Information
Refrigerant R134a contributes to the greenhouse effect as soon as it is released into the Earth's atmosphere.
Refrigerant should not be released into the environment but is to be extracted from the refrigerant circuit using an extraction or service station. The extracted refrigerant is then prepared again on-site or returned to the manufacturer for environmentally-friendly disposal (varying or additional regulations may apply in certain countries).
