: Set-up and Calibration
When the apparatus is delivered to the end
user facility the foam tank(s) must be filled
with the specified foam concentrate(s).
Make sure the proper foam concentrate is
put into the correct tank. The system must
then be adjusted to operate with the end
user foam concentrate(s) for best
accuracy.
SYSTEM POWER CHECK
Observe the display on the control unit
while energizing the apparatus electrical
system and turn the foam pump distribution
box power switch to
ON
. Check the control
unit readout —
FLOW, TOTAL FLOW, %
FOAM, TOTAL FOAM, ON
and all bargraph
LEDs will light along with
"88888"
for several
seconds. "
HALE
" will then appear for
several seconds while the system checks
itself followed by the default display (See
figure 3-1). If default display does not
appear, refer to TROUBLESHOOTING for
possible causes and solutions.
PRIMING FOAM PUMP
After the foam tank(s) are filled and the
system is powered up foam concentrate
flow must be checked to verify the foam
pump is primed.
CAUTION:
When operating the Hale
FoamMaster in Simulated Flow mode an
outlet for the foam concentrate must be
provided to prevent excessive pressure
buildup in discharge piping or hoses.
1. Make sure the bypass valve is in the
BYPASS
position. Route the bypass hose
into a suitable container to collect the
discharged foam concentrate.
2. If dual foam tank system is used select
TANK A
. Make sure there is foam
concentrate in both foam tanks.
3. Place the system in simulated flow mode
by selecting the
FLOW
display and
depressing
RESET
(both up
é
and
down
ê
buttons simultaneously).
Increase simulated flow value by
