Guide •BATTERY OPERATED FAUCETS
1. PROBLEM: Module emits audible “BEEPs” when activated.
CAUSE: Battery power is nearly exhausted.
SOLUTION: To ensure proper operation, insert four (4) new C-size
Alkaline batteries. Check that the orientation of each
battery matches the positive (+) and negative (–)
symbols shown in the bottom of the Battery
Compartment. Reattach Battery Compartment to Control
Module.
2. PROBLEM: Sensor is activated but faucet does not deliver water.
INDICATOR: Module DOES NOT produce audible “BEEPs”.
CAUSE: Battery power is fully exhausted.
SOLUTION: To ensure proper operation, insert four (4) new C-size
Alkaline batteries. Check that the orientation of each
battery matches the positive (+) and negative (–)
symbols shown in the bottom of the Battery
Compartment. Reattach Battery Compartment to Control
Module.
CAUSE: Batteries are not installed properly.
SOLUTION: Check that the orientation of the batteries match the
positive (+) and negative (–) symbols shown in the
bottom of the battery compartment. Reattach the Battery
Compartment to the Control Module.
CAUSE: Solenoid Valve Module is defective.
SOLUTION: Replace EBF-11-A Solenoid Valve Module.
INDICATOR: Module produces audible “BEEPs” when batteries are installed and
after 30-second calibration procedure, but NOT when a target is
placed in the detection zone of the Sensor.
CAUSE: Fiber Optic Cable is not connected correctly to Solenoid
Valve Module or was not connected when batteries were
installed.
SOLUTION: Reconnect Fiber Optic Cable to Solenoid Valve Module.
Open Battery Compartment to reset electrical system.
Check that the orientation of each battery matches the
positive (+) and negative (–) symbols shown in the
bottom of the battery compartment. Reattach the Battery
Compartment to the Control Module.
CAUSE: Fiber Optic Cable is defective.
SOLUTION: Replace EBF-179-A Sensor Cable, EBF-1009-A Sensor
Cable, or EBF-10-A Faucet/Sensor Assembly.
CAUSE: Solenoid Valve Module is defective.
SOLUTION: Replace EBF-11-A Solenoid Valve Module.
INDICATOR: Module produces audible “BEEPs” when a target is placed in the
detection zone of the Sensor and Solenoid Valve produces an
audible “CLICK”, but NO water flows.
CAUSE: Water supply to faucet is not open.
SOLUTION: Open supply stop(s).
CAUSE: Back Check is installed backwards.
SOLUTION: Reinstall Back Check(s).
CAUSE: Solenoid Filter is clogged.
SOLUTION: Remove, clean, and reinsert. Replace with EBF-1001-A
or EBF-1004-A Solenoid Filter Kit if necessary.
CAUSE: Aerator or Spray head is clogged.
SOLUTION: Remove, clean, and reinsert.
INDICATOR: Module produces audible “BEEPs” when a target is placed in the
detection zone of the Sensor, but Solenoid Valve does NOT produce
an audible “CLICK” and NO water flows.
CAUSE: Solenoid Valve Module is defective.
SOLUTION: Replace EBF-11-A Solenoid Valve Module.
3. PROBLEM: Faucet delivers only a slow flow or dribble when
Sensor is activated.
CAUSE: Water supply valve is partially closed.
SOLUTION: Open the Supply Stop(s) completely.
CAUSE: Solenoid Filter is clogged.
SOLUTION: Remove, clean, and reinsert. Replace with EBF-1001-A
or EBF-1004-A Solenoid Filter if necessary.
CAUSE: Aerator or Spray head is clogged.
SOLUTION: Remove, clean, and reinsert.
4. PROBLEM: Faucet does not stop delivering water or continues to
drip after user is no longer detected (automatic shutoff fails even when batteries are removed).
CAUSE: Solenoid Valve has been connected backwards.
SOLUTION: Disassemble Solenoid Valve compression fittings at the
inlet and outlet positions. Water should flow from inlet
through the Solenoid Valve to outlet according to the
direction shown by the arrow on the side of the Solenoid
Valve. Reconnect the fittings in the correct orientation.
CAUSE: Solenoid Valve seat is dirty.
SOLUTION: Remove, clean, and reinsert Solenoid Filter. Activate
faucet several times to flush out dirt.
CAUSE: Solenoid Valve is dirty.
SOLUTION: Backflush by reversing water flow (opposite to the
direction shown by the arrow on the side of the Solenoid
Valve) through the Solenoid Valve. Reconnect the
compression fittings in the correct orientation.
Activate faucet.
CAUSE: Solenoid Valve Module is defective.
SOLUTION: Replace EBF-11-A Solenoid Valve Module.
5. PROBLEM: The water temperature is too hot or too cold on a
faucet connected to hot and cold supply lines
with two Back Checks.
CAUSE: Supply Stops are not adjusted properly.
SOLUTION: Adjust Supply Stops.
CAUSE: One Back Check is installed backwards.
SOLUTION: Reinstall Back Check.
NOTE: For some systems, a Thermostatic Mixing Valve may be required.
NOTE: BEEP sounds are emitted from the Solenoid Valve Module (not from the Spout of the
Faucet). For the first ten (10) minutes of operation (or after battery replacement), the unit
BEEPs every time the faucet is activated to indicate that range limits are set. To conserve
battery power, the unit will not BEEP again until it indicates low battery power.
Calibration Procedure: When the battery compartment is assembled to the valve module with
active batteries, the faucet initiates a self-calibration mode and uses BEEPs to indicate the
status of this mode. To prevent improper calibration, ensure that the Spout is centered
properly and that no targets are in the detection range of the sensor when the batteries are
connected. An initial series of BEEPs indicates that power is being supplied from the batteries
to the faucet. For the next thirty (30) seconds, the sensor determines the most suitable range
setting for its environment. Water will not flow from the faucet during this automatic range
calibration. After the range is calibrated, a second series of BEEPs indicates that the faucet is
ready for use. Under normal operation, this faucet adapts its range to changes in the
environment.
Battery Replacement Procedure:
Loosen security set screw on the
Coupling Ring with a 0.05” hex or
allen wrench. Unscrew Battery Compartment Coupling Ring. Remove Batter y Compartment. To
ensure proper operation, remove old batteries and insert four (4) new C-size Alkaline batteries.
Check that the orientation of each battery matches the positive (+) and negative (–) symbols
shown in the bottom of the Battery Compartment. Reattach the Batter y Compartment to the
Control Module by aligning the arrow on the Battery Compartment with the arrow on the solid
tab of the Solenoid Valve Module. Secure by tightening Battery Compartment Coupling Ring.
To deter unauthorized removal of batteries, use a 0.05” hex or allen wrench to tighten the
Security Set Screw on the Coupling Ring.
