ELECTRICAL WIRING WORK
Preparation of indoor unit
In case of faulty wiring connection, the indoor unit stops, and then
the run lamp turns on and the timer lamp blinks.
Mounting of connecting wires
1 Open the air inlet panel. Use cables for interconnection wiring to avoid loosening of the wires.
2 Remove the lid.
CENELEC code for cables Required field cables.
3 Remove the wiring clamp.

4 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

HOW TO RELOCATE OR DISPOSE OF THE UNIT
○ In order to protect the environment, be sure to pump down (recovery of refrigerant).
○ Pump down is the method of recovering refrigerant from the indoor unit to the
outdoor unit when the pipes are removed from the unit.
<How to pump down>
1 Connect charge hose to check joint of outdoor unit.
2 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.
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.

INSTALLING TWO AIR CONDITIONERS IN THE SAME ROOM
When two air conditioners are installed in the same room, use this setting when the two air conditioners are not operated with one wireless remote control. Set the
wireless remote control and indoor unit.
Setting the wireless remote control
1 Pull out the cover and take out batteries.
2 Disconnect the
switching line next
to the battery with
wire cutters.
Disconnect
3 Insert batteries. Close the cover.
CONCERNING TERMINAL CONNECTION FOR AN INTERFACE
1 Remove the air inlet panel, lid and front panel.
2 Remove the control cover. (Remove the screw.)
3 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".
Test run
Air conditioning operation is normal. The wireless remote control is normal.
No abnormal noise. Operation of the unit has been explained to the customer. (Three-minutes restart preventive timer)
Water drains smoothly. When the air conditioner is restarted or when changing the operation, the unit will not start operating for
Protective functions are not working. approximately 3 minutes. This is to protect the unit and it is not a malfunction.

Setting an indoor unit
1 Turn off the power supply, and turn it on after
1 minute.
2 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.
3 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.)
