HOW TO RELOCATE OR DISPOSE OF THE UNIT
CONCERNING TERMINAL CONNECTION FOR AN INTERFACE
CAUTION
In case of faulty wiring connection, the indoor unit stops, and
then the run lamp turns on and the timer lamp blinks.
Use cables for interconnection wiring to avoid loosening of the
wires.

In order to protect the environment, be sure to pump down (recovery of refrigerant).
c
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 service port 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.)
③
After low pressure gauge become 0.01MPa, stop cooling operation
and close the gas valve.
Forced cooling operation
Turn on a power supply again after a while after turn off a power supply.
Then press continually the ON/OFF button 5 seconds or more.
1. Open the air inlet panel and remove the air filters.
2. Install the filter holders, with the air-cleaning filters installed in the 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.
After installation
The power supply voltage is correct as the rating.
No gas leaks from the joints of the operational valve.
Power cables and crossover wires are securely fixed to the terminal board.
The screw of the service panel is tightened securely.
Operational valve is fully open.
The pipe joints for indoor and outdoor pipes have been insulated.
Preparation of indoor unit
Installing the air-cleaning filters
①
Open the air inlet panel.
②
Remove the service panel.
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
and outdoor connections.
3 ) Fix the connection wire using the wiring clamp.
⑤
Fix the connecting wire by wiring clamp.
⑥
Attach the service panel.
⑦
Close the air inlet panel.

Test run
Air conditioning operation is normal.
No abnormal noise.
Water drains smoothly.
Protective functions are not working.
The 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.
Check the following points again after completion of the installation, and before turning on the power. Conduct a test run agai
n 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.
Unit ON/OFF button
①
Remove the front panel and lid of control.
②
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”.
