• The blower belt pulley must not be modi
fi
ed.
• The max. permissible blower speed must not be exceeded
(refer to the table on pages 18 - 25).
• Belt tension: refer to 5.4.
• Do not put the blower into operation if no protective grating
or equivalent belt guard is attached and securely bolted in
place. (risk of injury).
1.13 V-belt drive (if installed - applies to blowers
without
motor)
Note!
The blowers are equipped as standard with V-belt
pulleys for narrow V-belts according to DIN 7753.
To avoid premature damage to the deep-groove
ball bearings, the V-belt drives must be correctly
pretensioned. The V-belt drive must be rated us-
ing the calculation method speci
fi
ed by the belt
manufacturer.
• The blower belt pulley must not be modi
fi
ed.
• The max. permissible blower speed must not be exceeded
(refer to the table on pages 22 - 29).
• The belt drive and rotating parts must be covered with a
belt guard according to DIN EN ISO 13857.
• The belt tension should be checked the blower has been
running for approx. 2 hours. If necessary, retension the
belts (also refer to 5.4).
• Do not put the blower into operation if no protective
grating or equivalent belt guard is attached and securely
bolted in place. (risk of injury).
1.14 Electrical hazards
Danger!
Danger from electric current!
Live components carry current and cause fatal
injuries!
Deactivate the device before opening it, reaching
into it or inserting tools into it; check that compo-
nents are not live and secure it against reactiva-
tion.
2 INFORMATION ON TRANSPORT,
HANDLNG AND STORAGE OF THE
MACHINE
2.1 Transportation and handling
• Before installation and putting into service, check all parts
for transit damage. A damaged blower is a potential safety
hazard and, therefore, should not be put into service.
• Do not leave the blower unprotected in the open
(protect against ingress of moisture).
• Attach hoisting gear securely. Only use hoists and load
suspension devices with su
ffi
cient load-carrying capacity.
Secure the route of transportation.
Note!
The eye bolt on the motor must not be used to lift
the entire blower. This is used if the motor needs
to be (dis-)assembled.
Note!
On devices with in-built frequency converters
(FUK devices):
The frequency converter must never be used to
lift the device or as a climbing aid!
2.2 Storage
• Ensure that the air intake connection and pressure connec-
tion are closed.
• Store the blower
-> in its original packaging if possible
-> in a closed room
-> in a dry, dust-free and vibration-free area.
• Storage temperature range from -20°C to +60°C
• After a storage period of 6 months, the blower bearings
and/or motor bearings should be checked before they are
mounted in the blower.
• Devices may be stored for a maximum of 2 years.
3 INFORMATION ON COMMISSIONING
THE MACHINE
3.1 Basic information
• Prior to the
fi
rst start-up and before any other start-up, the
proper operating status of the unit must be inspected. Units
that, for example, are found to be defective upon delivery
or during installation, must be examined by quali
fi
ed techni-
cians.
• Installation, assembly and operation must only be performed
by properly trained and quali
fi
ed specialists. Operation fol-
lowing incorrect installation, maintenance or unapproved
replacement of components constitutes non-designated use
and renders the warranty void. The resultant risk shall be
borne solely by the customer or owner.
3.2 Installation and assembly
• Protect the blower from the weather and install it in a
horizontal position, see also 1.1. For outdoor use, protec-
tion from the weather must generally be provided that
ful
fi
ls the requirements listed in 1.1 Intended Use and
protects the blower from the in
fl
uences of the weather.
• Do not subject the blower subsequently to vibration or
impact loads during operation. Permissible vibrational load
on blower: refer to ISO 14694, BV-3.
Measurement at the
fl
ange bearing shield, preferably
near the bearing
