5. Tighten coupling screws to 62 ft-lbs (75 and 100 HP motors to

6. Check to see that the gaps between the coupling halves are
equal. Loosen and readjust, if necessary.
7. Make sure the pump shaft can be rotated by hand. If the shaft
cannot be rotated or it jams, disassemble and check for
misalignment.
8. Prime the pump.
9. Follow the wiring diagram on the motor label for the correct
motor wiring combination which matches your supply voltage.
Once this has been confirmed, reconnect the power supply
leads to the motor.
10. Check the direction of rotation by bump-starting the motor.
Direction of rotation must be left to right (counter-clockwise)
when looking directly at the coupling.
11. Switch off the power, then mount the coupling guards. When
the coupling guards have been mounted, the power can be
switched on again.
16. Parts list
Grundfos offers an extensive parts list for each CR pump model.
A parts list typically covers the following items:
• a diagram of pump parts which we recommend to have on
hand for future maintenance
• a list of prepacked service kits covering the pump components
most likely to be exposed to wear over time
• complete chamber stacks needed to replace the rotating
assembly of each model.
These parts lists are available separately from the Grundfos
literature warehouse or as a set with extensive service
instructions in the Grundfos CR Service Manuals.
