The air required for drying is taken from the room where the dryer is
installed.
Ensure sufficient room ventilation, e.g., by means of ventilation
openings that cannot be closed in the exterior wall.
- It must not be possible to seal off ventilation openings.
- The room ventilation is only working properly if no low pressure oc-
curs. Avoid low pressure, e.g., by means of ventilation openings in
the exterior wall.
- For each tumble dryer, there must be a cross section of 36 sq.in.
2
(237 cm
) per ventilation opening.
The tumble dryer draws in air at the back. Therefore, there must be
a sufficiently large gap between the back of the machine and the
wall.
This would otherwise hinder a sufficient flow of air as well as the
operational performance of the tumble dryer.
Observe the necessary spacing between the machine and the wall.
Do not reduce the gap between the bottom of the tumble dryer and
the floor (e.g., toe-kicks, deep pile carpet).
The tumble dryer must only be operated if the humid exhaust air
generated during drying is conveyed outside through installed vent
ducting.
The exhaust air should not be vented into a wall, a ceiling, or a con-
cealed space of building.
Exceptions regarding the design of the exhaust air management
system must be designed in accordance with the applicable local
building regulations. Seek approval from the relevant building in-
spector.
- While installing the ducting, keep the tumble dryer disconnected
from the power supply.
- Make sure that the plug connections are fully sealed.
- The duct is not to be assembled with screws or other fastening
means that extend into the duct and catch lint
- Only use heat-resistant materials with a temperature resistance of at
least 175°F (80°C).
- Only use rigid metal duct. Consult local building codes.
- Condensation will form in the exhaust air management system. A
condensate drain must therefore be placed at the lowest point in the
system.
The opening of the vent ducting (e.g., a wall pipe) must be arranged in
such a way that the humid exhaust air:
- does not flow back into the room where the tumble dryer is installed
- does not cause damage or unacceptable disturbance
