For multiple gun installation, a fluid manifold may be used.
Fluid adjustments are made using the fluid control screw on
each gun. However, when precise fluid control is necessary,
a fluid regulator for each gun must be used.
1. Provide 50-60 PSI (minimum) air pressure for gun cylinder
operation.
2. Air line from gun to 3-way valve should be as short as
possible for maximum speed of operation.
3. Recommended hose sizes are 3/8" for fluid and 1/4" for air.
