Maintenance
We advise that the below is carried out annually as failure to do so may
result in invalidation of warranty. Shut off the water supply to both hot
and cold inlets, before commencing any maintenance work below.
Thermostatic cartridge
To clean the filters, you must first
remove the cartridge from the
housing.
Removing the Cartridge
1. Shut off the water supply to
both inlets at the isolating valves.
Ensure the thermostatic valve has
been successfully isolated.
2. Using a suitably flat tool remove
the screw cover, unscrew and
remove the temperature handle
and pull off the metallic shroud
housing and spacer ring (g 1).
Remove the ceramic/chrome
temperature ring allowing access
to the valve (g 2).
3. Using pliers if required gently
remove temperature stop ring
(essential) (g 2).
4. Turn shower on to check
isolation, please ensure that your
body/hands are not under the flow
of water as there is a potential for
delivery of hot water.
5. Using a 32mm box spanner
unscrew and remove the valve
securing nut then carefully pull
out the thermostatic cartridge
(g 3).
Note: Ensure care is taken as a
small amount of residual water
may escape when removing the
cartridge.

then it is recommended to
immerse the cartridge for a few

replacement cartridge should be
fitted.

wet cloth and grease the O-rings
using a suitable silicone grease.

into the body aligning the slot in
the body with the grub screw

ring on the cartridge with the cold
step located at 7 o’clock (g 5).
