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:

Good air circulation

Convenient drainage
Noise from the unit will not disturb other

people

Firm and solid—the location will not vibrate

Strong enough to support the weight of the

unit

A location at least one meter 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.

Step 2: Attach mounting plate to wall

The mounting plate is the device on which you

will mount the indoor unit.

Remove the screw that attaches the mounting

plate to the back of the indoor unit.

Secure the mounting plate to the wall with
the screws provided. Make sure that mounting
plate is flat against the wall.

12cm (4.75in)

or more

2.3m (90.55in) or more

12cm (4.75in)

or more

15cm (5.9in) or more

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

Determine the location of the wall hole based

on the position of the mounting plate. Refer

Mounting Plate Dimensions.

MOUNTING PLATE DIMENSIONS

Different models have different mounting plates.
For the different customization requirements, the
shape of the mounting plate may be slightly
different. But the installation dimensions are the
same for the same size of indoor unit.
See Type A and Type B for example:

Correct orientation of Mounting Plate

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
(0.2-0.275in). This will ensure proper water
drainage.

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.
