Turn off water supplies.
Remove cover (1),
bonnet nuts (2) and test caps (3) from the
rough-in body (4).
Place a bucket or small container over the front
of the valve body and slowly open the water
supplies to flush any debris from the supply
lines before installing the cartridge. Turn the
water supplies back off.
Insert adapter assembly (1) into rough-in
body (2). Make sure the adapter assembly
is correctly positioned and is pressed all
the way down inside rough-in body.
Rotate cartridge (1) so the words “HOT SIDE”
(2) appear on the left. Insert cartridge assembly
into rough-in body. Make sure the key (3) on the
valve cartridge is fully engaged with the slot in
the brass body (4). Insert bonnet nut (5) over
the cartridge and thread onto the body. Hand
tighten securely, slide o-ring (6) over bonnet
and cartridge. A light coating of plumbers
grease applied to o-rings may aid in assembly.
For the exceptions of back to back or reverse
installations (hot on right and cold on left) only:
Rotate valve cartridge (1) so “HOT SIDE” (2)
appears on the right.
Apply silicone lube to the three o-rings shown
above to make the cartridge easier to install and
remove from the rough-in body.
Install the cartridge making sure that the keys
are fully engaged with the slot in the rough-in
body (see step C).
Slide o-ring (3) and bonnet nut (4) over the
cartridge and thread onto the rough-in body.
Hand tighten securely.
