Hot water
connection
PW 811 / PW 814 / PW 818
To minimise energy consumption during operation with hot water,
the washing machine should be connected to a 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 (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 nevertheless 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.
