IMPORTANT:
• ALL PLUMBING IS TO BE INSTALLED IN ACCORDANCE
WITH APPLICABLE CODES AND REGULATIONS.
• FLUSH ALL WATER LINES PRIOR TO INSTALLATION.
• SENSOR UNITS SHOULD NOT BE LOCATED ACROSS
FROM EACH OTHER OR IN CLOSE PROXIMITY TO HIGHLY
REFLECTIVE SURFACES.
1. - Cover Plate Installation
(For faucets with -CP4 or -CP8 suffix)
Remove adhesive backing from gasket and then pass sen-
sor connector wire and shank through gasket. Align gasket
with faucet bottom and press firmly together. Pass sensor
connector and shank through cover plate and fasten to the
faucet with the provided screws.
3.- Electronics Module Installation
Attach sensor connector wire from the faucet to the mating
sensor connector wire from the eletronics module. Orient con-
nectors so that the pins are properly aligned before pressing
connectors together. Do not force together, damage to pins
may occur. Secure the cable connectors with the locking ring
provided. Be certain that the cable connection is made be-
fore the batteries are installed.
Attach electronics module to the shank using the hex nut and
gasket provided. Orient the electronics in a convenient loca-
tion and tighten hex nut.
DO NOT USE THREAD SEALANT.
2.- Base and Spout Installation
If there is an exsisting faucet, turn off water supply and remove
the old faucet. Assure supply lines are completely flushed and
free of debris. Clean lavatory rim around the mounting area for
the new sensor faucet.
Place the sensor connector wire and shank through cover
plate gasket and hole in the lavatory. Orient black plastic mount-
ing washer with the slot facing up. Place mounting washer
and star washer over shank and secure the entire assembly
to the lavatory with the mounting nut. The sensor wires must
pass through slot in plastic mounting washer.
*Do not pinch Sensor wires.
Insert white rigid washer provided into top orifice of base.
Install spout and secure with spout nut.
*Do not over tighten.
4a.- Battery Installation
Loosen the battery cover screw with the supplied allen wrench.
Remove the cover and install the batteries as indicated on the
battery case. Replace the battery cover and secure.
4b.- ACA Plug-In Adapter Installation
When using the -ACA plug-in power supply remove sticker at
location (A) and plug in adapter.
5.- Filter or Mixing Tee or Mixing Valve
Installation
The supplied inlet filter must be used with every faucet, un-
less a mixing tee or mixing valve is ordered. The inlet filter is
attached directly to the electronics module’s water inlet. Tem-
pered water is then supplied to the filter using a standard 3/8”
x 1/2” ball riser (supplied by others.)
The optional mixing tee assembly (-MT) or mixing valve (-MV)
have integral filters and back checks. These take the place of
the standard inlet filter when ordered. The mixing tee or mix-
ing valve outlet attaches to the electronics module with a 3/8”
x 1/2” ball riser (supplied by others). Hot and cold water is then
supplied to the appropriate 3/8” compression inlets.

OPERATION
1.) Invisible light rays are continually emitted from the fau-
cet sensor.
2.) When the user’s hands come into range of the sensor’s
detection zone (8” approx.), the beam is reflected back to
the sensor’s reciever and converted to a low voltage elec-
trical signal activating a solenoid valve.
3.) After the user removes their hands, the absense of re-
flected light stops the low voltage electrical signal, closing
the valve. The circuit automatically resets for the next user.
4.) If an object is in view continuously for thirty seconds,
the faucet will automatically shut off. The faucet will re-
main off until the object is removed. After the object is
removed, the faucet functions normally.
CARE AND CLEANING INSTRUCTIONS
DO NOT use abrasive or chemical cleaners to clean faucets as they will dull the luster and attack the chrome or special
decorative finishes. Use only mild soap and water, then wipe dry with a clean cloth or towel. While cleaning the bathroom
tile and floor, the faucet and electronics should be protected from splattering of water, cleaner, acids and cleaning fluids
that can damage the sensor faucet.

engaged.
Check cable connection. Remove battery, and disengage the
cable connection. Check cable
connection for broken pins and
reconnect cable.Check battery for
volta
g
e level and reinstall.
Low battery. Flashing red light in
sensor eye indicates low
battery.

inoperative
Move hand in front of
faucet to see if solenoid
valve is clicking. See
note in Step 4.
Remove the batter y and shor t c ir cuit
the batt er y term inals with allen
wrench. This will reset the
electronics. Replace battery.
