2. Safety
These instructions contain major information, which must be observed
when installing and operating the pump.
These instructions must therefore be by the installer and the responsi-
ble operator before the pump is installed or started up.
Both the general safety instructions in the «safety precautions» section
and those in subsequent sections indicated by danger symbols should
be carrefully observed.
2.1 Symbols used in the instruction
Safety precaution which if not followed could cause personal injury:
Safety precaution concerning electrical risks which if not followed could
cause personal injury:
Safety precaution which if not followed could cause damages to the
pump or installation and cause it to malfunction:
CAUTION !
Useful hint to give suggestions and helps the work to be carried out:
2.2 Qualified personnel
The personnel installing the pump must have the appropriate qualifica-
tions 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 personal
injury or damage to the pump or installation. Failure to comply with the
safety precautions could also invalidate any claim for damages.

lead, for example, to risks such as :
• Significant failure of the pump or installation.
• Personal injury due to electrical, mechanical or bacteriological causes.
• Damage to property.
2.4 Safety precautions for the operator
Existing regulations for the prevention of accidents must be followed.
Dangers caused by electrical energy (electric shock or electrocution)
are to be excluded. Safety precautions issued by the local electricity
supply company are to be observed.
2.5 Safety precautions for the installation
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 or installation should only be carried out when the
pump is OFF.
2.6 Unauthorized alterations 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 accesso-
ries authorized by the manufacturer will ensure safety. The use of any
other parts may invalidate claims invoking the liability of the manufactu-
rer for any consequences.
2.7 Improper use
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 under no
circumstances be exceeded.
3. Transport and interim storage
When receiving the material, check that there has been no damage
during the transport. If any defect has been stated, take all necessary
steps with the carrier within the allowed time
During transport and in storage the pump must be protected against
moisture, frost and mechanical damage.
Due to high position of centre of gravity and small ground
surface of this type of pumps, beware of instability during
handling to avoid any falling down and take necessary means
to avoid injuries or damaging.
Handle the pump carefully so as not to alter the geometry
and the alignment of the unit.
CAUTION !
