The use of rubber or plastic tubing as pressure connection piping
between the installation location interior and the machine is only per-
mitted if:
- in conjunction with connection fittings, it can withstand a minimum
permanent pressure of 1500 kPa (15 bar),
- it is satisfactorily inspected during commissioning and
- after each use of the machine the water supply is reliably cut off be-
fore the rubber and plastic piping and put out of service or cut off
from the location interior.
Cold water con-
nection 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.
The water inlet hose for cold water (blue stripes) is not intended to
be used with a hot water connection.
Hot water con-
nection
To minimise energy consumption during operation with hot water,
the washing machine should be connected to a suitable hot water
ring circuit.
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 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 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.
Hard water con-
nection 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 con-
nected to the cold water connection.
Drain valve 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).
