24. Attach the charging system to the resin accumulator by connecting the black charging hose
to the charging valve on top of the resin accumulator.
Note
Do not overtighten the charging pump hose.
25. Open the main regulator on top of the tank.
26. Set the desired pressure on the charging regulator attached to the charging valve.
27. Slowly open the ball valve connected to the charging hose to charge the accumulator.
28. Allow approximately 5 seconds for charging before closing the valve again.
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.
Note
For spray applications, charge accumulators to between 280 to 300 psi in
general. 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.
29. Disconnect the charging hose form the resin accumulator.
30. Check the top of the accumulator for leaks by applying a light fluid (such as water) to the top
of the accumulator valve body.
31. If any air leaks are detected, remove and repair the charging valve.
32. Close the gun and flush into an appropriate container or close the appropriate valve.
33. Repeat this procedure on the catalyst accumulator.

1. Trigger the gun or use the priming button to move the pump until it is at the bottom of the
stroke (lowest position).
2. Prepare your gun as follows:
If you have an external mix gun:
Brush gelcoat spray tip and catalyst tip with solvent.
If you have an internal mix gun:
Flush the mix chamber with solvent.
3. Turn the air motor regulator counterclockwise to lower the air pressure to zero.
4. Place an appropriate container under the ball valve if a return hose is not installed.
5. Open the ball valve at the bottom of the resin filter housing to relieve resin pressure to the
supply container.
Note
It is important to release fluid pressure in the hose that is no longer going to be
in use.
6. Release the pressure in the gelcoat accumulator by pushing a small dull rod (such as an Allen
wrench) into the top of the accumulator charging valve.
