Figure 2-9: Panel Mounted Strainer / External Pick-Up Connection

A bronze body strainer / connector unit is mounted on the pump panel. The external foam pick-up consists of one
(1) 1 in. male connection with chrome-plated cap, integrated to a 2 in. strainer clean-out cap. A check valve is
installed in the pick-up portion of the clean-out cap. A basket style stainless steel screen is installed in the body of
the strainer / connector unit.
The strainer is used to prevent any debris from entering the foam system and possibly interfering with the internal
foam pump check valves.
Removal of the 2 in. clean-out cap is all that is required to gain access to and remove the stainless steel basket
screen. The strainer / connector is located ahead of the foam concentrate pump inlet port, to insure that all agent
reaching the foam pump has been strained.
The external foam pick-up permits the use of a foam agent that is not stored on the vehicle. The external foam pick-
up also allows continued operation after the on-board foam tank is empty. The external foam pick-up can also be
used with training foam or colored water for training purposes.
This connection also functions as the Class A tank fill
(when equipped with tank fill option)
and as the foam tank
drain.
