Indoor Unit Installation
Refer to the following diagram to ensure proper distance from walls and ceiling:
Step 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.
NOTE FOR CONCRETE OR BRICK WALLS:
If the wall is made of brick, concrete, or similar
material, drill 0.2 in diameter (5 mm diameter)
holes in the wall and insert the sleeve anchors
provided. Secure the mounting plate to the
wall by tightening the screws directly into the
clip anchors.
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 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. Refer
to Fig. 4.3 wall hole diameter and install at a slight
angle to facilitate drainage.
2. Using a core drill [3.5 in (76.2 mm) for 24K & 36K
units, 2.5 in (65 mm) for all others], 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 0.2
to 0.275 in (5 mm-7 mm). This will ensure proper
water drainage. (See Fig. 4.2)
3. 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.
Fig. 4.1
CAUTION
When drilling the wall hole, be sure to avoid
wires, plumbing, and other sensitive
components.
