Warning
The electrical installation must be carried
out by an authorised person in accordance
with local regulations.
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.
Caution
Do not start the pump until it has been
filled with liquid.
Caution
If a dry-running alarm has been activated,
find the cause before the pump is restarted
in order to prevent damage to the pump.
Note
In case of a very small consumption, the
anti-cycling function may detect this as
cycling and stop the pump inadvertently. If
this occurs, the function can be disabled.
Caution
Set auto reset to "on" only if there is
positive inlet pressure.
