6. 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.
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.
