Fixing Installation Plate
The wall you select should be strong and solid
enough to prevent vibration
1
Mount the installation plate on the wall with type
"A" screws. If mounting the unit on a concrete
wall, use anchor bolts.
- Mount the installation plate horizontally by
aligning the centerline using Horizontal meter.
2
Measure the wall and mark the centerline.
It is also important to use caution concern-
ing the location of the installation plate.
Routing of the wiring to power outlets is
through the walls typically. Drilling the hole
through the wall for piping connections
must be done safely.

Burrs removal
1
Completely remove all burrs from the cut
cross section of pipe/tube.
2
While removing burrs put the end of the
copper tube/pipe in a downward direction
while removing burrs location is also
changed in order to avoid dropping burrs
into the tubing.
Putting nut on
- Remove flare nuts attached to indoor and
outdoor unit, then put them on pipe/tube
having completed burr removal.
(not possible to put them on after finishing
flare work)

Flaring Work
Main cause for gas leakage is due to defect of
flaring work. Carry out correct flaring work in
the following procedure.
Cut the pipes and the cable
1
Use the piping kit accessory or the pipes
purchased locally.
2
Measure the distance between the indoor
and the outdoor unit.
3
Cut the pipes a little longer than measured
distance.
4
Cut the cable 1.5 m longer than the pipe
length.

2
Push the 6 point hook to assemble chassis
cover. Push the chassis cover ① → ②.
NOTE
To protect the chassis cover bended,
assembly chassis cover correctly.
Installation of Indoor Unit
1
Hook the indoor unit onto the upper por-
tion of the installation plate.( engage the
three hooks at the top of the indoor unit
with the upper edge of the installation
plate) Ensure that the hooks are properly
seated on the installation plate by moving
it left and right

2
Unlock the tubing holder from the chassis
and mount between the chassis and instal-
lation plate in order to separate the bottom
side of the indoor unit from the wall.
* The feature can be changed according to the
type of model.
