WATER AND FOAM SOLUTION
PLUMBING
When making water and foam solution
piping runs use the best industry practices to
install this piping. When making threaded
pipe connections use a suitable pipe
sealing compound at all joints.
OPTIONAL HALE PIPING COMPONENTS
Hale piping components such as 3 inch and
4 inch wafer type check valves, 115 and
2433 series flanges, mini and maxi
manifolds, etc. can simplify installation of
water and foam solution discharge piping.
The arrangement shown in figure 2-5
Hale FoamMaster System plumbing diagrams are located at the end of this manual
section. The diagrams provide recommended guidelines for the installation of system
components that handle water, foam concentrate and foam solution. The sequence in
which the plumbing installation is completed depends on the individual installation.
PLUMBING COMPONENT INSTALLATION
provides accurate proportioning across a
wide range for up to four discharges from
the mini manifold. The dual check valve
arrangement helps to ensure that no foam
concentrate will contaminate the pump
water. The Hale mini manifold provides a 1
inch NPT tap for installation of the check
valve/injector fitting. The Hale mini manifold
and elbow components use 4-
3
/
8
inch
diameter bolt circles and minimize
fabrication and pipe work. After installation
of the plumbing is complete make sure all
pipes, hoses and tubes are supported using
the best industry practices.
