Installation Instructions – Indoor Unit
PRIOR TO INSTALLATION
Before installing the indoor unit, refer to the label on the
product box to make sure that the model number of the
indoor unit matches the model number of the outdoor
unit.
Step 1: Select installation location
Before installing the indoor unit, you must choose an
appropriate location. The following are standards that will
help you choose an appropriate location for the unit.
Proper installation locations meet the following
standards:
þGood air circulation
þConvenient drainage
þNoise from the unit will not disturb other people
þFirm and solid—the location will not vibrate
þStrong enough to support the weight of the unit
þA location at least one metre from all other electrical
devices (e.g., TV, radio, computer)
DO NOT install unit in the following locations:
Near any source of heat, steam, or combustible gas
Near flammable items such as curtains or clothing
Near any obstacle that might block air circulation
Near the doorway
In a location subject to direct sunlight
NOTE ABOUT WALL HOLE:
If there is no fixed refrigerant piping:
While choosing a location, be aware that you should
leave ample room for a wall hole (see Drill wall hole
for connective piping step) for the signal cable and
refrigerant piping that connect the indoor and outdoor
units. The default position for all piping is the right side of
the indoor unit (while facing the unit). However, the unit
can accommodate piping to both the left and right.
Refer to the following diagram to ensure proper
distance from walls and ceiling:

120 mm OR MORE 120 mm OR MORE
2300 mm OR MORE

Page 10
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 at against the wall.
NOTE FOR CONCRETE OR BRICK WALLS:
If the wall is made of brick, concrete, or similar material,
drill 5mm-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.
Correct orientation of Mounting Plate
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. The wall hole should have a 65mm
diameter at least, and at a slightly lower angle to facilitate
drainage.
2. Using a 65-mm 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. This will ensure proper
water drainage. (See Fig. 5.3)
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, make sure to avoid wires,
plumbing, and other sensitive components.
