Guidelines

This checklist covers regulations issued by the U.S. Environmental Protection Agency under Subpart F, 40 CFR 82.150 to 82.166. A answer to a question indicates that this portion of the inspection complies with the EPA standard, an Occupational Safety and Health Administration (OSHA) standard, or with a nonregulatory recommendation. Definitions of terms in bold type are provided at the end of the checklist. This checklist does not cover motor vehicle air conditioners (MVACs). See the Service and Repair of Motor Vehicle Air Conditioners checklist. This checklist does not address regulations for approved equipment testing organizations, technician certification programs, persons who take the final step in the disposal process of small appliances or MVAC-like appliances, and reclaimer certification. appendixes A through D of the regulations 40 CFR 82.150 to 82.166 should also be consulted and include: Appendix A-Specifications for fluorocarbon refrigerants; Appendix B-Performance of refrigerant recovery, recycling, and/or reclaim equipment; Appendix C-Method for testing recovery devices for use with small appliances; and Appendix D-Standards for becoming a certifying program for technicians.

Definitions

Appliance: any device that contains and uses a class I or class II substance as a refrigerant and that is used for household or commercial purposes, including air conditioner, refrigerator, chiller, or freezer.

Class I refrigerants: include chlorofluorocarbons (CFCs), halons, carbon tetrachloride, and methyl chloroform.

Class II refrigerants: include hydrochlorofluorocarbons (HCFCs).

Equipment operations certification: a signed statement from a school that maintains, services, or repairs appliances except for MVACs and includes: (a) the name and address (including the county) of the purchaser of any EPA-approved equipment used to recover and recycle refrigerant; (b) the name and address of the establishment where the equipment will be located; (c) the manufacturer name and equipment model number, the date of manufacture, and the serial number of the equipment; (d) a statement that the equipment will be properly used in servicing appliances and that the information given is true and correct; (e) a signature of the owner of the equipment or other responsible officer. This equipment operations certification must be sent to CAA § 608 Enforcement Contact, EPA Region II, Jacob K. Javits Federal Building, 26 Federal Plaza, Room 5000, New York, NY 10278. [40 CFR 82.154(e) and 82.162]

High-pressure appliance: an appliance that uses a refrigerant with a boiling point between -50 and 10ºC at atmospheric pressure (29.9 inches of mercury). This definition includes appliances using refrigerants -12, -22, -114, -500, or -502.

Low-pressure appliance: an appliance that uses a refrigerant with a boiling point above 10ºC at atmospheric pressure (29.9 inches of mercury). This definition includes equipment using refrigerants -11, -113, and -123.

MVAC-like appliance: a motor-vehicle air-conditioner-like appliance. It includes mechanical vapor compression, open-drive compressor appliances used to cool the driver's or passenger's compartment of a non-road motor vehicle. This includes the air-conditioning equipment found on agricultural or construction vehicles. This definition does not cover appliance using HCFC-22 refrigerant.

Opening an appliance: any service, maintenance, or repair on an appliance that could be reasonably expected to release refrigerant from the appliance to the atmosphere unless the refrigerant was previously recovered from the appliance.

Small appliance: any of the following products that are fully manufactured, charged, and hermetically sealed in a factory with 5 pounds or less of refrigerant: refrigerators and freezers designed for home use, room air conditioners (including window air conditioners and packaged terminal air conditioners), packaged terminal heat pumps, dehumidifiers, under-the-counter ice makers, vending machines, and drinking water coolers.
