10.02 Dismantling and disposal
Dismantling - Disassembly
Before starting dismantling, the air heater or the consumers installed in it must be disconnected from the power supply.
All current-carrying connection lines must be removed by a qualified electrician.
Dismantling may only be carried out by qualified personnel. The qualified personnel are obliged to comply with the
general accident prevention regulations (e.g. UVV in Germany) and to wear the necessary personal protective equip-
ment (e.g. breathing mask, protective goggles, protective clothing).
Furthermore, all media-carrying components must be completely drained. This must be carried out by a specialist com-
pany that carries out a professional disposal of water with antifreeze.
After this, the air heater can be disassembled on site into the individual units or into its individual parts. This should
also be carried out by a specialist company that is familiar with the environmentally friendly disposal of the individual
parts.
Suitable personal protective equipment must be worn when handling dusty / dirty components.
Disposal must be carried out in accordance with the valid, relevant and local environmental and recycling regulations
of your country and municipality.
