CAFS Air LOW Pressure Gauge Layout Option
An “optional” numeric-display, low or CAFS air pressure gauge is available,
Class1 p/n: 91220001, to show the air pressure being delivered to the foam
discharge manifolds. (See Figure 4-13: “CAFS Air LOW Pressure Layout
Option,” on page 38.)
The gauge should be mounted in the area of the CAFSAttack operator’s
panel and plumbed in the system after the pressure balancing regulator
valve. Use 1/4” (6 mm) DOT approved tubing and 1/4” brass fittings.

Use a suitable sealing compound (for example, Loctite PST) on all fitting
threads.

A system electrical diagram is provided at the end of this manual. Refer to
this diagram for proper installation of the electrical components.
The Class1 CAFSAttack system is designed to be installed with a minimum
of electrical connections. A main harness cable assembly is provided with
each system to enable the flow sensor, electric valve motors and transducer
connections.
The system installer must supply primary power and ground wiring. Also
