Water connection

The flow pressure must amount to a minimum of 100 kPa and must
not exceed 1000 kPa. If the flow pressure is higher than 1000 kPa, a
pressure reducing valve must be used.
The machine must be connected to the water supply using the inlet
hoses provided.
 The connection points are subject to water supply pressure.
Turn on the stopcock slowly and check for leaks. Correct the posi-
tion of the seal and screw thread if appropriate.
Requirements for the UK, double check valves (supplied with the
washing machine) must be installed downstream of the service
valves before the connection of any supplied flexible hoses.
Without the installation of these double check valves the installa-
tion does not comply with the local regulations.
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.
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.
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 (red stripes) for the hot water connection.
The temperature of the water intake must not exceed 70 °C on ma-
chines with electric heating (EL).
