NOTICE: UNIT ROTATION IS CLOCKWISE WHEN
VIEWED FROM MOTOR END. INCORRECT
ROTATION MAY CAUSE DAMAGE TO THE
PUMP AND VOIDS WARRANTY.
• Three Phase Motors ONLY:
To check the pump rotation, observe pump while switch-
ing the electrical power ON then OFF quickly. If incorrect,
have a qualifi ed electrician interchange two of the three
motor power wires.

Motor to Pump – Shaft Alignment
• After completion of the frame mounted unit baseplate
installation, the motor and pump shaft alignment MUST
be checked, see Figure 6, and the coupling spacer must
be reinstalled.

• If realignment is required, ALWAYS make the required
adjustments to the motor, shimming as necessary.

• To check for PARALLEL misalignment, place a dial
indicator on one coupling hub, rotate the hub 360° while
observing the indicator readings from the outside diameter
of the other hub. Parallel alignment requires a Total
Indicator Reading (TIR) of 0.005" (0.13 mm), or less.

IMPELLER TO SPRING FROM THE SHAFT
WHEN
UNSCREWED.
• To remove the impeller it is necessary to heat the center
hub area with a hand propane torch for approximately 30
seconds. Unscrew the impeller (101) from the shaft, turn the
impeller COUNTERCLOCKWISE while holding the shaft.
Motors have a screwdriver slot or hex provided under the
motor end cap. Examine the impeller for wear or damage and
replace as necessary. Discard the shaft sleeve O-ring (412A).
