Connection should be made via a suitable isolator
which complies with local and national safety
regulations and which is easily accesible for
disconnecting the dryer from the electricity supply.
Provision must be made on site to switch off all poles.
Switches with a minimum all-pole contact gap greater
than 3 mm are suitable for isolating the dryer. These
include circuit breakers, fuses and relays (IEC/EN
60947).
If the dryer is disconnected from the electricity supply
ensure adequate measures are taken to ensure that it
cannot be reconnected to the electricity supply until
all work has been carried out.
After the dryer has been connected to the electricity
supply check the phase rotation of the compressor.

buzzing noise will be heard. Incorrect rotation of
the compressor will cause damage to the unit and
it must be shut down immediately.

The dryer may only be operated in a room where
sufficient cool, fresh air is available. If the ambient
temperature is constantly above 45 °C, the circulatory
system of the heat pump unit should be connected to
a fresh air supply and the exhaust air should be
extracted externally.

Condensate drain

The heat pump tumble dryer is a condenser dryer.
Condensate is drained separately via a drain in the
base.
The condensate drain C 30 mm is located at the rear
of the heat pump unit and can be connected to a
floor gully by means of a hose or pipe with a gradient.
,
After setting up and connecting the dryer and
heat pump unit, ensure that all outer casing parts
are correctly fitted back into position.
