Step 4 - Drill a Wall Hole for Connective Pipe

1. Determine the location of the wall hole based on the location of the
outdoor unit.
2. Use a 2.5in (65mm) or 3.54in (90mm) hole saw, drill a hole in the wall.
Ensure the hole is drilled at a slight downward angle, so that the
outdoor end of the hole is lower than the indoor end by about 0.5in
(12mm). This ensures proper water drainage.
3. Place the protective wall cuff in the hole. This protects the edges of the
hole and helps seal it when you finish the installation.
CAUTION
EQUIPMENT DAMAGE HAZARD
When drilling the wall hole, make sure to avoid wires and plumbing.
