Dispose of the dryer properly.
Energy-saving tips
■Spin the laundry before drying.
The drier the laundry, the shorter
the drying time will be, thus
consuming less energy.
■Load the dryer with the maximum
load.
Note: Do not exceed the maximum
load for the programs, as this
prolongs the drying time
and increases energy consumption.
■Ventilate the room and keep the air
inlet on the dryer free to ensure air
exchange.
■Clean the fluff filter after each drying
cycle. If the fluff filter is dirty,
the drying time is prolonged
and energy consumption is
increased.
■Energy saving mode: If the dryer is
not operated for a prolonged period,
it automatically switches off before
the program starts and when
the program has ended to save
energy. The display panel
and indicator lamps go off after
a few minutes and the Start button
flashes. To activate the lighting,
press any button, open or close
the dryer door or turn the program
selector.
)Dispose of packaging in an
environmentally-responsible
manner.

Changing the condensation
drain
Notes
■The condensation from the dryer can
either be discharged into the
condensation container or drained
off via a connection to the waste-
water system. By default, the
condensation from the dryer is
discharged into the condensation
container.
■If the condensation drain is installed,
residual water remains in the
condensation container due to the
dryer's self-cleaning function.
Proceed as follows to change the
condensation drain:
1. Remove the accessories from the
dryer drum.
2. When the dryer is delivered from the
factory, the hose for discharging the
condensation into the condensation
container is fastened to the
connecting piece.
3. Disconnect the hose from the
connecting piece and put it in the
"parked" position.
4. Take the drain hose from the
accessories and secure it to the free
connecting piece.
