the PCB mounts. And fix the Compressor IPDU to the outdoor control unit by the spacers (

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 "0.55Nm" and it for Q201 is "1.2Nm".
(9) Re-connect the connectors and fast-on terminals (
sure that all the connectors and the fast-on terminals are
