Airflow Direction Auto-control
The left and right airflow direction louver can be adjusted manually.
Airflow direction manual control
When the airflow direction set button is pressed,the automatic airflow is released and the
airflow direction louver moves up and down as shown in thetable below. The louver can
be stopped by releasing the button at the desired position.
When the remote control is used to stop the operation,the discharge vent is closed with
airflow direction louver.
When set at airflow direction auto-control with remote control,the louver swings up and down as shown in the table below.
The louver does not swing when the indoor fan stops during operation.
When stop the unit with remote control,the discharge vent is closed with the louver.
When temperature of indoor heat exchanger reaches 38
during heating mode operation, if temperature falls to 35 ,airflow
direction will change from the lower limit to horizontal.
Angles Of Airflow Direction Louver
Notes:
In heating mode operation
1.
Airflow direction is automatically adjusted to horizontal direction when the temperature of indoor heat exchanger is low and it will
be automatically adjusted downward while the indoor temperature rises.
2.
The airflow direction is automatically adjusted to horizontal direction when temperature of indoor heat exchanger is low .While
temperature of indoor heat temperature rises ,the airflow direction is automatically adjusted to the place set by the remote control.

Airflow direction manual control:
In cooling or soft dry mode operation
If the compressor continues to operate for 60 minutes ,and the louver direction is at No 5,the fan speed is below Med, the intake
air temperature is below 29
and continues to change between 2
for 30 minutes ,the louver direction will be at No 2 in order
to prevent dew around the discharge vent.
