CAUTION
• 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.)
Secure using upper 2 screws for floor installations. If possible, also attach two lower screws.
At first secure the installation board using 5

Look for the inside wall structures (Intersediats support or pillar and finally install the unit after level surface has been checked.)
When practicing the half-console, make su

ely.
Otherwise, it could fall.
Adjustment of the installation boa

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 conventional 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.
Keep the openings of the pipes cover

Clamp Wiring holder
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.

Mounting of connecting wires
In case of faulty wiring connection, the indoor unit stops, and then the run lamp tur
ns 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 passeson the sensor, it may not detect suction temperature and/or humidity.
• Earth wi
re

eason.
• 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 wires. CENELEC code for cables Required field cables.
Pass the r

INSTALLATION TEST CHECK POINTS
After installation
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 terminal 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. (Three-minutes restart preventive timer) When the air-conditioner is restarted or when changing the operation, 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 installation, 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 and 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 wr
ench key
.
Gas side : Fully open the service valve Carry out cooling operation. (If indoor temperatur

re
gauge become 0.01MPa, stop cooling
operation and close the service valve (gas side).

CONCERNING TERMINAL CONNECTION FOR AN INTERFACE
Remove the front panel and lid of control. There is a terminal (respectively marked with CNS) for the indoor control board. In connecting an interface, connect to the respective terminal securely with the connection harness supplied with an option
“Interface connection kit
SC-BIKN2-
E”
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
connection kit SC-BIKN-
E”
.

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.

Turn off the power source, and turn it on after 1 minute. Point the wireless remote control that was set according to the procedure described on the left side at the indoor unit and send a signal by pressing the ACL switch on the wireless remote cont
rol.
Since the signal is sent in about 6 seconds after the ACL switch is pressed, point the wireless remote control at the indoor unit for some time.

Check that the reception buzzer sound “pip” is emitted from the indoor unit. At completion of the setting, the indoor unit emits a buzzer sound “pip”. (If no reception tone is emitted, start the setting from the beginning again.)
Fitting
Do remove the air filter. Cover the body with the front panel. Fit the 6 latches in the lower section, then 3 latches in the upper section. Tighten the 5 set screws. Fit the air filter. Fit the air inlet panel.
