Mounting the Indoor Unit to the Installation Plate

The indoor unit can fall from the wall if it is not properly installed and secured to the installation plate.

Falling indoor units can cause bodily injury or death.

• To avoid a gap between the installation plate and the wall, ensure the screws are correctly

and fully secured.

• To prevent condensate from forming due to an inflow of outdoor air, before indoor unit installa-

tion is finished, completely seal the piping access hole in the wall.
