Installation Instructions
1. Insert the gasket into the groove on the concentric.
Making sure the gasket is in place, loosely mount
the concentrics and
fl
ange onto the control valve
body.
2. Mount the small riser to the control valve body
using thread sealant. Screw the add-on faucet to
the other end of the small riser, again using thread
sealant.
3. Mount control valve body to the backsplash by in-
serting the concentrics through the backsplash and
attaching slip joints. Attach elbows or supply lines
and tighten concentrics. Be sure to use pipe thread
sealant on all threads.
4. Mount the pipe to hose adapter to the enclosed
riser using thread sealant. Mount the other end of
the riser to the female outlet of the add-on body.
5. If no wall bracket is to be installed, proceed to Step
6, otherwise do the following:
a. Locate and drill a Ø7/16” hole in the wall directly
behind and about 3/4 the way up the riser pipe.
b. Loosely attach the front and back of the pipe
clamp onto the riser pipe.
c. Hold the wall bracket
fl
ange against the wall,
centered with the hole. Use the wall screws and
a screw driver to mount the
fl
ange to the wall.
d. Slide part, but not all, of the wall bracket rod non-
threaded end
fi
rst through the center hole of the
fl
ange and into the wall.
e. Align the rod with the pipe clamp and thread the
rod into the pipe clamp. Be sure the rod is level
by adjusting the pipe clamp position.
f. Once level,
fi
x the rod in place by tightening both
the set screw located in the
fl
ange and the pipe
clamp screws.
6. Slip the hose hook over the pipe to hose adapter.
Using thread sealant and a crescent wrench, thread
the SS hose into the pipe to hose adapter.
7. Install gooseneck spring by slipping SS hose
through the spring. Spring will
fi
t over adapter which
holds it in an upright position. Note: Be sure spring
is installed as shown. DO NOT INSTALL SHORT
