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.
Drill a Hole in the Wall
- Drill the piping hole with a ø65mm hole core
drill. Drill the piping hole at either the right or
the left with the hole slightly slanted to the
outdoor side.
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.

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
1
Firmly hold copper pipe in a bar with the
dimension shown in below table.
2
Carry out flaring work with the flaring tool.
Check
1
Compare the flared work with the figure
by.
2
If a flared section is defective, cut it off
and do flaring work again.
Connecting the Piping
1
Pull the cover at the bottom of the indoor
unit. Pull the cover

2
Remove the cover from the indoor unit.

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.
Piping
1
Insert the connecting cable through the
bottom side of indoor unit and connect the
cable (You can see detail contents in
'Connecting the cables' section)

3
Tape the tubing pipe, drain hose and the
connection cable. Be sure that the drain
hose is located at the lowest side of the
bundle. Locating at the upper side can
cause overflow from the drain pan through
the inside of the unit.
