Tools and Materials

Shut off the main water supply.
Carefully inspect the waste and supply tubing for any sign of
damage.
For new installations, install the faucet and drain to the lavatory

Faucet body should be installed no more than 1-1/8″(2.9 cm)
from the lip of the lavatory rim for the sensor to work. The faucet
body thickness is 2-1/4″(5.7 cm) or 2-3/8″(6 cm) with base.
If not using the optional thermostatic mixing valve, note that the
faucet has a single 1/2″NPSM inlet for cold or tempered water.
Four alkaline D-size batteries are included.
NOTE: In areas where the water has a high particulate level, install
a 20-micron water filter in the water supply line.

From the underside of the lavatory, run the plastic spacer (with
the flat surface towards the lavatory) up the faucet lead wire and
onto the spout shank. Fit the faucet lead wire into one of the
three spacer notches.
NOTE: Do not run the faucet lead wire through the center of the
washer and the locknut.

8. Troubleshooting
The faucet works properly if the following conditions occur during
the first 10 minutes after power up:
NOTE: To see the sensors you must remove the cover of the control
box.
The GREEN LED is on constantly and the faucet is running when
the faucet sensor sees an object.
If the faucet senses an object for more than 30 seconds, the faucet
stops flushing and the GREEN LED flashes until the object has
been removed.
If the faucet does not turn on:
Check the batteries for a charge and proper installation. Replace if
necessary.
Make sure the battery pack lead wires and the faucet are plugged
into the circuit board.
Check that the supply lines are open.
