THERMOSTATIC CARTRIDGE REPLACEMENT
Use the following method to inspect or replace the thermostatic cartridge:
1. Observe the disassembling sequence, see section 14, steps 1 to 3.
2. Remove the temperature control handle (left side) as detailed in section 16, steps 1 to 3.
3. Using a 32mm spanner or socket, undo the large nut retaining the thermostatic cartridge.
The cartridge should now slide out of the mixer's bore. Note: the nut is captivated onto the cartridge
& will rotate freely.
4. If necessary, replace the cartridge with a new one. Alternatively, if the cartridge is functioning correctly,
clean it thoroughly & reuse it.
5. 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.
6. 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.
7. 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.
8. Reverse the sequence to refit the drive bush & handle. Check & adjust the 40°C position as shown
in section 9. Ensure correct alignment of the handle as detailed in section 16.
