Step by step

1. Match the seat and identify the top-fix kit

Before opening protective packaging, compare the pan shape and the seat’s published dimensions and adjustment range. Check length, width, fixing-hole spacing and clearance behind the hinges rather than assuming that every oval seat fits. Confirm the leaflet number and inventory its parts. This article selects the top-fix rubber-plug route; put the alternative bottom-fix washers and nuts aside. Missing or mismatched parts require the correct replacement kit, not improvised hardware.

2. Remove the old seat and prepare a dry surface

Remove the existing seat using its own release and fixing instructions, supporting it so it cannot strike the ceramic. Stop rather than cutting or forcing seized concealed fittings. Clean around the mounting holes, remove loose dirt and dry the surface thoroughly. Place temporary cling film over the bowl opening to catch dropped parts, and keep tools on the separate tray. Do not flush while the temporary cover is in place.

3. Check the outline and backward clearance before peeling

Keep the new seat’s hygiene film on while checking its position over the pan. Align the front edge and support the rear as a pivot to raise it carefully. Both the ring and lid need the backward resting clearance required by the leaflet; a position that allows only upright vertical resting is unsuitable. Stop if the shape, support or rear clearance fails. Remove the hygiene film only after these checks succeed.

4. Start the supplied top fixings loosely

Remove the bracket support covers and, only when ready to fit, peel the adhesive protective films. Insert the supplied rubber plugs into the compatible mounting holes and assemble the brackets and bolts in the leaflet’s top-fix order. Leave adjustment possible and avoid pressing the adhesive pads onto the pan yet. Do not mix the bottom-fix hardware into this assembly, enlarge the holes or use a powered driver to overcome resistance.

5. Use the correct spacer holes and align symmetrically

Fit the supplied spacer across the two hinge posts using its inner holes for this selected TS074R06 route. Rest the seat on the posts and spacer, then adjust both brackets until the seat sits evenly over the pan and the brackets are symmetrical. Lift the seat off if needed to reposition the brackets without sticking the pads prematurely. Recheck the front outline and rear movement before committing the adhesive position.

6. Set the adhesive position and tighten carefully

With the final alignment confirmed, press both brackets firmly against the pan for the leaflet’s specified twenty seconds. Lift the seat away carefully without shifting the brackets. Use the supplied hex key to secure the top-fix bolts, stopping short of overtightening. There is no universal extra-turn or torque value to add here. If a fixing spins, the bracket moves or ceramic sounds or damage raise concern, stop and consult the supplier.

7. Remove the spacer and engage the seat

Remove the temporary spacer, place the decorative caps over the secured brackets and lower the seat onto both posts. Listen for the engagement click described in the instructions. Check that both sides have engaged rather than accepting one locked hinge and one raised hinge. Locate the actual quick-release button, which may be at the front or back of the hinge barrel, and follow the model’s removal and refitting procedure without forcing it.

8. Check operation and remove the temporary bowl cover

Test the ring and lid gently through their intended movement and allow any soft-close action to finish on its own. Confirm even support on the pan and no sideways movement during ordinary hand checks. If anything shifts or binds, stop using the seat and correct it according to the kit instructions. Remove the temporary bowl film and loose packaging before use, clean up and wash your hands. Keep the leaflet for future release, cleaning and fixing checks.

Watch the method
