Trevi Traditional Therm - Built-In Shower Valve Mark 1

Hi, I understand I have the Mark 1 version of this shower valve, which doesn't have the temperature adjustment carrier. Do you have an instruction manual for setting up the thermostatic valve which doesn't have the carrier? With reference to your diagram, Part 19 is fitted but there is no Part 20. One other thing. If the shower is shut-off using the normal on/off valve then would I be able to remove the thermostatic valve to check the screens without having to drain the main distribution system (gravity fed)? regards Jonathan

Not sure I understand.

Below is an exploded view of the earlier valve.

And the later valve

I think you may be pushed to get an instruction manual for the pre 97 valve

Not necessary to turn the water off to remove the thermostatic cartridge however for safety I would.
