Mixing different kinds of refrigerant can result in hazardous
toxic gases being released. Mixing with oils can lead to the
soil being contaminated in case of leaking refrigerant.
▪ Never allow refrigerant to escape into the atmosphere -
always extract and recycle with a suitable recycling
device.
▪ Always recycle refrigerant, thus keeping it separated
from oils and other additives.
▪ Only keep each type of refrigerant separate in suitable
pressure vessels.
▪ Dispose of refrigerants, oils and additives properly and
in accordance with the applicable national regulations of
