Operating and assembly instructions S-MP-ATEX
We recommend ball bearings are replaced every two years.
The time when the ball bearings will need replacing depends
on operating conditions and might be later, but could also
be much sooner, than this. The operating fi rm bears sole re-
sponsibility for safe judgement of when replacement is nec-
EN
essary.
5.5 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.
5.6 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.
5.7 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.
5.8 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
22
shaft. Also see 5.7.
5.9 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.
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.
