BEFORE YOU BEGIN
All information is based on the latest product information available at the time of publication. Kohler Co. reserves
the right to make changes in product characteristics, packaging, or availability at any time without notice.
Please leave these instructions for the consumer. They contain important information.
NOTES:
1. Risk of electric shock. Connect only to circuits protected by a Ground-Fault Circuit-Interrupte (GFCI) or
Residual Current Device (RCD). Grounding is required.The unit should be installed and grounded by a qualified
service representative.
2. Risk of electric shock. A licensed electricia should route all electrical wiring.
3. Risk of electric shock. Disconnect power before servicing.
4. Risk of injury or property damage. Please read all instructions thoroughly and determine all required compo-
nents along with their installation locations before beginning installation.
5. 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.
6. Do not apply petroleum-based lubricants to the valve components. Doing so will damage valve components.
7. Do not use oil-based, non-setting compounds, such as plumbers putty, on the threaded connections.
8. Observe all plumbing, electrical and building codes.
9. Make sure both hot and cold supply pipes are flushed thoroughly prior to connection to the Digital Mixer Valve.
10. If possible, install valve prior to installing the interface(s). When installing electrical outlet, please install an
on/off switch in a suitable position for easy operation during network connection and troubleshooting.
11. Do not plug or unplug cables on valve when the valve is power-on, which may damage the product.

INSTALLATION
Preparation
NOTES: Make sure both hot and cold supply pipes
are flushed thoroughly prior to connection to the
Digital Mixer Valve.
If possible, install electrical outlet before installing the
valve. Please turn off the electrical and water supplies
before installation. Always keep the valve and outlet
dry. Allow for enough slack in the cables for drip
loops.
Remote Control can be installed outside showering
enclosure, while the Dual Shower Interface is inside
the showering enclosure. Determine all required
components along with their installation locations
before beginning installation. NOTES: The valve can
not be connected to two interfaces at the same time.
When routing pipes, keep in mind each valve outlet
must correspond to the appropriate showering compo-
nent for the preprogrammed or custom showering
experiences to function properly. Please prepare
cable tubes before routing cables as the dimension.
NOTES: The showerhead fill supply line must be
routed from outlet 1, and the handshower is from
outlet 2. Port A is for the dongle(not provided, 23777T)
connection, port B is for joining cable.
Installation Steps
□ Mark the fixing holes in required positions,drill three
holes on mounting surface according to the rough-in
dimensions and diameter of the anchors(2).
□ Press anchors into the holes, install and secure
Digital Mixer Valve in position with fixing screws(1).
NOTES: Install the offset foot(3) if needed.
□ Install nut A, the ring and nut B onto inlet/outlet.
Hand-tighten nut A and nut B. Hold nut A with a
wrench, meanwhile tighten nut B with another wrench.
NOTES: The connector kit must be pushed into the
end towards valve direction，tighten it firmly.
□ Connect hot and cold water supply pipes to Digital
Mixer Valve.
□ Route pipes from valve outlet to the installation
locations of showerhead and wall-mount connection.
□ Route cables from valve to the Dual Shower UI and
Remote Control installation locations.
Install the Valve
NOTES: The Digital Mixer Valve may be installed in a
loft space or in a convenient space provided enough
room for maintenance. Failure to do so may result in
an inability to carry out any maintenance.
Installation Direction of the Valve
Do not mount the valve with the inlets located at the
top. Do not mount the valve with the inlets or cable
sockets pointing up.Vertical and horizontal mounting
options are shown as the figure.

CARE AND MAINTENANCE
Clean the Inlet Screen
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 inlets.
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.

Any debris or mineral build-up may cause distorted flow
stream or reduce the flow rate. To remove the debris or
mineral build-up, run water through the handshower, firmly
press or rub your finger back and forth across the rubber
nozzles.
Remove and clean the screen washer.
