Number before sending us back the pump for repair or replacement under the warranty. No returns can
be accepted without an RGA number.
The Warranty covers repair and/or replacement of the metering pump but not shipping costs.
While defects are rare, we do our best to respond to warranty returns fast as we can. Please allow 3 to 5
business days after pump has been returned for your pump to be repaired or a new one supplied under
the warranty agreement.
If the water supply and its continuous chlorination are critical, a back-up pump should be on hand.
Shipping charges are not covered under warranty. A flat fee of $9.95 each way will be charged for
ground shipping (continental US). Any expedited shipping (overnight, 2-day, etc.) is the customer’s
responsibility.
Conditions Not Covered by the Warranty:
Power surges or outages that cause pump failure are not covered under warranty.
Surge protection is strongly recommended. If a pump is returned for warranty replacement and the
cause of failure is determined to be from a voltage spike, the pump does not qualify for replacement.
This is the leading cause of failure. Pump failure during, or because of, power failure is not covered
under warranty.

Typical Installation (Diagram)

Rev 091718
How Your Chlorine Pump Works
The pump is designed to pull chlorine solution out of a solution
tank and pump a precise amount of chlorine into a pipeline under
pressure.
Right out of the box, this is a dual-voltage (110/220) pump.
There are several ways to wire the pump such that it triggers
when there is water flow.
The well pump is controlled by your pressure switch. Choosing
one of the ways outlined below, the chlorinator will be installed
so that it powers up and injects chlorine when the well pump and
motor are turned on via the pressure switch.
1. You can install a flow switch, and plug the J-Pro22 into that.
2. You can install it on a 110 volt or 220V pressure switch, using a dedicated electrical wall outlet.
3. If you have 220v, you can purchase an adapter that converts the 110- style plug into a 220
outlet, and wire a dedicated 220 outlet to the pressure switch, OR:
4. You can cut off the plug (this Does Not void the Warranty and is what we recommend if you are
using it for 220V) and wire it directly to your 220V pressure switch. This last method should only
be done by a qualified technician.

Rev 091718
Wire To Pressure Switch Option
How To Wire to Your Well’s Pressure Switch
Install a dedicated wall outlet that is wired in to the
pressure switch and powered up whenever the well
pump turns on.
The J-Pro-22 is a dual voltage pump. It has a 110 volt-
style plug.
A person who is qualified may (without voiding the
warranty) cut off the plug, and wire it directly to the
pressure switch terminals.
Avoid installing a dedicated wall outlet that looks like it is 110, but is actually 220.
You may cut off the 110 style plug and wire a 220-style plug, and then plug that into a dedicated 220-
style wall outlet.
Do not wire to Pump Capacitor Start Wire.
Use a Flow Switch Option
As an option to turn on and off the peroxide pump, install a flow switch. No electrical wiring to do and
any plumber, or person familiar with basic plumbing, can install it.
Simply plumb the pre-wired flow switch into your service pipe. Plug the flow switch into a standard 120V
wall outlet. Then, plug the chlorinator pump into the electrical outlet on the flow switch. Whenever
there is flow, the metering pump will then turn on.

Rev 091718
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
•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
fitting until the tubing is flush against
the end of the fitting.
•Screw the connector nut on, hand
tight.
•Do not use Teflon tape/ paste on the
tubing fitting connections.
Use the harder/stiffer 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.

Rev 091718
Install Discharge Side Tubing
This is the tubing that goes from the pump
discharge (outlet) to injection check valve in
pipe tee.
1. Shut off 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 fitting, where you can
screw in the injection check valve
(included with your J-PRO-22 pump).
3. Wrap Teflon tape on the ½” pipe threads
of the injection check valve and apply a
light coating of white Teflon pipe paste
and install into Tee fitting.
4. Trim the end of the injection check valve
fitting so that the end (where the
chlorine squirts out) 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
off 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.

Rev 091718
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

Rev 091718
Connect Tubing from Degassing Port (“Kicker Port”)
You can use the soft tubing for this run, connect tubing to the degassing port fitting (labeled on the
pump as “Kicker Port”) and pass tubing through the hole you drilled down into the tank 4-6”.

Rev 091718
Prime & Start the Pump
1. Fill solution tank with 4 gallons of soft, distilled, or RO water, but don’t add chlorine yet.
2. Connect the suction tubing to the foot valve and discharge tubing to your injection check valve.
3. Connect the degassing prime valve tubing and route to the solution tank, above the water line.
4. Open the degassing prime valve two turns counter-clock-wise to open it up. This will allow the
solution to be pumped back into the tank for fast priming.
5. Turn on the pump and set Speed to 100% if not already displaying 100.
6. You will quickly see water being pumped out the degassing valve return line port.
7. Close the degassing port valve until liquid starts pumping out the discharge side.
8. Allow to run for 10-15 minutes. Check for leaks.
9. After your chlorinator pump has been running for a few days, tighten 4 stainless steel bolts on
the pump end.
10. Don’t over-tighten, but it is recommended to re-tighten (once) and make sure these bolts are
tight after pump has been running.
Program Pump and Adjust Speed Settings
Out of the box, when you plug the unit in, the green Motor light is
indicating the pump has power. It will be set at 100 and start
pumping.
Press the Start/Stop button to stop the unit from pumping. The Up
and Down arrows are to adjust the Speed of the pump, from 0-100.
NOTE: Pump must be allowed to run for 15 seconds at the speed
setting, after you change the speed. For example: say you change
the speed to 70. Let run for at least 15 seconds before unplugging
pump. The pump needs 15 seconds to SAVE the new setting.
The Set button and the Auto light indicator have no function on this
model, they are for use with a flow meter.

