RESIN ACCUMULATOR CHARGING
NOTE: Resin accumulator must be completely void of fluid before attempting to charge system.
1. Purge catalyst fumes from charging pump by stroking pump several times before connecting
charging pump to valve body at top of resin accumulator.
CAUTION : Raise charging pump “T” handle to full up position before connecting air supply to
charging pump. Failure to do so may result in damage to the pump and/or injury to the
operator.
NOTE: Resin pour tubes and manifold block must be removed from gun head pour nozzle
before attempting to charge resin side of system.
2. Connect air supply to charging pump. Air supply should be approximately 100 P.S.I.
3. With regulator and ball valve to resin pump power head in the off positions, open needles of
gun.
NOTE: A suitable container will be required under gun.
4. Allow fluid to drain from resin accumulator before charging.
NOTE: It may be necessary to assist the draining operation with the charging pump. Operate
the charging pump until fluid no longer flows from the gun head. If this assist method is used it
will be necessary to remove charging pump from accumulator after fluid has stopped flowing
and relieve the pressure from the accumulator by forcing air valve open with a small, flat end
rod in the same manner as you would let air out of tire inner tube.
This is necessary because 95% of the time an overcharged condition will have occurred while
purging accumulator.
5. Proceed to charge resin accumulator to 4 times the amount that the power head of resin pump
will be operated at.
In most cases 50-60 PSI power head operation will supply an adequate amount of resin to nip of
rolls.
NOTE: Charging pump gauge will read line pressure with the “T” handle up and accumulator
pressure with handle down.
NOTE: The resin accumulator must be completely void of fluid to insure an adequate charge.
An improper charge will result in surging, uneven flow of resin, and poor catalyzation.
6. Remove air supply from charging pump and charging pump from accumulator.
7. After removing charging pump, check charging valve of accumulator for a pressure seal by
placing soapy water or other appropriate fluid over valve opening. If no air bubbles appear
install seal cap.
NOTE: If air leaks from charging valve, accumulator will not hold a charge and the source of the
leak must be found and eliminated before proceeding.
