Infrared Taps

Please click the question/ problem below to view the answer.

No water from tap / spout
The sensor is flashing red once a second Low battery. Change batteries.
The sensor is not flashing at all when hands are in sensing range. No power. Change batteries if battery powered. Ensure power is switched on and is reaching the tap. Check all electrical connections.
The sensor is flashing green once a second when hands are in sensing range but there is no water. Water supply. Ensure water supply has been turned on and there is good working pressure. Minimum working pressure 0.5 bar.
Filter blockage (Novatap). Ensure flexible connector has not been twisted. Ensure filter in the flexible connector is not blocked. Ensure the spout is clear.
Continuous flow of water or dripping from the tap
The sensor is not flashing at all when hands are in sensing range. No power. The power has failed whilst the solenoid tap is open. Change batteries if battery powered. Ensure power is switched on and is reaching the tap, check all electrical connections.
The sensor is flashing green once a second when hands are in sensing range. No power. The power has failed whilst the solenoid tap is open. Change batteries if battery powered. Ensure power is switched on and is reaching the tap, check all electrical connections
Water supply. Ensure water pressure is not above maximum working pressure of 6 bar or below minimum working pressure of 0.5 bar.
Novatap
Debris or scale in diaphragm/solenoid. Remove aerator using key supplied then place hands in sensing range and let water flow for approximately 2-3 minutes, this should clear any debris. (The flow will automatically shut off after 1 minute; when this happens, remove hand and reactivate). If this does not solve the problem contact Cistermiser Technical Department.
Novaspout
Debris or scale in diaphragm. Isolate water supply to the valve. Remove wires attached to solenoid. Undo 4 screws and remove. You will have access to the diaphragm (note orientation for when reinstalling) flush under cold water and visually inspect. Reinstall Diaphragm has been damaged by debris. Call Cistermiser for further advice.
Water flow diminishes
The sensor is flashing green once a second when hands are in sensing range. Filter or aerator is blocked with scale or debris. Remove aerator using key supplied, clean and reinstall. Check filters prior to the aerator i.e. TMV (Novatap check filter within the flexible connector).
Water flow as expected and then diminishes immediately
The sensor is flashing green once a second when hands are in sensing range. TMV/water pressure issue. Ensure TMV is operating correctly and water pressures are suitable for TMVs installed.
Water is always cold
The sensor is flashing green once a second when hands are in sensing range. TMV/hot water plumbing issue. Ensure TMV is set up correctly; hot water-runs in buildings can sometimes be lengthy. There may be a short delay until hot water is dispensed from the tap.
Other alarms
Double red flash Faulty wiring. Check wiring. Faulty solenoid. Call Cistermiser for advice.
Red flash once every second. Low or no battery power. Change batteries. If operated by mains power, contact Cistermiser.
Low battery power. Change batteries. Sensor covered or heavily scratched. Uncover sensor or polish out scratches.
