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 transporta-
tion, 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.
NOTE!
The maximum current during regular operation may deviate or be higher than the rated current!
Note type plate information!
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

Protection against contact

- SlimVent SV.. 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.
2.8 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.
An incorrect direction of rotation will lead to a breakdown, increased noises and increased power consumption, which
can destroy the motor.
2.9

Motor protection

All models are equipped with thermal contacts, which are wired in series with the winding and automatically deactivate
and reactivate after cooling down.
NOTE!
Triggered thermal contacts indicate incorrect operating conditions, the cause of which must be corrected.
If the thermal contacts are triggered frequently (standstill), the fan must be inspected by a specialist according
to chapter 1.4.

2.10 Condensation

In case of intermittent operation with humid and warm airflow and if variations in temperature occur (intermittent duty),
condensation may build up in the motor and draining off must be ensured. If condensation can form in the ducting or
fan housing, appropriate measures must be taken during installation (water sack, drainage line). Under no circumstan-
ces must the motor be exposed to water.
