SmartFOAM
FLUSHING THE SMARTFOAM SYSTEM
When returning the apparatus to the ready condition after
foam operations
using Class “B” foam, the Hale SmartFOAM
foam pump must be FLUSHED.
Some Class “B” foam
concentrates deteriorate rapidly and residue cannot be left in
the lines.
Note :
Approved Class “A” foam concentrates do not
deteriorate rapidly like Class “B” concentrates. As long as an
approved Class “A” foam concentrate is used and the
system is operated within 10-12 weeks no flushing is
required. When Class “B” foam concentrate is used, always
FL
USH the system, then switch back to Class “A” (see
Figure 56 : Dual Tank Selector Operating Positions and
Figure 58 : Hale MST Selector Operation ).
1. Energize the apparatus and establish water flow
through a foam capable discharge. Set the fire pump
for a LOW discharge pressure, 50 to 75 PSI (3.4 to
5.2 BAR).
2. Energize the Hale SmartFOAM by pressing the ON
button, allowing foam solution to discharge.
Note : When the Hale ADT, MDTII or MST is in the
FLUSH position the Hale SmartFOAM foam injection
system runs for about twenty (20) second.
Figure 58 : Hale MST Selector Operation
3. Place the Hale ADT, MDT II or MST to the FLUSH
position (see Figure 58 : Hale MST Selector
Operation ).
4. Observe the discharge hose and allow Hale
SmartFOAM and discharge to run for several
seconds.
5. After several seconds place the Hale ADT or MDT II
to the TANK “A” position and allow the system to run
until all foam solution is discharged through the
foam capable hose line.
Note
: When the Hale MST is used for Class “B”
foam concentrates DO NOT allow the foam pump to
run in the FOAM TANK position after flushing foam
pump.
6. Place the Hale MST to the FOAM TANK position
and allow Hale SmartFOAM
to run until Class “A”
foam solution is discharged through the foam
capable hose line. If Class “B” foam concentrate is
used, shut down Hale SmartFOAM immediately
after switching to the FOAM TANK position.
7. Shut down Hale SmartFOAM allowing the foam
capable discharge to continue to flush out the fire
pump discharge manifold as required. Once clear
water flows, close foam capable discharge and shut
down the apparatus.
8. Perform required maintenance checks on the Hale
SmartFOAM and apparatus to return the apparatus
to the ready condition.
IMPORTANT!
MAKE SURE THE HALE ADT OR MDT II IS IN THE TANK
“A” POSITION AND THE HALE MST IS IN THE FOAM
TANK POSITION WHEN APPARATUS IS PLACED IN THE
READY CONDITION.
