2.1
Intended use
The appliance is a decentralised ventilation unit with heat recovery. The appliance is designed for the ventilation of individual
rooms or partial ventilation of apartments. The appliance is built
into the external wall.
The appliance is intended for domestic use. It can be used safely
by untrained persons. The appliance can also be used in non-domestic environments, e.g. in small businesses, as long as it is
used in the same way.
Any other use beyond that described shall be deemed inappropriate. Observation of these instructions and of the instructions
for any accessories used is also part of the correct use of this

Appliance description
This appliance works according to the principle of regenerative
heat transfer. Heat exchange sections are located in the air flow.
These appliances only function in pairs in alternate operation. One
appliance operates for approx. 40 seconds in supply air mode,
the other operates simultaneously in extract air mode. The air
direction is then changed. This means that the total supply air
flow rates is equal to the total extract air flow rates.
In extract air mode, the heat exchanger absorbs the majority of
the thermal energy from the extracted indoor air. Once the fan
has switched to supply air mode, the heat exchanger transfers the
stored thermal energy to the inflowing outdoor air.
A filter outside the building reduces the penetration of dust and
other suspended matter. A filter inside the building reduces
contamination of the appliance.
WARNING Injury
The appliance may be used by children over 8 years of
age and persons with reduced physical, sensory or mental capabilities or a lack of experience and expertise,
provided that they are supervised or they have been
instructed on how to use the appliance safely and have
understood the potential risks. Children must never play
with the appliance. Children must never clean the appliance or perform user maintenance unless they are
supervised.
!
WARNING Injury
If there is a radio or police announcement ordering windows and doors to be kept closed, disconnect the appliance from the power supply.
Close the internal panel if it is not closed.
ff
Carefully push the internal panel towards the wall
until the internal panel is closed.
WARNING Injury
Operating the appliance with a partially installed fan unit
may cause injury or may damage the appliance.
WARNING Injury
The discharged cold air can cause condensation to be
formed in the vicinity of the air discharge.
ff
Ensure that no risk of slipping due to wet conditions
or ice formation occurs on adjacent footpaths and
driveways at low temperatures.

Safety
Only a qualified contractor should carry out installation, commissioning, maintenance and repair of the appliance.
9.1
General safety instructions
We guarantee trouble-free function and operational reliability only
if original accessories and spare parts intended for the appliance
are used.
9.2
Instructions, standards and regulations
Note
Observe all applicable national and regional regulations
and instructions.
WARNING Burns
In connection with the fire prevention regulations concerning the installation of ventilation systems, observe
all country-specific regulations and requirements.
9.3
Operation of the appliance in buildings with
combustion equipment
The term "combustion equipment" used below includes, for example, tiled stoves, fireplaces and equipment with gas combustion.
!
WARNING Injury
Ventilation units can generate negative pressure in the
dwelling. If combustion equipment is operating at the
same time, combustion exhaust gases can penetrate the
room where the combustion equipment is installed. It is
therefore important to observe a number of points for
simultaneous operation of a ventilation unit and combustion equipment.
The engineering, installation and operation of the ventilation unit
and combustion equipment must be carried out in accordance with
national and regional regulations.
Simultaneous operation
For simultaneous operation of combustion equipment and a mechanical ventilation system, we recommend choosing approved
room sealed combustion equipment (in Germany, with DIBt approval).
If open flue combustion equipment is operated in the dwelling
at the same time as a ventilation unit, combustion exhaust gases
must be prevented from penetrating the home as a result of possible negative pressure in the room.
The ventilation unit may only be operated in combination with
intrinsically safe combustion equipment. This combustion equipment has, for example, a draught hood or an exhaust gas monitor
and is permitted to be operated in conjunction with ventilation
units. Alternatively, external, tested safety equipment can be connected to monitor the operation of the combustion equipment.
For example, you can install differential pressure monitoring to
monitor the chimney draught and to switch off the ventilation unit
in the event of a fault.
The equipment for differential pressure monitoring must fulfil the
following requirements:
-- Monitoring of the differential pressure between the connection piece to the chimney and the room where the combustion equipment is installed
-- Possibility of matching the shutdown value for the differential
pressure to the minimum draught requirement for the combustion equipment
-- Floating contact to switch off the ventilation function
-- Optional connection of a temperature capturing device so
that differential pressure monitoring is only enabled when
the combustion equipment is in operation and so that unwanted shutdowns due to environmental influences can be
prevented
Note
Differential pressure switches that use the pressure
differential between the outdoor air pressure and the
pressure in the room where the combustion equipment
is sited as a response criterion are not suitable.
Note
We recommend installing and regularly maintaining a
carbon monoxide detector in accordance with EN 50291
for operation of any combustion equipment.
9.3.1 Planning safety measures
Together with the relevant authorities, engineers plan the safety
measures that are required for simultaneous operation of a ventilation unit and combustion equipment.
Alternate operation
Alternate operation means that, when the combustion equipment
is started, the mechanical ventilation system is switched off and/
or cannot be started. Alternate operation must be ensured by
appropriate measures, e.g. automatically enforced shutdown of
the ventilation unit.
9.3.2 Commissioning
When commissioning the ventilation unit, it is important to check
and document in the commissioning log that combustion exhaust
gases are not penetrating the dwelling in a quantity that is harmful
to health.
Commissioning in Germany
Acceptance is carried out by the local flue gas inspector.
Commissioning outside Germany
Acceptance must be carried out by a specialist. In case of doubt,
you must involve an independent expert in the acceptance procedure.

Appliance description
9.3.3 Maintenance
Regular maintenance of the combustion equipment is prescribed.
Maintenance includes checking the exhaust gas extraction system,
the free pipe cross-sections and the safety equipment. The relevant qualified contractor responsible must prove that is a sufficient
flow of combustion air.
connection between these rooms by ensuring that the overflow
air apertures are large enough.
Windowless extract air areas (e.g. kitchens, bathrooms and toilets)
should only be ventilated with the appliance if it is installed in an
external wall. Appliances should not be connected to a shaft or
pipeline.
