Notes on handling refrigerant
R134a
Type 903.662
The refrigerant R134a is colorless and odorless.
At normal temperatures it is neither toxic nor
flammable, and will not explode in the air, no
matter what its concentration.
The R134a refrigerant may only be used in air
conditioning systems for which R134a has been
specifically approved.
The refrigerant R134a must not be mixed with
other refrigerants (e.g. R12).
The refrigerant R134a does not contain any
chlorofluorocarbons (CFC). In contrast to other
refrigerants (e.g. R12) it is not hazardous to the
environment at normal temperatures. The
refrigerant R134a does not damage the earth's
ozone layer.
Despite these benefits, the use of suitable
equipment to discharge and process used gas and
to recharge systems with new refrigerant R134a is
absolutely mandatory; this equipment must include
integral disposal and reprocessing capabilities.
