following points should be observed:
Inspection and maintenance intervals:
The operator must set the cleaning, inspection and mainte-
nance intervals himself according to operating hours, load
and operating conditions.
Immediate inspection and maintenance
The blower must be inspected immediately if vibrations or
reduced air
fl
ow are observed.
Note!
Repairs must be carried out by the manufacturer.
We cannot accept any liability for modi
fi
cations
or the replacement of components carried out by
third parties.
5.1 Ball bearings
The side channel is equipped with enclosed deep groove ball
bearings, which do not have be to re-greased and have a
minimum service life of approx. 22,000 hours. We recom-
mend exchanging the ball bearings before the end of their
service life (at least 22,000 hours).
A service period of 30 months must not be exceeded if the
blower runs continuously for 24 hours a day.
5.2 Seals and radial shaft sealing rings
Sealing elements and shaft sealing rings must, for safety rea-
sons, always be replaced after maintenance work involving
opening, removing or otherwise modifying sealing elements.
5.3 Micro-
fi
lters
The degree of clogging of the
fi
lter elements should be
checked at regular intervals, depending on the ambient
conditions / conditions of use. This means that the user is
responsible for ensuring that the
fi
lters are permeable. The
micro-
fi
lter must be positioned horizontally to prevent con-
tamination entering the side channel blower during mainte-
nance work. With vertical micro-
fi
lter installation, the com-
plete
fi
lter must be removed from the unit before starting
cleaning/maintenance.
5.4 Pressure limiting valve
The pressure limiting valve is a safety valve and its operation
must therefore be checked at regular intervals depending on
application conditions. The operating side must be closed
during inspection. The pressure limiting valve must respond
at the maximum pressure value.
Note!
Repairs must be carried out by the manufacturer.
We cannot accept any liability for modi
fi
cations
or the replacement of components carried out by
third parties.
5.5 V-belt: Information on units without drive motor
intended for operation with a V-belt drive
We recommend that you check the V-belt tension approx.
every 5,000 operating hours. New V-belts must be checked
after a running-in time of 2 hours and re-tensioned if neces-
sary.
For data relevant to the V-belt drive of your unit, please refer
to the speci
fi
cations in the table in Chap. 9 of these Operat-
ing and Assembly instructions.
5.6 Cleaning
There is a high risk of injury on the inside of the device due to
rotating parts during operation. Decommission the device in
all cases and wait until all moving parts have stopped before
opening, reaching in or inserting tools into the device. Secure
the device reliably against it being accidentally restarted dur-
ing the entire period.
Also make sure that no other dangerous situation can arise
when restarting after a standstill, e.g. as a result of a power
failure or blockages.
Cleaning or maintenance must not lead to damage or modi-
fi
cations to the device and its components that would in
fl
u-
ence safety or health protection and, for example, impair the
balanced state of the impeller.
When starting up the side channel blower, make sure that
all tools or other foreign objects have been removed from
inside the device and that all covers and protective grilles
have been attached correctly.
6 SAFETY RELATED INFORMATION
ON TAKING OUT OF OPERATION AND
REMOVAL
The disconnecting of all electrical connections and all oth-
er electrical engineering work in connection with taking the
blower out of operation must be referred to a quali
fi
ed electri-
cian.
The blower may only be dismantled after all rotating parts
have come to a standstill and a safeguard has been provided
to prevent restarting.
Dismantling and removal must be performed in accordance
with the guidelines set out in section 2.1, Transportation and
handling. Dispose of in the appropriate manner.
