Operation
Pressure Control Valve Adjustment
Pressure Control Valves (PCV) must be set to the desired single hose operation pressure.
A retaining ring must be in place at all times during pressure control valve adjustment.
1 Inspect complete piping system and supports to ensure that no piping loads are being placed
on the pump.
2 Ensure all valves and fittings in piping system are in the start-up or operating positions.
3 Jog the pump motor to verify proper pump rotation.
Start Up Procedures
Note: Consult the "Troubleshooting" of this manual if difficulties during start-up occur.
1 Start the motor. Priming should occur within one minute.
2 Check the vacuum and pressure gauges to ensure the system is operating within expected
parameters. Record the gauge readings in the "
Initial Start Up Information " section of this
manual for future reference.
3 Inspect piping, fittings, and associated system equipment for leaks noise, vibration and
overheating.
4 If possible, check the flow rate to ensure the pump is operating within the expected
parameters. Record flow rate in the "
Initial Start Up Information " section of this manual.
5 Check the pressure setting of the relief valve by momentarily closing a valve in the discharge
line and reading the pressure gauge, this pressure should be 10 - 20 psi (69 - 138 kPa) higher
than the maximum system operating pressure, or the external bypass valve setting
Operation without guards in place can cause serious personal injury, major property
damage or death.
Operating pump against a closed valve can cause system component failure, personal
injury and property damage.
WARNING !
Incorrect settings of the pressure relief valve can cause system component failure,
personal injury and property damage.
