Operation and Installation Instructions for Electronic Faucets-Battery-Powered

The battery-powered faucet is designed for ease of installation and provides a reliable, convenient, economical and sanitary system for high-volume users, such as hospitals, transportation terminals, restaurants, schools, sports arenas, office buildings and municipalities. It can be installed by one tradesman without electrical hook-up.

Operation:

1.The faucet operates by emitting a continuous infrared beam from the sensor.

2.As the user enters the beam’s effective range, a red light flashes one time to alert the user that the faucet will operate. As long as the user is in the beam’s range, the beam is reflected into the receiver circuitry and the system will operate.

3.When the user exits out of range, the sensor sends a signal to the solenoid for closure. The sensor then automatically resets and is ready for the next user.

4.Low battery indicator light comes on when battery is low.

Caution: Avoid installing the faucet where sensor faces a stainless steel wall or other reflective surface within the active range of sensors. Avoid facing another infrared sensor. It may cause faucet to activate unnecessarily.

INSTALLATION INSTRUCTIONS

DRY TEST

ATTENTION: To insure proper operation, before installing the faucet, a “DRY TEST” is recommended.

1.Take off the control box lid (17) by removing screws (16) with hex wrench.

2.Connect the sensor eye connector (25) at the end of the sensor eye cable (22) onto the circuit board (30) inside the control box (19) Refer to illustration “A”.

3.Slide battery housing out of control box (19) and install batteries (included) and slide battery housing back into control box (19). Insert the battery housing connector onto the circuit board. The lights on the circuit board should blink red/green/red.

4.Place your hand in front of the sensor (28) to operate the faucet and listen for a “clicking” sound.

5. Remove your hand and listen for a softer “clicking” sound. The “clicking” sounds

indicate that the faucet is working properly. If there is no light or sound, please contact Moen at 1-800-289-6636.

6.The sensors are equipped with angular adjustments. The factory setting is in the center or straight position from the faucet. Adjustment is most easily performed before the faucet is installed. The adjustment is located inside the faucet body (1) behind the LED indicator liight (31) Refer to illustration “B”.

7.If you are ready to install the faucet, disconnect the sensor eye connector (25) at the end of the sensor eye cable (22) from the circuit board (30).

8.Ensure that the o-ring gasket (7) is seated properly and in place in the groove of the faucet body.

9. Set faucet on sink and install slotted washer

(9) and mounting nut (10). Tighten mounting nut (10) to secure the faucet to the sink.

10.Attach 90 degree elbow (11) to the mounting bolt (8). Tighten elbow (11) to secure to the mounting bolt (8).

11.Attach compression reducer (32) to the 90 degree elbow (11). Also attach compression adapter (13) to the solenoid valve outlet.

12.Connect the sensor eye connector (25) at the end of the sensor eye cable (22) onto the circuit board (30). Properly seat both the sensor eye cable seal and cable into the control box slot on the left. Reinstall control box lid (17) and tighten screws (16) to insure the control box is water-resistant. NOTE: make sure that the rubber seal plug is in installed in the AC adapter control box slot (on the right).

13. Connect 3/8” copper tube (supplied) between the 90 degree elbow (11) and the solenoid valve (23). Tighten compression fittings.

14.Insert white nylon washer (15) into swivel nut on filter body inlet.

15.A) For standard (pre-tempered or cold water) installation, attach water supply to inlet of in-line filter/check valve body.

B)If a tempered water installation is needed, attach mixing/check valve (optional) to the inlet of in-line filter/check valve body. Connect water supply lines to mixing/check valve. Refer to illustration

“C”. NOTE: USE TEFLON TAPE FOR ALL THREADED CONNECTIONS.

C)Refer to Illustration D for the optional mixing tee installation.

16.Mount faucet spout (3) to faucet body (1) and secure with spout o-ring (6) and spout nut (5). Tighten spout nut (5).

17. Turn on water and check for leaks. Place hand in front of sensor to activate water. Remove hands and the water should stop. If not, refer to troubleshooting guide.

18. For timing adjustments, refer to instructions on the inside of the control box lid. Refer to Illustration E.

A)Note: Be sure to depress the re-set button, located on the circuit board, after each adjustment.

B)The factory settings are:

Sensor Distance Adjustment = approximately 3.5 inches from the lens

Time Delay to shut-off after hands are removed = 1 sec seconds

Auto – shutoff = 30 seconds
