Decommissioning; Correct Disposal Procedure For Units With R32 Refrigerant - Mitsubishi Electric MEHP-iB-G07 Installations, Bedienungs Und Wartungsanleitungen

11 DECOMMISSIONING

The WEEE directive 2012/19/EU prohibits disposal of the electrical and electronic equipment of the unit in mixed municipal waste. The following symbol
indicates that the equipment must be separated.
Proper disposal of the electrical and electronic equipment helps reduce the risk of harm to human health and to the environment.
The purchaser, who plays a key role in the reuse, recovery and recycling of this equipment, is invited to contact the local authorities, the waste disposal
service, the retailer or producer to request the necessary information.
When components are replaced, or when the entire unit is removed from the installation at the end of its useful life, the following requirements must be
observed to minimise impact on the environment:
• The refrigerant gas must all be collected by specialist personnel with the necessary certification and delivered to the collection centres.
• The lubrication oil in the compressors and cooling circuit must be collected and delivered to the collection centres.
• The structure, the electrical and electronic equipment and the components must be sorted according to category and material and delivered to the
collection centres.
• If the water circuit contains mixtures with antifreeze, these must be collected and delivered to the collection centres.
In any case, comply with the national laws in force.
