Model EWMA7220SACC
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 sensor range. When hands are removed, the water stops automatically 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 (bottom 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, waterresistant 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
furnished by contractor. Control circuit is solid state, has
adjustable sensor range (6" [152mm] preset to 30" [762mm]),
shut off delay preset at 1 second and field adjustable to 2, 4 or
8 seconds, and automatic time-out feature (to prevent sink
overflow) is preset at 0 seconds and is field adjustable to 15, 30
or 60 seconds.

(38mm) O.D. stainless steel tailpiece.

brass body 1/2" (13mm) SWT inlets and outlet connections,
check valves on inlets and a mixed temperature range of
80°- 120°F. Certified under ASSE1016.
