The water inlet hose for cold water (blue stripes) is not intended to
be used with a hot-water connection.
To minimize energy consumption during operation with hot water,
the washing machine should be connected to a suitable hot water
ring circuit if present.
So-called "transmission lines" (single lines to hot water generators)
can result in cooling down of the water remaining in the pipes if not
in constant use. More electrical energy would be needed in order to
heat the suds.
Use the water inlet hose supplied (red stripes) for the hot water con-
nection.
The temperature of the warm water intake must not exceed 158 °F
(70 °C).
If there is no hot water supply at the installation location, the hot wa-
ter inlet hose must also be connected to the cold water supply. An
additional Y-piece is required in this case. Cold water consumption of
the washing machine increases accordingly to account for the miss-
ing hot water inlet.
For functional and technical reasons it is not possible to operate
the machine exclusively with a hot water connection.
Even if a hot water connection is present, the washing machine
must be connected to a cold water inlet.
In the case of washing machines with a drain valve, a motorized valve
is used to drain the machine. A 2 ¾" angle connector can be used for
connecting the drain valve directly into the waste water system (with-
out a siphon) or into a floor drain (on-site gully with odor trap).
Thanks to an improved closing mechanism and a larger cross-sec-
tion, even the coarsest of soil does not leave any deposits or debris
behind which could result in blockages. The drain valve can also be
operated manually to allow the suds container to be emptied in the
event of a power failure.
A vented drainage system is vital for unimpeded drainage.
If several machines are connected to a single drain pipe, this
should be sufficiently large to allow all machines to drain simultane-
ously.
If the slope for drainage is extremely steep, the piping must be
vented to prevent formation of a vacuum in the machine's drainage
system.
Slow or obstructed drainage or a backup of water in the drum as a re-
sult of undersized pipework can result in faults occurring during pro-
gram sequences, which will result in fault messages appearing in the
machine display.
