Mounting of centrifugal fans design RG.. / RD..
Fastening depending on housing design on
fl
ange or fastening brackets.

An additional bracket is required for fastening to the
fl
ange. This is available as an accessory.
Ensure that the clearance (gap)

the fan impeller and the stationary housing section is
constant. Distortion due to uneven surface may lead to
fan failure.
Attention!
•
Avoid structural damage or stress with installation. Flange and mounting bracket must be

on a level surface.
•
Provide screwed connections with suitable screw locking.

Erecting the equipment: Design ER... / GR...
•
To avoid the transference of disruptive vibrations, we recommend de-coupling the entire plug fan to
avoid sounds transmitted through solids. (Spring and/or attenuation units are not a constituent part
of the standard scope of delivery). Look at our catalogue for positioning the decoupling elements or
request a dimensions sheet stating the type designation and Part.-No.
•
Erect in the open air only if this is expressly mentioned and con
fi
rmed in the ordering information.
There is a risk of damage to the bearings if the fan remains stopped in a moist environment. Avoid
corrosion by suitable protective measures. Roo
fi
ng is required.
•
In the case of a vertical motor axis, the respective lower condensation drain hole must be open.
•
The GR design in position
“
H
”
(horizontal shaft) should be installed in the preferred direction. The
cable guides should point downwards (angled sideways by approx. 30
°
). This is indicated by the
“
OBEN/TOP
”
warning sign on the device.
Attention!
•
All contact points must be
fi
xed securely. If the
fi
xing is inadequate there is a risk of the fan
overturning.
•
Making your own alterations/conversions on the fan module is unacceptable - safety risk.
