12. DISPOSAL

When discontinuing operation, the pressure booster set, or any

of its components, must be disposed of in a separated manner
according to what is set forth by the regulations in force in the
country where the set is installed.
For components such as the pump inverter panels and
pressure switches, see the specific component manuals

In particular, this symbol on the product indicates that it cannot

be disposed of together with domestic waste. This provision
concerns only the disposal of equipment in the territory of the
European Union (2012/19 EU).

Note: “Lm” ferrite application (E-SPD MV models)

For single-phase models (E-SPD MV), the ferrite is positioned close to the inverter, encasing the power cable, as shown in the
inverter's specific instruction manual.

Note: “Lt” ferrite application (E-SPD TT models)

For three-phase models (E-SPD TT), the ferrite is positioned encasing the 4 motor power connecting cables, therefore close
to the “MOTOR OUTPUT” terminal block of the inverter internal board.
