INSTALLATION INSTRUCTIONS
USAGE INSTRUCTIONS
1. Remove the contents from the box.
2. Insert the controller into the panel. A square hole must be cut into the panel with dimensions
of 2-11/16 in. x 2-11/16 in. (68 mm x 68 mm). Page 8 includes a cut-out diagram.
3. Mount the controller to the panel by inserting the mounting brackets into the grooves on the
bottom and top of the controller. Fasten the brackets with the included screws.
4. View the contact diagram on the side of the controller (also on page 8).
5. Do NOT connect to a power source yet! Connect the black power cord to the contacts
#8 & #9 (110 V - 230V). It does not matter which color wire is connected to the
contacts. Screw in tight with a Phillips head screwdriver. (Note – If in the U.S. (or a country
that uses Type A or B plugs/sockets), connect the included plug adapter to the power cord).
6. If using a pump, valve, etc., connect a relay wire (not included) to contacts #13 and #14 for a
normally open (N.O.) position OR to contacts #12 and #13 for a normally closed (N.C.) position.
7. Connect a gray sensor cable by attaching the white wire to contact #1, the red to #2, and the
black to #3.
8. Connect the second sensor cable by attaching the white wire to contact #5, the red to #6, and
the black to #7. The cables are identical and can be swapped.
9. Align the pins of each sensor to each cable and attach. Screw the tightening ring closed. The
sensors are identical and can be swapped. Note which sensor is now the IN sensor and which is
the OUT sensor.
10. Insert each sensor electrode into a female ½” NPTF threaded tting.
11. Attach the tting connected to the OUT sensor to the product water.
12. Attach the tting connected to the IN sensor to the feed water.
13. Ensure the orientation of the sensor is perpendicular to the ow of the water. Water
should ow equally over both pins. (If using a T, if you look through the top of the T, you
should see both pins equally side-by-side. If using the sensor in a tank, ensure that there are
no air bubbles trapped between the pins or in a tting.)
14. To DISCONNECT the audible alarm, disconnect the blue wire from contacts #10 and #11.
15. Plug the power cord into an electrical outlet. The controller does not have a power switch
and will automatically power on when the power is connected.
