Pressurizing Fluids:
NOTE: On the air manifold, the blue valve is the safety override. The small brass
button next to the valve is the priming button.
The Gel coater Unit is standard with a safety override valve. This valve automatically
opens and closes the air supply to the pump air motor. The safety valve will be opened
when the gun trigger is opened or when the priming button is pushed.
NOTE: Remove catalyst pivot pin before pressurizing gel coat to the pump. Do
not reinstall pivot pin at this time / open the catalyst recirculation valve at the
catalyst manifold to prevent over pressurizing the catalyst system.
1.
Push on the priming button and slowly increase the gel coat pump regulator: 40 to
50 psi would be a starting point.
2.
Using the catalyst drive arm, use slow up and down motion to pressurize the
catalyst pump.
External Mix: Prime a little pressure
– there is no gauge on this system.
Internal Mix: Prime to 200psi to 400psi. There should be a gain in pressure on
both the up and down strokes
– watch the catalyst pressure gauge.
3.
Pin the catalyst drive into the pivot arm. Set desired catalyst percentage.
Gun Set-Up
Internal Mix:
Note: Use a little red grease on the o-rings and threads before installing the spray
tip, catalyst tip and retainer.
1.
Install turbulent mixer into mix chamber. Insert static mixer and spray tip onto the
air assist housing. Screw air-assist onto the gun mix housing. For longer turbulent
mixer life, do not over tighten the air assist nozzle housing.
2.
Attach air assist tube from needle valve on side of gun handle to air-assist head.
3.
Spray test pattern; make gel coat pump pressure adjustment until a fairly uniform
pattern is achieved. There should be slight horns on either side of the spray fan.
Slowly open the air-assist needle valve located on the side of the gun handle until
a soft uniform pattern is achieved.
