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.
­
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, 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.

3 Valve installation
Install the valve on the 15mm pipe feeding
the cistern.
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.
To change the direction of the valve remove the
screws from the black valve body, turn the valve
around and screw the valve back in.

3mm orifice should only be fitted when
the water supply is from a tank or is at low
pressure. (Refer to chart below)

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.
Clockwise:
reduces the
flow rate
Anti-clockwise: increases the
flow rate

NOTE: Use the table below to set your

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.

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.

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.

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’.

urinal flushing
hydraulic valve
An automatic urinal flush control
valve which reduces water
consumption and odours. The
valve uses a simple patented
mechanism which prevents
water waste by ensuring that
the auto-flush cistern is only
filled, and can only flush, when
the washroom is used.
infrared control

This valve automatically
manages the water supply to
the urinal cistern and reduces
water consumption by up to
80%. The PIR sensor detects
movement and activates the
solenoid valve, allowing water
into a urinal cistern.
