: Installation
The base of the foam pump and motor
assembly has predrilled mounting holes.
These holes will accept
5
/
16
inch (8 mm)
diameter bolts and the apparatus mounting
location needs to be drilled accordingly.
The base plate can be used as a template
to mark mounting hole location or a
mounting hole layout drawing is provided
as figure 2-4.
Make sure the foam concentrate hoses can
be properly routed to the inlet and outlet on
the foam pump. Foam concentrate must
gravity feed to the foam pump inlet from
the foam tank(s). The foam pump must be
mounted in an area to avoid excessive
engine exhaust system or accessory heat
buildup.
