4. Ensure that key 'B' is in place on the motor shaft, then push the fan (410) onto the shaft. Ensure that:
The end of the shaft aligns with the bottom of the cavity in the fan.
The back of the fan is 2.5 mm from the ducting sheet.
5. Secure the fan to the shaft with the screw (454): tighten the screw to a torque between 7 and 9 Nm.
6. Use a suitable lubricant on the coupling element (411) then fit the element to the coupling hub.
7. Align the coupling element in the hub with the coupling in the fan and fit the motor to the pump.
8. Secure the motor with the four screws (421). Tighten the screws to a torque of between 10 and 12 Nm. Note
