Installation and operating instructions Wilo-Stratos MAXO/-D/-Z
Maintenance
WARNING
Risk of burns!
Incorrect dismantling/installation can lead to injuries and damage to property.
Depending on the operating status of the pump and system (temperature of the
fluid), the entire pump can get hot.
Risk of burns if the pump is touched!
▪ Allow the system and pump to cool to room temperature!
WARNING
Risk of scalding!
The fluid is under high pressure and can be hot.
There is a risk of scalding due to escaping hot fluid!
▪ Close shut-off devices on both sides of the pump!
▪ Allow the system and pump to cool to room temperature!
▪ Drain the shut-off branch of the system!
▪ If no shut-off devices are fitted, drain the system!
▪ Follow the manufacturer's instructions and safety data sheets for possible additives in
the system!
WARNING

Danger of injury!

Danger of injury caused by falling motor/pump after loosening the fastening screws.
▪ Comply with national regulations for accident prevention and also with the operator's
internal work, company and safety regulations. If necessary, wear protective clothing
and equipment!
DANGER
Risk of fatal injury!
The permanent magnet rotor inside the pump can be a danger to life for people with
medical implants during dismantling.
▪ Removal of rotor from the motor housing is permissible only for authorised and quali-
fied personnel!
▪ 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
may cause bodily injury and material damage!
▪ Electronic devices can be impaired or damaged by the strong magnetic field of the ro-
tor!
In assembled condition, 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 af-
fects the machine.
Take into account the "Shutdown" section before dismantling/installing the motor!
DANGER
Risk of fatal electrical shock! Generator or turbine operation during
pump flow!
Even without the module (without electrical connection), there may be dangerous
contact voltage at the motor contacts.
