MAINTENANCE
Cleaning and maintenance activities must not be carried out by children (under 8 years of
age) without supervision by a qualified adult. Before starting any work on the system or
troubleshooting, it is necessary to interrupt the electrical connection of the pump (remove the
plug from the socket) and read the instruction and maintenance manual.
In normal operation the pump does not require any type of maintenance. The pump may not
be disassembled except by qualified and specialised personnel. Any modification
made without prior authorisation relieves the manufacturer of all responsibility.
All repair and maintenance work must be carried out only after having disconnected the pump
from the power supply mains.
It is recommended to have the system serviced every 6 months by a qualified technician.
In case of long periods of inactivity, it is recommended to start the pump 2 or 3 times a month.
If a join has to be made in the power cable, use a cable with a suitable cross section.
Any modification made without prior authorisation relieves the manufacturer of all
responsibility. All the spare parts used in repairs must be authentic and all accessories must
be authorised by the manufacturer, in order to ensure maximum safety of the machines and of
the systems in which they may be installed.
