5.2 Ball Bearings
Danger!
EN
Risk of injury and property damage posed by
improper handling!
The risk of injury and property damage increases
considerably if the device is handled incorrectly.
Explosions and the property damage and phy-
sical injuries resulting from them are the conse-
quence.
Only authorised specialist workshops with
approval are allowed to perform repairs to ATEX
devices.
Note!
The ball bearings are to be checked during each
instance of service and prior to each instance of
commissioning.
Operation is only permitted with fl awless ball
bearings!
Refer to the supplier's documentation of the
ATEX motor manufacturer for further notes.
Note!
In the event of frequently starting up and shutting
down, premature replacement of the bearings
will be required. Determining the time for repla-
cing the bearings is the sole responsibility of the
maintenance and servicing personnel, who must
make a safety judgement.

5.3 Seals and Radial Shaft Sealing Rings
Sealing components and radial shaft sealing rings should be
replaced for safety reasons at least at every maintenance
and when components are repaired and replaced if the seal-
ing elements are opened, removed or changed in any other
way. The potential equalisation must be checked at every
maintenance and be in a good condition when this is com-
pleted. There must then be no zone entrainment, for exam-
ple, as a result of the measures taken.
The condition of the radial shaft sealing rings should be
checked at every maintenance at least and be in an impec-
cable condition.

5.4 Fine fi lters
The extent of contamination on the fi lter mats should be
checked at regular intervals depending on the operating/am-
bient conditions and the environmental protection guidelines
if necessary. i.e. the permeability of the fi lters must be guar-
anteed by the machine operator.
5.5 ATEX Impeller
The balance state as well as the axial and radial run-out of
the impeller must not deteriorate as a result of the mainte-
nance/servicing, repair or replacement of components.
The impeller should be replaced at the latest when there are
clearly discernible vibrations/oscillations or signifi cant me-
chanical wear or damage is detected.
Use a suitable tool to remove the impeller. There are grooves
or a fi xing thread on the impeller hub for a tool of this kind.
The impeller must be fi tted to the shaft without it experienc-
ing any knocks or bumps.
5.6 ATEX Motors
ATEX motors can only be replaced as complete units. Re-
pairs to the ATEX motors used must be carried out exclu-
sively by the manufacturer themselves in accordance with
EN ISO 60079.
5.7 Cleaning
Cleaning or maintenance must not lead to damage or modi-
fi cations to the device and its components that would infl u-
ence safety or health protection and, for example, impair the
balanced state of the impeller.
No agents/tools are to be used for cleaning purposes that
may lead to an electrostatic charge or any other type of safe-
ty hazard.
5.8 Repair and Replacement of Components on Elektror
ATEX Products
When using spare or accessory parts for our explosion-proof
blowers, we draw your attention to the regulations within the
EU or the appropriate national regulations, which must be
strictly observed. These are in particular the requirements
of the TRBS 1201-3 and §14 (6) of the German Ordinance
on Industrial Safety and Health (BetrSichV) in the territory of
the Federal Republic of Germany. Relevant guidelines and
provisions corresponding to these regulations, which must
be observed on an equal footing, apply in all member states
in the EU.
Outside the European Union, customers, distributors and
machine operators must comply with the laws, regulations
and statutory provisions that are applicable at the location
at which the respective Elektror ATEX product is operated.
