Five seconds after system activation the tank-to-pump valve can be oper-
ated manually – CLOSED by the operator. When a CAFS line is pulled and
its corresponding discharge valve is opened, compressed air foam is avail-
able at CAFS hose line.
Adjusting foam consistency from extremely WET to “shaving cream DRY” is
done by pressing the WET or DRY ARROW buttons (to adjust the air-to-
water ratio). The system starts at WET attack CAFS foam of 0.5 SCFM air
to 1.0 GPM (3.8 LPM) solution.
However, it is important to note that the Hale CAFSPro uses a three-setting
valve to create its wide range of foam types. When adjusting from the WET
to MEDIUM range, the system beeps three (3) times. To make sure the sys-
tem changes over to MEDIUM, the operator must hold down the button for
the full duration of three beeps.
The available water volume through the foam manifold is reduced from
1,000 GPM (3,785 LPM) to about 300 GPM (1,136 LPM). Note that this
affects all Compressed Air Foam lines.
Also when moving from the MEDIUM to DRY, the total water volume from all
compressed air foam lines drops to around 30 GPM (114 LPM).
WARNING !
IT IS IMPERATIVE NEVER TO CHANGE TO “DRY FOAM” IF FIREFIGHTERS
ARE ATTACKING A FIRE WITH A CAFS HOSE LINE. THE TOTAL VOLUME
FROM ALL THE CAFS LINES COMBINED IS NO MORE THAN 30 GPM (114
LPM). USE THE “DRY” MODE ONLY WHERE APPROPRIATE, AND FIRE
FIGHTER SAFETY WILL NOT BE COMPROMISED.
EXTREMELY DRY FOAM IS TYPICALLY USED FOR A SINGLE HAND LINE
FOR EXPOSURE PROTECTION OR SOMETIMES FOR OTHER NON-FIRE
ATTACK USES.
DRY FOAM CONTAINS VERY LITTLE WATER CONTENT AND IS NOT REC-
OMMENDED FOR MULTIPLE LINE USE OR DIRECT FIRE ATTACK.
For foam solution only without air, set the air compressor in the STANDBY
mode. Press the POWER button for about one (1) second until it beeps
once. The air injection valve CLOSES and all compressed air foam lines
become foam solution lines. The indicator light, under the ON button turns
OFF.
Pressing the POWER button again shifts the CAFS system out of
STANDBY to resume normal CAFS operations. This indicator light turns
ON to indicate the system status.
