By the way, I just read this sa manual hehe.

Dehumidifying
Set the air flow selector to a desired air
flow selector position, the temperature
selector to the desired temperature position
(other than “OFF”) and the blower
speed selector to the desired blower speed
position. Also select “FRESH AIR”.

NOTE:
Because the air conditioning system dehumidifies
the air, turning it on will help keep
the windows clear
