Fan motor

Procedure

1) Perform works of items 1) to 5), 7) of

2) Remove the flange nut fixing the fan motor

and the propeller fan.
• Loosen the flange nut by turning clock-

wise. (To tighten the flange nut, turn it
counterclockwise.)

3) Remove the propeller fan.
4) Remove the lead wire from the hook fixing

the fan motor lead wires on the motor
base. (Three positions)

5) Disconnect the connector for fan motor

from the inverter.

6) Take off the fixing screws (4 pcs.) while

holding by hands so that the fan motor
does not fall.

NOTE :
Tighten the flange nut with torque 9.8Nm
(100kgf/cm).

Remarks
