For the cold water connection one stopcock each with a
3/4" external thread is required. A connector (Y-piece) can be used if
required to connect 2 water inlet hoses with a ¾" screw thread to a
single stopcock with a 1" male thread.
To minimise 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 pipes" (single pipes to hot water generators)
can result in cooling down of the water remaining in the pipes if not
in constant use. More energy would then be consumed to heat the
liquid up again.
Use the inlet hose supplied (hot - red stripes) for the hot water
connection.
The temperature of the water intake must not exceed 70 °C.
If there is no hot water supply at the installation location for the
washing machine, the connection hose must be connected to the cold
water supply. A Y-piece is required in this case. The cold water
consumption increases accordingly to account for the missing hot
water intake.
For functional and technical reasons it is not possible to operate the
machine exclusively with a hot water connection (without a
separate cold water intake).
Even if a hot water connection is present, the washing machine
must be connected to a cold water intake.
Connection for hard water. For the hard water connection, the same
requirements apply as for the cold water connection.
If there is no hard water connection on site, the hose must be
connected to the cold water connection.
In the case of washing machines with a drain valve, a motorised valve
is used to drain the machine. An HT DN 70 angle connector can be
used for draining the machine directly into the waste water system
(without a siphon) or into an on-site floor drain (with odour trap).
Thanks to an improved closing mechanism and a larger cross-
section, even the coarsest of soiling 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 outage.
