Auxiliary Foam Concentrate Intake Connection(s)
Every foam system shall be equipped with an auxiliary external foam concentrate connection intake. Such intakes
are commonly referred to as “OFF-BOARD” pick-up intakes. The final installer shall be responsible for the auxiliary foam
concentrate intake installation. Normally, this intake valve is located at or near the pump operator’s position, so that the
operator can easily see and control foam drafting or foam intake pressure.
The foam intake valve, plumbing, and adapters must be “sized” to the same size as the foam pump intake piping; supplied
by the final installer. An optional FoamPro FOAM-AUX system and Elkhart electric valve are available.
If specified by the end-user, the final installer shall supply an "off-board" foam suction hose, of a minimum of 10 feet /
3 meters in length. If longer, the intake hose shall be increased in hose diameter by one size. The intake line and suction hose
shall be the same size as the foam tank to foam pump line.
The end-user shall specify one of the following alternatives for an auxiliary foam intake valve(s):
a. “Suction only” intake use:
from foam totes, portable foam tank, or foam tanker supply, without a pressure and the
foam intake is for “suction only” purposes. A manual or electric gated ball valve sized to match the foam pump supply
inlet shall be installed. The intake valve, intake hose fittings and adapters shall be supplied by the final installer.
•
The final installer shall install the following warning label next to the foam intake valve and connection: this applies
only to FireLion and Edwards foam pumps.
•
Foam concentrate intake is intended for “suction ONLY” purposes. This foam intake shall NOT be used for “flushing”
foam system or pressurized foam supply.
