DO NOT open or attempt to repair the motor on your Fill-Rite pump. Return it to the place of purchase for service.
Opening the motor case will compromise the integrity of the Explosion Proof construction and void any existing
warranty, approvals, and certifications (i.e.: ATEX, UL listing, CE, etc.).
Disconnect all power prior to performing any service or maintenance. Failure to disconnect the power may cause
electrical shock, or unexpected starting of the motor, resulting in injury or death.
