Remove leaks of hazardous media (e.g. explosive,
toxic, hot) so that there is no risk to people and the
environment. Observe statutory regulations.
Provide and use protective equipment for the staff.
Caution when using the units in potentially
explosive area!
Prevent inadmissible modes of operation.
2.3 Notes on safety for
maintenance
Strictly, work on the pump/unit may only be
performed when it is at a standstill.
The pump housing must have reached ambient
temperature.
The pump housing must be depressurized and
drained.
It is imperative to observe the procedure for
stopping the machine described in this operating
manual. See also Section 6.3.
Decontaminate pumps which convey media
hazardous to health.
Immediately after completion of the work, re-install
all safety and protective facilities or put them into
operation again.
When installed, the magnetic drives do not
represent any risk of environmental impact if the
notes on safety are observed (see also Sections
5.1 and 7.5.2).
It is imperative to observe the notes on
safety in Section 7.5.2 during dismantling
and assembly as well as during transport
and storage of magnetic drives as single
components.
Observe the points listed in Section 6.1 prior to
recommissioning.
2.4 Conversion work and
production of spare parts by
the customer
Conversion of or changes to the machine are only
admissible
after consultation with the
manufacturer.
Only use original spare parts or parts approved by
the manufacturer.
The use of other parts may annul the liability for
any resultant consequences.
2.5 Improper operation
The operational safety of the machine supplied is
only guaranteed if it is used properly in accordance
with Section 2.1 of this operating manual.
The operating limits specified in the data sheet
must under no circumstances be exceeded.
2.6 Special requirements for
explosion protection
If the units are used in potentially explosive areas, the
measures and notes in Sections 2.6.1 to 2.6.9 are
imperative to observe the explosion protection.
2.6.1 Filling the unit
During pump operation the wetted interior of
the pump must always be filled with the liquid
medium.
This prevents any explosive atmosphere and the risk
of dry-running.
If the customer cannot ensure this, we
recommend that appropriate monitoring
facilities be provided.
Also carefully fill auxiliary, heating and cooling
systems.
