6 Maintenance/faults
DANGER: Before starting any maintenance and repair
work, disconnect the pump from the power supply, and
make sure it cannot be switched back on by unauthor-
ised persons. Damage to the connection cable should
always be repaired by a qualified electrician. Have faults
remedied by qualified skilled personnel only!
WARNING: Depending on the pump or system operating
conditions (fluid temperature), the entire pump can
become very hot. Touching the pump can cause burns!
When removing the motor head or pump, hot fluid may
spurt out under high pressure. Allow the pump to cool
down beforehand.
Close the stop valves before removing the pump.
Inside the machine there is always a strong magnetic
field that can cause injury and damage to property in the
event of incorrect dismantling.
• It is only permitted to have the rotor removed from the
motor housing by qualified personnel.
• If the unit consisting of impeller, bearing shield and
rotor is pulled out of the motor, persons with medical
aids, such as cardiac pacemakers, insulin pumps, hear-
ing aids, implants or similar are at risk. Death, severe
injury and damage to property may be the result. For
such persons, a professional medical assessment is
always necessary.
In assembled condition, the rotor's magnetic field is guided
in the motor's iron core. There is therefore no harmful mag-
netic field outside the machine.
