Warranty

The warranty conditions of our German companies do not

apply to appliances acquired outside of Germany. In countries

where our subsidiaries sell our products, it is increasingly the

case that warranties can only be issued by those subsidiaries.

Such warranties are only granted if the subsidiary has issued

its own terms of warranty. No other warranty will be granted.

We shall not provide any warranty for appliances acquired in

countries where we have no subsidiary to sell our products.

This will not aect warranties issued by any importers.

Environment and recycling

We would ask you to help protect the environment. After use,

dispose of the various materials in accordance with national

regulations.
