This Interface board is commonly installed in different models before shipment. When the board assembly is to
be replaced, check the displayed inspection contents below and replace the board in accordance with the
model, following the below procedure.
Replacement steps:
(1) Turn off the power supply of the outdoor unit.
(2) Remove all of the connectors and fast-on terminals connected to the interface board. (Remove the
connectors and fast-on terminals by pulling the connector body. Do not pull the wire).
(3) Remove the interface board from the six PCB mounts (1).
(4) Cut the jumper wires of the service board, as instructed in the table below.
The jumper setting differs from original supplied PCB, therefore be sure to configure the Jumpers as in the
table below.
If the model is not specified, inspection code “L10” is displayed and the equipment will not operate.
(5) Set the dip switch settings of the service board to match the switch settings of the PCB being replaced.
(6) Install the service board to the outdoor control unit (Confirm that it is securely fixed to the PCB Mounts).
(7) Connect the connectors and fast-on terminals (Confirm that they are correctly and securely inserted).
(8) If a component on the board is bent during board replacement, adjust it manually ensuring that it is not
short or contact other parts.
(9) Install the cover, then turn on the power supply. Check the operation.
