Tools and Materials

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 are 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 that 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, nonsetting compounds, such as plumbers putty, on the threaded connections.
• 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 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, close to the valve. A GFCI outlet may be required in certain applications.
• If possible, install the electrical outlet before 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.

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 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 that 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.

Mounting Configurations

NOTICE: Do not mount the valve with the inlets pointing up or positioned above the outlet ports. Doing so will damage this product.

• The two-port valve is shown above. The same vertical or horizontal mounting configurations apply for the three-port valve.

Prepare the Site

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) 2×4 stud cavity.
• K-557-K1: This product will not fit within a standard stud cavity. Construct a minimum 18″ (457 mm) wide 2×4 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, close to the valve. Locate the outlet above the valve. A GFCI outlet may be required in some applications.

Assemble the Adapters and Unions

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 that will melt if heat is directly applied.

• Disassemble the adapter. Ensure that all rubber and plastic components are removed.
• Slide the union nut onto the inlet/outlet tube.
• Solder the inlet/outlet tube to the union. Allow to cool completely.
• Assemble the union.
• Slide the adapter nut onto the inlet/outlet tube.
• Assemble the adapter lock onto the inlet/outet tube and slide the assembly into the adapter nut.
• Slide the O-ring onto the inlet/outlet tube.
• For inlet tubes only: Insert the screen into the end of the inlet tube.
• Reinstall the adapter assembly to the valve.
• Repeat for all inlet/outlet tubes as required.

Install the Valve

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 that 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 before the valve.
• Hold the valve up to the installation location. Verify fit and mark the hole locations.
• Predrill the holes.
• Secure the valve with the washers and screws. Do not overtighten.

IMPORTANT! Make sure that 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 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.

Installation Checkout

Test for Leaks

• Turn on the water supply to the valve.
• Connect the jumper to the valve.
• Verify that 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.

Configure the Valve (Requires an Installed Controller)
NOTE: Valves that have been recently installed, or have not been used for some time should be exercised before running tests or setting the maximum temperature.

• To configure valve setup, refer to the guide on the K-99695 controller product page at us.kohler.com.

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.

Clean the Inlet Screens

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 flat-blade 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.
