STEP 7. BASIC OPERATION AFTER CALIBRATION
Proximity
®
sensing technology works by creating an electrical field around a conductor (the spout) and
monitoring the change in capacitance that the conductor undergoes. The change in capacitance (the
ability to store an electrical charge) is brought on by a 2nd conductor (a human body) entering the
Proximity
®
field. As the human hand enters and leaves the vicinity of the electrical field around the
pout, the solenoid is opened and closed accordingly. It is critical in the installation process that all
electrical and mechanical connections be as tight and rigid as possible, ensuring a smooth signal is
carried from the driver board to the spout, and back again.

STEP 4b. CALIBRATION
After power is applied to the driver board, it generates 5 quick beeps
3 times which prompts the installer to step away from the unit.
During the calibration process, the water will turn ON for several
seconds then proceed to shut off. An additional 5 beeps indicates
calibration is complete and the faucet is ready to use. The cover
should be secured at this time.
STEP 6. TEST FOR OPERATION
STEP 5. SERVICES
Open screwdriver stop(s). Flush line. Install aerator.

Installation should be in accordance with local plumbing and electrical codes.
FLUSH ALL PIPES THOROUGHLY BEFORE INSTALLATION.
INSTALLATION AND SET UP INSTRUCTIONS
After calibration, test the function
of the product by placing your
hands within close proximity of
the spout (ensuring hands are
moving as if washing hands).
The solenoid will stay open
while hands are moving, then
close once hands are removed
from the sensing zone.

Test for operation. If OK, then close lid - Use caution not to damage
wires or components on electronic driver board. Route wires
through notches/openings in the box. See Fig 28. Secure lid
using screws.
If faucet leaks from spout outlet:
SHUT OFF WATER SUPPLIES. Check proper solenoid connection. Replace solenoid if problem persists.
If faucet exhibits very low flow:
A) Remove and clean Spray Outlet, or
B) SHUT OFF WATER SUPPLY. Clean or replace Screen Assembly.
If unit does not work properly, see Trouble Shooting Guide on pages 16 & 17.
