minutes.

- This is to protect the air conditioner. Wait until the air conditioner
begins operating.
Q

from the air conditioner.
A
- Condensation occurs when the
airflow from the air conditioner
cools the room air.
DRY
Q
- During soft dry mode operation the air conditioner
stops.
A
- Soft Dry Mode operation is a very gentle cooling
operation consisting primarily of dehumidifying. The
air conditioner may stop for approximately 6 minutes
in order to prevent overcooling. If the room
temperature rises again, the operation will
recommence.

operation. (Frost accumulates on the outdoor unit
when the outdoor temperature is low and humidity
is high.) Water comes out from the outdoor unit.
- A sound like water flowing can
be heard.
- This is the sound of refrigerant
flowing inside the air
conditioner unit.
