For your safety, Hale has designed a self-bleed mechanism into the CAFS
manifold. As a precaution against air-energized manifolds, when the pump
is switched back to ROAD, the CAFS manifold drains itself, then the drain
automatically closes. The manifold is still WET and can even contain some
residual pressure, but the higher pressures and stored energy have been
safely drained to the ground.
Note: Every time the pump is shifted back to ROAD, a small discharge of water
solution is drained under the truck.
In addition, numerous electronic and mechanical safety features have been
designed into the CAFSPro as follows:
❑ If the FoamLogix detects a loss of foam concentrate prime resulting in no
concentrate flowing into the foam manifold, it automatically disengages
the air injection to prevent “slug flow.”
❑ “Low foam” flashes if FoamLogix detects that there is a dangerously low
level of concentrate in the foam reservoirs.
❑ If the FoamLogix is accidentally powered OFF, or the operator turns OFF
the foam injection system before the air injection system, the air injection
system automatically is disengaged to prevent “slug flow.”
❑ The compressed air injection system’s safety features are to alert the
operator of:
● Dangerously high compressor temperatures
● Dangerously high rotary compressor speed. If the operator over-revs
the throttle, a warning will flash and sound.
❑ If the operator continues to increase speed, the compressor disengages.
CAFSPro systems must not be run above 150 PSIG. This eliminates
most high speed issues.
