3. Place the system in simulated flow mode
by selecting the FLOW display and
depressing both up
é and down ê
buttons simultaneously. Increase
simulated flow value by pressing
é
button to permit easier priming (above
factory default value of 150 GPM).
Display will show “
S ” at the left most
position to indicate the simulated flow
(See figure 3-2).
4. Engage the Hale FoamLogix system by
pressing the red ON button. The left LED
on the horizontal bargraph will illuminate
to indicate the system is on. As the foam
pump begins to run the bargraph LEDs
to the right light indicating foam
concentrate is being pumped. If no
concentrate is flowing the pump will
increase to maximum speed in an
attempt to prime itself. All LEDs will light
and flash. The pump will run at full
speed until a feedback signal is
indicated or for 30 seconds. If no
feedback signal is present after 30
seconds the system will shut down and
the display will show "
noPri " (no prime).
Repeat this step one more time to
attempt to prime the pump.
If the foam pump does not prime after
the second try do the following:
• Make sure all foam concentrate
valves are open.
• Make sure there are no restrictions in
the hose from the foam concentrate
tank to the inlet of the foam pump.
• Make sure there are no air traps in
the hose from the foam concentrate
tank to the inlet of the foam pump.
• Make sure there are no leaks in the
plumbing where air can enter the pump.

5. If the system has been installed
properly, foam concentrate should flow
readily to the pump. Observe the clear
foam suction line to verify if foam is
flowing.
6. If a dual tank system is installed switch
to TANK B and repeat priming
procedure for that tank.
7. Once foam flow is established from
both tanks, turn the system off and turn
the bypass valve back to the INJECT
position.
Proceed with user calibration procedures
as system calibration must now be verified
with the end user foam concentrate.
