must be provided on site. Switches with a minimum contact gap
greater than 3 mm are suitable disconnectors. These include circuit
breakers (MCB), fuses and contactors (VDE 0660) (IEC/EN 60947)
If the mains supply cannot be permanently disconnected, the isolation
device (including plug and socket) must be safeguarded against being
switched on either unintentionally or without authorisation.
The tumble dryer must not be connected to devices such as timers

which would switch it off automatically.
If local regulations require that a residual current device (RCD) is in-
stalled, a type B residual current device (sensitive to universal cur-
rent) must be used.
If local and national installation specifications require equipotential

bonding, good galvanic contact must be guaranteed. Equipotential
bonding must have an earth current rating > 10 mA.
 Loud noises and risk of damage due to incorrect phase connec-
tion on heat-pump dryers.
An incorrect phase position causes a lot of noise in tumble dryers
with heat pumps and can cause damage to the compressor.
When connecting a heat-pump dryer to the power connection, en-
sure the correct phase position according to the wiring diagram.
Peak-load negotiation
The heat-pump dyer can be connected to peak-load negotiation if this
is required. However, this is not essential, as the heat-pump dryer has
been designed for very low energy consumption.
Depending on the function, switching off the appliance externally
during the drying process when the heat-pump is in use can reduce
the service life of the appliance.
Please note that if it is connected to peak-load negotiation, the
heat-pump dryer must not be switched off.
Information on operating status is made available via the Miele peak-
load interface. Please note that the energy requirement of all appli-
ances that cannot be switched off in the energy management system
must be stored by the control system.
Air intake vent
The air supply for the cooler is drawn in through the air intake vent on
the front of the machine directly from the room in which the dryer is
installed.
There is a fluff filter in the dryer's air intake vent which must be de-
fluffed regularly by hand.
The air intake vent must always be kept clear. It must not be
covered.
