11. Megging Megging of an installation incorporating a GRUNDFOS MAGNA pump is not allowed, as the built-in electronics may be damaged. If megging of Warning the pump is necessary, the pump should be electrically separated from the installation. Before removing the cables, the electricity must be switched off.
13. Disposal This product or parts of it must be disposed of in an environmentally sound way: 1. Use the public or private waste collection service. 2. If this is not possible, contact the nearest Grundfos company or service workshop.
