1. Run well supported 3/4" hot and cold copper supply
lines for maximum flow.
2. Determine the ideal location of the valve, based on
user preferences. Install blocking to properly secure
the valve body.
3. Verify the supplies and outlet are secure and level.
The inlets must have a spread of 11-1/2"MIN to 11-
3/4"MAX. The outlet must be 5-7/8"MIN to 6" MAX
vertically from the inlets and centered horizontally
between the two inlets. Make sure the hot supply is
on the left and the cold supply is on the right. Cap
off supplies and outlet and check for leaks.
4. Cut the copper lines so they extend 15/16" from the
finished wall.

5. Unthread and remove the compression nuts and
compression rings, along with escutcheons and o-
rings from each elbow.
6. Slide the o-ring, escutcheon, compression nut and
compression ring over each connection tube,
making sure the threading on the compression nut is
facing outwards.
7. Loosen the knurled collars and thread the elbows
into the valve body until they stop, then un-thread
enough so that they align with the supply tubes and
outlet tube (MAXIMUM 3 ROTATIONS). Note that
the elbow seal is created by internal o-rings and
NOT by fully tightening the elbow.
8. Position the valve body assembly onto the supplies
and outlet until they are fully seated into the elbow
and then hand tighten the compression nuts. Slide
the escutcheon back towards the wall; and if the gap
is too large, as to where the escutcheon slides off
the compression nut, cut the supply and outlet tubes
accordingly.
9. With the valve level and up against the wall, mark
the 4 mounting hole locations through the holes that
are on the back plate of the valve body.
10. Loosen the compression nuts and remove the valve
body.
11. Drill the wall for the 4 wall anchors provided and
install them.
12. Re-install the valve onto the supply and outlet tubes,
then , using a wrench, tighten the compression nuts
fully. Tighten the knurled collars so that they are
tight against the side of the valve body. Make sure
the escutcheons are against the wall, with the o-ring
behind it.
13. Install the screws, through the valve body and into
the wall anchors to fully secure the assembly.
