FoamLogix, Model 2.1A and 1.7AHP Class “A”
Electronic Foam Proportioning Systems

❑
Foam suction connections
❑
Tank drainage
❑
Proper fill openings, per NFPA requirements.
In addition, a foam tank refill system may
be required. See Hale EZFill system for
installation requirements.
CONTROL UNIT AND INSTRUCTION/
SYSTEM DIAGRAM PLACARD
Determine a location on the operator panel of the
apparatus for the control unit and instruction/ system
diagram placard, if provided. These components
must be located at the main pump operator position
in close proximity to each other. Consideration
must be given for routing the control cable from the
control unit to the distribu tion box on the foam pump
and motor assembly. If necessary, order longer
or shorter cable as semblies to suit the location
demands.
INSTALLER SUPPLIED COMPONENTS
Due to the many differences in apparatus con-
figurations and design requirements the Hale
FoamLogix system installer must supply compo-
nents, such as,
❑
mounting brackets
❑
piping
❑
hoses
❑
fittings
❑
electrical wiring
❑
foam tank(s)
The following guidelines are recommendations for
selection of additional components for a complete
system installation. These recommen dations
reflect materials and components that are tested
extensively with Hale FoamLogix systems and
provide proven reliable performance.
Foam Concentrate Suction Hose
The Hale FoamLogix 2.1A and 1.7 AHP Foam
systems are provided with 15’ (4.6 meters) of 1/2”
(13mm) ID reinforced PVC foam concentrate suction
hose. The system installer may need to supply
additional fittings and hose from the foam tank to the
inlet of the foam pump.
All components selected transfer foam con centrate,
therefore they must be compatible with the foam
concentrates being used in the system. Hoses for
Class A foam concen trates have minimum 1/2”
(13mm) inside diameter.
Hoses for the foam concentrate suction must have
a rating of 23” (584 mm) Hg vacuum and 50 PSI
(3.5 BAR) pressure or greater.
Note: NFPA requires that foam concentrate suction
hose be clear to observe foam concentrate flow
during foam pump operation.
Recommended Components
❑
Hose: PVC, Kuriyama Kuri-Tec K3130 or K7130
series
❑
Fittings: Hose Barb Type; Brass, Stainless
Steel or Nylon
A tee with foam tank shut-off valve and a drain
valve is recommended in the foam tank suction
hose to allow, tank drainage and easier priming.
These components are subject to the same material
characteristics and pressure ratings as stated
above.
The foam concentrate strainer includes a shut-
off valve. This valve is used to shut off foam
concentrate flow to service the strainer.
