DEMA Ag 0960.A
Slide2Installation
The
Flexflow Pump is prewired for easy installation. Select a secure horizontal surface that is convenient to the electrical and plumbing connections that is accessible by the operator. Do not install pump in a location where the ambient temperature exceeds 120°F (50°C).The pump is suitable for most outdoor installations, shielding from direct exposure to the elements is recommended. The properties of the solutions to be metered should also be considered concerning temperature changes and effects to the poly tubing

Priming – Plug in pump and set stroke knob to 100%
(To avoid damage to the pump, this adjustment should only bemade while pump is running at a high stroking rate.)If fluid begins moving up suction line while pump is operating
No further priming is required.
If fluid is not moving, open bleed valve approximately 1 turn
Until fluid begins to move. When suction line fills, close bleed
valve.
Do not over tighten bleed valve. Damage my

Control Mode Options
OFF
– The
OFF
control mode will stroke the pump at a user defined rate.
From 0-125 strokes per minute or per hour.
Click here for programming
pH Control
– The
pH control
mode will allow the pump to stroke proportionately
b
ased on high and low pH set points. This will allow the pump to stroke faster
as the pH reading moves away from the desired control level and slower as it
gets closer to it
.

programming
pH/Flow
– The
pH/Flow control
mode uses a multiply/divide feature as a part of
the programming that allows for an incoming dry contact pulse (such as from a
water meter) to dictate how many times the pump will actually stroke.
For example, setting the “Multiply” to 5 means that a single incoming pulse
f
rom the water meter indicates to the pump that it needs to multiply that
b
y 5, which would cause the pump to stroke 5 times per dry contact pulse that it
receives.
If the pump is was set in “Divide” that signal by 5, then it would require receiving 5
d
ry contact pulses from the water meter before the pump would stroke once.

All Flex Flow pumps are factory calibrated. The reading should be verified for accuracy
and adjusted as per the instruction.One Point Calibration – Units can be one point calibrated by leaving the cleaned probe,on-line sensing in a known pH or ORP fluid* then entering that value in the calibration
screen.
See instruction manual for more calibration options.
Warning:
Do not allow probe to become dry! Damage will occur and a new probe may
be needed.
Probes typically last 6-18 months depending on installation and care

** - Multiply function takes a single pulse from the water meter and allows you to multiply the
Strokes. If you multiply by 5 then the pump will stroke 5 times per pulse from water meter.
Divide function takes a single pulse from the water meter and allows you to divide the strokes.
If you divide by 5 then it will take 5 pulses from the water meter before the pump comes on.
Maintenance
Cleaning the pH Probe
Disconnect probe leads from the pump
Remove probe from pipe
Inspect the end of the probe for build up and contaminates
Use a spray cleaner (409) on the end of the probe.
Let is soak
DO NOT WIPE THE END OFF THE END OF THE PROBE!
This can damage the membrane of the probe!
Recalibrate
Re-install into the system.
A well maintained pH probe should last 12-16 months.
