DANGER: Before starting any maintenance and repair
work, disconnect the pump from the power supply, and
make sure it cannot be switched back on by unauthor-
ised persons. Damage to the connection cable should
always be repaired by a qualified electrician. Have faults
remedied by qualified skilled personnel only!
WARNING: Depending on the pump or system operating
conditions (fluid temperature), the entire pump can
become very hot. Touching the pump can cause burns!
When removing the motor head or pump, hot fluid may
spurt out under high pressure. Allow the pump to cool
down beforehand.
Close the stop valves before removing the pump.
Inside the machine there is always a strong magnetic
field that can cause injury and damage to property in the
event of incorrect dismantling.
