Recommended Tools: Adjustable wrench and 5/64” hex key wrench. INSTALLATION PROCEDURE Step 1: Remove grille and shut off water supply. Actuate sensor to relieve pressure in the system. Then, disconnect power from plug-in or hardwire transformer. Step 2: Remove bottom plate from fountain using 5/64” Hex key wrench. Step 3: Disconnect electrical connectors leading to transformer and solenoid valve. Step 4: Use adjustable wrench to remove brass nut from sensor threads taking care not to damage or lose any components. Remove cup washer and flange washer. Discard old sensor. Step 5: Ensure O-ring is on replacement sensor. Slide flange washer onto replacement sensor. Using flange washer as a guide, align replacement sensor into mounting hole. Slide cup washer onto sensor. Carefully tighten sensor onto mounting hole using brass nut. Do not overtighten and damage threads. Step 6: Reconnect electrical connectors to transformer and solenoid valve. Step 7: Reconnect power to transformer. Turn on water supply and adjust the bubbler’s flow using the black regulator mounted next to the solenoid valve. Clockwise adjustment increases flow and counterclockwise decreases flow. Finally, check fountain for leaks. Step 8: Clear the area in front of the sensor. Allow the sensor to calibrate for at least 10 seconds before operating. When the sensor is activated continuously for 30 seconds, the sensor will automatically shut off the water supply to the bubbler. To resume activation, remove obstruction and reactivate the sensor. This feature prevents flushing of water due to unintentional activation or vandalism. Step 9: Re-install bottom plate and grille.

SENSOR/SOLENOID TROUBLESHOOTING PROBLEM REPAIR CHECKLIST 1. Insufficient bubbler flow. a. Check that screwdriver stop is wide open. Direction can be counterclockwise or clockwise depending on style of shut-off valve. b. Verify minimum 30 psi supply pressure. c. Clean inlet strainer (if one is present). 3. No bubbler flow – red light in the sensor does not flash once when user’s hands are within the sensor’s range a. b. Unit is in Security Mode. Sensor is picking up reflections from a foreign object. Eliminate the source of reflection. 4. No bubbler flow – red light in the sensor flashes once when user’s hands are within sensor range. a. b. c. d. Connectors between electronic unit and solenoid are disconnected. Reconnect the connectors. Debris or scale in solenoid. Shut off water and power. Unscrew solenoid, pull out the plunger and spring from the solenoid and clean them. Use scale remover if needed. When replacing the plunger, ensure the spring is oriented vertically. The central orifice in the diaphragm is plugged or the diaphragm is torn. Clean the orifice or replace the diaphragm. The water supply pressure is higher than 115 psi. Reduce the supply water pressure. 4. Continuous bubbler flow – sensor flashes once when user’s hands are within the sensor’s range. a. Debris or scale in solenoid diaphragm. Clean the orifice or replace diaphragm per 4b-c. 5. Continuous bubbler flow – red light in the sensor does not flash once when user’s hands are within sensor range. a. b. Sensor is dirty or covered. Clean or eliminate case of interference. In this event, the security time will stop flow. Sensor is picking up reflections from the washbasin or another object. Decrease the range or eliminate the cause of reflection. 6. Repeated clogs in strainer. a. Install water filter in supply line. 7. Bubbler does not activate. a. Check wiring harness. Replace if necessary. b. Check solenoid valve. Replace if necessary. c. Replace sensor. d. Check transformer for 9V at output terminals; replace if necessary. © 2021 Haws® Corporation – All Rights Reserved HAWS® and other trademarks used in these materials are the exclusive property of Haws Corporation.
