Malfunctions
Please note the following instructions should the pump malfunction:
DANGER
Strong magnetic field in the vicinity of the drive system!
Danger to life for persons with cardiac pacemakers when the drive system is disas-
sembled.
Î
Persons with cardiac pacemakers must not enter the area of the magnetic field.
Î
Disassembled magnetic couplings must be kept away from computers, data storage
media and other electronic components.
CAUTION
Hot surface!
Danger of burns if hot parts are touched. The surface temperature of the pump may
rise above 105 °C in case of malfunction.
Î
Carry out work on the pump only after it has cooled to a safe temperature.
NOTE
Motor overload!
Depending on the malfunction (e.g. blocking during cold start), the motor may not be
sufficiently protected by the built-in thermal protection switch from damage through
overheating.
Î
Implement an additional network safety device.
