the connections required for this (e.g. angle valve) will already have
this safety feature. Make sure that a non-return valve is fitted in the
plumbing.
When using a separate non-return valve, observe the following se-
quence:
1. Attach the non-return valve to the water connection.
2. Attach the water inlet hose to the non-return valve.
 Health risk and risk of damage due to contaminated incoming
water.
The quality of the incoming water must correspond to the drinking
water specification of the country in which the washing machine is
being operated.
Always connect the washing machine to the mains water supply.
For the cold water connection, one stopcock each with
a ¾" external thread is required.
The water inlet hose for cold water (blue stripes) is not intended to
be used with a hot water connection.
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.
Use the inlet hose supplied (red stripes) for the hot water connection.
The temperature of the hot water intake must not exceed 60 °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 connection. A Y-piece is required in this case. The cold
water consumption of the washing machine 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.
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 connec-
ted 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).
