The current locally applicable regulations and laws must be observed!
1 .3

Area of application

– Intended use:
The MultiVent MV EC.. fans are designed for air ventilation and extraction in rooms and direct installation in duct sys-
®
tems. The fans are suitable for moving medium and small volumes of air against high resistances, at normal temperatu-
res from -20 °C to 60 °C (depending on type) and in the range of their performance curve. For operation under difficult
conditions i.e. high humidity, longer period of standstill, high pollution, excessive working conditions due to climatic,
technical or electronic influences, further inquiry and operation release is necessary as the standard version might not
be suitable. The motors have tropical insulation. It must be ensured that the standardised range of application is not
exceeded.
m
The operational temperature (see rating plate) must not be exceeded!
m
The fan may not be used outdoors and may not come in contact with water during operation!
m
Use in explosive atmospheres is not permitted!
Any other use than the intended use is prohibited!
– Reasonably foreseeable misuse:
The fans are not suitable for operation under difficult conditions, such as high levels of humidity, aggressive media, long
standstill periods, heavy contamination, excessive loads due to climatic, technical or electronic influences. The same
applies for the mobile use of fans (vehicles, aircraft, ships, etc.).
Usage under these conditions is only possible with release approval from Helios, as the standard version is not suitable
in this case.
– Improper, prohibited use:
Any use other than the intended use is not permitted! The conveying of solid matter or solid matter content > 10µm in
air and liquid is not permitted. Transport media, which affect the materials of the fan, and abrasive media are not per-
mitted. Use in explosive atmospheres is not permitted! Outside operation of the fan is not permitted.
1 .4

Personnel qualification

m
DANGER!
The electrical connection and commissioning as well as the installation, servicing and maintenance of the fan must
only be carried out by qualified electricians .
The MultiVent MV EC.. fans can be used by children over the age of 8 as well as persons with physical, sensory, or mental
®
disabilities or lack of experience and knowledge, if they are supervised or instructed with regard to the safe use of the unit and
they understand the resulting risks. Children must not play with the unit. Cleaning or user maintenance must not be carried
out by unsupervised children.
1 .5 Functional safety – Emergency operation
When using the fan in an important supply function, the plant is to be designed so that emergency operation is automatically
guaranteed in case of fan failure. Suitable solutions are, for example, parallel operation of two less powerful units with a sepa-
rate electric circuit, standby fan, alarm systems and emergency ventilation systems.
1 .6

Product service life

The motors are equipped with maintenance-free, permanently lubricated ball bearings. The units are designed for a
minimum service life of 30 000 h in continuous operation and constant load (S1 operation) with the maximum perfor-
mance in maximum permissible ambient temperature.
2 .0 Warranty claims – Exclusion of liability
All versions of this documentation must be observed, otherwise the warranty shall cease to apply. The same applies
to liability claims against Helios. The use of accessory parts, which are not recommended or offered by Helios, is not
permitted. Any possible damages are not covered by the warranty. Changes and modifications to the unit are not per-
mitted and lead to a loss of conformity, and any warranty and liability shall be excluded in this case.
2 .1 Regulations - Guidelines
If the product is installed correctly and used to its intended purpose, it conforms to all applicable EU guidelines at its
date of manufacture.
