Drain valve

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
suds up again.
The temperature of the water intake must not exceed 70 °C.
If there is no hot water supply at the installation location for the wash-
ing machine, the inlet hose for hot water must also be connected to
the cold water supply. A Y-piece is required in this case. The cold wa-
ter 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.
Even if a hot water connection is present, the washing machine
must be connected to a cold water intake.
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-sec-
tion, 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.
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 simultaneously.
The appropriate Miele installation kit (mat. no.: 05 238 090) is
available to order from the Miele Customer Service Department or
your Miele dealer for venting an HT DN 70 pipe.
If the slope for drainage is extremely steep, the piping must be ven-
ted to prevent formation of a vacuum in the machine's drainage sys-
tem.
Slow or obstructed drainage or a backup of water in the drum as a res-
ult of undersized pipework can result in faults occurring during pro-
grammes, which will result in fault messages appearing in the display.
 Outflowing suds can be as hot as 95 °C. Danger of burning!
Avoid direct contact.
