CHAPTER 2
GENERAL INFORMATION
Centrifugal in-line fans – InlineVent
• A uniform inflow and free outlet must be ensured!
• When using a vented fire place (chimney) in a ventilated room, there
must be sufficient supply air for all operating conditions (consult chim-
ney sweep).
The current locally applicable regulations and laws must be observed!
1.3
Application
– Normal use:
The centrifugal in-line fans RR for conveying normal or slightly dusty (particle size < 10 µm), less aggressive and humid
air, in moderate climates and in the range of their performance curves, see Helios sales documents / internet. Operation
is only admissible with fixed installation within buildings. The maximum admissible media and ambient temperature can
be found on the type plate.
– 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 permit-
ted. Use in explosive atmospheres is not permitted! Outside operation of the fan is not permitted.
1.4
Personnel qualification
DANGER!
The electrical connection and start-up as well as the installation, servicing and maintenance of the fan must only be
carried out by qualified electricians.
Centrifugal in-line fans RR can be used by children over the age of 8 as well as persons with physical, sensory, or mental dis-
abilities 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. Under normal operating condi-
tions, they should be replaced after approximately 40,000 operating hours, standstill or long storage periods of more
than 2 years.
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
Certificates - 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.
2.2
Shipping
The fan is packed ex works in such a way that it is protected against normal transport strain. Carry out the shipping
carefully. It is recommended to leave the fan in the original packaging.
2.3
Receipt
The shipment must be checked for damage and correctness immediately upon delivery. If there is any damage,
promptly report the damage with the assistance of the transport company.
If complaints are not made within the agreed period, any claims could be lost.
2.4
Storage
When storing for a prolonged time, the following steps are to be taken to avoid damaging influences: Motor protection
by dry, airtight and dust-proof packaging (plastic bag with desiccant and humidity indicators). Vibration-free, water-tight
and constant-temperature storage at a temperature in the range -20 °C to +40 °C.
In case of a storage period of more than three months or motor standstill, maintenance must be carried out before
