IRC urinal flush control valve installation guide 1 Introduction the infrared urinal flush control (IRC) valve automatically manages the supply of water to a urinal cistern. ­ n detection of movement in the washroom, O the IRC activates a 30 minute cycle allowing water to flow into the cistern. During the last five minutes of the 30 minute cycle the sensor ‘looks’ for movement. If no movement is detected during these five 3 YEAR warranty * 3 minutes the valve will close. If, however, the sensor does detect movement a new 30 minute cycle is activated. If no movement is detected for 12 hours the IRC will activate a hygiene cycle.

You will need to match these numbers when wiring the sensor i.e.‘1’ to ‘1’ and ‘2’ to ‘2’. Place the plug on the solenoid and secure in place with screw D . NOTE: Cable Specification: CSA =1mm² Length = 10m (Max.) from sensor to solenoid 5 Commissioning Once all is installed, the flow rate will need to be adjusted to suit the particular installation. Using the flow regulator on the bottom of the solenoid you can either increase or decrease the flow of water. Ideally the cistern should flush once every 30 minutes. Flow regulator Adjust the valve by turning the screw at the base of the brass valve body clockwise to reduce the flow and anti-clockwise to increase the flow. NOTE: Use the table below to set your cistern to flush once every 30 minutes. Adjust the flow through the valve so it takes the time below to fill a measuring cup to 100ml. Cistern size Time to fill 100ml 4.5L 40 sec 9.0L 20 sec 13.5L 13.5 sec Clockwise: reduces the flow rate Anti-clockwise: increases the flow rate 0118 969 1611 | [email protected] | www.cistermiser.co.uk 8 6 Self-test mode Test button Sensor/LED 1 Press Test Button (Amber LED will illuminate). 2 Test cycle Valve Test Mode Valve opens and closes five times - amber LED will blink with every valve movement. Sensor Test Mode Valve closed for one minute. Body movement causes the amber LED to flash when detected. Check detection range by walking around the room to confirm the light flashing. After one minute the sensor test mode will finish and the sensor will revert to normal operation. Normal operation Valve remains open for a period of 30 minutes (green LED will flash) after which it will shut down. If, however, presence is detected within the last five minutes of the 30 minute cycle, the valve will reactivate a new cycle. LED sequence Valve open green LED flash once every 3 seconds (battery) green LED flash once every 2 seconds (mains) Low Power red LED flash Fault double red LED flash Start up / test cycle amber LED 0118 969 1611 | [email protected] | www.cistermiser.co.uk 9 7 Power connection Cistermiser IRC can be powered by either batteries or mains electricity. Fitting batteries to a mains connected unit will offer back-up power in case of mains supply failure. NOTE: When fitted directly onto pipework only use battery power pack. 8 Usage advice and specification power Mains Supply: Nominal 230V 50Hz 20mA. Battery Supply: 230V AC +/-10% 20mA nominal, 50mA max. Batteries (recommended): Duracell Plus (Gold Top) MN1500 Capacity 2700mAh. Operating Life: Up to three years with recommended batteries depending on washroom usage. solenoid valve 6V Latching Valve: UK WRAS approved.

