6. Check the entire pumping system to verify that the
proper inlet and discharge valves are fully open, and that
the drain valves and other auxiliary valves are closed.
7. Install vacuum and pressure gauges on the pump in the
1/4” NPT connections provided to check suction and
discharge conditions after pump start-up.
8. Check the wiring of the motor, and briefly turn on the
power to make sure that the pump rotates in the
direction of the rotation arrow.
START UP PROCEDURES
NOTICE:
Consult the "Troubleshooting" section of this manual if
difficulties during start up are experienced.
1. Start the motor. Priming should occur within one minute.
2. Check the suction and discharge pressure to see if the
pump is operating within the expected conditions.
Record pressures in the ‘Initial Start Up Information’
section.
3. Check for leakage from the piping and equipment.
4. Check for overheating, excessive noise or vibration of
the pump, reducer, and motor.
5. Check the flow rate to ensure the pump is operating
within the expected parameters. Record flow rate in the
‘Initial Start Up Information’ section.
6. Check the pressure setting of the relief valve by briefly
closing a valve in the discharge line and reading the
pressure gauge. This pressure should be 20 psi (1.4 bar)
higher than the maximum operating pressure.
Do not run the pump for more than 10-15 seconds
with the discharge valve completely closed.
If adjustments need to be made, refer to "Relief Valve
Setting & Adjustment."
Incorrect settings of the pressure relief
valve can cause pump component
failure, personal injury, and property
damage.
Hazardous pressure
can cause personal
injury or property
damage
