STEP 6 - MAKING ADJUSTMENTS
(Optional: Only required if factory settings are not preferred)
• To move from operation mode into set-up mode: remove the plastic plug located in the rear of the sensor module and press the set-up
mode button once. A pencil or small screwdriver may be required. When done, place the plug back in the hole.
6.1 Adjusting Sensing Distances:
• Sequences of red lights will intermittently strobe across the sensor window, followed by a number of red lights which stay on to indicate
the current sensing distance.
Pre-set sensing distances are:
Water Closet
1 light
24"
2 lights
32"
3 lights
40" (factory set)
4 lights
48"
5 lights
56"
• A pulsating blue light on the far left of the sensor window will indicate if an object is detected. However, the sensing distance could be set
at a distance greater or shorter than the desired activating position.
• To ensure sensing distance is set to precise desired position, stand at desired activating distance.
• If the pulsating blue light is not present, press the electronic override button (the red lights will increment).
• Continuing to press the electronic override button will eventually loop the sensing distance back to 1 light (12" sensing distance for urinal,
24" sensing distance for water closet).
• Press the electronic override button until pulsating blue light is present. The blue light indicates that the sensing distance has been adjusted
to a position that is detecting you.
Water closet only:
• Now stand back and ensure that the pulsating blue light disappears when
you stand near the door of the water closet.
• Ensure that the door is not being detected as well. If so, decrease the range
increment by 1 light (this is achieved by pressing the electronic override button
until the lights loop back around to a setting that is one less the previous
setting).
• Once again, verify that the sensor is not detecting the water closet door. If
not, the sensor is now set at your desired position.
• The sensing distance for water closets can be set between 24" and 56", and
for urinals between 12" and 28".
• If all adjustments have been completed, press and hold down the electronic
override button for 5 seconds. For water closets, this will return the valve to
operation mode. For Urinals, this will advance the distance adjustment mode
into the 24 Hour Flush adjustment mode.
6.2 Adjusting 24 Hour Flush: (for Urinal applications)
• When 3 red lights in the centre of the sensor window are on, 24 hour flush
is on.
• When the red light in the middle of the 3 lights is off, the 24 hour flush is off.
• Press electronic override button to toggle between on and off mode.
• If all adjustments have been completed, press and hold down the electronic
override button for 5 seconds until all lights go out.
Factory Settings:
Flush volume adjustment:
Not Adjustable
1.6 U.S. gallons / 6 litres for water closets
1.27 U.S. gallons / 4.8 litres for water closets
1.1 U.S. gallons / 4.2 litres for water closets

0.13 U.S. gallons / 0.5 litre for urinal valves
The Regulating Screw (061024A, item #9) may be adjusted, according to job conditions and fixture installed to the proper water volume to
flush that particular fixture (except -6, -48, -42, -19 and -05 models which are not field adjustable).
NOTE: Water closets or washdown urinals may require the Angle Stop to be set at only ONE TURN OPEN. For a SHORTER flush, turn the
Regulating Screw (061024A, item #9) left (counter-clockwise) and right (clockwise) for a LONGER flush (except -6, -48, -42, -19 and -05
models which are not field adjustable).
