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.

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.

1. DTV+ System Layout
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.
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.

NOTICE: Do not install the valve under a whirlpool surround or any location where the temperature may exceed 104°F (40°C).
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.
