FoamLogix, Model 2.1A and 1.7AHP Class “A”
Electronic Foam Proportioning Systems 29
SECTION 3 INSTALLATION
To simplify installation selection, one of the two
packages described in previous Section 2 should
be ordered. While either package provides most
of the components required for installation, the
following guidelines are offered to assist the system
installer with a complete system installation.
Carefully review the procedures that follow to
ensure the system is properly designed. This
section lists components that have been tested
with Hale FoamLogix and provide the best
system performance. Use of the recommended
materials and specified parts ensures a virtually
maintenance free installation.
Differences in apparatus plumbing and foam
system configuration make it impractical to show
exactly how the Hale FoamLogix 2.1A and 1.7AHP
systems are installed on a particular apparatus.
The informa tion contained in this section, however,
applies to most situations and should be used
when design ing and installing Hale FoamLogix
2.1A and 1.7AHP systems. A system plumbing and
electrical diagram is provided at the end of this
section to assist with installation.
Before proceeding with system installation,
carefully review the procedures that follow to
ensure the system is properly designed.
The Hale FoamLogix system is supplied with five
major components that must be located on the
apparatus.
❑
Foam pump and motor assembly
❑
Control unit
❑
Instruction/system diagram placard
❑
Flow Sensor
❑
Check valve injector fitting
Notes: The flow sensor and check valve
injector fitting may be pre-mounted, if a
manifold or pre-configured package is
ordered.
Optional components that require mounting on
the apparatus include:
❑
Mini Manifold
❑
Flanged elbows

WHEN DETERMINING THE LOCATIONS OF HALE
FOAMLOGIX COMPONENTS BEING INSTALLED
KEEP IN MIND PIPING RUNS, CABLE ROUTING
AND OTHER INTERFERENCES THAT COULD
HINDER OR INTERFERE WITH PROPER SYSTEM
PERFORMANCE.
FOAM PUMP AND MOTOR ASSEMBLY
The foam pump and motor assembly must be
located in an area that is protected from road
debris and excessive heat buildup. The back of a
compartment or a compartment shelf is often an
ideal location. The foam system, bypass valve,
strainer and shut-off valve are located on the foam
pump and motor assembly and access to these
components must be provided.
The foam pump and motor assembly must be
mounted below the discharge of the foam tank to
provide for gravity feed to the foam pump. The foam
tank must be located where refilling can be easily
accomplished with 5 gallon (19 liters) pails and other
methods suitable to the end user. Most water tank
manufacturers build the foam tank into the booster
tank.
When specifying a foam tank, make sure provi-
sions are made for:
