Installation Notes

  1. Disconnect power and verify zero energy; remove guard and fan shroud.
  2. Unplug motor leads; mark connectors for polarity/orientation.
  3. Release mounting hardware; separate motor from gearbox/pump adapter.
  4. Seat replacement motor; align coupling; torque per manual.
  5. Reconnect wiring; test at low pressure before returning to service.

Real tip: Inspect fan and louvers for debris—restricted cooling shortens motor life.

When to Rebuild / Replace

  • Motor hums but shaft doesn’t rotate under load.
  • Breaker or GFCI tripping during start-up.
  • Burnt odor or visible arcing from motor housing.
  • Inconsistent pressure despite verified pump packings.
