Rectification
Aerator leaks or has an
inconsistent water flow pattern.
Aerator is dirty or misfitted.
Unscrew the aerator to check
rubber packing. Re-assemble the
aerator.
Sensor does not respond and a red
light is continuously on when the
Sensor Power On Procedure is
implementing.
There is some unexpected object
within detection range.
Check if there is any unexpected
object in the detection range and
remove it, such as tools, mirror, etc.
Before power supply is connected,
the water flows continuously when
the water valve is turned on.
Plunger of Solenoid Valve should
keep close when Sensor is not
detecting. The Plunger may be
accidentally opened due to
becoming stuck in transportation.
See installation procedures to
connect connection cable Assembly
and power supply correctly. As soon
as the power is connected, the
Solenoid Valve will close the
Plunger itself.
Sensor is connected with solenoid
valve and power supply. When
the water valve is turned on, the
water flows continuously without
object within the detection range.
The plunger of solenoid valve keeps
open abnormally because it
is obstructed by debris or faulty
Sensor.
Firstly change a new solenoid
valve. If the water still flows
continuously, then change a new
Sensor.
The default detection range is not
desirable for your use.
The default detection range
maybe not satisfied for some
particular circumstance.
Please refer to the chapter –
Detective Range Adjust Procedure.
