Procedure

1. Control P.C. board

1) Carry out work of 1 of

WARNING

Never disassemble the inverter for

1 minute after power supply has been

turned off because an electric shock may

be caused.

2) Remove the connectors connected to

the control P.C. board. (Indoor power

supply, Temperature sensor, PMV coil,

4-way valve coil, Compressor case

thermo, Fan motor)
• Unlock the lock of the housing part

and then remove the connectors.

3) Remove the lead wires connected to

the control P.C. board.
Compressor lead U: CN200 Red

V: CN201 White

W: CN202 Black

Reactor cord

CN05 White

CN06 White

4) Remove the earth wire from the control

P.C. board.

NOTE :

• Be sure not to confuse for Compressor

lead V (CN201 White), Reactor lead

CN05 and CN06.

• Be sure not to come-off of the

insulating sheet.

(Trust B tight screw Ø4 × 6, 1 pc.)

5) Remove the fixing screws of the control

P.C. board. (Screw with collar for fixing

element Ø3 × 16, 9 pcs. Pan S tight

screw for fixing board Ø3 × 20, 1 pc.)

6) Remove the control P.C. board.

(Supporter: 5 positions)

NOTE :

Be careful to take out because there is

sealing material for the heat sink.

7) Mount a new control P.C. board.

NOTE:

Do not forget to attach the aluminum plate

(Q201) and the insulating sheet (Q300).

(Applying a little of radiator grease at the

rear surface of the insulating sheet in

advance to adhere to the heat sink

makes easy the work.)
