Keep the openings of the pipes covered with tapes etc. to prevent dust, sand, etc.
from entering them.
Secure using upper 2 screws for floor installations.
If possible, also attach two lower screws.
At first secure the installation board using 5 screws and the indoor unit using 2 screws.

If there is an obstacle such as a cable cover,
cut off the hatched part before installation.
Installation of Installation board
Look for the inside wall structures (Intersediats
support or pillar and finally install the unit after level
surface has been checked.)

Adjustment of the installation board in the horizontal
direction is to be conducted with five screws in a temporary
tightened state.

When practicing the half-console, make sure to fix the unit securely.

Adjust so the board will be level by turning the board with
the standard hole as the center.

Remove the flared nuts. (on both liquid and gas sides)

Install the removed flared nuts to the pipes to
be connected,then flared the pipes.
CAUTION
Do not apply refrigerating machine oil to the flared surface.
CAUTION
In case of faulty wiring connection, the indoor unit
stops, and then the run lamp turns on and the timer
lamp blinks.
CAUTION

During installation, do not lean on the control box or the display, as they
may be damaged.
 Pass the connecting wire securely through the wiring holder. If it passes
on the sensor, it may not detect suction temperature and/or humidity.
Use cables for interconnection wiring to avoid
loosening of the wires.

Use a flare tool designed for R410A or a conventional flare tool.
Please note that measurement B (protrusion from the flaring block) will vary depending
on the type of a flare tool in use.
If a coventional flare tool is used, please use a copper pipe gauge or a similar
instrument to check protrusion so that you can keep measurement B to a correct value.

Tighten the nuts to the following torque.
Liquid side (ø6.35) : 14.0 - 18.0 N·m (1.4 - 1.8 kgf·m)

Fitting
1 Do remove the air filter.
2 Cover the body with the front panel.
3 Fit the 6 latches in the lower section.
then 3 latches in the upper section.
4
Tighten the 5 set screws.
5
Fit the air filter.
6
Fit the air inlet panel.
 To close, attach the panel after pulling
the strings, hold the panel at both ends of
upper part to lower downward and push it
slightly until the latch works.
Preparation of indoor unit
1 Remove the fixing screw of clamp.
2
Connect the connecting wire securely to the terminal block.
1 ) Connect the connection wire securely to the terminal
block. If the wire is not affixed completely, contact will be
poor, and it is dangerous as the terminal block may heat
up and catch fire.
2 ) Take care not to confuse the terminal numbers for indoor
and outdoor connections.
3 Fix the connecting wire by wiring clamp.
4 Pass the connecting wire through the wiring holder.

Floor installation Wall installation
・ During the installation, do not lean on the control box or the display, as they may be damaged.
・
Install the indoor unit on flat wall. If improperly installed, it may cause abnormal noise and vibration. (Distortion on the wall shall be no larger than 3 mm.)

CAUTION
If heat insulation is insufficient, water leakage
may occur. In addition, the room temperature
sensor may give a false alert due to heat
radiation from the pipes.
 Cover the indoor unit’s flare-connected joints, after
they are checked for a gas leak, with an indoor unit
heat insulating material and then wrap them with a
tape with an attached pipe cover placed over the
heat insulating material’s slit area.
