20°C) and +356.0°F (+180°C) for
special versions with heat shield.

The fan is designed for S1 opera-
tion (continuous operation) and S9
operation (uninterrupted operation
with non-periodic load/speed
change) (according to IEC 60034-
1). By way of derogation, a maxi-
mum of 27 circuits per hour are per-
mitted.
•
In the case of damp media, a con-
densation bore can be ordered.
This is introduced into the housing
by the manufacturer.
The product may only be used if:
•
This is in technically perfect condi-
tion
•
The staff has the necessary safety
and danger awareness.
•
The instructions in the operating in-
structions are followed.
2.5 Predictable Misapplication
For a purpose other than the intended
use listed here, the fan is not intended.
In principle, a use other than the in-
tended use is considered to be im-
proper. This means that safe operation
is no longer guaranteed. The operator
and not the manufacturer is responsible
for all personal injury and property dam-
age resulting from the improper use.
Predictable misuse also includes:
•
The promotion of:
-
Aggressive media
-
Abrasive media
-
Adhesive media
-
Toxic media
-
Explosive media
-
very humid (with drop for-
mation) media
•
Installation in an explosive atmos-
phere
•
Series or parallel connection of sev-
eral fans
•
Outdoor installation without special
measures
•
Conversion and modification
2.6 Conversions and Changes
Modifications to the fan are not permit-
ted for safety reasons.
The use of non-original spare parts may
remove liability for the resulting conse-
quences. Therefore, always use only the
predetermined spare parts, this applies
especially to safety-relevant compo-
nents (impeller, motor, ball bearings,
runners, etc.).
2.7 Residual Risks
Electric fans are built according to the
state of the art and are characterized by
a high degree of operational reliability.
Since the fans are very powerful ma-
chines, the following safety instructions
must be strictly observed in order to
avoid injury, damage to property and the
machine itself.
Overview of Danger Points
The residual hazards of the fan are di-
vided into the following four areas:
