Rotate the valve cartridge (1) so the word “UP”
(2) appears on the top. The “H” is on the hot side
and the “C” is on the cold side. Add silicone lube
to the three o-rings (3) shown above to make
the cartridge easier to install and remove from
the valve body. Insert cartridge into valve body
as shown. Ensure the keys on the body are fully
engaged with the slots in the body (4). A light
coating of plumbers grease applied to o-rings may
aid in assembly.
