In case of P-GP160NAPU
1 The air panel has the wiring connectors (1) to (5) shown in
the right figure. Remove the tape that secures the wiring
connector and pull out the wiring connector.
2 Connect each wiring to the connector on the PCB inside the
electrical box of the indoor unit at the position shown below.
Make sure to pass the wirings through the cable band as
shown in the figure below.
3 After connecting the connector, tighten the cable band to
secure it.

In case of attaching this air panel on the RCI-FSR series indoor unit,
remove the relay wiring attached to indoor unit PCB. After that, connect
the wiring attached to the air panel directly to the PCB as described above.

Restart the operation. If a power failure occurs while the elevating grille is descending, it will be stored once in
the decorative panel for protection even if the descending operation is performed after the power is restored.
After that, normal operation is possible.
If slack occurs in the suspension wire, it will be stopped forcibly. Correct the slack in the suspension wire.
Refer to "Countermeasure for Slack of Suspension Wire" in Section 3.
This might occur when there is something on the air inlet grille or when the air filter is not installed properly.
Remove the placed object and install the air filter properly.
This is an automatic operation when the air inlet grille is not stored correctly. It is not abnormal.
A little tilt is not abnormal. This is because there is a gap in the winding of the four suspension wires. If it is
extremely inclined (more than 30°), the elevating mechanism may be defective. Contact your contractor or
distributor.
This might occur when the air inlet grille is not properly stored. Operate the elevating grille again and store the
air inlet grille in the correct position.
This is the drive sound of the elevating mechanism. It is not abnormal.

• Make sure to set the DIP switch. If it is operated without setting, the
opening and closing angle of the louver will be different. It may cause
dew condensation.
• All indoor and outdoor units must be shut down prior to attempting to
make DIP Switch adjustments, otherwise, the settings will not take
effect.
