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 FoamMaster system by
pressing the red
ON
button. The
ON
button will illuminate to indicate the
system is on and the bargraph indicates
whether foam concentrate is being
pumped. If no concentrate is flowing
the pump will increase to maximum
speed in an attempt to prime itself. 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.
