1.
Before carrying out any maintenance, ensure the water supplies
are isolated. Once isolated, turn the shower on to release
internal pressure.
If unsure contact a qualified tradesman.
2. Carefully remove the control handle cover cap by inserting a
suitable tool and levering out.
3. Using a 2.5mm hexagonal key, loosen the grub screw and remove
the control handle.
4. Unscrew the chrome cover ring.
5. Remove the large brass locking nut using a suitable spanner.
6. Prior to removing the cartridge, take note of its orientation as it
must be refitted the same way.
7. Using a suitable pair of grips pull the cartridge free from the valve
body. Rinse the cartridge under cold water to remove any debris
or limescale build up and grease the o-rings prior to re-fitting.
8. If necessary, replace the cartridge. A replacement cartridge can
be obtained by contacting customer service on 01959 560760.
9. Refit the cartridge into the valve body by lining up the two keyways
(located at the top left and right) and ensuring the positioning
mark (made in point 6) is aligned.
10. Refit the brass locking nut (taking care not to over-tighten), screw
on the chrome cover ring and place the control handle back into
position (lever at the 6 o'clock position).
11. Tighten the grub screw and fit the cover cap by pressing into
position.
12. Reinstate the water supply and ensure there are no leaks.
