Cartridge Installation 
 
 
 
 
Turn off water supplies. Remove bonnet nut 
(1) and test cap (2) from the body. If this is not 
a thin wall mounting, the entire plasterguard 
(3) may be removed. If screen 
(4)  is  in  place,  remove  before  installing 
cartridge. 
Rotate  valve  cartridge  (1)  so  the  words 
“HOTTER COLDER” (2) appear on the  top. 
Insert cartridge assembly into rough-in body. 
A light coating of plumbers grease applied to 
o-rings may aid in assembly. Make sure the 
key (3) on the cartridge is fully engaged with 
the slot in the brass body (4). 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
For back to back or reverse installations 
(hot on right and cold on left) insert the 
cartridge with the “hot side” on the right. 
If you are not making a reverse or back 
to back installation skip this step and 
continue with step 2C. 
 
Slide bonnet nut (1) over the cartridge 
and thread onto the body. Hand tighten 
securely.
