• 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).
• 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.
• 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)
• Connect the motor lead wire to PCB1 of the electrical box. (Be sure to match colors of the PCB connectors and motor
lead wire connectors).
• Be sure to attach the outlet grille onto the shroud after replacing the fan motor.
