(5) 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.
Ex. MMY-MAP1006FT8P
(6) Apply the Silicone Thermal Grease to the semiconductors (DB01, Q201) on the service PC board, and align the
positions of the heat sink holes to mount the Compressor IPDU on the outdoor control unit. And fix the Compressor
IPDU to the outdoor control unit by the spacers
(7) 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 and Q201 is "1.2Nm".
(8) Re-connect the connectors and Faston and screw terminals(①).
Be sure that all the connectors and the screw terminals
are connected correctly and securely inserted.
Note: ①When connecting the white lead wire which is connected to CN02,
be absolutely sure that it is passed through the T611 transformer
and then connected
②When connecting the black lead wire which is connected to CN03,
be absolutely sure that it is passed through the T612 transformer
and then connected
(If it is not passed through the transformer, it will not be possible for
the input current level to be measured correctly, and a compressor
failure may result.)
(9) If the components on the PCB were bent during this procedure,
straighten them so they do not touch other parts.
(10) Install the cover, then turn on the supply. Check the operation.

(③).
Uniformly apply the Silicone Thermal Grease to the heat dissipating surfaces of the IPM (Q201)
and rectifier (DB01).
Note: Do this work carefully since allowing any dirt, scratches, etc. to be left on the PC board
mounting areas of the semiconductors will impair the heat dissipation effect and may result
in a failure.
Silicone Thermal Grease use one of the following
･Momentive Performance Materials ''TIG1000''
･Dow Corning Toray ''SC102''
･Mizutani Electric Ind ''HSC1000''
･Shin-Etsu Chemical ''G-746'' or ''G-747''
