LK722AC Sensor-operated, non-mixing (tempered water),
backsplash-mounted gooseneck faucet with adjustable sensor
eyes. A continuous beam is emitted from sensor. The sensor
faucet is activated by user placing hands under the spout.
Tempered water will flow as long as hands remain within sen-
sor range. When hands are removed, the water stops automat-
ically based on shut off delay settings. The sensor then resets
and is ready for the next user. AC powered, chrome plated -
solid brass body construction and 12-3/4" (324mm) high (bot-
tom of base to top of spout), 8-3/4" (222mm) from aerator to
base, 5-3/8" (137mm) reach C.P. spout with 2.0 gpm laminar
flow control on spout end. Includes vandal-resistant, water-
resistant sensor control module with armored vandal-resistant
control and power cables. LK730 wire lead allows contractor to
connect each control box to one LK727 multi-unit power
adapter. Depending on the location of the LK727, 20-22 gauge
wire (not supplied) may be required from LK730 to LK727.
Slow-closing piston operated solenoid valve, in-line filter with
clean out trap, and 3/8" (10mm) copper fittings for supply tube
