allow the indoor
unit to warm up before beginning full operation.
G When the room temperature is very low, frost may form on the outside
unit, and its performance may be reduced. In order to remove such
frost, the unit will automatically enter the defrost cycle from time to
time. During Automatic Defrosting operation, the OPERATION indica-
tor Lamp will flash, and the heat operation will be interrupted.
G After the start of heating operation, it takes sometime before the room
gets warmer.
Cooling: G Use to cool your room.
G Use for gently cooling while dehumidifying your room.
Dry:
G You cannot heat the room during Dry mode.
G During Dry mode, the unit will operate at low speed; in order to adjust
room humidity, the indoor unit's fan may stop from time to time. Also,
the fan may operate at very low speed when adjusting room humidity.
G The fan speed cannot be changed manually when Dry mode has been
selected.
G Use to circulate the air throughout your room.
Fan:
AUTO Restart
In Event of Power Interruption
G Should the power supply to the air conditioner be inter-
rupted by a power failure, the air conditioner will restart
automatically in the previously selected mode once the
power is restored.
G 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 indicator lamp will flash.
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 (
G 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 oper-
ated simultaneously, the heating and cooling efficiency
will be less than when a single indoor unit is used alone.
Accordingly, when you wish to use more than one in-
door unit for cooling at the same time, the use should
be concentrated at night and other times when less out-
put 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.
G Seasonal and outdoor temperature conditions, the struc-
ture of the rooms and the number of persons present
may also result in differences of operating efficiency.
We recommend that you try various operating patterns
in order to confirm the level of heating and cooling out-
put provided by your units, and use the units in the way
that best matches your family's lifestyle.

) are applicable only to "INVERTER MODEL".
During Heating mode:
Set the thermostat to a temperature set-
ting that is higher than the current room
temperature. The Heating mode will not
operate if the thermostat is set lower than
the actual room temperature.
During Cooling/Dry mode:
Set the thermostat to a temperature set-
ting that is lower than the current room
temperature. The Cooling and Dry modes
will not operate if the thermostat is set
higher than the actual room temperature
(in Cooling mode, the fan alone will ope-
rate).
During Fan mode:
You can not use the unit to heat and cool
your room.
G 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
disconnect the power supply plug, reconnect it, and then
use the remote control unit to resume operation.
G If you discover that one or more units delivers a low
level of cooling or heating during simultaneous opera-
tion, we recommend that you stop simultaneous opera-
tion of the multiple units.
G Operation cannot be done in the following different op-
❖
erating modes.
If the indoor unit is instructed to do an operating mode
that it cannot perform, the OPERATION indicator lamp
on the indoor unit will flash (1 second on, 1 second off)
and the unit will go into the standby mode.
