9. Empty the fill tube of fluid, and place it on the fitting near the switch, extending upwards, open to the
atmosphere.
10. Ensure that the eccentric box of the pump has been filled to the appropriate level with the correct
(normally Pulsalube 7H ™
11. Adjust the pump to the zero stroke (0%) position.
) hydraulic fluid.
12. If the pump is not already hydraulically primed, remove the PTP valve from the top of the pump
head. Using a plastic funnel or similar, slowly pour hydraulic fluid into the pump head cavity until
full.
13. Inspect the PTP valve to ensure the sealing o-ring is still in position, and re-install the valve.
14. Adjust the pump to full (100%) stroke.
15. In order to fully balance and evacuate the leak detection system, the pump must now run at normal
discharge pressure for a period of one hour. This ensures that excess barrier fluid is fully evacuated
from the system.
16. Supply either process fluid, or test fluid (i.e. water) to the suction fitting and ensure that the discharge
system is configured for safe operation. The pump can be started with minimal discharge pressure
and then slowly brought up to full pressure, if the system allows for this.
17. Apply power and start the pump. Hold down the PTP valve momentarily and observe the middle port
under the diagnostic cover. If no fluid is coming from this port, stop the pump and return to step 11.
If fluid is present, continue to step 18.
18. Slowly increase the discharge pressure to full operating pressure, and continue to run the pump for a
period of one hour.
19. During this time, excess barrier fluid will be displaced from the system into the short length of tubing
attached to the exit port, balancing the system for proper operation. A small pen mark on the tube can
assist in observing this process visually.
20. After the one-hour startup period, remove the tubing and connection from the housing body and
reinstall the pressure gage. Remove the fitting from the fill port and replace with the supplied pipe
plug.
21. Reconnect the alarm switch to the external system if necessary.
22. The pump and pressure leak-detection system are now properly prepared and ready for normal
service. During normal operation, the gauge should indicate 0 (zero) pressure.
Under certain circumstances, the system may not completely evacuate excess barrier fluid during
the procedure as outlined above. In these cases, after several days run time, a small amount of
pressure may build in the system. If this occurs, simply loosen the pressure gauge from the switch
housing and relieve a small amount of barrier fluid, returning the system to a zero-pressure state.
Once this startup procedure is completed, the pressure leak detection system should require no
further maintenance.
