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 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.
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
(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. 3.2)
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, make sure to
avoid wires, plumbing, and other sensitive
components.

- Be extra careful not to damage dent or deform the pipe while cutting this will drastically reduce the heating efficiency of the unit 26
- Do not deform pipe while cutting 26
- Place flare nuts on both ends of pipe make sure they are facing in the right direction because you can t put them on or change their direction after flaring see 26
- Proper flaring is essential to achieve an airtight seal 26

- Step 4 connect pipes 27
- Turn the handle of the flaring tool clockwise until the pipe is fully flared 27
- When bending connective refrigerant piping the minimum bending radius is 10cm see 27
- When connecting refrigerant pipes be careful not to use excessive torque or to deform the piping in any way you should first connect the low pressure pipe then the high pressure pipe 27
- Instructions for connecting piping to outdoor unit 28
- Loosen the flaring nut slightly then tighten again 28
- Repeat steps 3 to 6 for the remaining pipe 28
- Torque from tightening the flare nut can snap off other parts of valve 28
- Use spanner to grip main body of valve 28
- Valve cover 28
- While firmly gripping the body of the valve use a torque wrench to tighten the flare nut according to the correct torque values 28
