Usage Instructions

Before you start

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 to avoid any obstructions triggering the sensor.

Cistern Fittings Arrangement

Make sure the overflow tube is positioned opposite the inlet valve. Rotate the flush valve so that the REDUCED flush paddle aligns with the overflow tube.

Installation Process

  1. Follow the fitting instructions provided in the manual.
  2. After installation, wave your hand over the sensor for a reduced flush and hold for 1 second for a full flush.
  3. A red light on the sensor indicates activation.

Battery Replacement

When the red indicator light blinks for 10 seconds, it indicates low battery level.

To replace batteries:

  1. Disconnect the quick connector and remove the battery box from the cistern.
  2. Remove the lid of the battery box, swap in new 4×1.5V AA batteries, and reconnect the box.

Fitting the Flush Button

  1. Measure and cut the flush button leg to align with the flush valve paddles.
  2. Secure the button in position by tightening the fixing nut and placing the rubber bung on the cut end.
  3. Ensure the leg does not press the flush paddle down to prevent constant water flow.

Before you start

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.

Fitting Instructions

Loading the batteries

\(18\)

  • Remove the battery holder from the battery box
  • Load 4×1.5V AA alkaline batteries (supplied separately) into the battery holder
  • To form a seal in the battery box, squeeze the top washer until you no longer hear any air leaving the box.

WARNINGS

  • Non-alkaline batteries will provide a much shorter battery life.
  • Do not mix batteries of different brands or mix old and new batteries.
  • Once connected to the power, the flush system will act once to show it is working.
  • If you are struggling to remove the battery box lid, squeeze the top washer to release the seal.

Choosing flush valve orientation

SCREWFIX-TR9031-Top-Entry-Close-Coupled-Sensor-Flush-Valve-Kit-FIG
\(19\)

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.

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.

Installing

Installing the Clamp and Pneumatic Hook

\(21\)

  • 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.

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.
important the hook must not press down the paddle when in its resting state or the toilet may constantly trickle.

Once set in position tighten the screw to clamp the components in place

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

Installing the Control Box and Battery Box

Attach the Battery Box Cradle

Insert the battery box into the cradle. This gives three options for assembly between the battery box and the control box as shown below.

Connecting the Battery Box to the Control Box

\(27\)

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.

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.

Fitting the Flush Button

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 the button’s rim as your datum point. Cut the leg down to length at the marked point.

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.

Connecting up the Sensor

\(17\)

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.

Usage Instructions

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.
  • 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

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 4×1.5V AA batteries and reconnect the battery box back up to the rest of the flush unit.
