Warning
Before making any connections in the
unit, make sure that the power supply
has been switched off and that it
cannot be accidentally switched on.
The unit must be connected to an
external mains switch with a contact
gap of at least 3 mm in all poles.
As a precaution, the unit must be
connected to a socket with earth
connection.
We recommend to fit the permanent
installation with an earth leakage
circuit breaker (ELCB) with a tripping
current < 30 mA.
Do not start the pump until it has been
filled with liquid.
If a dry-running alarm has been
activated, find the cause before the
pump is restarted in order to prevent
damage to the pump.
