1. Introduction
The infrared urinal flush control (IRC) valve automatically manages the supply of water to a urinal cistern.
The IRC is only to be used in conjunction with a cistern and is suitable for fixing to solid or cavity walls and false ceilings, or directly onto pipework.
The IRC sensor unit can be installed separately from the solenoid valve.
Adjust valve to fill in 30 min
(See Page 11 Section 6)
0 MIN
Occupancy detected - valve opens for 30 min
After 25 min infrared sensor looks again for occupancy
Cistern flushes when full
30 MIN
On detection of movement in the washroom, 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 minutes the valve will close. If the sensor detects movement a new 30 minute cycle is activated. If no movement is detected for 12 hours the IRC will activate a hygiene cycle.

3. Valve installation
Install the valve on the 15mm pipe feeding the cistern.
It is good plumbing practice to install an isolation valve upstream from the
IRC valve.
NOTE: The valve should be positioned with the directional arrow pointing in the same direction as the flow of the water with the solenoid on top.
NOTE: There should be no restriction, such as a petcock or bibtap, after the valve.
Changing the flow direction
In some installations the solenoid head may be facing the wall and the sensor cannot be fitted. You can turn the head around using the following action:
• Remove the solenoid coil clip (1)
• Lift the solenoid (2) and rotate the valve body (3)
• Replace the solenoid coil clip (1)

NOTE: Where one cistern feeds multiple urinal outlets, ensure the urinal outlets are evenly distributed and balanced so the cistern gives equal flush.
NOTE: One IRC is required for every cistern.

6. 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.
Adjust the valve by turning the screw at the base of the brass valve body; clockwise to reduce the flow and anticlockwise to increase the flow.
Flow regulator
Clockwise: reduces the flow rate
Anti-clockwise: increases the flow rate
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.

7. Test & economy modes
Test cycle
When the test button (2) is held down for over 2 seconds and less than 10 seconds then released the unit will go into Test mode.
It will first test the valve and the sensor will show amber, flashing each time the valve opens or closes. It will perform this action 5 times.
The unit will then test the sensor and only flash amber to confirm that it picks up any motion. Your movement around the room will highlight this is working.
The test cycle can be halted at any point by pressing the Test button and releasing straight away.
Switching sensor mode
Holding down the test button (2) for longer than 10 seconds will switch between Normal and Economy modes.
Whilst the test button is held down the sensor light (1) will show the mode that it is in:
• Solid green indicates Normal mode
• Flashing green indicates Economy mode
30 MIN
Normal mode
When a presence is detected the valve will remain open for
30 minutes. Whilst in operation a single green flash will be seen.
15 MIN +
30 MIN
Economy mode
When a presence is detected the valve delays opening for
15 minutes and then will open for 30 minutes.
Whilst in operation a double green flash will be seen.
• If the sensor detects movement in the last 5 minutes of either mode’s 30 minutes cycle it will reactivate a new cycle.
• The unit is supplied in Normal mode.
• When powered down the unit will remember the mode it is in.
NOTE: At any point that the test button is pressed and released the valve will close until there is movement in front of the sensor.

No power
Power supply fault
Ensure unit is powered. Change batteries if battery powered; ensure mains electrical power is functioning if mains powered.
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
Blockage on the outlet pipe
Mesh filter blocked on inlet
Flow regulator
High water pressure
(above 6 bar)
Ensure water supply is turned on and reaching the valve. The valve is suitable for water pressures of 0.1 to 6 bar.
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.
Remove valve. Check to ensure filter on the inlet side of the valve is clear.
Ensure the flow regulator is fully opened; when the valve is letting water run, turn down to the required flow rate.
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.
Economy mode

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. Go through test cycle when power is restored.
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
Mesh filter blocked
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 6 ‘Commissioning’.
Check to ensure filter on the inlet side of the valve is clear.
www.cistermiser.co.uk 15
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 6
‘Commissioning’.
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. Ensure batteries are a reputable brand.
