World environmental scientists have
concluded, based on the best currently
available evidence, that ozone in our
upper atmosphere is being reduced
due to release of CFC fully halogenated
compounds.
Prior to installation, operation, service
or maintenance on this equipment,
refer to “Refrigerant Emission Control”
in the Periodic Maintenance Section.
