 The connection points are subject to water supply pressure.
Turn on the stopcock slowly and check for leaks. Correct the
position of the seal and screw thread if appropriate.
The use of rubber or plastic tubing as pressure connection piping
between the installation location interior and the machine is only
permitted 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
before 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 (hot - red stripes) for the hot water
connection.
The temperature of the water intake must not exceed 70 °C.
If there is no hot water supply at the installation location for the
washing machine, the connection hose must be connected to the
cold water supply. A Y-piece is required in this case. The cold water
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 (without a
separate cold water intake).
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.
