STEP 6. 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 spout, 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 5. TEST FOR OPERATION
620TPxxx1TR Hard Wire Operated Control Box #1 Trim
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 Aerator, or
B) SHUT OFF WATER SUPPLY. Clean or replace Screen Assembly.

STEP 4a. CONNECT ELECTRICAL SUPPLY,
SOLENOID VALVE AND SENSOR
(cont’d)
Turn on power supply for the transformer. 5 quick beeps 3 times
will be generated when power is first applied to the unit. At this
stage, step back at least 3 feet from the controller and spout in
order to allow for proper calibration. Do not secure the lid/cover
until after calibration.
