Troubleshooting Guide
Install issues due to drainpipe
obstructions
Drain pipe or other plumbing under the
sink or countertop is in the way.
Use the optional flexible 6” extension hose (J). It is to be placed between the spout shank (A) and the outlet
of the valve control module (K). The faucet components can then be assembled off to one side of the drain or
other plumbing. Do not add any plumbing or piping components not Included in this kit to the faucet installation
as it may cause the faucet to not function or sense properly.
Faucet not working
(No flashing red LED located
on valve
control module)
Batteries not inserted
correctly
Improper or poor connection to
power supply
Remove cover from battery box (Z) check that the batteries (DD) have been inserted to the correct orientation
and are making connection to the contacts. Refer to the battery icons located on the base of the battery box tray.
Check that the connection from the battery box is fully inserted into the female connector on the valve control
module (S) and assure the connector round thumbnut is fully fastened.
Faucet not working and no
water flows
when activated
(Red LED is flashing)
Low batteries
Water source valves turned off
Sensor shorted to ground or unit
unable to calibrate
Improper ground connection
Broken or corrupt sensor wire or
defective valve control module
electronics.
If red indicator is flashing 5 times every 4 seconds, replace with new Alkaline batteries (DD).
Open water source valves and check that there is water flow.
If red indicator is flashing once or multiple times every 4 seconds, there is a problem with the installation and the
sensor is shorted. To verify the valve control module is working correctly, carefully disconnect the black sensor
wire from the connection washer (N). With the wire disconnected, touch the connector at the end of the black
wire with your fingers. The sensor should activate and water should come on. Let go of the connector and the
water should shut off. If the unit works as described above, it malfunctions when you reconnect the black sensor
wire to the spout assembly, then there is an error in the spout and cover plate installation. If the faucet does not
activate as described when touching the sensor connector, then you have a grounding issue or there is a broken
sensor wire (see troubleshooting below).
If you can touch any of the steel braided supply hoses, the brass fitting on the valve control module, or the mixing
valve and it activates the unit, there is improper earth grounding (GG). Verify that the ground clamp (GG) has
been installed and recheck the connections. Verify the clamp is tightly fastened directly to the copper pipe for a
proper ground connection. Press reset button on valve control module after making any adjustments.
If the connector has broken off of the black sensor wire or the valve control module appears to be defective
please contact Technical Concepts. Do not attempt to repair the valve control module (S) or sensor wire.
Intermittent cycling and/or water
runs on after actuation
Poor sensor washer and
wire connection
Verify the brass nuts (O) that fasten the connection washer (N) are fully tightened. Reconnect the sensor wire
to the washer. Press reset button on valve control module after making any adjustments
Insufficient ground connection
SST faucet components are in
contact with metal parts of the sink
or plumbing.
Be sure that all of the SST faucet components (cover plate, white plastic screw spacers, brass shank, metal
washer, braided hoses) or any components for the sink (metal sink lip / mounting hardware) or countertop (i.e.
metal support brackets / structural parts) are not in contact and are spaced from each other. Press reset button
on valve control module after making any adjustments
Verify that the earth ground clamp (GG) has been installed and recheck the connections. Verify the clamp is tightly
fastened directly to the copper pipe for a robust ground connection. Press reset button on valve control module.
Intermittent cycling and /or
faucet actuation is overly
sensitive
Isolation parts are not installed or
not installed correctly.
If you can touch the sink and the faucet activates, the unit installation is improper. Check that isolation
components (HH) are used and installed correctly. If the sink is of a metal composition, verify the sink
ground connection (GG) is in place and installed properly.
Faucet doesn’t shut off after
you pull your hands away
Check that the cover plate ground (HH) is assembled to the threaded cover plate studs and is connected to the
U-tab on the valve control module (S). Press reset button on valve control module after making any adjustments.
Drain grounding not connected or
assembled.
There is sensor short to ground or
unit is not calibrating.
Press reset button located on the face of the valve control module (S). The valve should close and the
water will stop running. Let unit recalibrate for 20 seconds and verify faucet activation. If water continues to
run, then there is an error in the installation and grounding connections (see troubleshooting above).
Water stays on
Dial set to the “open” position or not
turned to the full “auto” position
Turn the auto/open valve dial on the side of the valve control module (S) fully to the “auto” position (until it
hits the stop) and actuate the faucet by placing your hand near the spout. Water should stop running and
unit will return to the normal idle operation mode when you remove your hand from the spout.
Turn off water source valves. Remove aerator from end of the spout (A) and examine for dirt and particu-
lates. Inspect and clean the dirt filter (V). Reinsert filter and turn water source back on. Actuate faucet
several times without the aerator installed to flush any debris from the valve mechanism until dripping has
ceased. Reinstall aerator.
Turn the auto/open valve dial on the side of the valve control module (S) fully to the “auto” position (until it hits
the stop) and actuate the faucet several times by placing your hand near the spout. Water should stop running or
dripping and unit will return to the normal idle operation mode once you remove your hand from the spout.
Dial not turned to the full
“auto” position
Debris or particulate matter is
trapped in valve
Leaky faucet
Check that the water supply valves are fully open and the lines are not restricted by any obstructions. If the
flow rate is not as desired contact us for optional sized aerators.
Water Supply Restricted Minimal Water Flow
Install a mixing valve (X). Adjustments can be made to the valve by resetting the temperature control knob.
If more precise or anti scald water temperature control is required, the optional thermostatic control valve
(Y) may need to be purchased.
Turn the auto/open valve dial on the side of the valve control module (S) to the “open” position to flush
faucet. This is a mechanical override of the automatic sensing and will set the valve to a constant open po-
sition. Once the water is flushed as required, turn the auto/open valve dial back fully to the “auto” position
(until it hits the stop) and cease water flow by placing hand near faucet and pulling hand away.
Required hygiene or sanitary
procedure
No mixing valve installed or mixing
valve needs adjustment
Flushing faucet for
regulatory protocol
Water temperature too
hot or cold
