(6) Set the dip switch (SW800) setting of the service board to match the switch setting from the original PCB.
- Set the dip switch (SW800) depending on the position of the IPDU within the electrical box, as shown in
the following diagram.

(7) Align the heat sink with the screw holes on the heat sink and the mounting holes on the PCB with the PCB
mounts. And fix the Compressor IPDU to the outdoor control unit by the spacers (
3
).
(8) Screw the Compressor IPDU to the heat sink by the four
screws that were removed in step (3). If the screws are loose,
the effect component will generate heat, and cause it to
breakdown. Do not use an electric driver or an air driver.
As it can cause component damage. The torque of the
screws for DB01 is “0.55N•m” and it for Q201 is “1.2N•m”.
(9) Re-connect the connectors and fast-on terminals (
1
). Be
sure that all the connectors and the fast-on terminals are
connected correctly and securely inserted.
(10) If the components on the PCB were bent during this
procedure, straighten them so they do not touch other
parts.
(11) Install the cover, then turn on the supply. Check the
operation.
