Magnum Venus Plastech Gel Coat Gun EMG-1500 - Manual (Page 10)

PREPARATION AND PRIMING OF “NEW” SYSTEM
1. Be sure all air regulators are turned completely to the left, shutting off air to the
components.
2. Slowly open main air.
3. Prime empty catalyst line:
a. Disengage catalyst pump
b. Open ball valve on catalyst manifold (if applicable)
c. Eliminate air pockets by manually hand pumping the catalyst 5-10 short
strokes (2-3 in.). After eliminating air pockets, and while continuing to
hand pump, close ball valve on catalyst manifold.
d. Pull and hold trigger on gun while hand pumping catalyst pump with short
strokes until there is a solid, steady catalyst flow from the head of the gun.
This will ensure that all air is purged from the line. Release trigger.
e. Continue to hand pump the catalyst with short strokes until catalyst is fully
primed and pressurized (generally within 5 additional strokes or less).
NOTE: Do NOT engage slave pump until material pump has been primed.
4. 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.
5. 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.
