WARNING !
THE LOW PRESSURE CAFS LINES OPERATE AT PRESSURES OF APPROXI-
MATELY 150 PSI (10 BAR). ALL FITTINGS, TUBING, ETC. USED MUST BE
RATED FOR THE MAXIMUM CAFS SYSTEM DISCHARGE OPERATING
PRESSURE.
LOW PRESSURE LINES MUST ALSO BE ADEQUATE FOR OPERATING
TEMPERATURES FROM -30° F TO +140° F (-34° C TO +60° C).
2. Provisions must be made to include a check valve in each line to prevent water
/ foam solution from back-flowing and contaminating the air lines.
For best performance, the check valves (2) must be mounted right after the
main HIGH pressure shut-off valves. (See Figure 4-10: “Typical LOW Pressure
CAFS Air Connections.”)
