IMPORTANT:
 ALL PLUMBING IS TO BE INSTALLED IN ACCOR-
DANCE WITH APPLICABLE CODES AND REGULA-
TIONS.
 FLUSH ALLWATER 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
sensor 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
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.- 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
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.
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 Valve Installation
The supplied inlet filter must be used with every faucet,
unless a mixing valve is ordered. The inlet filter is attached
directly to the electronics modules water inlet. Tempered
water is then supplied to the filter using a standard 1/2 ball
riser (supplied by others.)
The optional mixing valve (-MV) with integral filter replaces
the standard inlet filter. The mixing valve outlet is attached to
the electronics module with a 3/8 compression to 1/2 ball
riser (supplied by others). Hot and cold water is then
supplied to the appropriate mixing valve 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 sensors detection zone (8 approx.), the
beam is reflected 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 reflected 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 special decora-
tive 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.
