FS Series Strainer
When a pressurized water flush is provided to the strainer from one of the
discharges, Hale FS series strainers are required. The plumbing exposed
to the flush water pressure must be rated at or above the operating pressure
of all other discharge plumbing components (500 PSI/34 BAR minimum).
To Install FS Series Strainers
1. Choose a location on the apparatus that allows gravity feed from the
foam tank to the strainer inlet and from the strainer outlet to the foam
pump suction connection.
2. When selecting the
strainer location
make sure there is
sufficient space
behind the pump
panel to attach
hoses and fittings.
Also make sure the
inlet connection port
is oriented cor-
rectly. (See Figure
3-16: “FS Strainer
Orientation.”)
3. Remove the strainer cap, mounting screws and nameplate from the
strainer assembly.
4. Mark holes for mounting the foam strainer by using the nameplate as a
guide, or see Figure 3-17: “FS Strainer Mounting Dimensions” on page
70.
5. Select the appropriate fittings to attach the hoses to the strainer. Two of
each fitting are included with the strainer assembly. The fittings and
hoses must be capable of withstanding the vacuum generated by the
foam pump (23 inches [584 mm] Hg) and the maximum flushing water
pressure (500 PSI [34 BAR]).
6. For FS-15 strainers use 3/4” (19mm) NPT x 3/4” hose fittings. For FS-
25 strainers use 1” (25mm) NPT x 1” hose fittings.
7. Coat all fitting threads with a suitable thread sealant. DO NO USE
Teflon Tape. Install the fittings into the strainer/valve assembly ends and
tighten.
