Bristan replacement cartidge

I have just received a SKBQ1503-973C replacement cartridge from yourselves can you advise what the two spare O rings are for and where should I apply the silicon grease
Asked 6 years ago by Allan
The "O" ring spares are for the cartridge and inside the shower body.

Grease should be applied on the "O" rings and threaded parts of the cartridge.
