If continued operation or repair should not appear advisable,
we will offer a new appliance suitable for your application.
In Germany and diverse other European countries you may
alternatively avail yourself or our service contractors for re-
pair or replacement of parts. Please inquire with our Cus-
tomer Support (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.
Delivery of spare parts
When ordering spare parts, please always state the serial
number of the respective Elektror ATEX product. You will fi nd
it on the nameplate attached to the blower housing.
Note!
When ordering please state:
Unit no. (nameplate)
Unit type (nameplate)
Housing positions
The position of the blower housing is important for ordering
several spare parts. Determine the position of your blower by
looking at the intake end. Order spare parts which match the
direction of rotation.

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 ineffective 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.
5.2 Basic information
Before and after maintenance/service measures, repairs or
replacement of parts, an Elektror ATEX blower may only be
employed as intended (see 1.1).
Before commencing with the maintenance/service measure,
repair or replacement of parts ensure that the blower impel-
ler has stopped and the blower has been secured reliably to

prevent start-up. For instance, electric power supply to the
blower must be interrupted, ideally by separation at the ter-
minals.
At no point during maintenance, cleaning, service or repair
may an explosion hazard exist or arise.
Wear parts are subject to the recommend maintenance in-
tervals (see 5.3 to 5.9 ). The service life of wearing parts
(ball bearings and fi lters) depends on the operating hours,
the load and other infl uences, such as temperature, etc.
Accessibility for regular maintenance must be ensured.
Maintenance and servicing may only be performed by per-
sons with the necessary expertise and regular training. In ad-
dition to the appliance's operating instructions and the regu-
lations and recommendations for the system as a whole, the
following points should be observed:

5.3 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!
We recommend to have repairs carried out by the
manufacturer. We cannot accept any liability for
repairs carried out by third parties.
Perform the following tasks in course of every inspec-
tion/maintenance job as well as upon repair and replace-
ment of parts:
• Visually inspect all movable parts of the blower, such as
impeller, blower housing cover / intake nozzle for possible
damage, scoring, wear, fi ssures, cracks, deformation;
proper condition of all earthing connections, radial shaft
seals etc.
• Inspect the gap between the impeller nozzle and the intake
nozzle at the blower cover.
All S-MP ATEX machine types:
Minimum gap 2.0 mm
• If ATEX blowers are stored for replacement, note that some
components installed have a limited storage life. This espe-
cially applies to the ball bearings, e.g. concerning the life of
the grease lubrication. The storage life depends on the type
of storage and the unit type as well as on the conditions and
duration of storage of the Elektror product. Type-related in-
formation can be acquired from Elektror Customer Support.
• Inspection and service work must be documented chrono-
logically and fully stating the name of the person responsi-
ble. In particular, operating errors, measures implemented
as well as compliance with all applicable regulations and the
manufacturer's specifi cations must be documented. It is rec-
ommended that this documentation be kept in a report book
and safely stored.

5.4 Ball Bearings

Bearing life: The information provided by the manufacturer of
the ATEX motor exclusively applies (also refer to 5.8).
The ball bearings must be in perfect condition; this must be
checked during all maintenance work.
Note!
Information concerning the achievable hours of
operation refers to the rated speed and intended
use, excluding frequent start-up and shutdown.
Depending upon performance, earlier replace-
ment of bearings and radial shaft seals may be
necessary.
