IMPORTANT INSTRUCTIONS

WARNING: When using electrical products, basic precautions should always be followed, including the following:

WARNING: Risk of electric shock. A qualiﬁed electrician should route all electrical wiring.

WARNING: Risk of electric shock. Disconnect power before servicing.

WARNING: Unauthorized modiﬁcation may cause poor performance of the valve. Do not make

modiﬁcations to the valve as this could adversely affect the performance of the valve and void the warranty. Kohler Co. shall not be liable under its warranty or otherwise for personal injury or damage caused by any such unauthorized modiﬁcation.

DANGER: Risk of injury or property damage. If the power cord gets damaged, it must be replaced by the manufacturer, its authorized service agent or qualiﬁed personnel to avoid danger.

WARNING: Risk of injury. This device is not intended for use by persons (including children) with different or reduced physical, sensory, or mental abilities, or who lack experience or knowledge, unless they are under the supervision of or receive training for the use of the device by a person responsible for their safety. Children should be under supervision to ensure that they do not use devices as toys.

WARNING: Risk of injury or property damage. Please read all instructions thoroughly before beginning installation.

NOTICE: Follow all plumbing, electrical, and building codes.

NOTICE: Some electrical codes require a circuit protected by a Ground-Fault Circuit-Interrupter (GFCI)*.

NOTICE: For K-557-K1: If a GFCI outlet is required, connect only one valve per outlet.

NOTICE: Provide unrestricted service access to the valve.

NOTICE: The valve manufacturer’s minimum ﬂow rate is 1.6 gal/min (6 l/min).

*Outside North America, this device may be known as a Residual Current Device (RCD). ___________________________________________________________________________________________________

Operation with DTV+

To connect the valve to the DTV+ system, the K-99695 system controller is required.

The provided data cable is used to connect the valve to the system controller. Refer to the ″DTV+ System Layout″ section in this guide.

Before Operating the System For the First Time:

Download and install the latest software for connected components. This may take an hour or more to complete based on system conﬁguration and internet connection speed. Do not disconnect the power from

any components during software download and installation.

Before You Begin

NOTICE: Do not install the valve under a whirlpool surround or any location where the temperature may exceed 104°F (40°C). The valve and its integrated power supply is rated to operate in temperatures up to 104°F (40°C).

NOTICE: Do not apply excessive heat near the valve or apply ﬂux or acids directly onto the valve. This valve contains plastic and rubber components which will melt if heat is directly applied.

NOTICE: Do not apply petroleum-based lubricants to the valve components. Doing so will damage the valve components.

NOTICE: Do not use oil-based, non-setting compounds, such as plumbers putty, on the threaded connections.

Kohler Co. 3 1240338-2-A

Before You Begin (cont.)

NOTICE: Do not remove the check valves from the inlets as this can damage the product.

NOTICE: If the valve will be used for a bath/shower application, the bath ﬁll supply line must be routed

from the #1 outlet port.

Read these instructions and determine the locations of all required components before beginning installation. For shower conﬁguration options, refer to the guide on the K-99695 controller product page at www.us.kohler.com.

If possible, ﬂush all piping thoroughly before installing the valve. If the pipes are ﬂushed after the valve is installed, clean the inlet screens before using the system.

A qualiﬁed electrician should install a 120 V electrical outlet, within the stud framing, in close proximity to the valve. A GFCI outlet may be required in certain applications.

If possible, install the electrical outlet prior to installing the valve.

Multiple Valve Applications

Showering conﬁgurations using large water volumes require supply piping and drain systems that will sufficiently accommodate the actual total ﬂow rate at any one time.

Hot water generation: Use a water heating system capable of handling large ﬂow rates. Tankless (on-demand) water heaters and recirculating pumps may not be adequate for your showering conﬁguration.

The K-99695 system controller powers the interface(s) and controls the digital valve(s) and other system components. The controller is required to conﬁgure the valve(s).

NOTICE: If the valve will be used for a bath/shower application, the bath ﬁll supply line must be routed from the #1 outlet port.

NOTICE: Custom shower conﬁgurations may not allow certain features to be enabled. For shower conﬁguration options, refer to the guide on the K-99695 controller product page at www.us.kohler.com.

Determine the locations of all required components, including shower ﬁttings.

A data cable is provided to connect the valve to the controller. If the valve is not within 25’ (7.6 m) of the controller, obtain a longer telephone-style cable or add an extension cable.

When routing piping, make sure each shower ﬁtting will connect to the appropriate valve outlet for your conﬁguration.

NOTE: Horizontal installation within a stud cavity is shown. The valve can also be mounted vertically or mounted to a horizontal surface. Refer to the ″Mounting Conﬁgurations″ section.

K-528-K1: This product is designed to ﬁt within a minimum 14-1/2″ (368 mm) 2x4 stud cavity. K-557-K1: This product will not ﬁt within a standard stud cavity. Construct a minimum 18″ (457

mm) wide 2x4 stud cavity. Install adequate bracing for mounting the valve. Notch the bracing as needed to accommodate the

inlets and outlets.

Install a 120 V electrical outlet within the stud framing, in close proximity to the valve. Locate the outlet above the valve. A GFCI outlet may be required in some applications.

NOTICE: Do not apply excessive heat near the valve or apply ﬂux or acids directly onto the valve. This valve contains plastic and rubber components which will melt if heat is directly applied.

IMPORTANT! If your water supply has high amounts of particulates, install wye strainers in the supply lines.

Route the water supply lines. Use unions to install removable pipe segments to the valve inlets to allow access for periodic cleaning of the inlet screens.

Install shut-off valves and water hammer arrestors in the supply lines prior to the valve. Hold the valve up to the installation location. Verify ﬁt and mark the hole locations. Pre-drill the holes. Secure the valve with the washers and screws. Do not overtighten.

IMPORTANT! Make sure each shower ﬁtting is connected to the appropriate valve outlet for your shower conﬁguration. For shower conﬁguration options, refer to the guide on the K-99695 controller product page at www.us.kohler.com.

Route the piping from the valve outlets to the appropriate shower ﬁtting. Connect the hot and cold supply lines to the appropriate valve inlets. Hot is red and marked with

″HOT,″ cold is blue and marked with ″COLD.″ Secure all piping to the framing.

Test for Leaks

Turn on the water supply to the valve. Connect the jumper to the valve. Verify there is power to the 120 V electrical outlet, then plug the power cord into the outlet. Wait 10 seconds for the valve to initialize; the outlets will activate. Check all connections for leaks. Disconnect the power, then remove the jumper.

Connect the Cables

NOTE: Make drip loops in all cables and cords.

Install the K-99695 system controller according to the instructions packed with the product. Route the data cable in the wall between the controller and valve installation location. Attach a split boot to the data cable, toward the end that will connect to the valve. Connect the cable to the valve. Press the boot over the connection in the valve socket. Insert a solid boot into the unused socket.

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

Disconnect the power and turn off the water supply. Unthread the plastic nuts from the hot and cold inlets. Remove the copper tubes. The O-ring and screen may be attached to the end of the tube. If the screen remains in the check valve, use a small bladed screwdriver to gently pull the check

valve from the valve inlet. Remove the screens from the copper tubes or check valves. Clean the screens to remove any dirt or debris. Rinse or replace the check valves and screens. Reassemble the inlet connections.
