Air Outlet Vent; Condensate Drainage - Miele PT 8257 WP Operating And Installation Instructions

Air outlet vent

Because the heat-pump dryer operates with a closed air circuit, separate 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. Insuffi-
cient ventilation in the room increases the time required for drying, which in turn will in-
crease the amount of energy required for the drying process.
The ventilation openings must, on no account, be closed or blocked by objects.

Condensate drainage

The heat-pump in this tumble dryer operates according to the principle of condensation.
A separate floor drain must be provided in the installation room 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 con-
densate cannot flow back into the machine.
