1. If the volume control handle is in the off
position it should not be necessary to isolate
the valve from the supply for this operation.
2. Remove handles (7). (see pages 10/11 for
details)
3. Remove the front cover plate (1) by prising
forward using the small slots at the sides of
the front cover plate.
4. Remove the two cover plate screws (3) and
pull off the back cover plate (2).
5. Remove shroud by pulling froward (9)
6. Remove the temperature adjustment carrier
(21) by rotating the black locking latch and
pulling forward.
7. Remove the rear temperature handle exten-
sion (20) by rotating the black locking latch
and pulling forward.
8. The thermostatic cartridge (19) can now be
removed by turning anticlockwise.
9. It is usually unnecessary to fit a new
thermostatic cartridge. Most problems
occur because debris from the pipe work
has blocked the cartridge filter screens.
10. The cylindrical filter screens can be removed
for cleaning by removing the o-rings from
the cartridge and sliding the screens off. Do
not attempt to refit the cartridge with the
filter screens missing. Any small particles of
grit in the water supply will cause the mech-
anism to jam. (Place all components which
have grease on them on a clean piece of
paper to avoid picking up grit)
11. Grease the cartridge o-rings with silicone
grease when they have been refitted.
12. If a replacement cartridge is being fitted, fit
it at this stage.
13. The valve is assembled in reverse order.
