Drain Valve; Dispenser Pump Connections - Miele PWM 912 SD Plano De Instalación

Drain valve

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.
A motorised dump 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 gully
(with odour trap).
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 simultan-
eously.
The appropriate Miele installation set mat. no.: 05 238 090 is avail-
able to order from Miele 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
system.
Slow or obstructed drainage or a backup of water in the drum as a
result of undersized pipework can result in faults occurring during
programmes, which will result in fault messages appearing in the dis-
play.
 Risk of burning due to hot suds.
Outflowing suds can be as hot as 95 °C.
Avoid direct contact.

Dispenser pump connections

Up to 12 dispenser pumps can be connected to the washing ma-
chine.
