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
components that have been tested with Hale SmartFOAM
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 SmartFOAM systems are installed on a particular
apparatus.
The information contained in this section, however, applies
to most situations and should be used when designing
and installing Hale SmartFOAM 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 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
package is ordered.
Optional components that require mounting on the
apparatus include:
❑
Mini manifold
❑
Flanged elbows
❑
Manual Single Tank (MST) selector valve
❑
Manual Dual Tank (MDTII) selector valve
❑
Air Dual Tank (ADT) operating switches and
indicator lights
❑
Foam tank(s)
❑
FS Series panel mounted foam strainers
❑
Remote activation switch and indicator
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
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
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 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 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
PRESSURE, 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
suction connection, ADT, MDT II or MST.
