2. Safety
These instructions contain important information, which must
be followed when installing and operating the pump. These
operating instructions must therefore be read before assembly
and commissioning by the installer and the responsible ope-
rator.
Both the general safety instructions in the "Safety precautions"
section and those in subsequent sections indicated by danger
symbols should be carefully observed.
2.1
Indications used in the operating instructions
Safety precautions in these operating instructions, which, if not
followed, could cause personal injury, are indicated by the sym-
bol:
when warning of electrical voltage with
The following symbol is used to indicate that by ignoring the re-
levant safety instructions, damage could be caused to the
pump/machinery and its functions:
ATTENTION!
2.2
Staff training
The personnel installing the pump must have the appropriate
qualifications for this work.
2.3
Risks incurred by failure to comply with the safety
precautions
Failure to comply with the safety precautions could result in per-
sonal injury or damage to the pump or installation. Failure to
comply with the safety precautions could also invalidate any
claim for damages.
In particular, lack of care may lead to problems such as:
n Failure of important pump or machinery functions,
n Injury resulting from electrical or mechanical factors.
2.4
Safety precautions for the operator
Existing regulations for the prevention of accidents must be fol-
lowed.
Dangers caused by electrical energy must be excluded. Direc-
tives conforming to the local or general regulations [such as

to be observed.
2.5
Safety information for inspection and assembly
The operator is responsible for ensuring that inspection and as-
sembly are carried out by authorised and qualified personnel
who have studied the operating instructions closely.
Work on the pump/machinery should only be carried out when
the machine has been brought to a standstill.
2.6
Unauthorised modification and manufacture of spare
parts
Alterations to the pump or installation may only be carried out
with the manufacturer's consent. The use of original spare parts
and accessories authorised by the manufacturer will ensure sa-
fety. The use of any other parts may invalidate claims invoking
the liability of the manufacturer for any consequences.
2.7
Unauthorised operating methods
The operating safety of the pump or installation supplied can
only be guaranteed if it is used in accordance with paragraph
1 of the operating instructions. The limiting values given in the
catalogue or data sheet must neither be exceeded nor allowed
to fall below those specified.
3. Transport and storage
As soon as the equipment is received, check that it has not been
damaged during transport. If any defect is noted, all the ne-
cessary steps must be taken with regard to the carrier.
If the equipment delivered is to be installed
ATTENTION!
some time later, store it in a dry place and pro-
tect it against impacts and all external effects
(humidity, freezing conditions, etc.).
