Due to the unusually high pressures and hazardous gasses used in refrigeration
and air conditioning, only TRAINED refrigeration and air conditioning
technicians should use this equipment. Proper procedures must be used.
Section 608 of the Federal Clean Air Act requires that all persons who
maintain, service, repair, or dispose of appliances must be certified since
