Step 6: Connecting electrical and supply tubing
WARNING: The Express® must be connected to the 24 VAC Class II plug-in
transformer provided. Connection to 110 VAC can result in
personal injury and/or damage to the electronics.
CAUTION: Connection of leads other than shown may cause permanent
damage to the sensor.
1. Snap the sensor circuit plug from the sprayhead into the solenoid circuit plug located on the
valve bracket.
2. Snap the transformer circuit plug into the female transformer circuit plug located on the valve
bracket.
3. Insert the three sprayhead supply tubes into the three solenoid tube connectors by loosening the
compression nut and firmly pushing the tubing into the tube connector until the tubes are fully
seated, then re-tighten the compression nut hand-tight plus two turns with a wrench. (Figure 7).
4. Align the valve bracket mounting screws with slots on the frame. Let the valve bracket slide
down to lock into place.
5. Turn on the water supply to the Express® and check for leaks.
6. Turn on the electrical power to the electrical outlet and pass your hand in front of each station’s
sensor until all the air is purged from the lines and water is flowing smoothly.
7. After testing is complete, reinstall the main frame access panel to frame. Fasten panel with the
eight #10-24 x 1/2" flat head Torx screws and #10 finish washers provided (Figure 3, page 7).
