SmartFOAM
Align the indexing pin of the saddle clamp to the
indexing hole of the spacer to align the saddle clamp
mount.
Secure with four
1/2” machine screws, no lock washers.
Torque to 8.5 in.-lbs. (1.0 N-m).
Align the paddle wheel indexing pin to the indexing hole
in the spacer and secure using four
3/4” screws and lock
washers. Torque to 7.5 in.-lbs. (0.9 N-m).
Apply a small amount of grease to the saddle clamp
gasket before the final installation of the assembly onto
the pipe. Firmly tighten the saddle clamp onto the pipe.
FOAM PUMP FLUSH SYSTEM
Dual Tank System
Flushing water must be provided to flush the system of
foam concentrate after each use. This prevents adverse
reactions of some foam concentrates should they mix
together. The Hale ADT and MDT II each have
provisions for connecting flushing water to the foam
concentrate injection system.
Single Tank System
The Hale MST provides a selector valve and gives the
system flush capabilities for NFPA compliance. A fitting
provided on the Hale MST simplifies the flushing water
connection.
No Tank Option
The system installer must provide a flushing water
supply to comply with NFPA standards.
The flushing water hose must be a minimum of 1/2” (12
mm) inside diameter and capable of withstanding the
maximum fire pump discharge pressure, 500 PSI (34
BAR) minimum. The flush water supply should be
provided from one of the pressure taps on the discharge
of the fire pump.
It is recommended that a check valve be installed at the
pressure tap to prevent contamination. Flush water
thread connections are:
❑
ADT -
1/2” (13mm) NPT
❑
MDT II and MST -
1/4” (6.4mm) NPT
The system installer must provide proper fittings for
these connections.
FOAM CONCENRATE PLUMBING
CAUTION!
MAKE SURE THE FOAM TANK AND FOAM
CONCENRATE SUCTION HOSES ARE CLEAN
BEFORE MAKING A FINAL CONNECTION TO FOAM
PUMP. FLUSH TANK(S) AND HOSES PRIOR TO
MAKING CONNECTIONS. MAKE SURE THE FOAM
CONCENRATE IS GRAVITY FED FROM THE TANK
TO THE PUMP.
Foam concentrate plumbing consists of:
❑
Foam concentrate suction hose
❑
Foam strainer
❑
Foam concentrate discharge hose
❑
Check valve/injector fitting
FOAM STRAINER CONNECTION
CAUTION!
THE FOAM CONCENTRATE STRAINER ASSEMBLY,
MOUNTED ON THE FOAM PUMP INLET, IS A LOW
PRESSURE DEVICE. IT WILL NOT WITHSTAND
FLUSHING WATER PRESSURE. IF FLUSHING
WATER IS TO BE PROVIDED THE PRESSURE MUST
BE LIMITED TO 50 PSI (3.5 BAR).
The strainer/valve assembly has
1/2” (12mm) NPT
female threaded ports. A
1/2” hose barb fitting is
supplied to connect the
1/2” ID hose, provided with the
Hale SmartFOAM 2.1A installation kit.
The hose from the foam tank to the strainer must have
adequate wall stiffness to withstand the vacuum of the
foam pump while it is operating (23” [584 mm] Hg and
50 PSI [3 BAR], Kuriyama, Kuri-tec K-3130 or K-7130
series or equal).
After the foam pump is mounted on the apparatus,
connect the PVC hose provided to the strainer inlet.
Install the clear plastic hose from the foam tank outlet to
the inlet of the strainer/valve assembly. The inlet is on
the valve end. Wetting the ends of the hose and fittings
makes the installation on the hose fittings easier.
CAUTION!
MAKE SURE THE FOAM TANK AND FOAM
CONCENTRATE SUCTION HOSES ARE CLEAN
BEFORE MAKING FINAL CONNECTION TO FOAM
PUMP. IF NECESSARY FLUSH TANK AND HOSES
PRIOR TO MAKING CONNECTION.
