Charging Accumulators:
Many applications will not require charging the accumulators; in those applications the
accumulator can be used as a surge chamber. These are low pressure spray or pour
applications where fluid pressures are medium to low.
In some cases only a line pressure charge on the resin accumulator will be necessary.
These will be applications where a medium fluid pressure is being used, most likely a
spray or a medium viscosity pour application. The line charge procedure uses the
charging hose attached to the air manifold.
For high fluid pressure applications charging the accumulators to 280psi to 300psi may
be required. These are applications using filled resins or spray putties. This will require
a charging pump or similar device a high pressure tank and regulators can also be
used.
If you do a test
as described in the “Testing & Adjusting Manual” and find it necessary to
charge the resin accumulator or both accumulators repeat the test after performing the
charging procedure to confirm an even cure.
Note: It is not required to charge a catalyst accumulator for External Mix systems.

Charging Procedures: Line Charge
1. Shut off air to the resin pump by either turning regulator to zero or turning the
pump control valve to the off position.
2. Lock the gun in the on 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 (Allen wrench) into the top
of the charging valve.
4.
Push the quick coupling on charging hose onto the charging valve on top of the
resin accumulator. Hold the in place for approximately 5 seconds.
Note: During charging of the accumulator, if air is heard exiting the front of the
gun or appropriate valve, this indicates that the polyball in the accumulator is not
seating properly. Repair the accumulator as needed.
