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. The fan must be kept in the housing for transpor-
tation or installation. Only use appropriate lifting equipment and fastening devices.
Weight information can be found on the type plate.
Do not transport the fan on the connection cables, terminal box or impeller.
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, watertight
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
commissioning 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 transportati-
on, storage or putting into operation are not liable for warranty.
2.5

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.
2.6

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.
2.7 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.
2.8

Protection against contact

- SilentBox ® SB EC... are not delivered with fan protection guards as standard. Depending on the installation conditions,
protection against contact may be necessary on the suction and/or discharge side. Corresponding protection guards are
available as accessories.
- Fans which are protected by their installation method (e.g. installation in ventilation ducts or closed assemblies) do
not require protection guards if the plant provides the necessary level of safety. Please note that the operator is
responsible for complying with the current standard and can be held liable for accidents as a consequence of missing
protection systems.
2.9

Motor protection

All SilentBox ® SB EC... fans are equipped with an integrated electronic temperature monitoring system for the
EC motor and the electronics system. This system protects the motor from overloading and overheating.
m
If the thermal contacts are triggered frequently (standstill), the fan must be inspected by a specialist
according to chapter 1.4.

2.10 Condensation

If the fan is used intermittently, especially in a humid and warm environment, or if variations in temperature occur, con-
densation may build up in the motor and draining off must be ensured. In case of condensation in the ducting and fan
casing appropriate measures must be taken during installation (water sack, drainage line). Under no circumstances
must the motor come into contact with water.
