Indoor Unit Installation: 4.3 Drill Through-Hole In Outdoor Wall
Drilling Hole Through Wall To Exterior:
It is necessary to drill a 3" hole in the wall to pass refrigerant piping, drain tube and signal cable through wall to
exterior.
Determine the location of the 3" hole based on the location of the mounting plate. Refer to Fig. 4.3 on this page
for accurate hole location based on unit size. Note: Bottom of 3" hole should not drop below bottom edge of wall
mount bracket. Dropping the hole lower than the bottom edge will result in the indoor unit not completely cover-
ing the hole. (If rerouting the exit position of the refrigerant piping, drain tube and signal cable differently from
pre-set factory orientation, ensure 3" wall hole is covered by unit where possible).
Using a 3" hole saw, drill hole from interior wall through to exterior of building. Drill hole at slight downward angle
towards the outside. See Fig. 4.3b on this page. Note: If installing through concrete or brick, special drill & drill
bits will be required.
