CAUTION!
Danger of damage due to incorrect
packaging! If the pump is transported again later
on, it must be well packed to avoid any damage
during transport.
• Use the original packaging for this, or select a sim-
ilar packaging
.
WARNING!
Danger of personal injury!
Inadequate transport can lead to personal injury!
• The pump must be transported using approved
load bearing equipments. Operate a slinging on
the pump flanges and, if necessary, on the outer
motor diameter (safety device required to protect
against slipping!).
• Due to high position of the centre of gravity and
small ground surface of this type of pumps,
beware of unstability during handling to avoid any
falling down that may cause a risk for the safety of
the persons
.
Handle the pump carefully so as not to alter the
goemetry and the alignment of the unit.
CAUTION!
Danger of damage for the pump!
The transport eyes on the motor should only be
used for transporting the motorconverter,
and are not approved for transporting the com-
plete pump.
