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
Dual Shower
loops.
UI
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.

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.
