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 HIGH-
LY REFLECTIVE SURFACES.
1. - Cover Plate Installation
(For faucets with -CP4 or -CP8 sufx)
Remove adhesive backing from gasket and then pass sensor
connector wire and shank through gasket. Align gasket with
faucet bottom and press rmly 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 sen-
sor connector wire from the eletronics module. Orient connectors
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 before the
batteries are installed.
Attach electronics module to the shank using the hex nut and
gasket provided. Orient the electronics in a convenient location
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 ushed 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 mounting
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 orice 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 lter must be used with every faucet, unless a
mixing tee or mixing valve is ordered. The inlet lter is attached
directly to the electronics module’s water inlet. Tempered water
is then supplied to the lter 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 lters and back checks. These take the place of
the standard inlet lter when ordered. The mixing tee or mixing
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
faucet sensor.
2.) When the user’s hands come into range of the sen-
sor’s detection zone (8” approx.), the beam is reected
back to the sensor’s reciever and converted to a low
voltage electrical signal activating a solenoid valve.
3.) After the user removes their hands, the absense of re-
ected 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 remain
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 spe-
cial decorative nishes. Use only mild soap and water, then wipe dry with a clean cloth or towel. While cleaning the
bathroom tile and oor, the faucet and electronics should be protected from splattering of water, cleaner, acids and
cleaning uids that can damage the sensor faucet.

fully engaged.
Check cable connection. Remove battery, and disengage
the cable connection. Check cable
connection for broken pins and
reconnect cable.Check battery for
voltage level and reinstall.
Low battery. Flashing red light in
sensor eye indicates low
battery.
Remove batteries and replace with
4 new alkaline batteries.
Solenoid valve inoperative. Move hand in front of
faucet to see if solenoid
valve is clicking.
If clicking, open solenoid valve and
clean it.
If not clicking, replace solenoid
valve.
Sensor/electronics are
inoperative
Move hand in front of
faucet to see if solenoid
valve is clicking. See
note in Step 4.
Remove the battery and short
circuit the battery terminals with
allen wrench. This will reset the
electronics. Replace battery.
Filter is plugged. Shut off water supply.
Remove clean out cap.
Clean the lter and reassemble.
Faucet continues to
run for more than 30
seconds or drips
Solenoid valve is dirty. Open the solenoid valve
and check for debris.
Carefully observe the
way valve goes together
for reassembly.
Shut off water supply. Disassemble
solenoid and remove debris from
diaphragm and/or plunger tip.
Reassemble solenoid.
