• Maintenance tasks: The technician must be familiar with the use of operating fluids and
their disposal.
• Electrical work: Electrical work must be performed by a qualified electrician.
• Installation/dismantling work: The installation/dismantling must be carried out by a
qualified technician who is trained in the use of the necessary tools and fixation materi-
als.
It is recommended to have the pump serviced and checked by the Wilo customer service.
DANGER
Risk of fatal injury due to electrical current!
Improper conduct when carrying out electrical work can lead to death
due to electric shock!
• Any work on electrical devices may only be carried out by a qualified
electrician.
• Before carrying out any work, disconnect the unit from the power
supply and secure it against accidental switch-on.
• Any damage to the pump connection cable should only ever be recti-
fied by a qualified electrician.
• Never poke around in the openings of the motor or electronic module
or insert anything into them.
• Follow the installation and operating instructions for the pump, level
control device and other accessories.
• After completing the work, refit previously dismantled protective
devices, for example, covers or coupling covers.
DANGER
When dismantled, the permanent magnet rotor inside the pump can pose
mortal danger for people with medical implants (e.g. pacemakers).
• Follow the general behavioural guidelines that apply to handling elec-
trical devices!
• Do not open the motor!
• Dismantling and installation of the rotor may only be carried out by
Wilo customer service! If you have been fitted with a pacemaker, you
must not carry out this kind of work!
NOTICE
The magnets inside the motor do not pose a danger provided the motor
is completely assembled. Persons with pacemakers can approach the
pump without restrictions.
WARNING
Personal injury due to strong magnetic forces!
Opening the motor leads to high, abruptly occurring magnetic forces.
This can lead to serious cuts, crushing injuries and bruises.
• Do not open the motor!
• Only allow Wilo customer service to dismantle and install the motor
flange and the bearing plate for maintenance and repair work!
