5A.2 SHUTTING-DOWN CAFSATTACK
IMPORTANT !
WHEN CAFS OPERATION IS COMPLETE, SET THE AIR BOTTLE VALVE HAN-
DLE TO THE CLOSE (O) POSITION.
DANGER !
NEVER FULLY EMPTY THE CAFSATTACK AIR CYLINDERS. ALWAYS MAIN-
TAIN POSITIVE PRESSURE IN THE CYLINDERS TO PREVENT MOISTURE
AND/OR DIRT CONTAMINATION. AN INDICATION OF A “LOW” CHARGE IN
TO AIR BOTTLES IS WHEN THE BOTTOM LIGHT ON THE INTELLI-TANK DIS-
PLAY FLASHES.
NEVER LEAVE THE AIR BOTTLE SHUT-OFF “OPENED” WHEN THE SYSTEM
IS NOT IN OPERATION.
5A.3 EMERGENCY SHUT-DOWN
Should an emergency shut-down be required in the event of a:
❑ System electrical power loss
❑ Electrically-operated valve malfunction - sticking valve that does not
open or close properly, valve opened when it should be closed providing
air in lines when not wanted, etc.
❑ Loss of foam - empty tanks, valve malfunction, FoamLogix system mal-
function, etc.
❑ CAFS is always enabled, does not shut-down
❑ Any other system malfunction that produces a dangerous operating
condition
1. Manually shut-off the air supply to the system - turn the CAFS-
Attack air bottle valve, on the operator’s control panel, to the
CLOSE position (O).
2. Set the CAFS ENABLE switch, on the operator’s control panel, to
OFF (O).
3. Close the air bottle shut-off valves on each cylinder.
