1 Use
1.1 Intended use
RoofVent
®
condens units are used to supply fresh air, for the
disposal of extract air and for heating with energy recovery in
high spaces. Also included under intended use are compli-
ance with the installation, commissioning, operating and
maintenance provisions (operating manual).
Any use beyond this is considered improper use. The
manufacturer shall not be held responsible for any damage
resulting from such use.
1.2 User group
RoofVent
®
condens units may only be installed, operated and
serviced by authorised and trained specialist personnel who
are familiar with the equipment and aware of the dangers
involved.
The operating manual is for English-speaking operating
engineers and technicians as well as specialists in building,
heating and ventilation technology.
1.3 Risks
RoofVent
®
condens units are built to correspond to the state
of the art and to current safety standards. However, despite
all precautionary measures taken, there are still some poten-
tial hazards which are not immediately obvious, such as:
■
Dangers when working with the electrical systems
■
During work on the ventilation unit, parts (e.g. tools) can
fall or be dropped
■
Dangers when working on the roof
■
Damage to devices or components due to lightning
■
Malfunctions as a result of defective parts
■
Hazards from hot water when working on the hot water
supply
■
Ingress of water through the roof unit if the access panels
are not closed correctly
Caution
Explosion hazard due to leaking gas. If you smell gas:
■
Avoid open flames and sparks
■
Do not smoke
■
Open windows and doors
■
Switch off the unit
■
Close gas shut-off cock
2 Construction and operation
The RoofVent
®
condens provides fresh air supply and extract
air removal as well as heating for large spaces (production
halls, shopping centres, sports halls, exhibition halls etc.). It
fulfils the following functions:
■
Heating (with integrated gas condensing boiler)
■
Fresh air supply
■
Extract air removal
■
Recirculation
■
Energy recovery
■
Air distribution via Air-Injector
■
Air filtration
A ventilation system consists of several autonomous
RoofVent
®
condens units and as a rule, works without supply
and extract air ducts. The units are decentrally installed in
the roof and are also serviced from roof level.
Thanks to their high output and efficient air distribution,
RoofVent
®
condens units have a large operating range. This
means that compared with other systems, only few units are
necessary to create the required conditions.
The ventilation unit includes a high-efficiency gas condensing
boiler. Thanks to this decentralised heat generation facility,
no boiler room is needed. Connection to a boiler system is
unnecessary.
2.1 Unit construction
The RoofVent
®
condens consists of the following compo-
nents:
■
Roof unit with energy recovery and heat generator
assembly in a self-supporting casing made from Aluzinc
sheet steel, insulated on the inside (Class B1)
■
Filter box: available in three standard lengths per unit size
for adjusting to specific dimensional requirements
■
Heating section
■
Air-Injector:
patented, automatically adjustable vortex air distributor for
draught-free air distribution over a large area
The unit is delivered in two sections: above-roof unit and
below-roof unit (see Fig. G1). The components are bolted
together and can be dismantled individually.
