Starting Up and Troubleshooting
1. Make sure system pressure is set to zero (0) psi and turn on pneumatic pressure from system.
2. Turn on the recirculation circuit and/or open the filter bypass valves.
3. Using the priming button, slowly ramp up pressure to cycle the fluid section until a solid
flow is achieved, observing the up and down strokes to make sure both have a steady fluid
stream.
4. Close the recirculation valves and/or gun.
5. Using the priming/manual override circuit, pump the system up to operating pressure.
6. Note which way the pump is travelling and measure from the top of the packing nut to the
end of the piston rod.
7. After 15 minutes, bypass some fluid to get the fluid section travelling in the opposite
direction.
8. Measure from the top of the packing nut to the end of the piston rod.
9. Let the system set for approximately 15 minutes, then remeasure.
10. If after 15 minutes the piston rod assembly has moved, there is a problem with one or more
of the ball seats; address as follows:
i)
If the fluid section is on the upstroke and continues to move up after recirculation and/or
gun has been closed, replace any of the following components that may be faulty: piston
body ball seat, O-ring, or piston seal/cup assembly.
ii) If the fluid section is on the downstroke and continues to move down after the
recirculation and/or gun has been closed, replace the faulty foot valve ball seat and/or
O-ring.
11. Check the cylinder seals for leakage.
12. Check the packing nut cavity for leakage.
13. Check the outlet fitting for leakage.
14. Check the inlet fittings for leakage.
15. Tighten or replace components as needed.
