Dismounting
DANGER
Danger to life and material damage due to magnetic field!
Make sure that personnel with pacemakers do not com-
plete work on the pump.
Secure the work place and if necessary cordon off:
–
Make sure that personnel with pacemakers keep a safe
distance of > 1 m.
–
Make sure that no magnetizable metal parts can be
attracted by the pump's magnetic coupling.
–
Make sure that parts of the magnetic coupling cannot
be attracted by the magnetizable metal parts.
Maintain a safe distance of at least 150 mm from the mag-
netic coupling for magnetically sensitive objects.
DANGER
Risk of injury due to running pump!
Do not touch the pump when it is running.
Do not carry out any work on the pump when it is running.
Before all installation and maintenance work, disconnect
the motor from the mains and secure it against being
switched back on again.
DANGER
Risk of electrocution!
All electrical work must be carried out only by qualified elec-
tricians.
Before all work on the electrical system, disconnect the
motor from the mains and secure against being switched
back on again.
WARNING
Risk of injury and poisoning due to hazardous or hot fluid!
Use personal protective equipment when carrying out any
work on the pump.
Allow the pump to cool completely before commencing any
work.
Make sure the pump is depressurized.
Empty the pump, safely collect the pumped liquid and dam-
age it in accordance with environmental rules and require-
