1.5 GENERAL SAFETY INFORMATION
Do not service, install or move the electropump while it is powered, because these operations can cause serious
accidents or even death.
DANGER
Before repairing or servicing the electropump, disconnect it from the socket and/or turn the main switch to Off (when
present) to interrupt the power supplied to the electropump. This prevents the electropump from accidentally restarting
and from causing accidents to people and/or damages to the people.
DANGER
Before using the electropump, always check that the cable and all electric devices are efficient, shielded and protected.
When starting the electropump (by inserting the plug into the socket and/or turning the main switch to on), always wear
shoes and make sure that the hands are dry.
DANGER
It is advisable to carefully follow the instructions contained in this manual with specific reference to notes, warnings and danger
signs.
During operation, do not remove or move the electropump.
