13. Disposing of the product
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.
3. Dispose of the waste battery through the national collective schemes. If in doubt, contact your local Grundfos company.
The crossed-out wheelie bin symbol on a product means that it must be disposed of separately from household waste. When a
product marked with this symbol reaches its end of life, take it to a collection point designated by the local waste disposal
authorities. The separate collection and recycling of such products will help protect the environment and human health.
