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.
