The air intake vent must be kept clear. It must not be covered.
Because the heat-pump dryer operates with a closed air circuit, sep-
arate exhaust ducting is not required.
The warm air expelled from the machine as a result of cooling down
the heat-exchanger warms the room air. It is essential to ensure the
room has adequate ventilation, e.g. by providing ventilation openings
that cannot be closed whilst the machine is in use. Insufficient ventil-
ation in the room increases the time required for drying, which in turn
will increase the amount of energy required for the drying process.
The ventilation openings must, on no account, be closed or
blocked by objects.
The heat pump in this tumble dryer operates according to the prin-
ciple of condensation. A separate, vented floor drain must be
provided at the installation site for condensate produced during the
drying process.
The condensate drainage point is located at the back of the heat-
pump dryer. Condensate can be fed via a downwards pointing pipe
to the floor drain. It must be ensured that condensate cannot flow
back into the dryer.
