Air is not allowed to flow into the discharge unless water flow and pressure
are available. The Hale FoamLogix system is activated and starts the foam
concentrate injection when the air compressor is engaged. This important
safety enhancement feature helps to prevent “slug flow” or air and water
only from being discharged into the hose line. If the water pump is not
primed, or the Hale FoamLogix foam system is OFF or out of foam, the Hale
CAFSPro control does not allow air injection.
When water and foam concentrate are properly supplied, the Hale CAFS-
Pro air flowmeter safety interlock allows air to flow into the CAFS capable
discharge.
WARNING !
WITH WATER IN THE FOAM TANKS, THE OPERATOR IS PROPORTIONING
WATER INTO THE DISCHARGE STREAM AND SLUG FLOW CAN RESULT.
ALWAYS SELECT THE FOAM TANK PRIOR TO STARTING OPERATIONS,
WHEN THE APPARATUS IS EQUIPPED WITH A DUAL FOAM TANK SYSTEM.
ENSURE THE FOAM TANK CONTAINS AN APPROVED FOAM CONCEN-
TRATE. (SEE APPENDIX A “FOAM CONCENTRATE COMPATIBILITY,”
BEGINNING ON PAGE 67.)
DO NOT USE WATER IN THE FOAM TANKS!
