INSTALLATION MANUAL
4. INDOOR UNIT INSTALLATION
Refer to the following diagram to ensure proper distance from walls and ceiling:
12 cm (4,75 in)
4.2 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 sleeve anchors provided. Then secure the mounting plate to the wall by tightening the
screws directly into the clip anchors.
4.3 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. The wall hole should
have a 65mm (2.5in) diameter at least, and at a slightly lower angle to facilitate drainage.
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. (See Fig. 3.2)
3. Place the protective wall cuff in the hole. This protects the edges of the hole and will helpseal it when
you finish the installation process.
CAUTION
When drilling the wall hole, make sure to avoid wires, plumbing, and other sensitive components.
