Roughing-In – Deck-Mount
NOTE: If the bath filler is installed with the K-11343 drop-in bath,
ensure the distance between the centerline of each marked hole and
the flange contacting the bath deck is a maximum of 4″(102 mm).
To ensure that water will not drip outside of the bath, properly
position the faucet on the deck so the outlet will be located inside
the bath.

1. Assemble the Bath Filler
NOTE: The bath filler arms are NOT identical. The setscrew holes
on the long end of the arms should face each other.
Determine the left and right side arms.
Apply lubricant (provided) to the O-rings on the bath filler body.
Attach the short end of the arms to the bath filler body.
Usinga3mmhexwrench, secure each arm with a large setscrew.
Orient the handshower bracket with the large side of the taper
facing up.
NOTE: The handshower bracket should be assembled
perpendicular to the arm so the handshower hangs over the bath.
Slide the handshower bracket onto the arm for the hot water
supply.
Using a 5/16″hex wrench, tighten the small setscrews to secure
the bracket at the desired height.

2. Prepare the Site – Freestanding
Use the template provided with the riser tubes to mark the
location of the water supply lines from the bath drain.
Verify the distances between the centerlines of the holes according
to the dimensions above.
Drill the supply holes using a 1-5/8” drill bit or hole saw.
Insert the riser support through the holes. Secure to the subfloor
with eight wood screws (provided).
NOTE: To protect the riser support from debris when installing the
finished floor, position the thread protectors (provided) in the holes.
Install 1/2″water supply tubing. The total tubing height from the
finished floor with a 1/2″NPT male connector should be
21-9/16″(548 mm).
Install the finished floor.
Solder 1/2″NPT male copper connections to the water supply
lines. Verify the height to the top of these connections is 21-9/16″
(548 mm) from the finished floor.
Apply thread sealant to the male connection on each water
supply tube.

Thread a coupling assembly onto each water supply connection,
then tighten with a wrench. Verify the height to the top of the
coupling assemblies is 24-7/16″(621 mm) from the finished floor.
Install the plastic pipe plugs (provided) into the coupling
assemblies.
Turn on the water supply.
Check for leaks. Adjust as needed.
Turn off the water supply.
Remove and discard the pipe plugs.
Unthread the riser tubes out of the riser support and onto the
coupling assemblies until hand-tight.
Slide a gasket and escutcheon over each riser tube down to the
finished floor. Position the setscrew holes toward the bath.
Using a 5/16″hex wrench, secure each escutcheon with a small
setscrew.

6. Prepare the Site – Deck-Mount
NOTE: Provide an access panel under the bath deck for water
supply connections.

guide before proceeding.
Position the support plate on the bath deck where the water
supply tubing will be located. Trace the holes.
Verify that the location of the plate will allow the bath filler spout
to reach into the bath.
Verify the distance between the centerline of the marked holes is
5-15/16” (151 mm).
NOTE: If a hole saw will be used, drill outside the line of the
marked holes.
Drill the holes using a 1-9/16” drill bit or 1-1/2″hole saw.
Remove any debris after drilling.
Verify the drilled holes will accommodate the riser tubes. Adjust
the hole diameter slightly, if needed.
Secure the support plate to the unfinished bath deck with the
eight (provided) wood screws.
