1. CAPACITY CONTROL
1-1 COOLING, HEATING, DRY CAPACITY CONTROL
Compressor frequency decides by capacity of an indoor unit, operation number of an indoor unit,
set temperature, room temperature and outside temperature.
When the air conditioner is set to the Auto mode by remote controller, operation starts in the optimum
mode from among the Heating, Cooling, Dry and Monitoring mode. During operation, the
optimum mode is automatically switched in accordance with temperature changes. The temperature
can be set between 18°C and 30°C in 1°C steps.
When operation starts, indoor fan and outdoor fan are operated for around 3 minutes.
Room temperature and outdoor temperature are sensed,
and the operation mode is selected in accordance with the table below. <Monitoring mode>
Cooling mode
25°C Heating mode
( Table 1 : Operation mode selection table )
Room temperature (TR)
TR> Ts + 2°C

The airflow can be switched in 5 steps such as Auto, Quiet, Lo, Me, Hi,
while the indoor fan only runs.
When Fan mode is set at (Auto), it operates on (Me) Fan Speed.
2. FAN OPERATION
3. COOLING OPERATION (Auto : Cooling)
Switch the airflow [Auto], and the indoor fan motor will run according to a room temperature,
as shown in Fig 3.
On the other hand, if switched in [Hi] [Quiet], the indoor motor will run at a constant airflow of [Cooling]
operation modes Quiet, Lo, Me, Hi.

5. HEATING OPERATION
Switch the airflow [Auto], and the indoor fan motor will run according to a room temperature,
as shown in Fig 5.
On the other hand, if switched in [Hi] [Quiet], the indoor motor will run at a constant airflow
of [Heat] operation modes Quiet, Lo, Me, Hi, as shown in Table 2.

Each time the button is pressed, the air direction range
will change as follow:
(Function Range)
(Table9 : Recommended Operation Range)
Use the air direction adjustments within the ranges shown above.
The vertical airflow direction is set automatically as shown, in accordance with the type of operation selected.
Cooling / Dry mode : Horizontal flow
Heating mode : Downward flow AS*G07/09/12: , AS*G18/24:
When the temperature of the air being blown out is low at the start of heating operation or during
defrosting, the airflow direction temporarily becomes to prevent cold air being blown onto the body.
During use of the Cooling and Dry modes, do not set the Air Flow Direction Louver in the Heating
range ( ) for long period of time, since water vapor many condense near the outlet louvers and
drop of water may drip from the air conditioner. During the Cooling and Dry modes, if the Air Flow
Direction Louvers are left in the heating range for around 30 minutes, they will automatically
return to position .
