1. General
These installation and operating instructions are
an integral part of the product. They must be
kept readily available at the place where the pro-
duct is installed. Strict adherence to these
instructions is a precondition for the proper use
and correct operation of the product.
These installation and operating instructions
conform to the relevant version of the product
and the underlying safety standards valid at the
time of going to press.
1.1 Applications
Pumps aimed at clear liquids in building, agricul-
ture and industry areas...
Water supply - water tower - sprinkling, high
pressure washing - boiler supply - lifting of con-
densates - air conditioning - industrial networks
and integration in all modular systems.
These pumps are suitable for water and other
long viscosity fluids free from mineral oil and
without abrasives or long fibre substances. The
motor-converter being cooled by the liquid flo-
wed by the pump, it is important to validate
beforehand the compatibility of the pump with
the concerned liquid.

tor before the pump is installed or operated.
Both the general safety instructions in this sec-
tion and the more specific safety points in the
following sections should be observer.
2.1 Instruction symbols used in this operating
manual

NOTE : ....
Signal words:
DANGER ! Imminently hazardous situation. Will
result in death or serious injury if not avoided.
WARNING ! Risk of (serious) injury. 'Warning'
implies that failure to comply with the safety
instructions is likely to result in (severe) perso-
nal injury.
CAUTION ! Risk of damage to the
pump/installation. 'Caution' alerts to user to
potential product damage due to non-compli-
ance with the safety instructions.
NOTE ! Useful information on the handling of the
product.
It alerts the user to potential difficulties.
2.2 Personnel qualification
The personnel installing the pump must have the
appropriate qualification for this work.
2.3 Risks incurred by failure to comply with the
safety instructions
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.
In particular, failure to comply with these safety
instructions could give rise, for example, to the
following risks:
• Failure of important pump or system functions,
• Failure of specified maintenance and repair
methods
• Personal injury due to electrical, mechanical and
bacteriological causes.
• Damage to property.
2.4 Safety instructions for the operator
The relevant accident precaution regulations
must be observed.
Potential dangers caused by electrical energy
must be excluded. Local or general regulations
[e.g. IEC, VDE, etc.] and directives from local
