2.3 Risks incurred by failure to comply with the safety precautions
Failure to comply with the safety precautions could result in personal injury or damage
to the pump or installation. Failure to comply with the safety precautions could also
invalidate any claims for damages.
In particular, lack of care may lead to problems such as:

Personal injury due to electrical, mechanical and bacteriological causes.
Damage to property.
2.4 Safety precautions for the operator
Existing regulations for the prevention of a ccidents must be followed.
Dangers caused by electrical energy are to be excluded. Directives issued by the local

2.5 Safety information for inspection and assembly
The operator must ensure that all inspection and installation work is carried out by
authorised and qualified specialists who have carefully studied these instructions.
Work on the pump/machinery should only be carried out when the machine has been
brought to a standstill.
2.6 Unauthorized modification and manufacture of spare parts
Alterations to the pump or installation may only be carried out with the m anufacturer's
consent. The use of original spare parts and accessories authorised by the
manufacturer will ensure safety. The use of any other parts may invalidate claims
invoking the liability of the manufacturer for any consequences.
2.7 Unauthorized 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.
