Advantage Gelcoater
Remove cap from charging valve on top of resin accumulator.
Attach charging hose (located on manifold) to the charging valve on top of
the resin accumulator. (See figures 24 & 25)
Open air valve on manifold for approximately 2 to 3 seconds (resin/
gelcoat moves slowly on a re-charge - this may not be enough time).
Shut off air valve and remove-charging hose from top of accumulator and
replace the charging valve cap (should check for leaky valve before
replacing cap).
Unlock the gun trigger.
Place an appropriate empty container under the gun-head.

NOTE
This charge of air will force any resin from the accumulator
into the hose set and open gun. The poly ball inside the
accumulator will be forced against the seat at the bottom
of the accumulator. If air comes from the gun head - check
to make sure poly-ball in accumulator is seating properly.
