J-PRO-22 Installation Instructions
While you can mount the pump on a shelf above the solution tank, it is strongly advised to
mount the pump directly on top of the solution tank. If the tubing from the foot valve to the
suction side of the pump exceeds 60”, the unit will not have enough lift force to stay primed.
Mount Pump to Solution tank
Place pump on tank. Mark where the anchor holes
will be drilled. Drill pilot holes with a small drill bit
so that the pump can be mounted on the tank with
two wood or sheet metal screws.
We recommend screwing them in after the pump
has been primed and the tubing has been hooked
up for easiest installation.
Mark the holes for the suction tube and the
degassing return line and drill holes.
How to Connect Tubing
& Fittings
Note: Warming tube ends with hot water or a
hair dryer helps with tubing installation.
• Trim the end of the tubing square (cut with a
new box cutter blade).
• Slide the connector nut onto the tube.
• Push the tubing over the conical tting until the
tubing is ush against the end of the tting.
• Screw the connector nut on, hand tight.
• Do not use Teon tape/ paste on the tubing
tting connections.
Use the harder/stier translucent tubing for connection from discharge-side (12 o’clock)
to the injection check valve.
Use the softer clear tubing for the foot valve to suction-side (6 o’clock) connection.

Install Discharge Side Tubing
This is the tubing that goes from the pump discharge
(outlet) to injection check valve in pipe tee.
1. Shut o well pump or water supply and de-pressurize
service pipe.
2. Install injection check valve by installing a pipe tee
in your pipe that has a ½” NPT tting, where you can
screw in the injection check valve (included with your
J-PRO-22 pump).
3. Wrap Teon tape on the ½” pipe threads of the
injection check valve and apply a light coating of white
Teon pipe paste and install into Tee tting.
4. Trim the end of the injection check valve tting so that
the end will be in the center of the service pipe.
5. Make sure to install injection check valve in to pipe
directly. If the end of the check valve is not in the
service pipe, it will not work. Do not install a ball valve,
or any length of pipe run, coming o the tee.
6. Using a hack saw or cutter, trim the end of the
injection check valve if needed, so it inserts into the
water pipe as shown.
7. Install tubing that came with your pump and connect
pump to injection check valve.
8. Cut tubing to desired length with enough slack to avoid kinks.
Injection check valve can be installed into PVC, copper or other piping.

Install Suction Tubing from Pump to Solution Tank
Connect hard tubing from foot valve in Solution Tank to Inlet/ Suction side of metering pump
1. Measure the tubing from the outside of the solution tank to ensure it will be 2-3” from the
bottom of the solution tank.
2. Do not allow weight to sit at the bottom of the tank. Connect tubing to the foot valve and put
the ceramic weight on.
3. Run the tubing up through the hole and connect to the Inlet/ Suction side of pump

1. Flow Meter Cable WHITE wire Connects to Pump Cable
RED wire (trim back, disregard other color wires)
2. Flow Meter Cable BLUE wire connects to Pump Cable
GRAY wire. (trim back, disregard other color wires)
3. Solder or connect the wires with wire nuts, or
electrical tape and then seal with shrink wrap or
electrical tape.
Prime & Start the Pump with
Water First
1. Add 4 gallons of distilled or puried or softened to solution tank.
2. Adjust the 2FV “kicker port” (which is the Degassing Valve) so it is open approximately ½ to 1
turn counter-clockwise.
3. Plug the pump in to electrical outlet.
4. Pump will be in Manual Mode, with the % at 100%
5. “Motor” light will be Green. “Auto” light will be o.
6. Press the ON-OFF button, pump will start pumping.
7. You will quickly see water being pumped up the suction tube and out the degassing tube.
8. After the pump is primed, close the degassing valve. The valve shall remained closed for
normal operation.
9. After the pump has been in operation for an hour or so, you should check the liquid end of
the pump (back end) and re-tighten the four stainless steel Allen-head screws on the head in
a crisscross fashion. Take care not to overtighten as you may damage the pump.

Program and Pump Settings
NOTE: When making programming changes to the pump, you must wait at least 15 seconds for
the updated changes to be stored in the memory. Making additional changes or shutting o
power to the pump prior to this waiting period will default back to the original settings.
When rst plugged in, pump display will read “100” and be in Manual (non-pulse) mode.
“MOTOR” light will be green.
1. Press and hold the SET button for several seconds until “AUTO” light turns green.
2. Now press and hold both the SET button and UP Arrow button for a moment and release.
3. Using UP Arrow button only, adjust to 6, which gives you six pump strokes for each gallon of
water owing through the ow meter. If you get into negative numbers, you must scroll the
down arrow key to zero in order to scroll up to positive numbers.
4. After you have selected the number of strokes per gallon, press and release the Set button to
conrm the setting.
5. Finally press the ON-OFF button once, and now your pump is in automatic mode.
Note: Check to see if pump is operating correctly by running the water and comparing pump
actuations vs. programmed strokes per gallon of water owing through the meter.
During Auto mode, numbers appearing on the readout have no meaning or direct correlation to
amount of solution being injected.
Later you can adjust it higher (or lower) depending on the desired chlorine residual. For more
information on that, see example calculations below.
How to Select the Citric Acid Solution Strength and
Pump Setting
• The goal of a properly functioning Citric Acid injection system is to reduce the pH of your
water to the 7 to 8 pH range.
How Much Citric Acid Should Be Injected?
For citric acid, a good starting point is 1 lb of citric acid (2 cups) dissolved in one gallon of soft or
pure water. Warm water dissolves more rapidly.
Pulses Per Gallon setting on pump: Set to 6 to start.
Test the pH, and then either turn up the pump if the pH is not low enough, or add another 1/2
gallon of water if it is too low.

Troubleshooting and Maintenance
Most problems occur with the connections, it can sometimes be hard to push the tubing onto
the cones, sometimes ttings are over-tightened, or people use Teon tape and paste on ttings
that do not need it.
Remember, above all, if the pump pumps in manual mode (makes a ka-thunk, ka-thunk sound),
then it works.
Is pH too Low? Too much Citric Acid?
Adjust the strokes per gallon down to 1 or 2, and/or make the Citric Acid solution more diluted
by adding more distilled water.
If you cannot get it to prime, it is either because a tting is too loose, too tight, or not
installed correctly.
If you see the water going up and down in the tubing, this indicates the foot valve is not tight, or
you installed the pump too high above the solution tank, or you mounted the pump improperly.
Sometimes, as mentioned earlier in the guide, it is because the four Allen head bolts on the
pump head have loosened, and need to be tightened, do not over-tighten.
If the solution has lled up the tubing, but it is not discharging, make sure the de-gas is opened,
and then close it until the point when it starts pumping.
The tubing going from the outlet/discharge to injection check valve will twitch
and move at the same time the pump triggers, that is how you can conrm you are
pumping solution.
If this does not work, remove the discharge-to-injection check valve tubing from the outlet
tting, and see if it strokes out of the top- if it does, this indicates that the problem is in the
injection check valve, or that you are trying to pump against greater than 100 psi.
Winterizing: do not let the J-PRO-22Pump or tubing freeze. If you need to winterize, drain the
Citric Acid solution tank and discard Citric Acid solution. Place the suction of the pump into a
bucket of clean water and allow the pump to run until the J-PRO-22Pump is free of any Citric Acid
solution. Remove the suction from the water and allow the pump to pump dry. Pump is ready to
store.
NOTE: when diluting the Citric Acid, use only distilled water, water from a reverse osmosis
system, or at least softened water. Do not use untreated well water.
