concentrates deteriorate rapidly, and residue cannot be left
in the lines.
Note: Approved Class “A” foam concentrates do not deteri-
orate rapidly like Class “B” concentrates. As long as an ap-
proved 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 FLUSH
the system, then switch back to Class “A” (Figure 69 and
Figure 74).
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.

3. Place the Hale ADT, MDT II or MST to the FLUSH
position (Figure 74).
4. Observe the discharge hose and allow Hale Smart-
FOAM 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 capa-
ble 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 ca-
pable 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.
