3. Secure the bracket and strainer/valve assembly
to the apparatus.
4. Select the appropriate fittings from the bag at-
tached to the strainer assembly. Two of each fit-
ting are included with the strainer assembly. For
fitting selection vs. type of foam concentrate, re-
fer to
Figure 33 .
5. Coat all fitting threads with Permatex #80724 (or
equal) plastic pipe thread sealant. Install the fit-
tings into the strainer/valve assembly ends and
tighten.
6. Install the clear plastic hose from the foam tank
outlet to the inlet of the strainer/valve assembly
(
Figure 33 ). Wet the ends of the hose and fit-
tings to make the installation easier.
CAUTION!
MAKE SURE THE FOAM TANK AND FOAM CONCEN-
TRATE SUCTION HOSES ARE CLEAN BEFORE
MAKING FINAL CONNECTION TO FOAM PUMP. IF
NECESSARY, FLUSH THE TANK AND HOSES PRIOR
TO MAKING THE CONNECTION.
7. Install the clear plastic hose from the in-line
strainer/valve assembly outlet to the inlet of the
Hale MDT II, Hale MST, foam concentrate
pump, or the correct fitting on Hale ADT.
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 oper-
ating pressure of all other discharge plumbing compo-
nents (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 in-
let 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 correctly (
Figure
35 ).

3. Remove the strainer cap, mounting screws and
nameplate from the strainer assembly.
4. Mark holes for mounting the foam strainer by us-
ing the nameplate as a guide, or refer to Figure
36 .
5. Select the appropriate fittings to attach the
hoses to the strainer. Two of each fitting are in-
cluded 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” (19 mm) NPT x 3/4”
hose fittings. For FS-25 strainers use 1” (25 mm)
NPT x 1” hose fittings.
7. Coat all fitting threads with a suitable thread
sealant. DO NO USE Teflon Tape. Install the fit-
tings into the strainer/valve assembly ends and
tighten.
