SYSTEM OVERVIEW: IV14-MAXAIR VENTILATION DEVICE
8iV14-MaxAir ventilation device | Installation instructions
2 System overview: iV14-MaxAir ventilation device
The iV14-MaxAir ventilation device is a decentralised ventilation device with heat recovery and is
designed for increased air ow requirements (performance-plus device). It is suitable for installa-
tion in new buildings as well as for retrotting in older buildings and is particularly suitable for use
in large living spaces and similar commercial premises (e.g. o󰀩ces, doctors' surgeries, lounges,
etc.). Installation is generally carried out in the exterior wall.
The ventilation device consists of a wall sleeve in which the thermal accumulator insert is
mounted. A lockable inner cover conceals the iV14-MaxAir discreetly from the interior. The lter
integrated into the inner cover ensures that no pollen or dust from outside enters the interior.
Outside, a driving rain-proof cover conceals the components of the ventilation device.
The thermal accumulator insert includes a ceramic thermal accumulator and inVENTron, two
guiding vane elements and the Xenion EFP reversible fan. The guiding vanes on both sides
of the fan serve to straighten the air ow and ensure more e󰀩cient ow through the thermal
accumulator. The unique geometry of the Xenion EFP reversible fan e󰀨ectively reduces sound
transmission.
The standard length of the wall sleeve is 495 mm. For thicker walls, a wall sleeve and insert with
a length of 745 mm can be ordered as an alternative. Both versions can be shortened on site.
The ventilation device is controlled via one of the following inVENTer system controllers1):

SYSTEM OVERVIEW: IV14-MAXAIR VENTILATION DEVICE

2.2 Function
Decentralised ventilation
Decentralised ventilation systems combine extract and supply air and are based on free air
movement between individual pairs of ventilation devices (cross-ventilation). The cross-ventila-
tion principle allows the air to circulate through the entire residential device and also su󰀩ciently
ventilate interior living spaces. Each ventilation device is mounted in its own air duct so as not to
obstruct other ventilation processes.
The decentralised iV ventilation systems with heat recovery consist of ventilation devices
arranged in pairs with simple air ow. They operate according to the principle of heat recovery by
changing the direction of the fan. The integrated thermal accumulator is charged with the thermal
energy of the room air as it ows externally (extract air). After 70 seconds, the reversing fan
changes the direction of rotation each time. After the direction of rotation has changed, the heat
accumulator releases the stored heat energy to the incoming fresh air (supply air).
For this principle to work correctly and to ensure pressure stability in the room, the supply air
volume must always correspond to the extract air volume, i.e. at least two ventilation devices are
required. These are operated in pairs in push-pull mode: another ventilation device is assigned to
the ventilation device that delivers supply air and at the same time removes used extract air from
the interior to the outside.
You operate the iV ventilation systems intuitively with the matching inVENTer controllers.
Di󰀨erent operating modes or the air volume ows can be set individually.
The most important components of the iV system are the ceramic thermal accumulator, the
reversing fan, air guiding vanes for straightening the air volume ow, lters for di󰀨erent hygienic
requirements, a closable inner cover and an outer cover. A control device (controller) completes
the system.

iV14-MaxAir ventilation device | Installation instructions
Ventilation device iV14-MaxAir
The iV14-MaxAir ventilation device is used to provide ventilation for living spaces and living space-
like commercial premises. An integrated ceramic thermal accumulator ensures optimum heat
recovery.
The iV14-MaxAir ventilation device is a ventilation device with simple airow and works according
to the principle of heat recovery by changing the direction of the fan.
Thanks to a high pressure build-up and the active speed control of the motor (integrated wind
pressure stabiliser) in the Xenion EFP reversible fan, the air ow in the system is kept almost
constant even in the event of weather-related pressure uctuations. Thus, the sensitivity of the
air ow to pressure uctuations corresponds to class S2 according to EN 13141-8 (max. 20 % air
ow deviation at ± 20 Pa).
In order to ensure the full functioning of the ventilation device throughout the entire year, a tem-
perature sensor is integrated into the Xenion EFP reversible fan. This measures the temperature
of the air ow. If the temperature falls below +5 °C, the reversible fan is automatically switched to
extract air mode for 4 cycles. This allows the thermal accumulator to heat up again and prevents
cooling of the interior due to cold supply air. During this phase, the operating mode that has been
set on the controller is ine󰀨ective. Subsequently, the controller switches the ventilation device
back to the originally selected mode.
As standard, a washable ISO Coarse 60 % class dust lter is integrated into the inner cover. This
lters coarse dust and allergenic particles (such as coarse ower pollen) from the air before they
can enter the interior. The dust lters can be used regardless of the season.
Optional pollen and activated carbon lters are available for special requirements.

4.2 Create wall opening
CAUTION
Falling masonry when creating the wall opening
can lead to physical injuries and /or damage to property!
• Install protection against falling masonry on building exterior.
• Remove objects from the immediate vicinity of the building's exterior.
In new buildings we recommend the use of the optional Simplex D200 wall installation system,
D225 wall block, or Woodplex for timber post and beam construction.
Observe the minimum distances and the installation position of the ventilation device.
Consult your planner before installation if you are at all uncertain!
Create the wall opening through core drilling
Power drill with core drilling attachment or milling drill Ø 225 mm
Requirements:
• The masonry must be dry and in a load-bearing
condition.
• No load-bearing elements in the position of the drill
hole.
►Drill a wall opening, Ø 180 mm at installation
position of ventilation device.
The wall sleeve must have a slope of 1 – 2°
to the exterior wall side. Alternatively the
drilling can be carried through with a slope.
The wall opening for the ventilation device has
been created.

4.3 Laying the cables to the wall opening of the ventilation device
CAUTION
Exposed electrical components.
Injury caused by live components (16 V DC)!
• Installation and connection must only be performed by qualied and trained personnel.
Once the wall opening has been created, the cables necessary for operating the ventilation
system are laid to the wall opening for the ventilation device. They connect the valve gate of the
ventilation device with the control components and thus establish signal transmission and/or
voltage transmission between the controller and the Xenion EFP reversible fan.
NOTICE: Cable to the wall opening of the ventilation device not
laid. No connection of the reversible fan possible!
Routing of the cables to the wall opening for the ventilation device
must be done in this installation step. The routing of the connecting
cables between the controllers and the Xenion EFP reversible fan
is not part of this documentation. For more information, see the in-
stallation and operating instructions for the corresponding controller.
