Indoor Unit
If the split type Indoor unit is installed in a wall hav-
ing hole or opening near by or back side of the unit,
then the air from other side of the wall can come
inside the condition space through that hole/ open-
ing. That air can cause unwanted dew/ water
droplet formation when it comes in contact with
body of the indoor unit. So all hole or opening on
the wall must be blocked very well to avoid water
dropping from the body of the unit.
