2.2 Notes on safety for the cus-
tomer / operator
The following must be observed:
♦
The notes on safety contained in this operating
manual,
♦
the prevailing regulations on accident prevention,
♦
in-house work, operating and safety regulations of
the customer.
♦
Hot or cold machine parts must be protected by the
customer against being touched.
♦
Do not remove any protective facilities when the
machine is in operation.
♦
Hazards due to electricity are to be excluded.
♦
Leaks of hazardous media (e.g. explosive, toxic,
hot) must be removed so that no risk arises for peo-
ple and the environment. Legal regulations must be
observed.
Caution when using the units in potentially
explosive area!
Prevent inadmissible modes of operation.
2.3 Notes on safety for mainte-
nance
In principle, work on the unit may only be performed
when it is at a standstill.
It is imperative to observe the procedure for stopping
the machine described in this operating manual. See
Section 6.3 .
Pumps which convey media which are a health hazard
must be decontaminated.
Immediately after completion of the work, re-install all
safety and protective facilities or put them into opera-
tion again.
In the assemble state, if the safety notes (see also Sec-
tion 5.1 and 7.5.2 ) are observed, the magnetic drives
do not cause any risks or have any affect on the envi-
ronment.
It is imperative to observe the notes on
safety in
Section 7.5.2 during disman-
tling and assembly as well as during
transport and storage of magnetic drives
as single components.
The points listed in Section 6.1 must be followed
before recommissioning.
2.4 Conversion work and produc-
tion of spare parts by the cus-
tomer
Conversion of or changes to the machine are only ad-
missible after consultation with the manufacturer.
Original spare parts and accessories authorised by the
manufacturer serve to enhance safety.
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 ex-
plosion 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 guarantee 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 rec-
ommend that appropriate monitoring facil-
ities be provided.
All auxiliary, heating and cooling systems
must also be carefully filled.
