In normal operation the electropump does not require any kind of maintenance.
It is recommended to have the system overhauled every 6 months by a
specialised technician.
In the event of long periods of inactivity it is recommended to start up the pump 2
or 3 times a month.
If a join is to be made in the electric cable, use a cable with an adequate section.
It is not possible to carry out any work on the motors since they are made
impermeable by the manufacturer.
