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.

GENERAL NOTES
1. Have at least 35 PSI air pressure for cylinder operating air.
2. The air line from spray gun to 3-way valve should be as
short as possible for rapid operation.
3. All air used in the spray gun should be dirt and moisture
free. (This is accomplished by using a clean air filter.)
4. Shut off all fluid and air lines to spray gun if spray gun is
to stand idle for any length of time. (This is to prevent
"build-up" or accumulation of minute leaks in the system.)
5. Generally fluid hoses are 3/8" and air hoses are 1/4".
