Ventilation System iV-Twin+
•
Installation and Operating Instructions
• NOTE:
Observe the specified minimum distances on both sides of the wall and on the front
to avoid mixing different types of air and to ensure access to the unit and its components. A
minimum distance of 1.2 m must be maintained between adjacent air openings. (
, page 12
et seq.).
• NOTE:
The wall sleeve must be integrated diffusion-open to the outside and diffusion-tight
to the inside in compliance with structural specifications in the building shell (air-tightness
level) ("RAL installation"). Material must be provided on site. After installing the wall sleeve,
return the wall structure to the wall sleeve and observe the necessary locking levels to avoid
interrupting the thermal insulation composite system. Consult your planner before installation!
• NOTE:
Install the wall sleeve with a gradient of 1 – 2° to the outer wall to ensure that any
condensate that may develop is drained off.
• NOTE:
Do not install the ventilation unit in places where direct contact with splash water is
possible. Observe the requirements of VDE0100 when selecting the installation location.
• NOTE:
In order to avoid algae colonisation around the weather protection hood, the
installation instructions must be followed exactly (attach all sealing strips!). We recommend
biocidal presetting/water-repellent pre-treatment of the facade surface around the weather
protection hood. Ask your planner!
• NOTE:
When attaching components to (exterior) walls with insulation, use insulation dowels
to ensure secure fastening of the components.
Insulation dowels are not included with the product, they are optionally available!
• NOTE:
To seal the joints on all external closures, only use a permanently elastic sealing
compound suitable for outdoor use!
• NOTE:
The structure of the ventilation unit has a separation of the air volume flows in
the wall installation sleeve. During and after installation, make sure that the vertical air
volume flow separation is ensured over the entire system!
• NOTE:
The device has scratch-sensitive plastic surfaces. In particular, do not touch the inner
cover with oily and/or dirty hands. Avoid contact with sharp or pointed objects such as rings.
Wiring / connection of the reversing fan
• CAUTION:
The electrical connection of the system may only be carried out by qualified
electricians.
• NOTE:
If the ventilation system is operated with safety extra-low voltage, it has an operating
voltage of 6 – 16 V DC. In this case, it must not be connected directly to the 230 V mains
supply, but must always be connected and operated via a controller.
• NOTE:
Laying cables whose sheaths are not plaster-resistant under plaster will result in
short circuits and cable fires! Lay cables without a plaster-resistant cable sheath in the empty
conduit.
• NOTE:
Remove the cable sheath completely from the fan BUS to avoid cable breakage when
inserting the inner cover, otherwise the inner cover cannot be inserted.
• When using several ventilation units controlled by several controllers, you must ensure
that the ventilation units are synchronized with each other (see Installation and Operating
instructions for Controllers). You should connect all controllers via a mains fuse in the in-
house distribution board.
Cleaning and Maintenance
• CAUTION: The cleaning or maintenance of the device must not be carried out by
children and/or persons who, due to their physical, sensory or mental abilities or
their inexperience or ignorance, are unable to do so safely. Young children must be
supervised to ensure that they do not play with the device.
• CAUTION:
Disconnect power for cleaning and maintenance and wear gloves.
• NOTE:
The device has scratch-sensitive plastic surfaces. Do not touch the inner cover with
oily and/or dirty hands. Avoid contact with sharp or pointed objects such as rings.
• NOTE:
Do not use strong cleaning agents or solvents. Use a soft damp cloth to clean the
plastic surfaces.
• NOTE:
Never use the device without a filter and inner cover.
• NOTE:
Remove/avoid obstructions that could prevent access to or removal of components of
the ventilation unit.
If your device is defective, contact your local factory representative or our technical service.
Improper use will result in the exclusion of any liability claims.
Improper use
Any use which is not mentioned in the chapter "Intended use" shall be deemed as improper
use.
In particular, do not install/operate the device in areas where the following may occur:
• Environment with high oil or grease content.
• Flammable, aggressive and corrosive gases, liquids or vapours.
• Extreme dust pollution.
• Ambient temperatures outside -20 – 50 °C.
• Obstacles that hinder access to or removal of components from the ventilation unit.
Qualified personnel
The device/system may only be set up, operated and cleaned in conjunction with this
documentation and the documentation for the controllers.
Installation and Mounting
Assembly, electrical connection and initial commissioning of the device/system may only
be carried out by qualified personnel. Qualified personnel within the meaning of the safety
information in this documentation are persons who are authorized to assemble, commission
and mark devices, systems and circuits in accordance with the standards of safety technology.
Cleaning and Maintenance
The necessary cleaning and maintenance work can be carried out by the user of the system
himself after a short briefing. The cleaning or maintenance of the device must not be carried
out by children and/or persons who, due to their physical, sensory or mental abilities or their
inexperience or ignorance, are unable to do so safely.
Conformity
The ventilation unit complies with the technical safety requirements and standards for
household electrical appliances. It is in conformity with the applicable directives
of the European Union:
• 2014/30/EC: Electromagnetic compatibility
• 2009/125/EC: Eco-Design
• 2014/35/EC: Low voltage
• 2011/65/EC: RoHS
