PREPARATION AND PRIMING OF PREVIOUSLY USED
(shut down) SYSTEM
1. Slowly open main air.
2. Material Pump: (be sure catalyst pump is disengaged) Place a container or
bucket under ball valve located at the bottom of the resin filter assembly to catch
material while priming. Open ball valve. Slowly bring up pressure on material
pump regulator just enough to allow pump to stroke up and down evenly. After a
smooth flow of material is flowing from the valve, turn regulator off and close the
valve.
3. Catalyst Slave Pump:
a. Disengage slave pump.
b. Open ball valve of catalyst manifold (if applicable).
c. Eliminate all air pockets in feed lines by manually pumping catalyst pump
until catalyst exits ball valve. Close ball valve.
e. Open gun by pulling trigger and continue hand pumping until catalyst exits
gun.
f. Leave Catalyst Pump disengaged.
4. Pull trigger on gun and allow gun to hang above waste container. Slowly bring up
pump pressure again to allow material to flow out of gun. Release trigger to close
gun. Pump will cycle until it is fully primed and then will stall out.
6. Engage slave pump.
