13. Attach the charging pump by connecting the black charging hose to the charging valve on
top of the resin accumulator.
Note
Do not overtighten the charging pump hose.
14. Pull the charging pump handle all the way out and connect the air hose to the male quick
disconnect on the charging pump.
CAUTION
Not pulling out the handle before attaching the air line can cause bodily
injury or damage to the charging pump.
15. Pump the charging handle with steady even strokes until the gauge on the charging pump
reads approximately 280 psi.
Note
280 to 300 psi is recommended for most applications, but some materials or
applications may require different charging pressures to achieve an even flow
of material. Increase or decrease the charge by 5 psi increments as required to
fine tune the accumulator charge.
Note
The gauge will only show an accurate reading on the down/in stroke while
pressure is building.
Note
If air is exiting the front of the gun or valve during accumulator charging, the
poly ball in the accumulator is not seating properly. Repair the accumulator as
needed.
16. Disconnect the air hose form the charging pump and remove the charging pump hose from
the resin accumulator.
17. Check the top of the accumulator for leaks by applying a light fluid (such as water) to the top
of the accumulator valve body.
18. If any air leaks are detected, remove and repair the charging valve.
19. Close the gun and flush into an appropriate container or close the appropriate valve.
20. Repeat this procedure on the catalyst accumulator.
Charging with High Pressure Tank and Regulators
21. Shut off air to the resin pump by turning the pump control valve to the off position.
22. Lock the gun in the open position over an appropriate container or open the ball valve at the
bottom of the resin filter.
Note
For catalyst charging, lock the gun in an open position over an appropriate
container or open the recirculation/dump valve on the manifold.
23. Relieve any existing charge by inserting a blunt object (such as an Allen wrench) into the top
of the charging valve.
