Thank you for your question. To install the cartridge, first loosen the set screw on the handle (3/32" Allen) then slide off the handle and trim sleeve. Next, unscrew the Phillips head screw and the chrome sleeve. This will allow you pull off the extender. You can then unscrew the bonnet nut and remove the cartridge assembly. Replace the seats and springs with the small end of the spring inside the rubber seat and the larger end of the spring going into the valve first. Reinstall the parts in reverse order.
