6. Apply a system compliant anti-seize com-
pound to the motor shaft keyway and install
the motor shaft key and coupling.
NOTES: If the motor shaft key does not t
properly in the coupling keyway, lightly le the
motor shaft key until a proper t is obtained.

5. Loosen and remove the sheet metal cou-
pling guards. This allows better access to
view and preform coupling alignment in
later steps.
3. Prior to pump installation energize the motor
to determine the direction of motor rotation.
The correct rotation is indicated by arrow on
the MSD branding plate. If the rotation is incor-
rect, reverse the polarity of motor wiring to
change the direction of rotation.
NOTES: Since the branding plate is remov-
able it is important to rst verify or replace the
plate in the correct orientation. “MOTOR END”
should always face the motor end of the MSD
pump before reading directional arrow.
NOTES: Reversing polarity of the VFD power
input wires will not change the motor rotational
direction.
4. If the motor rotational direction is correct,
disconnect power to the motor according to
lock-out/tag-out procedures and complete
all electrical connections according to local
codes and regulations.
