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 dis-
posed 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.
See also end-of-life information at
recycling.
