Information on surface quality
The surfaces of the products conform to the generally applicable industrial
standard. The surface quality may change during the production period.
This has no effect on strength, dimensional stability and dimensional
accuracy.
The color pigments in the paints used perceptibly react to UV light over
the course of time. This does not however in any way affect the
technical properties of the products. The product is to be protected against
UV radiation to prevent the formation of patches and fading. Changes in
color are not a reason for complaint and are not covered by the warranty.

→ Wear safety shoes and cut-resistant safety gloves.
NOTE
Damage to the device from vibration
Bearing damage, shorter service life
→ The fan must not be subjected to force or excessive vibration
from sections of the installation.
→ If the fan is connected to air ducts, the connection should
be isolated from vibration, e.g. using compensators or similar
elements.
→ Ensure stress-free attachment of the fan to the
substructure.
;
The fan may not be handled in the area around the inlet nozzle during
transport and installation.
There is a risk of damage to the impeller.
;
Check the device for transport damage. Damaged devices are not to
be installed.
;
Install the undamaged device in accordance with your application.
4.1.1 Installation of RadiPac fan
Use is always to be made of appropriate hoisting equipment and a
suitable lifting device when transporting the fan for installation purposes.
Only suitable round slings are to be used for this purpose (see Chapter
3.4 Technical description for weight of product). Use four round slings
passed around the struts for lashing purposes. Position the round slings
as shown in the hoisting diagram below. Make sure that the struts of the
support bracket on the left and right of the motor are vertical. During
installation, only transport the fan in the installation position as shown in
the product drawing. Heed the information given on the device! During
transportation, an acceleration of 2 g must not be exceeded.
