WARNING
Risk of scalding from hot fluids!
The fluid is under high pressure and can be very hot.
Before the installation or removal of the pump or the dismantling of the housing screws, ob-
serve the following:
• Allow the heating system to cool down completely.
• Close shut-off valves or drain the heating system.
• Drain the shut-off branch of the system!
• If no shut-off valves are fitted, drain the system!
• Follow the manufacturer’s instructions and safety data sheets for possible additives in the
system!
Comply with national regulations for accident prevention and also with the operator’s internal work, company
and safety regulations.
WARNING
Risk of injury!
Danger of injury caused by falling motor/pump after loosening the fastening screws!
• Use suitable lifting gear to secure the pump/motor against falling if necessary!
• Wear appropriate protective clothing (e.g. safety gloves)!
DANGER
Risk of fatal injury from magnetic field!
When dismantled, the permanent magnet rotor inside the pump can pose a risk of fatal injury
for people with medical implants (e.g. pacemakers).
• Never remove the rotor.
– If the unit consisting of impeller, bearing plate and rotor is pulled out of the motor, per-
sons with medical aids, such as cardiac pacemakers, insulin pumps, hearing aids, im-
plants or similar are at risk. Death, severe injury and damage to property may be the re-
sult. For such persons, a professional medical assessment is always necessary.
• There is a crushing hazard! When removing the rotor from the motor, it can be pulled back
into its original position by the strong magnetic field.
– If the rotor is outside the motor, magnetic objects may be attracted very suddenly. This
can result in injury and damage to property.
• Electronic devices may be impaired functionally or damaged by the strong magnetic field
of the rotor.
When assembled, the rotor’s magnetic field is guided in the motor’s iron core. However, there is no magnetic
field outside the machine that is harmful to health or has a negative impact.
9.2.1 Dismantling/installation of the motor
Take into account the “Shutdown” chapter before dismantling/installing the motor!
