Packaging information
Materials used for packaging are environmentally compatible.
They can be safely deposited or they can be burnt in an incinerator.
Recycling
Cardboard: Can recycle up to 99% and therefore should be put into
the waste collection system.
Polyethylene: Can be recycled.
When the HM 1500 / HC 2500 has completed its working life, it must
be thoroughly cleaned. The synthetic fittings can be incinerated.
The printed circuit boards and metallic parts can be scrapped.
