Inlet Water Requirements
The supply water must meet the minimum water quality standards outlined in Section 7,
Specifications. Poor water quality will drastically shorten component life and void the warranty.
Supply water piping must be sized for 150% of the pump capacity and should match the intended
maximum duty cycle.
The inlet water must be maintained at a temperature between 55 and 70º F (12.7 and 21º C) for
proper pump performance. Premature component failure is common if water temperatures are
outside this range. Inlet water chillers should be used if the inlet water temperature is above this
range.
Only PVC, copper or rubber hoses should be used between the inlet water source and the
machine.
Drain
Cutting water is discharged from the pressure control valve through the drain port. The discharge
is considered wastewater and must be piped to an appropriate location, i.e. a sewer line.
High pressure plumbing is not required; however, piping must comply with local, regional and
national codes. The discharged water is extremely hot, with temperatures in excess of 150º F (66º
C).
