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

If the back holder 

is not needed

 

to prop 

up

 

the unit:

Finishing the pipe and cable connections 
before mount the indoor unit on the wall.
If the inst

a

llation height is limited, 5cm from 

the ceiling is allowable, but this can lower

 

product performance. To ensure enough

 

space to install and remove the top air filter,

 

keep at least 10cm or more from the ceiling.

 

 

T

he back holder 

is needed 

to prop up the 

unit:

 

If connecting pipe and cable with front 

panel

 

open, the minimum distance from 

ceiling is 22cm or more, if connecting pipe 
and cable without front panel(remove it) , the 
minimum distance from ceiling is 11cm or 
more.

 

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. 


 

Refer to the following diagram to ensure 

proper distance from walls and ceiling:

NOTE:

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

 

 

screws.  Make sure that mounting plate is flat 
against the wall. 

 

12cm (4.72in)

or more

2.3m (90.55in) or more

12cm (4.72in)

or more

Distance from ceiling is determinded 
by the installation method.

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.
