12 | Indoor Unit Installation 

Refer to the following diagram to ensure proper distance from walls and ceiling:

 

 

Fig. 4.1 

 

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 
5mm-diameter (0.2in-diameter) holes in the wall and insert the wall 
anchors provided. Then 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 communication 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. 4.2 )

 

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.

 

 

CAUTION

 

When drilling the wall hole, protect the cable by using suitable material 
in the hole.
