(6) Align the motor key and keyway with the coupling keyway and slowly lower the motor into position
ensuring that the key slides into the coupling keyway.
(7) Prior to lowering the motor completely, rotate the motor so that the mounting holes are aligned
with the holes in the motor support.
(8) Insert the four motor bolts into the proper holes and tighten evenly using an alternating crossing
pattern to ensure proper alignment.

(1) Following general safety and electrical instructions, disconnect the power to the motor and
remove power cords.
(2) Loosen and remove the four motor bolts.
(3) Attach a strong sling or chains to the motor lifting lugs or eyebolts to ensure that the motor is
balanced when lifted vertically.
(4) remove the coupling guards
(5) Loosen, but do not remove the coupling bolts
(6) Slowly lift the motor off the pump assembly being careful to retain the shaft key. If the motor
does not slide easily out of the coupling do not raise the pump into the air, dropping the pump
end can cause damage. Fix the pump base to the floor or bench and lift motor again.
For any removal or installation procedures, always disconnect the power first.
Failure to observe this precaution can result in serious accidents.
WarNING !!
Extreme caution should be exercised in this operation since the pump may be under system pressure
at this point. Before proceeding with the removal of the motor be sure to relieve the system pressure
in the pump.
Use a pressure bleed valve in hot water applications where water temperature could cause physical
injury.
