Before You Begin
Observe all local plumbing, building, and electrical codes.
Read these instructions and determine all required components
along with their installation locations before beginning this
installation.
This product is designed for ceiling-mount installation only. Do
not install to a shower wall.
This manual covers vertical installation of the Power Data Supply
(PDS) in a service closet or 2x6 stud pocket. If the wall is
enclosed, an access panel must be provided for servicing.
The PDS may also be mounted under the floor joists. If mounting
under the floor, the unit must not be enclosed.
The PDS must be located within 25 ft (7.62 m) of the rain panel.
Inspect the supply piping for damage. Replace as necessary.
A licensed electrician should install a 15 A 120 V GFCI/RCD
electrical outlet within a service closet or 2x6 stud framing with
access panel, not more than 2 ft (0.61 m) from the intended
mounting location of the PDS.
The PDS may be hardwired. For optional hardwire installation of
the PDS, order Service Kit #1078031.
To reduce the risk of electric shock, locate the outlet, PDS, and
overhead rain panel within proximity to each other to allow for
each cable to have a drip loop.
Kohler Co. reserves the right to make revisions in the design of
products without notice, as specified in the Price Book.

Determine Components (cont.)
A 30 ft (9.14 m) power cable is supplied for connecting the
overhead rain panel to the PDS. A 30 ft (9.14 m) data cable is
supplied for connecting the PDS to the media module or steam
adapter.
Determine all required components along with their installation
locations before beginning the overhead rain panel installation.

2. Prepare the Site
The PDS is designed to fit within a service closet or 2x6 stud
cavity with access panel. The service closet or access panel must
be located less than 30 ft (9.14 m) from the overhead rain panel.
Recommended maximum distance is 25 ft (7.62 m).
If mounting boards are required, they should be positioned to
allow adequate surface area to attach the PDS via the existing
mounting holes on both ends of the PDS box.
Install a 120 V GFCI/RCD electrical outlet within the service
closet or 2x6 stud framing, within 24” (61 cm) of the PDS. Locate
the outlet in close proximity to the PDS to allow enough cable to
create a drip loop.
Note: For hardwire installations, order Service Kit #1078031.

3. Install the Power Data Supply
Orient the PDS box within the service closet or access panel to
allow room for cover removal and connecting the cables. If
possible, connect the cables through the side holes rather than
those on the cover to avoid complicated cover removal for
servicing.
If installing the PDS within a 2x6 stud cavity, position it to the far
left of the cavity to allow room for connecting the cables to the
side holes.
Attach the PDS to structural framing or other secure surface using
standard wood or drywall screws (not supplied). Mounting
boards may need to be installed between stud framing.
Route the Chroma data cable from the PDS to the media module
or steam adapter.
Route the Chroma power cable from the PDS to the overhead rain
panel location.

4. Install the Supply Piping – Single Supply
Route the water supply lines.
Use the provided soldering template to construct a pressure
balancing loop; this will ensure proper alignment with the
product.
Assemble the pressure balancing loop with a tee positioned over
each of the four raised locations on the soldering template.
Solder the assembly while it is still attached to the soldering
template.
Remove the pressure balancing loop assembly from the soldering
template.
Connect the pressure balancing loop to the water supply.
Do not strap the pipes.
Temporarily install a nipple to each tee. Do not use any sealant.
