CHAPTER 7-System Start Up/Troubleshooting

Set pressure at 0 psi and turn on pneumatic pressure from system.

Turn on the recirculation circuit and/or open the filter bypass valves.

Using the priming button, slowly ramp up pressure to cycle Fluid Sections until solid flow is
achieved. While this is being done, observe both the up and downstrokes have a steady fluid
stream.

Close recirculation valves and/or gun.

Using the priming/manual override circuit, pump the system up to operating pressure. Note which
way the pump is traveling and measure from the top of the Packing Nut to the end of the Piston
Rod.

After 15 min, bypass some fluid to get the Fluid Section Traveling in the opposite direction.
Measure from the top of the Packing Nut to the end of the Piston Rod.

Let the system set for approx 15 min.

If after 15 min. the Piston Rod assembly has moved then there is a problem with the one or more
of the ball seats.

o

If the Fluid Section is on the upstroke, and continues to move up after the recirculation

and/or gun has been closed, then the Piston Body ball seat, O-ring or Piston Seal/Cup
assembly, is faulty.

o

If the Fluid Section is on the downstroke, and continues to move down after the

recirculation and/or gun has been closed, then the Foot Valve ball seat and/or o-ring is
faulty.

Please refer to the Fluid Section Troubleshooting guide for more precise information.
