Safety instructions explained
Danger
This symbol warns against the risk of injury.
!Please note
This symbol warns against the risk of material
losses and environmental pollution.
Note
Details identified by the word "Note" contain additional
information.
Target group
These instructions are exclusively intended for quali-
fied contractors.
■Work on electrical equipment may only be carried
out by a qualified electrician.
■The system must be commissioned by the system
installer or a qualified person authorised by the
installer.
Regulations to be observed
■National installation regulations
■Statutory regulations for the prevention of accidents
■Statutory regulations for environmental protection
■Codes of practice of the relevant trade associations
■All relevant safety regulations as defined by DIN, EN,
DGW, VDE and locally applicable standards
aÖNORM, EN and ÖVE
cSEV, SUVA, SVTI, SWKI and SVGW
Working on the system
■Isolate the system from the power supply (e.g. at a
separate MCB/fuse or a mains isolator) and check
that it is no longer 'live'.
Note
In addition to the control circuit there may be several
power circuits.
Danger
Contact with live components can result in
severe injuries. Some components on PCBs
remain live even after the power supply has
been switched off.
Prior to removing covers from the appliances,
wait at least 4 minutes until the voltage has
completely dropped out.
■Safeguard the system against reconnection.
!Please note
Electronic assemblies can be damaged by elec-
trostatic discharge.
Prior to commencing any work, touch earthed
objects such as heating or water pipes to dis-
charge static loads.
Repair work
!Please note
Repairing components that fulfil a safety func-
tion can compromise the safe operation of the
system.
Replace faulty components only with genuine
Viessmann spare parts.

Auxiliary components, spare and wearing parts
!Please note
Spare and wearing parts that have not been tes-
ted together with the system can compromise its
function. Installing non-authorised components
and making non-approved modifications or con-
versions can compromise safety and may inva-
lidate our warranty.
For replacement, use only spare parts supplied
or approved by Viessmann.

Intended use
Ventilation systems are intended solely for installation
and operation in compliance with DIN 1946-6, with due
attention paid to the associated installation, service
and operating instructions. Ventilation systems are
intended exclusively for controlled mechanical ventila-
tion.

Intended use presupposes that a fixed installation in
conjunction with permissible, system-specific compo-
nents has been carried out.
Commercial or industrial usage for a purpose other
than mechanical ventilation of living spaces shall be
deemed inappropriate.
Any usage beyond this must be approved by the man-
ufacturer in each individual case.
Incorrect usage or routing of the ventilation system is
prohibited and results in an exclusion of liability. Incor-
rect usage also occurs if the components in the venti-
lation system are modified from their intended function.
Note
The ventilation systems are intended exclusively for
domestic use.
Product information
Note
For the routing of an air distribution system, a routing
plan is required, which should take into account air
flow rates, pressure drops and noise distribution. Rout-
ing an air distribution system without prepared engi-
neering plans can lead to irresolvable distribution sit-
uations.
Outdoor air/exhaust air ductwork
Via the outdoor air/exhaust air ductwork, the outdoor
air is fed into the ventilation unit and the exhaust air is
routed out of the building. The ductwork comprises
thermally insulated pipes and bends made of EPP and
metal, silencers and outside air/exhaust air apertures.
On the supply and extract air side, the headers con-
nect the ventilation unit with the air distributors.
Modular flat/round supply air/extract air ductwork
The modular flat/round ductwork is used to distribute
the supply air and to collect the extract air. The low
installed height of the flat ducts makes routing on the
sub floor level possible. The components have an air-
tight connection. The round duct is also suitable for
routing in concrete.
The modular design of the air distribution system
means it can be combined in many ways using the
round and flat duct components. This gives you the
flexibility to adapt the installation situation as required.
The distributors can be central or decentralised.
Various air distributors are available for routing the
ductwork on the supply and extract air sides. Some of
these air distributors are fitted with a silencing function.
The supply air flow rates are adjusted by the use of
restrictor elements (flat and round).

The air is distributed from the ventilation unit to the liv-
ing spaces (supply air), and from wet areas to the ven-
tilation unit (extract air) via the modular flat/round sup-
ply air and extract air ductwork.
Elements of the supply air/extract air ductwork
■Various air distributors
■Round ducts
■Flat ducts
■Connecting elements
■Silencers
■Various air outlets
Position air distribution boxes and 2-way air distribu-
tors near the ventilation unit.
Route supply air and extract air ducts directly from the
relevant air distributors to the individual rooms.
Installation information
■Danger
Sharp edged metal parts can cause cuts.
Wear safety gloves during installation.
■In order to avoid complicated duct runs, install the
ventilation ductwork prior to installing the central
heating, water and waste water services.
■Ducts must not sag, to prevent condensate accumu-
lating.
■Contamination must not enter the ductwork.
■Lubricating paste is required to assemble the compo-
nents. Only use lubricating paste intended for EPDM.

Supply air/extract air valves
■Arrange the supply air and extract air valves in the
room geometry so that the air is routed as directly as
possible between rooms that are ventilated and
those from which air is extracted. At the same time,
ensure as broad a flow pattern as possible through
the entire room.
■Max. distance to the ceiling in the case of wall
mounting: 300 mm
Air routing between rooms
■Create an interconnected room air supply between
the rooms to be ventilated and those from which air
is to be extracted.
■For this, a gap under doors into the apartment is suf-
ficient. The correlation between gap height and air
flow rate is shown in DIN 1946-6 (see technical
guide).
■Where internal doors are tightly sealed, provide on-
site noise attenuated overflow vents in the internal
walls or in part of the door.

For routing air between different floors, an iris dia-
phragm is installed in the riser. The zinc-plated steel
iris diaphragm adjusts the air flow rates.
Preventing flow noise and pressure drop
■Install air distribution boxes close to the ventilation
unit.
Maximum length of supply air and extract air ducts
between the ventilation unit and the air distribution
box: 5 m
■Symmetrical layout of the supply air and extract air
ducts
■Short runs, few bends
■In areas where greater attenuation is required, install
one silencer (accessories) each in the supply and
extract air ducts between the air distribution box and
ventilation unit.
■In areas where greater attenuation is required, pro-
vide additional silencers between adjacent living
rooms, bedrooms and toilets.
■To reduce the pressure drop in ducts, fit central ris-
ers/downpipes with EPP pipe DN 160 or DN 180
where appropriate.
Measures against structure-borne noise
The ventilation units have sound-absorbing adjustable
feet or rubber washers to counteract structure-borne
noise transmission. Therefore, if appliances are moun-
ted on concrete or screed floors and solid walls, no
additional measures need be taken.
When a unit is installed on wooden ceilings, we recom-
mend additionally insulating it against vibration by
means of a concrete slab or anti-vibration mounts.
Never position the ventilation unit in the centre of a
ceiling if the ceiling is constructed with wooden beams.
Note
This also applies when using a mounting base (acces-
sories).
