inVENTer®Quality and Guarantee
The inVENTer ventilation system is manufactured according to the DIBt permit and strict
quality guidelines. Only high-quality and corrosion resistant materials such as plastic,
ceramic and stainless steel are used.
The inVENTer ventilator is designed for continuous operation. With only an average 2.5
W connection capacity per ventilator (including controller losses), about 40 times more
(heat) energy is saved than used.
We are subject to a statutory warranty period of 2 years. For an additional fee it is
possible to extend the warranty for another 3 years. Additionally, we provide a
supplemental guarantee of 8 years on the ceramic heat storage tank.
The manufacturer does not assume warranty if the installation was not completed
according to the assembly instruction.
Intended use
The inVENTer ventilation system is used to ventilate and aerate living spaces and similar
rooms (e.g., offices, medical offices, etc.) and is installed on exterior walls. When
planning, installing and operating, please follow the stipulations and valid building codes.
The iV twin was especially developed for individual room ventilation.
¾The inVENTer ventilator may not be used in rooms that are subject to high levels of dust
accumulation (e.g., in model construction) and may not be used in rooms with aggressive
or corrosive gases.
¾The inVENTer ventilator may not be operated without a dust filter and inner cover plate.
¾Please close the inVENTer dust-tight during construction work, and put the ventilation
system into operation only after concluding the construction work. Please inform the
respective contract builders and responsible construction manager.
¾The inVENTer ventilator is not suitable for building drying during the construction phase
and for ventilation while working with high levels of dust accumulation (e.g. sanding
plaster board).
The manufacturer is not liable for damages created by improper installation and non-
compliance with intended use.
Safety
Please always follow the safety, warning and processing information of the materials and
tools used, as well as the points specified in this instruction. Furthermore, when carrying
out the work and using materials and tools, the current applicable legislature must be
followed. Non-compliance can lead to damages to the device or bodily injuries.
The inVENTer ventilation system works with a low-voltage protector. Therefore, the
inVENTer ventilator may never be directly connected to the 230 V mains supply; rather it
must be connected via a controller. Damages caused by incorrect installation are not
included in the warranty obligation.
Attention for fireplaces!
Please follow the valid building codes and regulations (e.g., FeuVO [Firing Regulation])!
Before installing the ventilation system please talk to your chimney sweeper!

Attention! Please carefully read all of the instructions before starting the assembly. For
questions please contact your authorised dealer and construction manager. Assembly
faults can impair proper function, cause injuries and/or lead to loss of warranty.
Only trained qualified personnel may complete the assembly work. Only qualified
experts may complete the electrical installation.
Ventilation planning / General notes
Before starting the work, a project should be presented that indicates the number of
ventilators, the principal locations of the ventilators, the ventilation principle (cross
ventilation, single room ventilation, aeration), and the respective applicable controllers.
The following principle rules apply for the ventilation function:
Operate ventilators in pairs:The supply air should correspond to the exhaust quantity.
Every supply air conveying ventilator has a ventilator that transmits exhaust air at the
same time. The ventilators are allocated via the project, which must be checked and
possibly changed after controller start-up. During the delivery state the ventilators are set
to "exhaust". With correct installation, the iV twin ensures operation in pairs.
Synchronisation:When utilising several ventilators activated by several controllers,
synchronous collaboration must be observed. See notes in the controller instruction. All
controllers should be connected via the mains fuse to the main circuit of the house. The
iV twin works autosynchronous if assembled correctly.
Cross ventilation: The local ventilation system is based on free air movement between
the individual inVENTer ventilator pairs. Therefore, inside doors many not be closed
airtight. Overcurrent measures must be planned: Air space of about 10 mm below the
door, unscrewing the door hinges by 5mm, using a ventilation grille or similar. For the iV
twin these measures are not necessary.
Please find out from your planner if a "RAL installation" is necessary before
installation. Suitable materials are already provided on site if necessary.

Specify the installation location, wall opening and cable installation
Inside
¾Minimum distance of 100 mm
surrounding from the edge of the wall
mounting sleeve to the wall/ceiling
¾Later, there must be a space of at least
250 mm in front of the wall for
maintenance work (do not cover with
cupboards).
Outside
¾When specifying the installation location
consider the outside view
(e.g., exterior hood flush with lintel), see
drawing to the left.
¾Observe the minimum distance to
bordering components [F = edge of the
window reveal] ÆY ≥250 mm
¾When creating the opening, make sure
that no one on the outside can be injured
by falling masonry.
¾Create a wall opening of 270 x 150 mm²
in height and width. Options would be, for
example, creating two hollowed drill holes
of Ø 150 mm or one of Ø 295 mm (see
drawing to the left).
