•Metered option to satisfy local codes for public bathrooms
•No temperature control –water should be pre-tempered
Specifications:
•Working water pressure: 20 PSI to 85 PSI
•Working water temperature: 45°F to 120°F
•Working environmental temperature: 35°F to 100°F
•Flow Rate: 1.2 GPM
•IP55 water and dust protection
•6V CR-P2 lithium battery (included)
•12 second metering cycle (WTM2 and WPM4 only) provides 0.24 gallons per cycle
•Shipping weight (lbs.): 10
•Shipping dimension (in.): 29 x 12 x 4
Note:
•DO NOT USE PLUMBER’S PUTTY ON ANY OF THE BRASS COMPONENTS
This will cause the finish to tarnish and void the warranty. A non-corrosive Alkoxy Silicone is
recommended.
•DURING SWEATING OF LINES DO NOT OVERHEAT CASTING
Overheating may cause damage to internal mechanism and void the manufacturer’s warranty as well
as increase the risk of scalding.
•COPPER ADAPTORS MAY BE REQUIRED TO COMPLETE YOUR INSTALLATION

Installation
1. Flush the lines of all dirt and debris.
Note: Failure to completely flush lines will cause valve failure and will void the warranty.
2. Close water supply.
Note: Refer to Diagrams A and B for Steps 3 –4.
3. Position Electrical Box (5) so the top is within 12” of the desired spout position and secure with 2
Wood Screws (8). Drywall Anchors (9) may be used if securing to drywall.
4. Position Solenoid Bracket (4) so the top of Solenoid Valve (3) is withing 28” of the top of Electrical
Box (5). Secure with 2 Wood Screws (8). Drywall Anchors (9) may be used if securing to drywall.
Note: There must be access to Electrical Box (5) and Solenoid Valve (3) after the wall is closed and
installation is complete.
Note: Refer to Diagrams B and C for Steps 5 –8.
5. Connect Solenoid Adapters (6) to Solenoid Inlet (11)and Solenoid Outlet (12).
6. Slide Solenoid Valve (3) into Solenoid Bracket (4). Solenoid should be oriented with inlet on bottom
and outlet on right, as shown.
7. Connect Solenoid Wire (14)to Solenoid Wire Connector (13). Run Sensor Wire (15)to the spout
connection and connect to Connecting Tab (17)on Spout Adapter (2).
8. Route Sensor Wire (15)and Solenoid Wire (14)so they do not come in contact with each other, with
the piping or with any other metal. Wall Clips (10) may be used to assist with wire routing.

Note: Refer to Diagrams B, C and D for Steps 9 –10.
9. Connect the premixed water supply to Solenoid Adapter (6) on Solenoid Inlet (11) using nipples and
fittings as needed.
10. Connect nipples and fittings from Solenoid Adapter (6) on Solenoid Outlet (12)to Spout Adapter (2):
a. Spouts from Group A require the male side of Spout Adapter (2) to extend ½” beyond the
finished wall. See Diagram D, Group A.
b. Spouts from Group B require the male side of Spout Adapter (2) to be recessed ½” behind the
finished wall. See Diagram D, Group B.
c. Spouts from Group C require the female side of Spout Adapter (2) to be recessed ½” behind
the finished wall. See Diagram D, Group C.
d. Make sure Sensor Wire (15)does not wrap around the nipple.
e. Connecting Tab (17) may be bent for easier installation or for better clearance.

11. Loosen 4 screws on front of Electrical Box (5) to remove front cover. Insert Battery (7) into Electrical
Box (5) (+ to +).
12. Red LED (16) will light and initial calibration will begin. After about 5 seconds, Red LED (16) turns off
indicating initial calibration is complete.
13. Open water supply and activate faucet so water runs through Spout (1). Make sure solenoid operates
correctly and check all connections for leaks:
a. For WT1, touch Spout Adapter (2) to turn on. Remove hand and check for leaks. Touch again
to turn off.
b. For WTM2, touch Spout Adapter (2) to turn on. Remove hand and check for leaks. Flow will
turn off automatically after about 12 seconds.
c. For WP3, move hand near Spout Adapter (2) to turn on and leave hand near Spout Adapter
(2) while checking for leaks. Remove hand to turn off.

d. For WPM4, move hand near Spout Adapter (2) to turn on. Remove hand and check for leaks.
Flow will turn off automatically after about 12 seconds.
14. Remove Battery (7) and turn supply back off.
15. Once solenoid has been tested, proceed to close wall. Make sure to leave access to Electric Box (5)
and to Solenoid Valve (3).
16. Connect Spout (1) to Spout Adapter (2). Refer to Diagram D.
17. Replace Battery (7) into Electrical Box (5) (+ to +).
18. Red LED (16) will light and initial calibration will begin. After about 5 seconds, Red LED (16) turns off
indicating initial calibration is complete. Replace front cover and tighten screws.
Note: Do not touch the faucet during initial calibration. If faucet is touched, remove battery and
return to Step 17.
19. Open water supply and activate faucet so water runs through Spout (1). Check all connections for
leaks.
20. Activate faucet 10 times for final calibration:
a. For WT1, touch Spout (1) to turn on. Remove hand and allow to run for 10 seconds. Touch
again to turn off. Wait 10 seconds before next activation.
b. For WTM2, touch Spout (1) to turn on. Remove hand and allow to run until it turns off
automatically, about 12 seconds. Wait 10 seconds before next activation.
c. For WP3, move hand near Spout (1) to turn on and leave hand near Spout (1) to allow to run
for 10 seconds. Remove hand to turn off. Wait 10 seconds before next activation.
d. For WPM4, move hand near Spout (1) to turn on. Remove hand and allow to run until it turns
off automatically, about 12 seconds. Wait 10 seconds before next activation.
Note: Sensor continuously learns environment as it is used. It may take up to a week of regular use to fully
calibrate.
Cleaning
1. To clean the spout, press once on White Button (16) to enter cleaning mode for 30 seconds. Red LED
(16) will begin flashing twice repeatedly.
2. During this time, spout may be cleaned without water turning on by touch or proximity.
3. When cleaning mode ends, Red LED (16) will stop flashing and operation will return to normal.
