If using a dual tank system, each concentrate
can be separately defaulted to the concentrate
injection rate individually, by selecting either
tank "A "or "B" on the electric selector switch or
the manual valve. The display will show PAx.x
(Tank A) or Pbx.x (Tank B) depending which
tank is selected. Set the desired injection rate
using the or buttons. Using the electric
selector switch or the manual valve switch to the
other tank and set the desired injection rate for
that concentrate.
Exit the Calibration and Setup mode as
previously described.
FOAM PUMP CALIBRATION
Note: The viscosity of different foam
concentrates may have an effect on the amount
of foam concentrate that is injected into the
water stream. When calibrating the foam pump,
use the foam concentrate that will be used most
frequently during normal operations. When
different viscosity foam concentrates are used,
the actual concentrate injection may vary by as
much as 10%. When using the dual tank
system, each foam concentrate should always
be calibrated individually. Select tank "A" or "B"
on the electric selector switch or the manual valve.
Enter the Calibration and Setup Mode using the
method previously described. Press the SELECT
button to illuminate the light below TOTAL
FOAM on the Digital Display Control Module.
Turn the “CAL/INJECT” valve pointer to the Cal/
Flush position. Place a graduated measure
container beneath the outlet from the
CAL/INJECT valve that can contain the
expected volume of foam concentrate (minimum
5 gallons [19 liters]). If an accurate calibrated
container is not available, a scale can be used
to weigh the foam concentrate pumped. The
total volume of foam concentrate can then be
calculated from this weight.
Start the FoamPro foam pump by pressing the
red “FOAM” button. The foam pump will
operate and pump foam concentrate into the
container. Stop the foam pump and measure
precisely the amount of foam concentrate collected.
Adjust the reading on the Digital Display Control
Module to the volume pumped by pressing the
or button. Repeat the procedure two to
three times to verify calibration.
If using a dual tank system, switch to the other
tank by using the electric selector switch or the
manual valve. Repeat the calibrating procedure
using the method previously described.
Turn the CAL/INJECT valve back to “INJECT”
position.
Exit Calibration and Setup mode as previously
described. REPLACE THE COVER SCREW.
The system is now calibrated to the actual flow
from the foam pump.
These Setup and Calibration procedures
complete the adjustment of the system. The
FoamPro system is now ready to be placed in
service.
If this system is installed and calibrated by an
apparatus manufacturer or dealer, the end user
may wish to adjust the default Foam
Concentrate Injection Rate and/or Simulated
Flow to their special needs. These changes
can be made without altering the calibration by
using the procedures for those functions only.
