Moen 8301 Manuel D’Utilisation

ATTENTION: To insure proper operation, before
installing the faucet, a “DRY

TEST” is

recommended.

1. Take off the control box lid (13) by removing

screws (12) with hex wrench. 

2. Connect the sensor eye connector (20) at the

end of the sensor eye cable (18) onto the
circuit board (24) inside the control box (10)
Refer to illustration “A”.

3. Slide battery housing out of control box (10)

and install batteries (included) and slide
battery housing back into control box (10).
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 (23) 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 light (25) Refer to illustration
“B”.

7. If you are ready to install the faucet,

disconnect the sensor eye connector (20) at
the end of the sensor eye cable (18) from the
circuit board (24).

8. Attach supply rod (6) into threads located at

the bottom of the faucet body (1). If needed,
snug the supply rod (6) with a “8 mm” hex
wrench. Attach compression reducer (28) to
the supply rod (6). Also attach compression
adapter (7) to the solenoid valve outlet. 

9. Attach the mounting bolts (2) to the faucet

body. If needed, snug mounting bolts (2) with
Phillips screwdriver. 

10. Slide gasket (3)  over sensor eye cable and

onto faucet. 

11. Set faucet on sink and install slotted washers

(4) and mounting nuts (5). Tighten mounting
nuts (5) to secure the faucet to the sink. 

12. Connect the sensor eye connector (20) at the

end of the sensor eye cable (18) onto the
circuit board (24). Properly seat both the
sensor eye cable seal and cable into the
control box slot on the left. Reinstall control
box lid (13) and tighten screws (12) 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 supply rod (6) and the solenoid valve
(17). Tighten compression fittings.

14. Insert white nylon washer (9) 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. 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.

17. 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

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.

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.

:  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.
