If necessary, replace the cartridge with a new one. Alternatively, if the cartridge is functioning correctly,
clean it thoroughly & reuse it.

When fitting the cartridge into the bore, ensure the lug on the cartidge is orientated into the cut out in
the mixer’s bore, as illustration above.

Make sure the marking on the spline of the cartridge spindle is aligned with the edge of the „stop“ as
illustration above. Correct the alignment if necessary.

With the cartridge located back in the mixer bore, screw the cartridge nut into the mixer body by
hand & then tighten with a spanner or socket. Do not exceed 5 Nm torque.

underside, the left port should be closed as illustrated. Maintain this orientation of the diverter & slide
it into the mixer body. Note: the two locator pins on the front face of the diverter cartridge are different
sizes to prevent incorrect installation. Ensure these pins are correctly located into the plastic moulding
inside the mixer body.
