Step 3: Drill wall hole for connective piping
Determine the location of the wall hole based on the position of the mounting plate. Refer to Mounting
Plate Dimensions.
Using a 65mm (2.Sin) or 90mm(3.54in) (depending on models )care 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.
Place the protective wall cuff in the hole. This protects the edges of the hole and will help seal it
when you finish the installation process.
CAUTION
When drilling the wall hole, make sure to avoid wires, plumbing, and other sensitive components.
MOUNTING PLATE DIMENSIONS
Different models have different mounting plates. For the different customization requirements, the
shape of the mounting plate may be slightly different. But the installation dimensions are the same
for the same size of indoor unit.
See Type A and Type B for example:
