1 To mount the motor be sure to place the lead wire outlet downward.
(Adjust the propeller fan and shroud not to contact with each other).
2 Fix the motor lead wire onto the motor clamp using a plastic tie as shown in the table on the previous page to
avoid obstructing the propeller fan.
3 Mounting propeller fan:
Insert the skidding protection part of the fan boss matching with the motor shaft notch; tighten the nut after
the shaft screw fully comes out. (Tightening Torque 20 Nm)
4 Connect the motor lead wire to the electrical box DIP-IPM.
(Be sure to match colors of the PCB connectors and motor lead wire connectors).
5 Be sure to attach the outlet grill onto the shroud after replacing the fan motor.
