Centrifugal Fan Boxes – SilentBox
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.
2.1 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.
2.2 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.
2.3 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 housing for trans-
portation or installation. Only use appropriate lifting equipment and fastening devices.

DANGER!
Weight information can be found on the type plate.
Do not transport the fan on the connection cables, terminal box or impeller.
2.4 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.
2.5 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 start-up according to chapter
8. In case of reshipment (above all, over longer distances; e.g. by sea), it must be checked whether the packaging is
suitable for the form and route of transport. Damages due to improper transportation, storage or putting into operation
are not liable for warranty.
2.6 Performance data
The unit type plate gives an indication of the mandatory electrical values; which must be coordinated with the local
supply network. The fan performances* were established on a test stand according to DIN EN ISO 5801.
NOTE!
The fan types SB 125 A , SB 125C, SB 160 B, SB 160 D, SB 250 C have forward -curved centrifugal impellers (Fig. 2).
These have the characteristic that the power requirement decreases with increasing pressure difference. Lower power
consumption than the rated current means no reduced output (Fig. 1).
Fig. 2
NOTE!
The maximum current in regular operation may deviate or be higher than the nominal current! Observe unit
type plate data!
2.7 Noise data
Noise data that refers to certain distances apply to free field conditions. With regard to installation, the sound pressure
level can differ significantly from the catalogue data, as it is highly dependent on the installation conditions, i.e. on the
absorption capability of the room and the room size among other factors.
2.8 Air flow direction and direction of rotation
The fans have a fixed direction of rotation and air flow direction (they are not reversible), which are marked on the units
with arrows (direction of rotation red, air flow direction blue). The air flow direction can be set through the installation.
Incorrect direction of rotation can lead to lower air volumes, increased noise levels and increased power consumption,
which can destroy the motor.
