1. Recovery equipment used for the service or repair of small appliances must be certified by an EPA-
approved lab if the recovery equipment was made after:
- ✔️ November 15, 1993
2. Recovery devices made before 11-15-93 and used for recovering refrigerant from small appliances
must be capable of:
- ✔️ Recovering 80% of the refrigerant whether or not the compressor is operating or achieving a 4-
inch vacuum under conditions of ARI 740-1993.
3. EPA's definition of a small appliance includes:
- ✔️ A device manufactured, charged, and hermetically sealed in the factory with a charge of 5 lbs or
less.
4. Technicians with a Type 1 small appliance certification are certified to recover refrigerant during the
maintenance or repair of:
- ✔️ PTACs (Packaged Terminal Air Conditioners) with 5 lbs or less of refrigerant.
5. EPA requires that all small appliances be equipped with a service aperture or another device that is
used when adding or removing refrigerant from the appliance. For small appliances, this service port
typically:
- ✔️ Is a straight piece of tubing, called a process tube, that is entered using a piercing valve.
6. The EPA Section 608 certification must be renewed every:
- ✔️ Never.
7. It is an EPA regulation that any person who opens an appliance for maintenance, service, or repair
must have at least one self-contained recovery machine available at their place of business. The only
exception to this rule is for persons working on:
- ✔️ Small appliances.
, 8. The sale of CFC & HCFC refrigerants is:
- ✔️ Restricted to technicians who are EPA certified in refrigerant recovery.
9. Anyone who recovers refrigerant during maintenance, service, or repair of small appliances must be
certified as either a universal tech or a:
- ✔️ Type 1 tech.
10. When recovering refrigerant from a household refrigerator whose compressor does not run, it is
recommended that low and high side access valves be installed because:
- ✔️ It can help speed up recovery and required recovery efficiency.
11. If you install an access fitting into a sealed system:
- ✔️ The fitting should be leak tested before proceeding with recovery.
12. Before beginning a refrigerant recovery procedure, it is always necessary to:
- ✔️ Determine the type of refrigerant in the system.
13. When recovering refrigerant into a non-pressurized container from a refrigerator with an improper
compressor:
- ✔️ It is necessary to heat and strike the compressor with a rubber mallet.
14. When checking for the existence of non-condensable gases inside a recovery cylinder, why is it
proper procedure to allow the temperature of the cylinder to stabilize at room temperature before
taking a pressure reading?
- ✔️ Any comparisons to a pressure-temperature chart are only valid if both the pressure and
temperature of the refrigerant are stable.
15. A recovery cylinder that is 1/2 full of recovered R-410A at 90°F, in the absence of non-condensables,
will be pressurized to:
- ✔️ 300 psig.
