Prime the Pump
1.
Remove power to the pumpjack and wait for the
pumpjack to stop moving.
2.
Disconnect lever arm (122) from the pumpjack.
3.
Verify all connections and fluid lines are tight.
4.
Verify only the inlet valve (215) is open.
5.
Place a chemical compatible bucket under the bleed
valve (210).
6.
In order to prime the pump, turn the bleed needle
(211) counterclockwise.
7.
Operate the lever arm (122) by hand to prime the
pump.
8.
The pump is primed when discharge from the bleed
valve (210) has transitioned from air, to bubbly liquid
chemical, to pure liquid chemical.
9.
Turn the bleed needle (211) clockwise until tight and
verify that fluid has stopped draining from the port.
10. Reconnect the lever arm (122) to the pumpjack.
Refer to
Pumpjack Connections
, page 10.
Calibrate Chemical Dosage
1.
With the pumpjack turned off, set the stroke adjust-
ment of the pump to an estimated setting for the
desired flow rate. Refer to
Adjust the Pump
Stroke
, page 14, and
Baseline Chemical Dosage
Settings
, page 16.
2.
Follow the instructions provided with your calibration
gauge.
3.
Adjust the stroke adjustment accordingly after the
test is performed. Increasing the stroke adjustment
of the pump will increase the pump flow rate.
4.
If a slower flow is desired, slow the pumping rate of
the pumpjack, or adjust the orientation of the lever
arm by removing the retaining clip (123) at the base
of the lever arm (122) and rotating the handle to a
different position on the octagonal shaft. This will
lengthen or shorten the lever arm stroke.
5.
Repeat the instructions provided with your calibra-
tion gauge to verify changes.
6.
Repeat steps 3 - 5, as necessary, until the desired
flow rate is achieved.
NOTICE
To avoid potential damage to equipment, verify that all
system valves are open before priming the pump.
