If the terminal box position needs to be changed, ensure 
that the electrical supply is turned off and close the 
isolation valves before removing the Allen screws.

To change control box position:

• 

Remove the four (4) Allen screws (4 or 5mm 
wrench) while supporting the stator (motor).

• 

Carefully separate the stator from the pump 
chamber and rotate it to the correct terminal box 
orientation.

• 

Replace the Allen screws and tighten diagonally 
and evenly (7 ft. –lb. torque).

• 

Check that the motor shaft turns freely.  Remove 
the large screw in the middle of the nameplate, 
insert a small flat blade screwdriver into the end of 
the shaft, and turn gently.

• 

If the shaft does not turn easily, repeat the disas-
sembly/reassembly process.

Arrows on the side or bottom of the pump chamber
indicate direction of flow through the pump.
