1.6 Suction eff ect
The blowers produce a powerful suction eff ect.
Warning!
Objects, items of clothing and also hair can be
sucked into the intake port. Risk of injury!
Do not stand near the intake opening during op-
eration. The blower must not under any circum-
stances be operated with the intake port open,
and should, therefore, be covered with a wire
guard in conformity with DIN EN ISO 13857
1.7 Blowing eff ect
Warning!
The blowing eff ect is very powerful on the ex-
haust side. Sucked in objects may be ejected at
very high speed (danger of injury).
The blowers are designed for delivery of clean
air only. To reliably prevent the sucking-in of
foreign objects or contaminants, which might be
discharged, these objects have to be removed be-
fore entering into the blower by installing a fi lter.
Do not reach into the exhaust.
1.8 Temperature
Warning!
The blower housing assumes the temperature
of the conveyed medium during operation. If the
temperature of the conveyed medium is above
+50°C, the blower must be protected against
direct contact by the operator
(risk of burn injury).
There may be an increase in the temperature of the medi-
um to be conveyed, particularly with higher pressure mod-
els, when conveying the medium from the air intake side to
the discharge side. The discharge temperatures can rise to
+80°C depending on the operating conditions and tempera-
ture of the medium to be conveyed.
1.9 Motor circuit breaker
For devices operated with a frequency converter, the exist-
ing temperature sensor (PTC resistor sensor) or temperature
gauge (break contact) should be connected and analysed on
the converter.

1.10 Noise emission
Minimum fre-
Note!
quency
Wear hearing protection during operation at a
daily exposure level of 80 dB(A) and above, and/
or a peak sound pressure level of 135 dB(C) and
20 Hz
above.
Failure to do so may cause hearing damage.
The noise generated by a blower is not constant throughout
the performance range. For details of noise emission levels,
please refer to the chapter 9 "Technical Specifi cations".
In some cases, sound insulation may be necessary (it is rec-
ommended that emission levels be measured by the opera-
tor). Sound insulation must be provided by the operator to
avoid exceeding the statutory maximum levels at the work-
place and in the immediate vicinity of the blower.
No sound insulation of any kind whatsoever should cause
the ambient temperature to exceed +40°C at the drive motor
(this is not permissible).
1.11 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 TRANSPORTATION
AND HANDLING 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 suffi cient load-carrying capacity.
Secure the route of transportation.
Note!
The eye bolt on the motor should not be used to
lift the whole blower. This is used for (dis-)assem-
bling of the motor.
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 -10°C to +60°C
• After a storage period of 6 months, the blower bearings and
motor bearings should be checked before they are mounted
in the blower.
• Devices may be stored for a maximum of 2 years.
