1. Which of the following is considered a small appliance under EPA
Section 608?
A) A central air conditioning system with 20 pounds of refrigerant
B) A refrigeration system containing 5 pounds of refrigerant or
less
C) An industrial chiller with 50 pounds of refrigerant
D) A commercial rooftop unit with 25 pounds of refrigerant
B) A refrigeration system containing 5 pounds of refrigerant or less
Rationale: EPA defines small appliances as self-contained refrigeration
or air-conditioning units containing 5 pounds or less of refrigerant.
2. What is the maximum amount of refrigerant you can recover from
a small appliance using a non-ozone-depleting substitute if the
compressor is operational?
A) 90%
B) 80%
C) 95%
D) 100%
,A) 90%
Rationale: For Type I appliances, the EPA mandates recovery of at
least 90% of the refrigerant when using a functioning compressor.
3. Which of the following tools is required for Type I certification
recovery?
A) Electronic leak detector
B) Manifold gauge set and recovery cylinder
C) Vacuum pump
D) Nitrogen regulator
B) Manifold gauge set and recovery cylinder
Rationale: A manifold gauge set and a recovery cylinder are essential
for proper refrigerant recovery in small appliances.
4. What is the purpose of a recovery cylinder?
A) To store refrigerant during charging
B) To permanently contain recovered refrigerant
C) To test refrigerant pressure
D) To measure refrigerant temperature
B) To permanently contain recovered refrigerant
Rationale: Recovery cylinders are designed to safely store recovered
refrigerant before recycling or reclamation.
5. When recovering refrigerant from a small appliance with a non-
operating compressor, what is the minimum required recovery
efficiency?
A) 80%
B) 90%
C) 95%
D) 100%
,C) 95%
Rationale: EPA regulations require a minimum of 95% recovery when
the compressor is not operational.
6. Which refrigerant type is commonly found in older small
appliances?
A) R-134a
B) R-22
C) R-410A
D) R-32
B) R-22
Rationale: R-22 was widely used in older small appliances before
being phased out under the Montreal Protocol.
7. How often must recovery equipment be leak-checked according
to EPA regulations?
A) Before every recovery
B) Every 6 months
C) Only when the unit is serviced
D) Annually
A) Before every recovery
Rationale: The EPA requires that recovery equipment be checked for
leaks before each use to prevent refrigerant release.
8. What type of certification is required to service small appliances
containing refrigerant?
A) Type II
B) Type III
C) Type I
D) Universal
, C) Type I
Rationale: Type I certification covers the handling of small appliances
with 5 pounds or less of refrigerant.
9. Which of the following is an acceptable method to identify a
refrigerant?
A) Smelling the refrigerant
B) Using a color chart on the cylinder
C) Using a refrigerant identifier or cylinder label
D) Estimating based on appliance age
C) Using a refrigerant identifier or cylinder label
Rationale: Proper refrigerant identification requires a reliable method
such as a refrigerant identifier or verified cylinder label.
10. What is the first step before servicing a small appliance?
A) Charge with refrigerant
B) Recover any remaining refrigerant
C) Replace the compressor
D) Vacuum the system
B) Recover any remaining refrigerant
Rationale: EPA mandates recovering refrigerant from the appliance
before performing any service to avoid emissions.
11. Which of the following is NOT a requirement for recovery
cylinders?
A) Marked with refrigerant type
B) Hydrostatic test certification
C) Equipped with a pressure relief device
D) Used as a permanent storage container in the appliance
