IMPORTANT: When determining the
locations of Hale FoamLogix
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 foam pump and motor assembly should
be mounted below the discharge of the
foam tank(s) to provide for gravity feed to
the foam pump. The foam tank(s) must be
located where refilling can be easily done
with 5 gallon (19 liter) pails and other
methods suitable to the end user. Most
water tank manufacturers will build foam
tanks into the booster tank. When
specifying foam tank(s) make sure
provisions are made for installation of the
low tank level sensor as well as foam suction
Differences in apparatus plumbing and
foam system configuration make it
impractical to show exactly how each Hale
FoamLogix 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 FoamLogix
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
FoamLogix 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 FoamLogix and provide the best
system performance. Use of the
recommended materials and specified
parts will ensure a virtually maintenance
free installation.
The Hale FoamLogix system is supplied with
six major components that must be located
on the apparatus. The major components
of the Hale FoamLogix system are:
Foam pump and motor assembly
Control unit
In-Line foam strainer/valve assembly
Instruction/system diagram placard
Flowsensor
Check valve injector fitting
Optional components to enhance system
installation and operation that require
mounting on the apparatus include:
FS15 or FS25 panel mounted foam
strainer
ADT operating switch and indicator lights
