the bracket to the apparatus. Secure
the bracket and strainer/valve assembly
to the apparatus.
3. Select the appropriate fittings from the
bag attached to the strainer assembly.
Two of each fitting are included with the
strainer assembly.
For Class A foam concentrate use the
supplied 1-1/4 inch NPT x ¾ inch hose
fittings in each end of the strainer/valve
assembly.
For most Class B foam concentrates use
the 1-1/4 inch NPT x 1 inch hose fittings.
When using higher viscosity Class B ATC
concentrates use the 1-1/4 inch NPT x 1-
1/4 inch hose fittings
Before assembly coat all fitting threads
with Permatex #80724 (or equal) plastic
pipe thread sealant. Install the fittings
into the strainer/valve assembly ends
and tighten securely.
4. Install the clear plastic hose from the
foam tank outlet to the inlet of the
strainer/valve assembly. The inlet of the
strainer/valve assembly is on the valve
end. Wetting the ends of the hose and
fittings will make the installation on the
hose fittings easier.
CAUTION: Make sure the foam tank and
foam concentrate suction hoses are
clean before making final connection to
foam pump. If necessary flush tank and
hoses prior to making connection.
5. Install the clear plastic hose from the in-
line strainer/valve assembly outlet to the
