CAUTION
• During the installation, do not lean on the control box or th
e 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.)
Secure using upper 2 screws for floor installations.
If possible, also attach two lower screws.

Remove the fixing screw of clamp.
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.
Fix the connecting wire by wiring clamp.
Pass the connecting wire through the wiring holder.

• 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.
Use cables for interconnection wiring to avoid loosening of the

INSTALLATION TEST CHECK POINTS
After installation
The power source voltage is correct as the rating.
No gas leaks from the joints of the service valve.
Power cables and crossover wires are securely fixed to the term
inal board.
The screw of the lid is tightened securely.
Test run
Air-conditioning operation is normal.
No abnormal noise.
Water drains smoothly.
Protective functions are not working.
The wireless remote control is normal.
Operation of the unit has been explained to the customer. (Thre
e-minutes restart preventive timer)
When the air-conditioner is restarted or when changing the oper
ation, the unit will not start operating
for approximately 3 minutes. This is to protect the unit and it
is not a malfunction.
Service valve is fully open.
The pipe joints for indoor and outdoor pipes have been insulated.
Check the following points again after completion of the instal
lation, and before turning on the power. Conduct a test run aga
in and ensure that the unit operates properly.
At the same time, explain to the customer how to use the unit a
nd how to take care of the unit following the user’s manual.
Connect charge hose to service port of outdoor unit.
Liquid side : Close the service valve with hexagon w
rench key.
Gas side : Fully open the service valve
Carry out cooling operation. (If indoor temperatu
re is lo

CONCERNING TERMINAL
CONNECTION FOR AN INTERFACE
Remove the front panel and lid of control.
There is a terminal (respectively marked with CNS) for the indo
or control
board.
In connecting an interface, connect to the respective terminal
securely with
the connection harness supplied with an optional
“Interface connection kit
SC-BIKN-

” and fasten the connection harness onto the indoor control box
with the clamp supplied with the kit.
For more details, please refer to the user’s manual of your
“Interface

Install the indoor unit according to the following instructions.
Secure the upper, right, and left spaces according to the
right figure.
Do not let the horizontal bar obstruct wind from blowing out
upward/downward or reception from the wirelee remote control
.
The lattice size should be 70 % or greater of the open rate.
Cut the jumper cable (JP173) on the indoor circuit board to
control the blow-out angle.
