IMPORTANT:
When determining the
locations of Hale FoamMaster
components being installed keep in
mind piping runs, cable routing and
other interferences that will hinder or
interfere with proper system
performance.
FOAM PUMP and MOTOR ASSEMBLY:
Ideally
the foam pump and motor assembly should
be located in an area that is protected
from road debris and excessive heat
buildup. The foam system master power
switch and bypass valve are located on the
foam pump and motor assembly and
access to these controls must be provided.
It is recommended that the foam pump
and motor assembly be located in a
protected area but, foam concentrate
gravity feed requirements or apparatus
design limitations may necessitate locating
the foam pump and motor assembly on a
shelf in the apparatus pump house or
attached to the apparatus frame. The
motor and electrical components are
designed to withstand the harsh
environment encountered in an emergency
apparatus environment.
Differences in apparatus plumbing and
foam system configuration make it
impractical to show exactly how each Hale
FoamMaster system is installed on a
particular apparatus. The information
contained in this section, however, will
apply to most situations and should be used
when designing and installing a Hale
FoamMaster system. System plumbing and
electrical diagrams are provided at the end
of this installation section to assist the
apparatus manufacturer with installation of
the Hale FoamMaster system.
The following subsections provide the
system installer with guidelines for a
complete system installation. Before
proceeding with system installation carefully
review the procedures that follow to ensure
the system is properly designed. The
subsection titled
Installer Supplied
Component Recommendations
lists those
components that have been tested with
Hale FoamMaster and provide the best
system performance. Use of the
recommended materials and specified
parts will ensure a virtually maintenance
free installation.
The Hale FoamMaster system is supplied
with six major components that must be
located on the apparatus. The major
components of the Hale FoamMaster
system are:
Foam pump and motor assembly
Control unit
In-Line foam strainer/valve assembly
Instruction/system diagram placard
HPF flowsensor
Check valve injector fitting
Optional components to enhance system
installation and operation that require
mounting on the apparatus include:
