CONCERNING TERMINAL CONNECTION FOR AN INTERFACE
Remove the air inlet panel, lid and front panel.
Remove the control cover. (Remove the screw.)
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 optional “Interface connection kit SC-BIKN-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”.

• 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 insulation pad placed over
the heat insulating material’s slit area.
Cover the coupling with insulator and then cover it with tapes.
Vinyl tape
Use an attached insulation pad for heat insulation.
Position it so that the slit area faces upward.

If FDC71VNP is connected, use reducer at gas side
of indoor unit to change the pipe size from ø15.88 to
ø12.7. (Reducer is attached in the outdoor unit

INSTALLATION TEST CHECK POINTS
After installation
The power supply voltage is correct as the rating.
No gas leaks from the joints of the operation 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.
Operation 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 again 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.
Open the air inlet panel.
Remove the lid.
Remove the wiring 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.
Attach the lid.
Close the air inlet panel.

Installing the air-cleaning filters
1. Open the air inlet panel and remove the air filters.
2. Install the air-cleaning filter in the filter holders, and then install the filter holders in the air conditioner.
• Each air-cleaning filter can be installed in the left or right filter holder.
3. Install the air filters and close the inlet panel.
Go through all installation steps and check if the drainage is all right.
Otherwise water leak may occur.
Turn off the power supply, 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 control.
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.)
Connect charge hose to check joint of outdoor unit.
Liquid side : Close the liquid valve with hexagon wrench key.
Gas side : Fully open the gas valve.
Carry out cooling operation. (If indoor temperature is low, operate
forced cooling operation.)
After low pressure gauge become 0.01MPa, stop cooling operation
and close the gas valve.

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.
