Product Descripon
• This sensor tap is designed to turn on with sensor acvaon and o when hands are removed.
• Features a micro-computer infrared sensor control module, low consumpon microprocessor chip with stable perfor-
mance and high an-interference.
• Automacally calibrates sensing range according to the environment and stores this in the electronic chip.
• A water saving aerator is used in the faucet to prevent water splash back and allow for a so ow.
• Supplied with integrated DC 6V baery pack.
• The faucet has been precisely manufactured and tested, ensuring the quality of the product sases internaonal
standards.
Pre-Install Instrucons
Please choose an appropriate basin before installaon, avoid basins with strong reecve surfaces.
The sensor tap should be installed 250mm minimum above the washbasin.
Please ensure all pipes have been ushed for at least 60 seconds and are clear of dirt
and impuries (water must be clear).
Installaon must be in accordance with the Naonal Plumbing and Drainage standard – AS/NZS 3500.
When installing/removing baery's remove the sensor rst then the baery pack.
Do not use force when unplugging wires and removing the baery pack.
Ensure the ow adjustment is set correctly for your water pressure
Specicaons
*AA Alkaline baeries must be maximum 14mm in diameter. If it seems you are forcing the baeries please choose a dierent brand as AA
baeries can range between 13.5 and 14.5mm in diameter. We recommend Energizer Max E91 AA baeries.
*To reprogram sensing range use oponal remote 673-100R.

Technical Data
1. Invisible light rays are connuously emied from the faucet sensor.
2. When the user’s hands comes into range of the senor detecon zone, the solenoid valve is acvated.
3. Aer the user removes their hands, the valve closes.
4. The circuit will automacally reset for the next user.
5. If an object is in view for 30—60 seconds, the faucet will automacally shut o. The faucet will remain o unl the ob-
ject is removed.
Installaon
 Leave a hole of G1/2’ in diameter, 25mm inner thread depth in the wall (Figure 1).
 Rest the thread end of the faucet with thread sealing tap into the G1/2’ thread hole. Use a spanner to x it to avoid
leakage of water (Figure 2).
 Open the cap of the faucet by twisng an-clockwise with your hand (Figure 3).
 Take out the baery housing and install baeries. Once the baeries are installed, return the baery holder into posi-
on and put the sensor back into the faucet immediately. When the LED light does not ash, remove the sensor and
plug in the solenoid valve to accurately adjust the sensing distance (Figure 4).
 Connect the solenoid valve and the sensor. The faucet is now ready for use (Figure 5).

Fault Check
Before fault checking: please make sure the installaon distance is adequate and correct by referring to the Pre-
installaon instrucons.
The LED indicator will light up twice and then stop once aer the baeries are installed. To conrm the sensor is work-
ing, place your hand within the sensing range and check that the LED indicators lights once.
Problem The faucet has no water ow and there is no LED indicator light when within the sensing range
Cause The baeries are not supplying electricity to the sensor.
Soluon 1 Conrm the baeries have been correctly installed. Check that the posive pole is connected to “+” mark on
the plasc baery box. Check that the negave pole is connected to “-“ mark on the plasc baery box. Con-
rm the baeries are the correct size as per this manual and have not been forced.
Soluon 2 If the LED indicator does not light up and power is conrmed, replace the sensor control module.
Problem The faucet has no water ow and there is a LED indicator light when within the sensing range
Cause 1 Inadequate electricity supply.
Soluon Place hands under the sensing range for >5 seconds. If the LED indicator blinks every 1.5 seconds there is in-
adequate electricity.
Cause 2 Solenoid valve components are defecve.
Soluon
The LED indicator should spark for 2 seconds and then turn o. Place your hands within the sensing range, if
the LED indicator lights up once but you can not hear the audible “click” sound from the sole-noid valve,
please check the connecons between the sensor control model and solenoid valve. If the connecons are
good, change the solenoid valve components.
Problem The faucet has low water ow
Cause Low water pressure or water supply stop(s) are parally closed.
Soluon Refer to installaon step 3—at this point, increase water pressure and open the water supply stop (s) fully.
Problem The faucet has water ow but does not close completely
Cause 1 The solenoid valve is blocked by debris.
Soluon Disassemble the solenoid valve and clean it. Flush pipes and ensure water supply is free of debris. Change the
solenoid valve components if the problem is not solved.
Cause 2 Low water pressure.
Soluon Increase water pressure.
Problem The faucet has water ow but will not stop running
Cause Please conrm adequate electricity supply and solenoid valve connecons.
Soluon If the problem persists, check that the sensing range is adequate i.e. installed above the washbasin no less
than 25cm. Check that the basin surface is not stainless steel or reecve.

Cleaning and Maintenance
Regular cleaning is essenal to keep your tap looking its best.
Do not use abrasive or chemical cleaners (including chlorine to clean the faucet as this can dull or damage the lustre and
nish of the tap).
Wash only with soap water and dry with a clean so towel or microbre cloth.
When cleaning the general area please ensure you protect the faucet from any cleaning acids or uids as this can discolour or
remove the chrome plang where applicable.
The lter screen on the solenoid valve inlet should be cleaned regularly to avoid excessive blockage and obstrucon caused by
impuries resulng in low water ow.
