Measure out and mark the exact position based on the centre of the waste pipe. To install the wall brackets, stick them onto the ridged end of the threaded rod and roughly adjust and align it in accordance with the planned installation depth. Then secure with the clamps.
To mark the four attachment points, simply pull the frame upwards and check the height against the metre mark. The feet can be adjusted to increase the frame height to up to 200 mm, but should not be pulled out completely. Then secure the screw on one side, ensure the frame is level and tighten the second screw.
Make sure both feet have the same distance to the wall. Then mark the drill holes and please control that the wall brackets and the frame are parallel in height.
