Usage Instructions
Before you start
30cm
1s
It is recommended to isolate the water supply
and flush the water from the cistern before
commencing installation.
Ensure that there is a 30cm clear area above
the cistern. Any obstructions such as shelves or
hanging objects could trigger the sensor if
positioned within this area.
Ensure that the cistern fittings are suitably arranged to allow for installation of the sensor flush kit by making the following
provisions:
Make sure that the overflow tube is positioned
on the opposite side of the cistern to the inlet
valve
Rotate the flush valve so that the REDUCED
flush paddle is on the same side as the overflow
tube.
Once the installation is complete, to activate a reduced flush, wave your hand over the sensor. To activate a full flush
hold your hand over the sensor for 1 second. When activated, a red light will show on the sensor.
Battery Replacement
When the battery level is
too low, the red indicator
light on the sensor will
blink for 10 seconds
when activated.
x10
The batteries must be
replaced using the
method shown below.
In the meantime, the full
flush function can be
activated using the
manual flush button.
BLUE PADDLE

To access the battery box, first disconnect the quick connector and remove the battery box from the cistern. Next, remove
the lid of the battery box making sure to squeeze the top washer to release the seal. You can now swap in new 4x1.5V AA
batteries and reconnect the battery box back up to the rest of the flush unit.

With the cistern lid on, measure the distance from the top face on the cistern to the flush valve paddles through the
cistern hole. Mark this distance on the flush button leg, using the underside of button’s rim as your datum point. Cut the
leg down to length at the marked point.

To form a seal in the
battery box, squeeze the
top washer until you no
longer hear any air leaving
the box.
If you are struggling to remove
the battery box lid, squeeze the
top washer to release the seal.
2 Choosing flush valve orientation
The pneumatic hook and overflow clamp will be attached to
the overflow tube of the flush valve so the flush valve must
be oriented to have the reduced flush on the OPPOSITE
side of the cistern to the inlet valve.
Secure the button in position by tightening the fixing nut and place the rubber bung onto the new cut end of the leg.
Ensure that the leg does not press the flush paddle down whilst in its rest position. Failure to do this may cause water to
constantly trickle into the WC pan.
6 Connecting up the Sensor
Once the flush valve is secured in position within the cistern,
ensure to check which side the hook needs to be attached to the
clamp so that it will sit above the reduced flush paddle. If the
hook orientation needs changing from the default, detach the
hook from the clamp body by unscrewing the fixing screw and
sliding the clamp body upwards. Switch the connection side by
using the grooves on the opposite side of the clamp body and
reconnect the two parts as shown above.
Insert the IR sensor into the slot in the bottom of the button until the locking clips engage and the sensor sits flush with the
top surface of the button. To complete the installation process, connect up the battery pack’s quick connector and place
the cistern lid back onto the cistern.

4.2 Connecting the Battery Box to the Control Box
Connect the battery box to the control box using one of the three options shown below, connecting fixings A, B or C of the
two parts together. The arrangement may need to be selected depending upon the room available within the cistern.

To detach the clear hose from
the hook, simply press in the
black connector and pull the
hose out, this may make
installation easier. To reattach
the hose simply slide it into the
connector and check it has
gripped in place.
If you are using a flush valve
with a slimline overflow tube,
you will need to slide the
overflow collar over the
telescopic overflow.
If you are using the overflow
collar make sure that the lip is
at the bottom when sliding on
to the overflow tube, as shown
above. If installed incorrectly
the clamp may work loose
from the overflow tube.

4.3 Connecting the Assembly to the Flush Valve
Using the male connecting hooks on the control box, the two components can now be connected to the flush valve
assembly. Alternatively, the battery box and control box can each be attached to the back of the cistern using the stainless
steel hanger. This can save room with the width or height of the overall product as the hanger allows for the boxes to be
positioned lower down within the cistern.
To install the clamp and hook,
slide the clamp over the
overflow tube.
hint
if using the collar for a slimline
overflow tube ensure the collar
is on the overflow tube before
attaching the clamp.
For optimum functionality,
ensure that the hook is resting
on top of the reduced flush
paddle.
Once set in position tighten the
screw to clamp the
components in place
important
the hook must not press down
the paddle when in its resting
state or the toilet may
constantly trickle.

If using a flush valve with a
telescopic overflow, check that
the overflow is locked in
position.

Once on the desired level wait 15
seconds and the sensor will exit the
adjustment mode and can be used as

You may need to add
the collar part to the
clamp.
Slide the collar onto the overflow tube, this should allow you to secure the
clamp around the wider overflow tube, such as the one found on TR9033.
Ensure to install the collar in the correct orientation (with the rim facing
downwards).
