The refrigerant may not be discharged into the atmosphere, but must be returned to the manufac-

The ester oil in the compressor must also be disposed. As it contains dissolved refrigerant, it can
not be disposed like usual oils, but must be returned to the oil manufacturer.

If glycol or similar additives had been used, this liquid also has to be collected and disposed in
an appropriate manner and may under no circumstances be introduced in the local waste water
system.
