IMPORTANT INSTRUCTIONS
WARNING: When using electrical products, basic
precautions should always be followed, including the
following:
DANGER: Risk of electrocution. Disconnect the electricity
to the working area at the main breaker panel before
performing the installation steps for hardwiring.
DANGER: Risk of electric shock. Connect only to circuits
protected by a Ground-Fault Circuit-Interrupter (GFCI).
Grounding is required. The unit should be installed and
grounded by a qualified service representative.
WARNING: Risk of electric shock. A licensed electrician
should route all electrical wiring.
WARNING: Risk of electric shock. Disconnect power before
servicing.
WARNING: Risk of injury or property damage. Please read
all instructions thoroughly before beginning installation.
NOTICE: Follow all plumbing, electrical, and building codes.
NOTICE: Provide unrestricted service access to the Power Data
Supply (PDS). This access must be located immediately next to the
PDS. Refer to the roughing-in information.

Important Information
NOTICE: Choose an automatic compensating valve with the
appropriate minimum flow rate to assure your valve will provide
safety at the lowest flow rates.
•For a showerhead rated at 2.5 gal/min (9.5 l/min) maximum, use
with an automatic compensating valve rated at 2.0 gal/min (7.6
l/min) or less.
CAUTION: Risk of personal injury. If the rain panel is not
securely held in place during installation, the product may
fall causing personal injury. Get help when installing the light
panel assembly and waterways.
Observe all local plumbing, building, and electrical codes.
Your model may differ in appearance, the instructions still apply.
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’ (7.62 m) of the rain panel.
Inspect the supply piping for damage. Replace as necessary.
The PDS is intended for hardwire installation. Make sure
electrical power can be provided to a service closet or 2x6 stud
framing with access panel, not more than 2’ (0.61 m) from the
intended PDS mounting location.
The installation must have a Class A Ground-Fault
Circuit-Interrupter (GFCI). The GFCI protects against
line-to-ground shock hazard. Use a 100 VAC - 240 VAC, 50 Hz -
60 Hz supply.
To reduce the risk of electric shock, locate the PDS and overhead
rain panel within proximity to each other to allow for each cable
to have a drip loop.

A 30’ (9.14 m) power cable is supplied for connecting the
overhead rain panel to the PDS. A 30’ (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.
Route the chroma power cable from the rain panel installation
location to the PDS installation location.
Route the chroma data cable from the PDS installation location to
the media module or steam adapter installation location.

2. Install the Supply Piping – Single Supply
Route the water supply lines.
Use the provided soldering template to construct a pressure
balancing loop.
Position tees in the loop over each of the four raised locations on
the template.
Solder the assembly while it is attached to the template.
Remove the pressure balancing loop from the 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.

3. Install the Supply Piping – Multiple Supplies
Route the water supply lines.
Use the provided soldering template to construct the pressure
balancing loops.
Position tees in the loops over each of the four raised locations on
the template.
Solder the assembly while it is attached to the template.
IMPORTANT! To ensure proper alignment of the tees with the
product, the two pressure balancing loops must be rigidly connected
to each other while on the soldering template.
While still on the soldering template, rigidly connect the two
pressure balancing loops to each other.
Remove the pressure balancing loop assembly from the template.
Connect the pressure balancing loops to the water supplies.
Do not strap the pipes.
Temporarily install a nipple to each tee. Do not use any sealant.

4. Install the Support Framing
WARNING: Risk of injury or property damage.
Template/cradle must be properly secured to support the
weight of the rain panel. Secure the cradle to the framing
using a minimum of six #8 x 1-1/2″long drywall screws.
If installing the rain panel to a finished ceiling, remove drywall
from the installation location.
IMPORTANT! The soldering template must be secured to structural
framing.
Attach a mounting surface to structural framing of the ceiling
using #8 x 1-1/2″long drywall screws.
Construct the support framing using 2x4 studs as shown in the
illustration above. The face of each 2x4 should be installed flush
with the face of the ceiling joists.
Position the soldering template/cradle under the pressure
balancing loop(s), as illustrated. Attach the cradle to the support
framing.
Do not strap the pipes.
