DANGER
Smoke Exhaust Fans F300/F400/F600 – B AVD and B VAR
– The smoke exhaust fan must be operated at a nominal speed.
– The speed control must be bridged in a smoke extraction situation!
1 .9 Functional safety – Emergency operation
When using the fan in an important supply function, the plant is to be designed so that emergency operation is auto-
matically guaranteed in case of fan failure. Suitable solutions are, for example: parallel operation of two less powerful
units with a separate electric circuit, standby fan, alarm systems and emergency ventilation systems.
In order to maintain the smoke extraction function, an additional power supply is required in case of a power failure.
The wiring must have function preservation.
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
permitted and lead to a loss of conformity, and any warranty and liability shall be excluded in this case.
2 .1

Regulations - Guidelines

If the unit is installed correctly and used to its intended purpose, it conforms to all applicable regulations and EU gui-
delines 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. The fan must be kept in the casing or the
provided lifting lugs for transportation or installation – Observe transportation diagram! In this respect, only use
appropriate lifting equipment and fastening devices. Weight information can be found in the table Chapter 5.0 on page
16 or the unit label.
Do not transport fan on the connection cables, terminal box or impeller!
Do not stand under suspended loads!
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). The storage place must
be water proof, vibration-free and free of temperature variations. Storage temperature -20 °C to +60 °C, and these limits
must not be exceeded.
The motor bearings must be turned at regular intervals (10 turns per month). In case of a storage period of more than
three months or motor standstill, maintenance must be carried out before commissioning. In this respect, the silent, free
movement of the impeller must be checked. The motor bearings must be replaced after a 2-year storage period. When
transhipping (especially over longer distances) check if the packing is adequate for method and manner of transportation.
Damages due to improper transportation, storage or commissioning are not liable for warranty.

Series
High-pressure in-line smoke exhaust fans
B VAR
Binding information on the individual fan types can be found on the type plate.
2 .6

Performance data

The motor type plate gives an indication of the electrical values; which must be coordinated with the local supply net-
work. The fan performances* were established on a test stand according to DIN EN ISO 5801:2010-12; they apply to
the nominal speed and standard design using an inlet nozzle, without a protection guard with unhindered inflow and
outflow and a pressure-side pipe section with 2.5 x diameter length. In this respect, different versions and unfavourable
installation and operating conditions can lead to a reduction of output.
