5.4 Seals and Radial Shaft Sealing Rings
For safety reasons, sealing elements and radial shaft seals
must be replaced at least in course of every maintenance
work, repair or replacement of parts, which requires that seal-
ing elements are opened, remove or otherwise manipulated.
The equipotential bonding must be inspected in conjunction
with every maintenance job and shall be in good operating
order after the maintenance job is completed. The measures
must not lead to interconnections between explosion protec-
tion zones.
The radial shaft seals must be in perfect condition; this must
be checked during all maintenance work.
5.5 Micro-fi lters
The degree of clogging of the fi lter mats 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.
5.6 ATEX Impeller
The balancing as well as the lateral and radial travel of the
impeller may not be impaired as a consequence of mainte-
nance/service, repair or replacement of parts.
The impeller must be replaced at the latest when clearly de-
tectable vibration occurs, or when mechanical wear or dam-
age is visible.
Use suitable pullers when extracting the impeller. Groves
and fi xing threads are provided on the impeller hub, allow-
ing application of such tools. Install the impeller on the shaft
without impact or jerks.
5.7 ATEX Motors
ATEX motors can only be replaced as complete units. As
required by EN ISO 60079, repair of ATEX motors is exclu-
sively performed by the manufacturer of the motor.
Upon replacement of the motor, ensure exact axial alignment
of all parts connected to or coming in contact with the motor
shaft. Also see 5.7.
5.8 Cleaning/Inspection Opening
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.

Operating and assembly instructions S-MP ATEX
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 infl u-
ence safety or health protection and, for example, impair the
balanced state of the impeller.
When starting up the 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.
5.9 Repair and Replacement of Parts of Elektror ATEX
Products
When using spare parts and accessories for explosion pro-
tected blowers made by Elektror, be sure to apply and ad-
here to the EU regulations or applicable national regulations
for explosion protection. Within the territory of the Federal
Republic of Germany, these especially include the require-
ments set forth in TRBS 1201-3 and §14 (6) of the BetrSichV.
Within the EU, all member states have set in force corre-
sponding legal requirements and regulations which must be
adhered to.
Outside the European Union, the buyer, distributor and user
must adhere to the laws, regulations and statutes relating to
explosion protection, applicable at the operating site of the
respective Elektror ATEX product.

pair or replacement of parts. Please inquire with our Product
management (support@elektror.com) for possibilities in your
country.
These service partners are bound by a contract with Elektror
and have been trained to service our ATEX blowers. Careful
adherence to the ATEX regulations applicable throughout the
EU, but also to the specifi c requirements we have defi ned as
the manufacturer to enhance the safety of our ATEX prod-
ucts, is guaranteed by our service partners.
Deviations from the procedures required to maintain safety
and health protection or explosion protection on the part of
the customer may lead to loss of warranty and exclusion of
liability by Elektror.
As specifi ed by law, the user is responsible for safety and
health protection during operation as well as for trouble-free
operation.
According to the ATEX directive for explosion protection as
well as the regulations and standards based on it, require-
ments detailing admissible and inadmissible material com-
binations have been published. Inadmissible material com-
binations may render ineff ective any constructive measures
aimed at achieving explosion protection. This may substan-
tially increase the explosion risk entailed in ATEX products.
Spare parts list of non-explosion-protected devices must not
be applied to ATEX appliances and are therefore void.
Recommendation: Use only original spare parts provided by
Elektror as this will enable low-risk replacement.
