(7) Install the service P.C. boards (A) and (B) in the outdoor unit controller.
(Make sure that they are firmly secured to the card edge spacers (

).)
(8) Securely connect the service P.C. boards to the chassis using the earthing screws (
5
), (
6
) removed in step 4.
If either of the screws is loose, it will pose a risk of device failure by degrading noise control, so take care
while engaging in the work.
Nevertheless, do not use an electric or pneumatic screwdriver under any circumstances as it may lead to
component damage.
(9) Connect the wiring using the connectors and fast-on terminals removed in step (3).
Make sure that the connectors and fast-on terminals are connected correctly and securely.
(10) If any component on the P.C. board becomes crooked during replacement, straighten it without touching
any other component.
(11) Mount the terminal block sub-assembly (
1
) and firmly secure it using the screws (
3
).
(12) Securely connect the red, white and black leads from the service P.C. board (A) to the power supply
terminal block (

) using the screws (
2
).
(13) Put the cover on, turn on the power, and check operation.
