MPC, and as such may actuate without warning. Care should be taken to
keep loose clothing and other objects away from the pump motor.
The MPC was designed to be service free. It contains no user-
maintainable components. Disassemble the MPC enclosure only for
initial field wiring, or as instructed to do so within this manual. Evidence
of unauthorized disassembly shall void the warranty.

users and systems should the pump activate.
