INSTRUCTIONS FOR SETTING THE SENSOR RANGE:
The EC-3122 uses a digital infrared, distance adjustable sensor which has a default
range set at the factory. Should this range need to be changed, follow the steps
below. The sensing distance is adjustable from 3/4” (2cm) to 6 11/16” (17cm).
1. Shut off the water at the hot and cold supply stops.
2. Place the magnet provided to the upper right side of the sensor lens and move it
closer to the lens.
3. Hold the magnet in place for 3 to 5 seconds. The red sensor LED will come on for
set-up mode.
4. Remove the magnet and the sensor LED will go out.
5. Place a hand to the desired sensor range, hold in place and the LED will light up.
(The recommended sensor range is 3/8” [1 cm] in front of the spout)
6. Place the magnet to the right side of the sensor lens and move it closer to the lens
until it starts blinking 5 times.
