11 / 104
General information
The customer does not need to dismantle the second water pipe that they have
made available for the unit. The second water connection on the unit makes use
of the additional water supply, which means that it is regularly flushed. The con-
nection hose from one of the two water taps (via optional connections) is placed
in the unit and directly connected. The second water connection operates the
hand shower.
