The thermostatic cartridge seldom fails and the possibility of blocked filters should be investigated be-
fore contemplating replacing it. Small particles of water borne debris may still find their way onto the filter
screens on the thermostatic cartridge. These should be cleaned and re-fitted.
To replace the thermostatic cartridge:
1. Prise out the index button.
2. Remove handle screw.
3. Pull off the temperature control handle.
4. To remove the temperature handle carrier (grey
plastic moulding), slide the black serrated lever
clockwise and pull off. This will expose the
thermostatic cartridge.
FOR LEVER HANDLE VERSIONS:
1. Unscrew dog point screw and pull
off temperature control handle.
2. Remove handle insert screw.
3. Pull off the handle insert.
GENERAL MAINTENANCE TIPS:
• Isolate both water supplies first.
• Drain down the pipe work & product as much as possible:
fully open flow handle & unscrew shower hose.
• Use the correct size tools.
• Expect some trapped water to escape from the mixer.
• Ensure parts are re-assembled in the correct ‘reverse’ sequence.
• Observe torque settings - where specified.
• Restore both water supplies.
• Check all joints for leaks upon completion.
