: Installation
the inlet connection port is oriented as
shown in figure 2-14 when installing the
FS series strainer.
2. Remove the strainer cap, mounting
screws and nameplate from the strainer
assembly.
3. Using the nameplate as a guide, or refer
to the diagrams in figure 2-15, mark
holes for mounting the foam strainer.
The holes for the FS15 strainer mounting
screws are 9/32 inch (7 mm) and the
holes for FS25 strainer screws are 11/32
inch (9 mm) diameter. Additionally a
hole of sufficient size for the cap threads
to clear the panel is required. [FS15
strainer 2.13 inches (54 mm) and FS25
strainer 3.38 inches (86 mm)]
4. Select appropriate fittings for
attachment of the hoses to the strainer.
The fittings and hoses chosen 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)].
When using an FS15 strainer use ¾ inch
NPT x ¾ inch hose fittings.
When using an FS25 strainer use 1 inch
NPT x 1 inch hose fittings.
Before assembly coat all fitting threads
with a suitable thread sealant. Install the
fittings into the strainer and tighten
securely.
5. Make sure the strainer is oriented as
shown in figure 2-14 and secure the
strainer body and nameplate to the
apparatus with the screws provided.
Install the cap on the strainer.