If supply pressure is above 6.0 bar, fit a pressure reducing valve. 0118 969 1611 | [email protected] | www.cistermiser.co.uk 10 9 Frequently asked questions test mode does not function No power Ensure unit is powered. Change batteries if battery powered; ensure mains electrical power is functioning if mains powered. Power supply fault Disconnect one source of power and check by pushing the test button. When the sensor is mounted directly on the valve it should be battery powered ONLY. Also check remote wiring if sensor is remote from valve. no water passing the valve Water supply Ensure water supply is turned on and reaching the valve. The valve comes with a factory fitted 1.5mm insert fitted for water pressures of 2 - 6 bar. If your water pressure is within this range and the optional 3mm insert has been fitted then revert back to the 1.5mm insert. The 3mm insert is for use with water pressures of 0.1 - 2 bar. Blockage on the outlet pipe If a petcock or bibtap has been fitted, ensure it is removed or fully open. Instructions state there should be no restriction after the valve. Mesh filter blocked on inlet Remove valve. Check to ensure filter on the inlet side of the valve is clear. Flow regulator Ensure the flow regulator is fully opened; when the valve is letting water run, turn down to the required flow rate. High water pressure (above 6 bar) Fit pressure reducing valve before the IRC valve. No power Ensure unit is powered. Change batteries if battery powered; ensure mains electrical power is functioning if mains powered. 0118 969 1611 | [email protected] | www.cistermiser.co.uk 11 water is continuously flowing through the valve User perception Once activated the valve remains open for a period of 30 minutes and will reactivate if someone comes within the range of the sensor in the last five minutes of the 30 minute period. The valve appears to work continuously as long as someone is in the washroom. No power The power has failed while the valve is in the ‘open’ position. Ensure the unit is powered. Change batteries if battery powered; ensure mains electrical power is functioning if mains powered. Valve incorrectly fitted Ensure the arrow on the brass body is pointing in the direction of water flow. the valve remains shut when the room is occupied but opens at other times Incorrect remote wiring If the valve and sensor have been set up remotely, ensure the remote wiring is wired as follows: ‘1’ to ‘1’ and ‘2’ to ‘2’. If you find the wiring is connected ‘1’ to ‘2’ and ‘2’ to ‘1’ then the valve is working in reverse. water flow rate through the valve seems to be very slow Flow regulation Increase the flow rate by turning the flow regulator anti clockwise until you reach your desired flow rate; ideally it should fill the cistern once per activation and then flush. See Step 5 ‘Commissioning’ Mesh filter blocked Check to ensure filter on the inlet side of the valve is clear. Flow restrictor/insert The valves comes with a factory fitted 1.5mm diameter insert fitted for water pressures of 2 - 6 bar; this should be changed over to the 3mm insert (for water pressures of 0.1 - 2 bar) to allow more water through. See Step 3 ‘Valve Installation’. water flow rate through the valve is fast and the cistern is flushing too frequently Flow regulator Decrease the flow rate by turning the flow regulator clockwise until you reach your desired flow rate. Ideally it should fill the cistern once per activation (i.e. every 30 minutes) and then flush. See Step 5 ‘Commissioning’. 0118 969 1611 | [email protected] | www.cistermiser.co.uk 12 9 Frequently asked questions there is a leak around the solenoid If the black bracket/solenoid has been removed from the block and rotated for flow orientation the ‘O’ ring seal at the join may be dislodged or lost If dislodged, re-position. If lost; call Cistermiser. I have just changed the batteries and there is no power to the unit Battery orientation Check battery orientation; ensure there is not excessive corrosion on battery terminals.

Frequently asked questions
The IRC valve uses a PIR sensor to detect movement in the washroom. When movement is detected, the valve activates a 30-minute cycle, allowing water to flow into the urinal cistern. If no movement is detected during the last five minutes of the 30-minute cycle, the valve will close. If movement is detected during these five minutes, a new 30-minute cycle is activated. If no movement is detected for 12 hours, the IRC will activate a hygiene cycle.
The hygiene cycle is a flush that occurs after 12 hours of inactivity to ensure the urinal is kept clean and hygienic.
You can adjust the flow rate of the valve by turning the flow regulator on the bottom of the solenoid. Turning the screw clockwise reduces the flow rate, and turning it counter-clockwise increases the flow rate. The cistern should flush once every 30 minutes, ideally.
The IRC valve can be powered by either batteries or mains electricity. You can also choose to power it by both, which will provide backup power if the mains supply fails.
To test the IRC valve, press the test button. This will activate the valve test mode, which will cause the valve to open and close five times. The sensor test mode will run for one minute, and body movement will cause the amber LED to flash. After one minute, the sensor test mode will finish, and the sensor will revert to normal operation.
