For high fluid pressure applications, it may be required to charge the accumulators to between
280 and 300 psi. These are applications using filled resins or spray putties. To charge the
accumulators, you will need a charging pump or similar device or a high-pressure tank and
regulators. If you have a charging pump, follow the steps for a Hand Pump Charge. To charge
with a high-pressure tank and regulators, follow the steps for Charging with High Pressure Tank
and Regulators.
If you perform a pour test and find it necessary to charge one or both accumulators, repeat the
pour test after charging and confirm an even cure.
Note
It is not necessary to charge a catalyst accumulator for external mix systems.
Line Pressure Charge
1. Shut off air to the resin pump by turning the pump control valve to the off position.
2. Lock the gun in the open position over an appropriate container or open the ball valve at the
bottom of the resin filter if one is installed.
Note
For catalyst charging, lock the gun in the open position over an appropriate
container or open the recirculation/dump valve on the manifold.
3. Relieve any existing charge by inserting a blunt object (such as an Allen wrench) into the top
of the charging valve.
4. Push the quick coupling on the charging hose onto the charging valve on top of the resin
accumulator and hold in place for approximately 5 seconds.
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.
5. Remove the charging hose from the resin accumulator.
6. Check the top of the accumulator for leaks by applying a light fluid (such as water) to the top
of the accumulator valve body.
7. If any air leaks are detected, remove and repair the charging valve.
8. Close the gun and flush into an appropriate container or close the resin return valve.
9. If you need to charge the catalyst accumulator (not normally required), follow the same
procedure on the catalyst system.
Hand Pump Charge
10. Shut off air to the resin pump by turning the pump control valve to the off position.
11. Lock the gun in the open position over an appropriate container or open the ball valve at the
bottom of the resin filter if installed.
Note
For catalyst charging, lock the gun in an open position over an appropriate
container or open the recirculation/dump valve on the manifold.
12. Relieve any existing charge by inserting a blunt object (such as an Allen wrench) into the top
of the charging valve.
