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 qualified electrician interchange two of the three motor power wires.
WARNING
Extreme heat can cause personal injury or property damage.
DO NOT OPERATE PUMP AT OR NEAR ZERO FLOW. TO DO SO CAN CAUSE EXTREME HEAT, DAMAGE TO THE PUMP, PERSONAL INJURY OR PROPERTY DAMAGE.
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.
•Before checking shaft alignment, insure that the foun- dation, pump and motor holddown bolts are properly tightened.
•If realignment is required, ALWAYS make the required adjustments to the motor, shimming as necessary.
Parallel
Angular
Figure 6
•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.
•To check for ANGULAR misalignment, place a dial indica- tor on one coupling hub, rotate the hub 360° while observ- ing the indicator readings from the face of the other hub.
Angular alignment requires 0.005" (0.13 mm) TIR, or less.
•Correct alignment is achieved when parallel and angular TIR requirements are satisfied and motor holddown bolts are tight.
NOTICE: RECHECK SHAFT ALIGNMENT AFTER
MAKING ANY ADJUSTMENTS.
Operation
WARNING DO NOT OPERATE UNIT WITHOUT SAFETY GUARD IN PLACE. TO DO
SO CAN CAUSE SEVERE PERSONAL INJURY OR DEATH.
Hazardous machinery can cause personal injury or death.
NOTICE: PUMP MUST BE COMPLETELY PRIMED BEFORE OPERATION.
•After stabilizing the system at normal operating conditions, check the piping and coupling for correct alignments. If necessary, adjust pipe supports and realign the shafts following the procedures provided.
Maintenance
•Close coupled pump motors and frame mounted pump frames have permanently lubricated bearings. Additional lubrication is not necessary or possible.
•Follow the coupling and motor manufacturer’s recommendations regarding maintenance.

•For close coupled or frame mounted units:
•Remove the motor or bearing frame holddown bolts
•Remove the coupling guard and coupling spacer
•Remove the 4 casing screws (370), then utilizing the slots provided about the casing (100), pry the back
NOTICE: IMPELLER COMPRESSES THE MECHANICAL SEAL SPRING – BE PREPARED FOR THE 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
NOTICE: EXERCISE CARE HANDLING HOT IMPELLER.
• To remove the mechanical seal, remove the 4 seal housing screws (370H) and slide the seal housing assembly off the shaft. Discard the rotary half of the seal and the seal hous- ing
housing and discard it.
