(5) Remove the noise filter P.C. board assembly by unlocking the four PCB mounts used to secure the P.C. board ⑦.
(6) Remove the line filter ⑨ and its leads, both connected to the screw-on terminals ⑧ of the just-removed noise
filter P.C. board (A), and reinstall them on the service P.C. board (A) by firmly connecting them to the screw-on
terminals ⑧ in the same manner as before.
(7) Install the service P.C. boards (A) and (B) in the outdoor unit controller.
(Make sure that they are firmly secured to the PCB mounts ⑦ and ⑩.)
Line Filter installation:
Screw the line filter and the connecting wires
together to the terminals as right figure.
The torque of 6 screws of the line filter is
"1.84ft･lbs (2.5Nm)".
Please check that the screws connecting
the line filter are not loose. If the screw is loose,
the screw will generate heats, and cause the
line filter to breakdown.
Do not use an electric driver or an air driver,
as this can cause damage to the line filter.
Connect the wires according to the wiring
diagram.
(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 Fastons removed in step (3).
Make sure that the connectors and Fastons 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 filter cover ① and firmly secure it using the screws ②.
(12) Put the cover on, turn on the power, and check operation.
