Step 3: Drill wall hole for connective piping
You must drill a hole in the wall for refrigerant piping, the drainage pipe, and the
signal/power cable that will connect the indoor and outdoor units.
1. Determine the location of the wall hole based on the position of the mounting
plate. Refer to Mounting Plate Dimensions on the next page to help you
determine the optimal position. The wall hole should have a 65mm (2.5in)
diameter at least, and at a slightly lower angle to facilitate drainage.
2. Using a 65-mm (2.5in) core drill, drill a hole in the wall. Make sure that 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 5mm to 7mm (0.2-0.275in). This will
ensure proper water drainage. (See Fig. 4)
3. Place a protective wall sleeve (not included) in the hole. This protects the
edges of the hole and will help seal it when you fi nish the installation process.
CAUTION:

When drilling the wall hole, make sure to avoid wires,
plumbing, and other sensitive components.
