THE HIGH PRESSURE SIDE IS BLED (PRESSURE RELIEVED) BY FIRST MAK-
ING SURE THE CYLINDER SHUT-OFF VALVE IS FULLY CLOSED. THEN
SLIGHTLY LOOSENING THE HOSE FITTING NUT AT THE CYLINDER SHUT-
OFF VALVE UNTIL YOU HEAR AIR ESCAPING FROM THE FITTING. AN
ALTERNATE METHOD IS TO INSTALL AND SHUT-OFF VALVE IN AN ACCES-
SIBLE AREA IN THE HIGH PRESSURE LINE. ALSO SEE HEADING “RELIEV-
ING HIGH PRESSURE” ON PAGE 59.
❑ All LOW discharge pressure air lines are the proper size and type and all
connections are tight.
WARNING !
ONCE THE CYLINDERS ARE FULLY CHARGED AND THE SYSTEM IS ENER-
GIZED, THE DISCHARGE (LOW) PRESSURE LINES ARE EXPOSED TO LOW
PRESSURE (APPROXIMATELY 150 PSI / 10 BAR).
THE DISCHARGE LINES ARE BLED (PRESSURE RELIEVED) BY OPENING
THE CONDENSATION DRAIN VALVES.
❑ The water line from the midship pump the pressure balancing regulator
valve dome port is the proper size and type and the connections are
tight.
❑ Flow sensor mounted with flow arrow in the correct direction for water
flow.
❑ Check valves are properly mounted in air lines. (See Figure 4-10: “Typi-
cal LOW Pressure CAFS Air Connections,” on page 36.) Also see Figure
4-5: “Typical CAFSAttack SVS Discharge Manifold Assembly” on page
30.
❑ Air filter/strainer mounted for proper air flow direction.
❑ All hoses are free of kinks and sharp bends. No sharp bends exist that
