INSTALLATION

RD.. and VD.. – Roof Fans
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 pro-
vided lifting lugs (over Ø 450) for transportation or installation.
In this respect, only use appropr ate lifting equipment and fastening devices. Weight information can be found on the
label on the unit.
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). Vibration-free, water-tight
and constant-temperature storage at a temperature in the range -20 °C to +40 °C, which must not be exceeded. 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.

Series

These installation and operating instructions describe the following Helios roof fan series:
Series
Radial roof fans RD..
Vertical roof fans VD..
Binding information on the individual fan types can be found on the type plate.
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: 2010-12; they
apply to the nominal speed and standard design using an inlet nozzle, without a protection guard and with unhindered
inflow and outflow. Different versions and unfavourable installation and operating conditions can lead to a reduction
of output.
2.7

Noise data

The noise data* also refers to the directive mentioned in section 1.4. Housing variations, unfavourable operating condi-
tions and many other things can lead to an increase in the specified catalogue values. Data that refers to certain distan-
ces (1, 2, 4 m) apply to free field conditions. With regard to installation, the sound pressure level can differ significantly
from the catalogue data, as it is highly dependant on the installation conditions, i.e. on the absorption capability of the
room, the room size among other factors.
3.0 Installation
The installation site must be suitable for the roof fan in type, composition, ambient temperature and ambient medium.
The substructure must be level and sufficiently load bearing. The mounting elements should be as level as possible
(max. 5 % incline), however, installation on inclined surfaces up to 45° angle of inclination is possible (e.g. pitched roof
base type SDS, Accessories).
3.1

Mounting

The roof fans are designed for base installation. The base plate of the fan has 4 holes for mounting to the base.
Place the fan with the base plate on the base (see Accessories). In this respect, observe the
respective installation and operating instructions for flat roof bases. Tighten the anchor screws equally
to avoid warping.
NOTE: If an RDD/VDD 710/6 unit is installed in connection with a back draught shutter (RVS/RVM 710), an ex-
tension duct (VR 710) is required between the unit and the back draught shutter.
NOTE: An extension duct (VR 710) is not required for a base attenuator (SSD 710).
