WARNING
Electric shock
Death or serious personal injury
‐ If the product is used for cleaning or maintenance of
garden ponds or similar places, make sure that the
product is supplied through a GFCI (ground fault circuit
interrupter) with a rated residual operating current not
exceeding 6 mA.
All electrical connections must be carried out by qualified
persons in accordance with local regulations.
Make sure that the electrical installation supports the rated
current [A] of the product. See the product's nameplate.
4.3.1 Motor protection
The pump incorporates current- and temperature-dependent motor
protection. If the pump is running without water, is blocked or
otherwise overloaded, the built-in thermal switch will cut out. When
the motor has cooled sufficiently, it will restart automatically.
No external motor protection is required.
4.3.2 Connecting to the power supply
WARNING
Electric shock
Death or serious personal injury
‐ Disconnect the main switch prior to electrical work.
