Maintenance
Removing the Cartridge
1. Shut off the water supply to both inlets at the isolating valves.
Ensure the thermostatic valve has been successfully isolated.
See page 9 for correct procedure.
2. After removal of handle assemblies, wall plate, stop adaptor,
and stop ring, use a 2mm hex key to loosen the grubscrew in
the bottom threaded section, then unscrew the entire bottom
threaded thermostatic housing.
For more information see the installation manuals.
3. Carefully pull out the thermostatic cartridge.
4. Clean filters by rinsing them under running water to remove
any debris.
5. If there is limescale deposits then it is recommended to
immerse the cartridge for a few minutes in 50% white vinegar
+ 50% hot water, brush the filters gently and then rinse under
running water to clean all particles. If this is not effective, a
replacement cartridge should be fitted.
6. Before reassembling the cartridge, clean its housing with
a wet cloth and grease the ‘O’ rings using a suitable silicone
grease, insert the thermostatic cartridge.

Thermostatic cartridge
This thermostatic valve is fitted with a single filtering facility.
Filters are fitted on the thermostatic cartridge. Depending on
the water quality, filters may become dirty, causing reduced
flow and inefficient working of the valve. To clean the filters, you
must first remove the cartridge from the housing.
