About the EPA Type 1 Certification Exam
Why is the Type 1 EPA exam important?
Another challenge you’ll face when studying for your EPA Type 1 is that there is virtually training for the exam, it is all self study, which can be very boring. This is 100% book exam with no field test, you all the studying you’ll have to do will be a book setting. The EPA does not provide training either. There is no limit on the amount of re-tests you can do for the EPA refrigerant certification but the exams can get pricey because you’ll have to pay the cost to re-take the exam again.
Some important highlights from the EPA Certification Type 1 Exam
Recovery equipment fittings must be equipped with low-loss fittings which can be manually or automatically closed when disconnecting hoses in order to prevent refrigerant loss. All appliances must have a service aperture valve for recovering and charging refrigerants. Self-contained (active) recovery equipment uses its own power to recover the refrigerant from systems and is capable of reaching the required recovery rates with or without the compressor operating. A system-dependent (passive) recovery process captures refrigerant into a non-pressurized container. The system-dependent equipment uses the system’s compressor, an external heat source, or a vacuum pump to recover the refrigerant. A vacuum pump can only be used as a recovery device in combination with a non-pressurized container and cannot be used with self-contained recovery equipment (pressurized container). Small appliances used in campers or other recreational vehicles may use refrigerants not covered in Section 608, such as ammonia, hydrogen or water and therefore, should not be recovered using current EPA-approved recovery devices. Similarly, systems built before 1950 may have methyl formate, methyl chloride, or sulfur dioxide as refrigerants and require special recovery equipment.
