Calibrate Chemical Dosage
1.
Begin the process by setting the timing valve (22) to
an estimated setting of the flow rate. See
cycles per minute (CPM), and corresponding gal-
lons per day (GPD) and liters per day (LPD).
2.
Follow the instructions provided with your calibration
gauge in conjunction with the
3.
Adjust the timing valve (22) accordingly after the
test is performed. Turning the knob (122)
counter-clockwise will increase the pump flow rate,
while turning the knob clockwise will decrease the
flow.
4.
Repeat the test procedure to verify your changes.
Repeat as necessary until the desired flow rate is
achieved.
Stroke Adjustment
This pump has infinite stroke adjustment between full
and 1/4 stroke, and has four marked stroke adjustment
positions.
•
To increase the stroke length, turn the stroke adjust-
ment knob (21) counter-clockwise.
•
To decrease the stroke length, turn the stroke
adjustment knob (21) clockwise.
