SmartFOAM
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 compo-
nents that have been tested with Hale SmartFOAM and
provide the best system performance. Use of the recom-
mended materials and specified parts ensures a virtually
maintenance free installation.
Differences in apparatus plumbing and foam system con-
figuration make it impractical to show exactly how the Hale
SmartFOAM systems are installed on a particular appa-
ratus.
The information contained in this section, however, applies
to most situations and should be used when designing
and installing Hale SmartFOAM systems. A plumbing and
electrical diagram is provided at the end of this section to
assist with installation.
Before proceeding with system installation, carefully re-
view the procedures that follow to ensure the system is
properly designed.
The Hale SmartFOAM system is supplied with five major
components that must be located on the apparatus:
❑ Foam pump motor and assembly
❑ Control unit
❑ Instructions/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 pack-
age is ordered.
Optional components that require mounting on the appa-
ratus include:
❑
Mini manifold
❑
Flanged elbows
❑
Manual Single Tank (MST) selector valve
❑
Manual Dual Tank (MDTII) selector valve
❑
Air Dual Tank (ADT) operating switches and indi-
cator lights
❑
Foam tank(s)
❑
FS Series panel mounted foam strainers
❑
Remote activation switch and indicator
❑
SAM Green CAN bus harness
IMPORTANT!
WHEN DETERMINING THE LOCATIONS OF HALE
SMARTFOAM COMPONENTS BEING INSTALLED KEEP
IN MIND PIPING RUNS, CABLE ROUTING AND OTHER
INTERFERENCES THAT COULD HINDER OR INTER-
FERE 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
build-up. 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 (excluding the con-
verter) 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 accom-
plished with 5 gallon (19 liter) pails and other methods suita-
ble to the end user. Most water tank manufacturers build the
foam tank into the booster tank.
When specifying a foam tank, make sure provisions are
made for:
❑
Installation of the low tank level sensor
❑
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.
FOAM CONCENTRATE STRAINER
Determine a location on the apparatus to mount the foam
strainer.
CAUTION!
THE IN-LINE STRAINER/VALVE ASSEMBLY IS A LOW
PRESSURE DEVICE THAT WILL NOT WITHSTAND
FLUSHING WATER PRESSURE. WHEN INSTALLING
THE IN-LINE STRAINER IN SYSTEMS EQUIPPED WITH
HALE “MDT II” OR HALE “MST,” MAKE SURE THE IN-
LINE STRAINER/VALVE ASSEMBLY IS IN THE HOSE ON
THE INLET SIDE OF THE VALVE.
IF THE STRAINER IS SUBJECT TO FLUSHING WATER,
USE HALE “FS” SERIES STRAINERS.
Mount the in-line foam strainer/valve assembly in the foam
concentrate hose from the foam tank to the foam pump suc-
tion connection, ADT, MDT II or MST.
