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.
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: Provide unrestricted service access to the valve.
*Outside North America, this device may be known as a Residual Current Device (RCD).
___________________________________________________________________________________________________
Operation with DTV, DTV II, or DTV+
DTV: The valve is controlled from one or two user interfaces that connect directly to the valve.
DTV II: To connect the valve to the DTV II system, the K-638 media module is required.
DTV+: To connect one or two valves to the DTV+ system, the K-99695 system controller and
K-97172 data cable(s) are required.
Refer to the appropriate sections in this guide for your system configuration.

Roughing-In
Before You Begin
NOTICE: Do not install the valve or power supply under a whirlpool surround or any location where the
temperature may exceed 104°F (40°C). The power supply and valve 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 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 inlet
and outlet connections. Use sealant tape or liquid sealant.
NOTICE: Do not allow any outlet to flow more than 10 gal/min (37.9 l/min).
Read these instructions and determine the locations of all required components before beginning
installation.
When possible, install the valve before installing the other components.
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.

Before You Begin (cont.)
For optimum valve performance, the water heater should be set at 120°F (49°C). Hot water pressure
should be equal to or less than the cold water pressure.
This valve complies with UL1951, ASME A112.18.1, ASSE 1016, CSA B125, and CSA C222 No.
218.2-93. This valve is listed with ASSE, CSA, IAPMO/UPC, and UL.
Special Considerations for Large Showering Systems
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. Plan the System Layout
NOTE: The original DTV system is shown above. The interface cables do not connect directly to the valve
for DTV II and DTV+.
Determine the locations of all required components before beginning installation.
DTV (shown above): The primary interface, with the 8-pin cable, is located inside the showering
enclosure. An optional auxiliary interface, with the 4-pin cable, can be installed outside the
showering enclosure.
DTV II: Refer to the K-638 media module installation guide for system layout and required
components.
DTV+: Refer to the K-97172 data cable installation guide for system layout and required
components.
When routing piping, the numbers marked at each valve outlet must correspond to the appropriate
shower fitting for pre-programmed or custom showering experiences to function properly.
Custom showering experiences must be programmed into the interface prior to use. Refer to the
″Homeowners Guide″or ″Users guide″for the interface or controller for your system.

2. 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.
Vertical and horizontal mounting options are shown above.

3. Shower Configurations (DTV and DTV II)
NOTE: Pre-programmed shower configurations are shown; other options are possible. Configurations
other than the pre-programmed options will LIMIT the pre-programmed massage functions.
Massage functions that correspond with custom configurations can be programmed. Refer to the
″Digital Interface Homeowners Guide.″
The bodyspray to valve outlet ratio must be 1:1. All bodysprays must have equal flow rates;
unequal flow rates will cause the massage mode to shut down. See examples below:
Correct: Four bodysprays using four outlets, one per bodyspray (1:1). See the ″Envelop″configuration above.
Incorrect: Four bodysprays using three outlets; two bodysprays each installed to one valve outlet (1:1), and
the other two bodysprays installed to one valve outlet (2:1).

4. Custom Shower Configurations (DTV and DTV II)
Draw in the fittings for your custom shower.
Draw lines from the valve to each fitting. Be aware that:
•Outlet 1 should be the primary showerhead.
•The installer must determine the desired sequence for Single mode and plumb the ports to the
bodysprays accordingly.
•Custom mode will allow the user to select a different water outlet as the primary showerhead, but it
is not recommended.
•In Custom mode, the bodysprays will cycle up the solenoid bank regardless of which port is the
primary outlet.

5. Massage Cycling Configurations (DTV and DTV II)
NOTE: Primary outlets and any outlets designated as handshowers will not be included in the cycling
pattern. For installations that include both bodysprays and watertiles, the outlets designated as watertiles
will not cycle.
For massage cycling configurations for DTV+, refer to the guide found on the K-99695 controller
