CAUTION: Risk of personal injury. If the rain panel is not securely held in place during
installation, the product may fall. Get help installing the light panel assembly and waterways.

IMPORTANT! The following steps require two people.

Insert an escutcheon into one of the four openings in the light panel. Orient the double ribs of the
escutcheon toward the center of the panel.

While another person holds the light panel in the rough opening, thread an adapter into the pipe
nipple.

While the other person continues to hold the panel, install the three remaining escutcheons and
adapters to hang the fixture.

Release the panel after the four adapters are installed. The panel will not be tight to the ceiling at
this time.

IMPORTANT! Secure the adapters sufficiently to create a water-tight seal for the pipe threads.

Secure each adapter using the 11 mm bit (provided) with the 11 mm or 7/16″ socket extension, and
socket wrench. Use masking tape to hold the bit in place to prevent it from falling off and causing
damage to your shower. The light panel should still sit loosely against the ceiling.

Install the waterway by aligning the notch in the waterway with the double ribs on the inside of the
leak shield.

Press the waterway into place over the adapter. Secure the waterway to the adapter with the screw
provided. Do not completely tighten at this time.

Repeat for the remaining waterways.
Tighten the screws evenly until the outer frame of the panel is against the ceiling, and the sealing

gasket is compressed.

IMPORTANT! If the light panel frame does not meet the ceiling within 1/32″ (1 mm), the pipe nipple is
too long. Check the rough depth. Try turning the threaded adapter further, or use a shorter pipe nipple.

DANGER: Risk of electrocution. Disconnect the electricity to the working area at the main breaker
panel before performing the installation steps for hardwiring.

The PDS is designed to fit within a service closet or 2x6 stud cavity with access panel. The PDS
must be within 25’ (7.62 m) of the lighted rain panel.

Install adequate bracing for mounting the PDS.
Route electrical wire to the service closet or 2x6 stud framing, within 24″ (610 mm) of the PDS.

Make sure the wire is in a position to reach the PDS where electrical connections can be made, and
allow enough wire to create a drip loop.

Position the PDS box within the closet or stud cavity to allow room for cover removal and
connecting the cables. If possible, connect the cables through the side holes rather than the cover
holes to ease cover removal for servicing.

Attach the PDS to structural framing or another secure surface using standard wood or drywall
screws (not supplied). Mounting boards may need to be installed between stud framing.

9. Connect the Cables

IMPORTANT! When possible, connect the cables through the side holes of the PDS rather than the cover
holes to ease cover removal for servicing.

NOTE: Make drip loops in all cables and cords.

Prepare cable ends for installation into the PDS by unthreading the strain relief cap and separating
the rubber stopper from the threaded body. This will prevent the cables from twisting while the
strain relief is threaded into the box.

Insert the chroma power cable into a 1/2” NPT hole and install into the “RAIN PANEL” connector
until it snaps together.

Insert the data cable into a 1/2” NPT hole and install into the “DATA IN” connector until it snaps
together.

Secure the cables and the electrical wire to the PDS using the watertight strain relief fittings. Thread
the fitting into the box, then slide the rubber stopper into the fitting. Tighten the cap to create a seal.

IMPORTANT! Verify all unused holes of the PDS box have plugs installed.

Verify all wires are tucked into the PDS housing and will not be pinched when securing the access
cover.

Reinstall the access cover. Do not overtighten.

Complete the Installation

If not already installed, install the K-99695 system controller according to the instructions packed
