Installation
1. Remove the battery insulation tab.
2. Insert the sensor fully into the union tee and make sure the sensor
pins are perpendicular to the direction of the union tee as shown in
the diagram. Both pins should be seen when looking through the
union tee so the water will flow over both pins equally.
3. Turn off the RO/DI systems. Cut the tube at the desired monitoring
point and connect the cut tubes to the union tee.
