Roughing-In

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.

A licensed electrician should install a 120 V GFCI electrical outlet, within the stud framing, in close proximity to the electronic valve. The interface(s) is/are powered through the connection(s) with the valve.

Install the valve prior to installing the interface(s).

Kohler Co. reserves the right to make revisions in the design of faucets without notice, as speciﬁed in the Price Book.

1. Preparation

If not already installed, install the digital valve at this time according to the instructions packed with the product.

NOTE: The optional auxillary interface, with the 4-pin cable, is located outside the showering enclosure, while the primary interface, with the 8-pin cable, is located inside the showering enclosure.

Determine all required components along with their installation locations before beginning this installation.

Custom showering experiences other than the preprogrammed options must be programmed into the interface prior to use. Refer to the ″Digital Interface Homeowners Guide.″

NOTE: The 8-pin cable is used for the primary interface and the 4-pin for the auxillary interface.

Verify that both the primary and auxillary interface are located so the interface cable easily spans the distance between the valve and interface connection.

2. Prepare the Site

NOTE: Portrait interface shown, landscape interface also available.

NOTE: Allow for a 1/4″ (6 mm) overlap for the lip of the wall sleeve and a minimum clearance of 1/2″

(1.3 cm) around the back of the opening to enable the clips to fully engage.

Refer to the rough-in information. With a pencil, mark the cut lines onto the ﬁnished wall.

Carefully cut out the opening in the ﬁnished wall following the penciled guidelines.

For thin ﬁnished wall materials of less than 3/16″ (5 mm), shim around the back of the opening to provide adequate support for mounting the interface wall sleeve.

3. Install the Interface

CAUTION: Risk of product damage. Do not use power screwdrivers to install the interface.

NOTE: The clamp arms can be removed and turned upside down to allow installation to thicker walls.

Measure the ﬁnished wall thickness.

If appropriate, ﬂip the clip arms to accommodate thicker wall materials. Refer to the above illustration.

Secure the interface cable, from the valve, with a zip tie to the back of the wall sleeve allowing approximately 18″ (45.7 cm) of cable to hang free.

Insert the free end of the interface cable into the opening of the wall sleeve.

Tuck the clamp arms into the slots of the sleeve.

Apply a bead of silicone sealant into the groove around the backside of the sleeve lip.

Insert the sleeve into the cutout.

Turn the clamp arms so that they are perpendicular to the opening.

Handtighten the screws. Do not overtighten.

Wipe away any excess sealant from around the front of the sleeve. Use care not to get sealant on the outer surface of the sleeve.

Remove the cap from the interface cables.

Connect the interface to the interface cable.

Carefully feed the connection through the hole in the wall sleeve and into the wall cavity. A drip loop will automatically be formed in the cable.

5. Installation Checkout

Turn on the water supply to the valve.

Check all connections for leaks and make any adjustments as needed.

Turn on the main power supply. You should hear the valve power up and the power icon on the user interface will be lit with a green pulsing light.

If not already completed, refer to the ″Digital Interface Homeowners Guide″ to set up the interface.

Installation Checkout (cont.)

NOTE: For more information about using the user interface and its menus, refer to the user interface Homeowners Guide.

At the main menu of the interface select SHOWER > Options > All On. This will select all connected components and purge the air from the system.

Check for leaks and make any adjustments as needed.

Verify that the water ﬂow is sufficient for your showering needs.

6. Troubleshooting

CAUTION: Risk of personal injury. The valve may contain hot water; be careful when draining any residual water.

IMPORTANT! Turn off the power and water supply to the valve before performing any maintenance.

It is recommended that any valve maintenance should be performed by an authorized Kohler service representative.
