Product description
The exterior-wall air outlet aV100 ALD is used to provide outdoor-air
ventilation in residential units in accordance with DIN 18017-3 and
DIN 1946-6. It consists of an insert with adjustable inner cover,
integrated back-draught shutter and filter, as well as a wall sleeve and
exteriour closure. Installation is carried out in the exterior wall.
The ALD insert, including all filters and back-draught shutter, is easily
accessible from the interior. The air volume is regulated via the inner cover,
which includes a mechanism for changing the opening angle.
Installation conditions
• The aV100 ALD must not be covered by cabinets or protruding
constructions. Outside air must be able to flow in freely.
• Maintain a minimum circumferential clearance of 100 mm.
• Installation should be performed close to the ceiling to obtain better air
distribution.
• Install the wall opening above a radiator. This ensures that the inflowing air
is pre-heated when entering the interior.
• The unit must not be installed above delicate furniture, surfaces or
pictures.
• Do not place the unit near a room thermostat.
• Position the ventilation unit in a way, that persons in the common area are
not exposed directly to the flow. Maintain a distance of 1 – 1.2 m to the
common area.
• In order to ensure that the device does not interfere with other ventilation
processes and that its functioning is not affected by them, it must always
be installed in its own wall sleeve.
• The velocity of inflowing air should be kept to a minimum required in order
to avoid cold draughts.

User and safety instructions
This documentation provides an overview of the product and basic
safety precautions for safe and proper operation of your ventilation unit.
The safety and warning instructions in these operating instructions have
a uniform structure and are marked with a symbol on the left side of
the instruction. A signal word above the text indicates the severity of
the hazard that may occur unless preventative measures are taken. If
several hazard levels exist, the highest level safety instruction is always
used.
CAUTION: Direct danger of minor/significant injury.
NOTICE: Imminent or possible damage to property.

Before performing any work on the system, read the user
instructions carefully and observe all information that refers to
installation and cleaning. Non-observance of safety warnings may re-
sult in injury and/or property damage. Observe the relevant standards,
regulations and guidelines, especially the applicable building codes and
re and accident prevention regulations issued by the respective trade
association. Installation may only be carried out by qualied personnel.
The aV100 ALD is designed to supply outdoor air in residential areas or
similar. In particular, it must not be used in environments that contain a
high concen-tration of oil or grease, areas in which extreme dust loads
or inammatory, aggressive and corrosive gases, liquids or vapours
may be present, or to dry buildings.
Installation example for controlled ventilation:
The aV100 ALDs are designed to supply outdoor air for exhaust and extract
air systems. They are installed in the supply air room.
Observe the balance and room compounds between the extract air sys-
tem’s outflow and the inflow achieved by the aV100 outdoor-air inlets. For
questions concerning the exact number of outdoor-air inlets needed consult
you sales representative or our technical service department.
