QUESTION 1
What is the EPA definition of a Type II appliance?
A) Small appliances with 5 lbs or less of refrigerant
B) Low-pressure appliances like centrifugal chillers
C) High-pressure or very high-pressure appliances, except small
appliances and MVAC
D) Motor vehicle air conditioners
Answer: C
Explanation: Type II certification applies to technicians who maintain,
service, repair, or dispose of medium, high, and very high-pressure
appliances. This explicitly excludes small appliances and motor vehicle
air conditioning systems (MVAC). Low-pressure appliances like
centrifugal chillers fall under Type III certification.

QUESTION 2
Which refrigerant is classified as high-pressure under EPA 608 Type II?
A) R-11
B) R-123
C) R-410A
D) R-113
Answer: C
Explanation: R-410A is a high-pressure refrigerant commonly used in
modern residential and commercial air conditioning systems. R-11, R-
123, and R-113 are low-pressure refrigerants typically found in
centrifugal chillers and fall under Type III certification.
QUESTION 3
When recovering refrigerant from a high-pressure system with a non-
operational compressor, technicians must use:
A) System-dependent recovery equipment
B) Self-contained recovery equipment
C) Either type
D) Recovery is not required
,3|Page
Answer: B
Explanation: Self-contained recovery equipment is required when
recovering refrigerant from a system with a non-operational or leaking
compressor. System-dependent recovery equipment relies on the
system's own compressor to function, which is not available in this
scenario.
QUESTION 4
What is the maximum allowable leak rate for a commercial
refrigeration system containing R-22 before mandatory repair is
required?
A) 10% per year
B) 15% per year
C) 35% per year
D) No threshold exists
Answer: B
Explanation: For commercial refrigeration appliances, the leak repair
threshold is 15% per year. This applies to systems containing 50 lbs or
more of refrigerant. Different thresholds apply to other categories: 10%
for comfort cooling and 35% for industrial process refrigeration.
QUESTION 5
, 4|Page
Recovery cylinders for high-pressure refrigerants must be colored:
A) Yellow with gray collar
B) Gray with yellow collar
C) Green
D) Blue
Answer: B
Explanation: The EPA requires specific color coding for refrigerant
recovery cylinders. High-pressure refrigerant cylinders are gray with a
yellow collar or top. This standardization helps prevent cross-
contamination and ensures proper refrigerant identification.
QUESTION 6
What is the required leak rate trigger for repairing Comfort Cooling
appliances containing 50 lbs or more of refrigerant?
A) 5% per year
B) 10% per year
C) 20% per year
D) 30% per year
