1.6 Suction effect
The side channel blowers produce a powerful suction effect.
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
operation.
The side channel blower must not be operated
with an open intake opening. The intake opening
must be covered with protective grating according
to DIN EN ISO 13857.
Never place your hands in the intake opening.
1.7 Blowing effect
Warning!
The blowing effect is very powerful on the exhaust
side. Sucked in objects may be ejected at very
high speed (danger of injury).
The side channel 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 before entering into the side channel
blower by installing a filter. Do not reach into the
exhaust.
1.8 Temperature
Warning!
The blower housing heats up during operation.
If the temperature rises above +50 °C, the side
channel blower
operating company against direct contact (risk of
burning!).
1.9 Motor circuit breaker
Before putting the side channel blower into operation, be sure to
safeguard the drive motor with a motor circuit-breaker (this does
not apply to frequency-converter-operated appliances).
Where appliances are
existing temperature sensor (PTC resistor sensor) must be
connected to the converter and evaluated.
1.10 Noise emission
The noise generated by a side channel blower is not constant
throughout the performance range. For details of radiated noise
level, please refer to the table on page 11.
In some cases, sound insulation may be necessary (it is
recommended that emission levels be measured by the
operator). Sound insulation must be provided by the operator to
avoid exceeding the statutory maximum levels at the workplace
and in the immediate vicinity of the side channel blower.
No sound insulation of any kind whatsoever should cause the
ambient temperature to exceed +60°C at the drive motor (this is
not permissible).

must be protected by
frequency-converter-operated,
1.11 V-belt drive (only applies to side channel blower
without motor)
Note!
The side channel 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 using
the calculation method specifi ed by the belt
manufacturer.
The blower belt pulley must not be modified.
The max. permissible compressor speed must not be
•
exceeded (see table on page 11).
The belt drive and freely rotating parts must be
•
covered with belt guard according to DIN EN ISO
13857.
The belt tension should be checked after the blower
•
has been running for approx. 2 hours. The belts must
be retensioned if necessary.
Belt tension: see table on page 11.
•
Never put the side channel blower into operation if the
•
protective grating is not installed and firmly screwed
on (risk of injury).
1.12 Electrical hazards
Before carrying out electrical work, the appliance must always be
switched off and protected against accidental restarting.
Check that no voltage is present.

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 side channel
blower is a potential safety hazard and, therefore,
should not be put into service.
Do not leave the side channel blower unprotected in
•
the
the open (protect against ingress of moisture).
Attach hoist securely. Only use hoists and load
•
suspension devices with suffi cient load-carrying
capacity. Secure the route of transportation.
3. INFORMATION ON COMMISSIONING
THE MACHINE
the
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 qualifi ed technicians.
Installation, assembly and operation must only be
•
performed
specialists. Operation following incorrect installation,
maintenance
components constitutes non-designated use and
renders the warranty void. The resultant risk shall be
borne solely by the customer or owner.
