(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 insulation sheet with the screw holes on the insulation sheet 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 5 screws that were
removed in step (3).
If the screws are l 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,
DB02 and DB03 is “0.55N•m (0.41ft•lbs)” and it for Q201 is “1.2N•m
(0.89ft•lbs)”.
(9) Re-connect the connectors and terminals(
1
).
Be sure that all the connectors and the terminals are connected
correctly and securely inserted. 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 screws for the terminals is “1.2N•m (0.89ft•lbs)”.
(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.
