3.2 Attach mounting plate to wall
• The mounting plate is the device on which you
will mount the indoor unit.
1. Remove the screw that attaches the mounting plate to
the back of the indoor unit.
2. Place the mounting plate against the wall in a location
that meets the standards in the Select Installation Location
step. (See Mounting Plate Dimensions for detailed
information on mounting plate sizes.)
3. Drill holes for mounting screws in places that:
• have studs and can support the weight of the unit.
• correspond to screw holes in the mounting plate.
4. Secure the mounting plate to the wall with the screws
provided.
5. Make sure that mounting plate is flat against the wall.
• Mounting plate dimensions
Different models have different mounting plates. In order
to ensure that you have ample room to mount the indoor
unit, the diagrams to the right show different types of
mounting plates along with the following dimensions:
1. Width of mounting plate
2. Height of mounting plate
3. Width of indoor unit relative to plate
4. Height of indoor unit relative to plate
5. Recommended position of wall hole (both to the left
and right of mounting plate)
6. Relative distances between screw holes

3.3 Drill wall hole for connective piping
You must drill a hole in the wall for refrigerant piping, the
drainage pipe, and the signal 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.
2. Using a 65mm (2.5in) or 90mm(3.54in) (depending on
models )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 (0.2-0.27in). This will ensure proper
water drainage.
