Our technical sales department is available for further advice in these mat-
ters.
Drain the oil (see Chapter 5.4).
Add clean oil until the oil-level is at the “min” mark and let the pump ope-
rate for some time.
Then drain the oil and add clean oil until the oil level is at the “max.” mark.
Seal the connection ports. Special conservation or anti-corrosion oils aren’t
necessary.
Please also take note of the information given in Chapter 7 (Storing the
Pump).
Shutdown through Monitoring Components
When the pump has been switched off due to overheating sensed
by the motor coil protector, the pump must only be started
manually after the pump has cooled down to the ambient tempe-
rature and after having removed the cause first.
Failure of the Control System or the Mains Power
In order to prevent the pump from running up unexpectedly after
a mains power failure, the pump must be integrated in the control
system in such a way that the pump can only be switched on
again manually. This applies equally to emergency cut-out arran-
gements.
