DANGER!
Danger of fatal injury from magnetic field!
The strong magnetic field in the vicinity of the
magnetic drive pump can be life-threatening for
people with pacemakers.
Therefore:
– Ensure that people with pacemakers do not
carry out any maintenance work which would
result in dismantling the magnetic coupling
(replacing the pump head, replacing the seal on
the containment can).
NOTICE!
When pumps are fully assembled, the magnetic
fields are shielded completely by the components
which surround them and there is no danger, either
when the pump is idling or in operation.
Necessary equipment
Test control unit for quality control (condition of the pump),
further information under
www.hb-therm.ch
.
NOTICE!
No test control unit is required if there is a built-in
pump wear monitor (ZU).