About Chlorination
Chlorine is used for three main objectives:
1. Disinfection and inactivation of pathogens in water such as E. Coli.
2. Odor control: eliminates rotten-egg, metallic and other odors in water.
3. Oxidization of iron and manganese.
When chlorine is added to water, the water has a “demand” for chlorine. When that demand is
satisfied, any additional amount of chlorine added is called the “free residual”. As long as you have a
free residual of 0.2 ppm or higher, that water has enough chlorine, no more needs to be added.
To treat for coliform bacteria, the water must have a minimum amount of contact time typically ten
minutes or more with the chlorine, and a free residual detected. For odor, iron and manganese, only a
couple of minutes are needed.
It is better to use 12% strength Sodium Hypochlorite (Liquid Pool Chlorine) than to use 5% bleach like
Clorox, although the Clorox may be used. Avoid any scented bleaches.
Add the Chlorine: How Much Chlorine to Add to Water
1. Once the pump is primed and pumping with water, add ½ gallon of 10% to 12% Liquid Pool
Chlorine (pure sodium hypochlorite) to the solution tank, and fill with purified or softened water
to the five-gallon mark (you started out with 4 gallons from the instructions previous).
2. Set the pump speed at 50. If your well pump pumps between 5 and 15 gallons per minute, this
will give you an applied chlorine dosage of 2 to 10 PPM. See below for more info and formula.
3. If you have a contact tank after the chlorinator, start drawing water through the system,
injecting chlorine.
4. Start testing for a free residual after the contact tank.
5. The color spectrum for the chlorine free residual test kit that comes with your system goes from
a pale yellow (0.2 – 0.5 PPM) to a bright yellow (1.5 – 3.0 PPM) and then orange and red, too
much residual chlorine, above 4.0 ppm.

Rev 091718
6. If you get too much chlorine you can turn down the speed of the pump or make the chlorine
solution more diluted.
7. Once you are in the yellow spectrum, use the up and down arrows to adjust the speed setting,
until you are measuring 0.2- 1.0 ppm residual. Usually, values 0.5 and below are too low to
smell the chlorine, that is often ideal depending on the application.
Formula for Calculating Solution Strength and Settings
Note: mg/L is the same as Parts Per Million. 12% chlorine is the same as saying 120,000 PPM of
chlorine. 5% household bleach is 50,000 PPM chlorine.
If you added 1 gallon of 12% chlorine to 9 gallons of water (or ½ gallon of bleach to 4-1/2 gallons of
water), you would end up with approximately 12,000 PPM solution strength.
How many parts per million of chlorine should I inject?
Apply 1.0 PPM of chlorine for every 1 PPM of iron; 2 PPM of chlorine for every 1 PPM of Hydrogen
Sulfide and/or Manganese.
The simple formula is: Flow Rate in Gallons Per Minute GPM x Parts Per Million of Applied Dosage x
1440 Minutes in One Day = Gallons Per 24 Hour Period of Chlorine.
Example: Assume you wanted to apply 5.0 PPM of chlorine to your well water. You diluted ½ gallon of
12% chlorine with 4.5 gallons of water, which is approximately a 12,000 PPM chlorine solution strength.
You know your well pump flow rate is 12 GPM.
5.0 PPM x 12 GPM x 1440 Divided by 12000 = 7.2 Gallons Per Day
What this mean is approximately 7.2 gallons of the chlorine solution will be pumped for every 24 hours
your well pump runs. Your well pump does not run 24 hours each day usually.
For example, If your well runs 2 hours a day, in 12 days you would use about 7.2 gallons of the diluted
chlorine solution.
Therefore, you need a chlorinator pump that can pump 7.2 gallons in 24 hours. The JPRO-22 pump
pumps 22 gallons per 24 hours. So: 7.2 divided by 22 = 32%
Set the JPRO-22 speed to 32%, which will turn it into a 7.2 Gallon Per Day Pump.
Troubleshooting and Maintenance:
Most problems occur with the connections, it can sometimes be hard to push the tubing onto
the cones, sometimes fittings are over-tightened, or people use Teflon tape and paste on
fittings that do not need it.

Rev 091718
If the pump pumps in manual mode and makes a thumping sound, then it is working.

Priming Problems
1. If you cannot get it to prime, it is either because a fitting is too loose, too tight, or not
installed correctly.
2. While the pump is running (usually, on Manual), observe if the fluid is coming up the
tube- 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.
3. Sometimes, as mentioned earlier in the guide, it is because the four Allen head bolts on
the grey pump head have loosened, and need to be tightened, do not over-tighten.
4. If the solution has filled 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.
5. 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 confirm you are
pumping solution.
6. If this does not work, remove the discharge-to-injection check valve tubing from the
outlet fitting, and see if it squirts 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.
Maintenance Tips:Check free-chlorine residual at least once per month and adjust the J-PRO-
22Pump and/or solution strength if needed.
Winterizing: do not let the J-PRO-22Pump or tubing freeze. If you need to winterize, drain the
chlorine solution tank and discard chlorine 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 chlorine solution.
Remove the suction from the water and allow the pump to pump dry. Pump is ready to store.

Rev 091718
NOTE: when diluting the bleach, use only distilled water, water from a reverse osmosis system,
or at least softened water. Do not use untreated well water.
