Removing the cartridge
1. Turn off both water supplies to the shower valve.
. Remove the indice from the centre of the temperature control handle.
3. Remove the centre retaining screw.
4. Remove the temperature control handle assembly, by pulling it off.
5. Remove the circlip and then pull off the flow control handle.
6. Unscrew the two screws.
7. Remove retaining ring and slip ring.
8. Pull the cartridge forwards to remove it from the shower body.
WARNING
Tip: If the cartridge will not pull out of the body with ease,
replace the temperature control to provide more grip and pull
the cartridge out of the shower valve body.
If this is still to difficult replace the flow control and the circlip
and insert a broad flat headed screwdriver between the flow
control and the body and twist the screwdriver to ease the
flow handle away from the body. This should allow the
cartridge to be pulled out.

Replacing the Cartridge
1. Ensure that the ceramic disc valve is in the off / closed
position.
. Refit that cartridge back into the shower valve.
3. Fit the slip ring and retaining ring using the screws. If the
screw slots do not line up with the holes in the body,
remove the cartridge and turn it by the required amount and
refit until the screw holes line up.
5. Refit the flow control handle and circlip.
6. Refit the temperature handle/ centre Screw and indice.
9. Remove all of the seals from the body of the cartridge.

Replacing the Ceramic Disc (CD) Valve
1. Follow steps 1-8 as detailed in the Removing the Cartridge section.
. After the cartridge has been removed unscrew
the 18mm hexagonal nut on the back of the cartridge.
This will allow the CD valve to come out.
3. Replace the CD valve ensuring that the new valve is in the closed
position.
4. Replace the complete cartridge back into the valve body and replace the retaining ring, screws
and control assembly.
Temperature Adjustment
Temperature AdjustmentTemperature Adjustment
Temperature Adjustment
1. Turn on the water supplies and fully open the flow control, let the water run long enough to
ensure that the hot water supply is at its maximum temperature.
. Turn the temperature control anti-clockwise to its maximum position and check the outlet
temperature. This has been factory set at 41ºC at balanced supply pressures of 0.5 bar.
3. The maximum temperature can be adjusted to suit user preference. To adjust this, follow this
procedure:
4. Remove the temperature control handle assembly by removing the indice, unscrewing the retaining
screw and pulling the handle off the spindle.
5. Turn the spindle anti-clockwise to increase the temperature and clockwise to reduce it.
6. Refit the handle assembly so that the stop pin is at the maximum position then refit the screw and
indice.
