DANGER! Risk of fatal injury!
Incorrect installation and improper electrical connections can
result in fatal injury.
• Have the electrical connections established by approved electri-
cians only, in compliance with the applicable regulations.
• Accident prevention regulations must be observed.
DANGER! Risk of fatal injury!
Failure to install safety devices on the module cover or near the
coupling can cause electrical shock or contact with rotating parts,
potentially resulting in life-threatening injuries.
WARNING! Risk of injury due to the weight of the pump!
The pump itself and the parts of pump can be extremely heavy.
Falling parts pose a risk of cuts, crush injuries, bruises or impacts,
which may lead to death.
• Always use suitable lifting equipment and secure parts against fall-
ing.
• Never stand underneath a suspended load.
CAUTION! Risk of damage!
Danger of damage due to incorrect handling.
• Have the pump installed by qualified personnel only.
CAUTION! Damage to the pump due to overheating!
The pump must not be allowed to operate dry for more than
1 minute. Dry running causes a build-up of energy in the pump,
which can damage the shaft, impeller, and mechanical seal.
• A minimum flow of approximately 10% of the maximum flow rate
must be ensured at all times.
The motor terminal box must not face downward. If necessary, the
motor or motor impeller unit can be rotated once the hexagon head
bolts have been loosened.
• The pump should only be installed after completion of all welding and
soldering work and, if necessary, flushing of the pipe system. Dirt can
cause pump failure.
• Standard pumps must be protected from the weather and installed in
a frost/dust-free, well-ventilated environment which is not poten-
tially explosive.
• Install the pump in a place that is easy to access so that subsequent
inspections, maintenance (e.g. mechanical seal) or replacement is
easily possible.
• A hook or a lug with sufficient load-bearing capacity must be installed
vertically over the pump (total weight of the pump: see catalogue/
data sheet). This is to allow hoisting gear or similar aids to be attached
to the pump during maintenance or repair work.
CAUTION! Risk of damage!
Danger of damage due to incorrect handling.
• Only use lifting eyes on the motor for carrying the weight of the
motor and not for carrying the entire pump.
• Lift the pump using permitted load-bearing equipment (see chap-
ter 3 "Transport and interim storage" on page 24.
• Minimum axial distance between a wall and the fan cover of the
motor: Free dismantling dimension of at least 200 mm + diameter
of the fan cover.
