If the split type Indoor unit is installed in a wall having 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 /
opening. 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.
