Special Note on Refrigeration
Emissions
World environmental scientists have
concluded that ozone in our upper
atmosphere is being reduced due to the
release of CFC fully halogenated
compounds.
Trane urges all HVAC service personnel
to make every effort to prevent any
refrigerant emissions while installing,
operating, or servicing equipment.
Always conserve refrigerants for
continued use.
