Q1. Which of the following appliances is categorized under EPA Type
II certification?
A) Small appliances containing 5 pounds or less of refrigerant
B) Very high-pressure appliances using R-744
C) High-pressure or medium-pressure appliances containing more than 5
pounds of refrigerant
D) Low-pressure appliances using R-123
Answer: C) High-pressure or medium-pressure appliances
containing more than 5 pounds of refrigerant
Explanation: Type II certification covers technicians who maintain,
,service, repair, or dispose of high-pressure and medium-pressure
appliances containing more than 5 pounds of refrigerant. Small
appliances are Type I, and low-pressure appliances are Type III.
Q2. What is the primary purpose of recovering refrigerant from a
Type II system before opening it for service?
A) To test the acidity of the lubricant
B) To prevent venting of ozone-depleting substances and greenhouse
gases into the atmosphere
C) To allow the compressor oil to cool down
D) To clear non-condensables from the system lines
Answer: B) To prevent venting of ozone-depleting substances and
greenhouse gases into the atmosphere
Explanation: The EPA strictly prohibits the intentional venting of
ozone-depleting substances (like CFCs and HCFCs) and substitute
refrigerants (like HFCs and HFOs) under Section 608 Clean Air Act
regulations to limit environmental damage.
Q3. For a medium-pressure appliance containing less than 200
pounds of R-22, what is the required evacuation level using
recovery equipment manufactured after November 15, 1993?
A) 0 psig
B) 4 inches of Hg vacuum
C) 10 inches of Hg vacuum
D) 15 inches of Hg vacuum
Answer: C) 10 inches of Hg vacuum
,Explanation: According to EPA regulations, technicians must evacuate
a medium-pressure appliance (or isolated part of one) containing
less than 200 pounds of refrigerant to 10 inches of mercury (Hg)
vacuum before opening the system.
Q4. What evacuation level must be reached for a medium-pressure
appliance containing 200 pounds or more of refrigerant using post-
1993 recovery equipment?
A) 10 inches of Hg vacuum
B) 15 inches of Hg vacuum
C) 20 inches of Hg vacuum
D) 25 inches of Hg vacuum
Answer: B) 15 inches of Hg vacuum
Explanation: For medium-pressure systems holding 200 pounds or
more of refrigerant, the EPA mandates a deeper vacuum of 15
inches of Hg because of the higher volume of potential atmospheric
release.
Q5. If a high-pressure appliance contains less than 200 pounds of
refrigerant, what is the required recovery vacuum level using
modern equipment?
A) 0 inches of Hg vacuum
B) 10 inches of Hg vacuum
C) 15 inches of Hg vacuum
D) 20 inches of Hg vacuum
, Answer: B) 10 inches of Hg vacuum
Explanation: High-pressure appliances (such as those using R-22 or
R-410A) containing less than 200 pounds of refrigerant require a
vacuum level of 10 inches of Hg during the recovery process.
Q6. For a high-pressure appliance containing 200 pounds or more of
refrigerant, what level of vacuum must recovery equipment be
capable of achieving?
A) 10 inches of Hg vacuum
B) 15 inches of Hg vacuum
C) 20 inches of Hg vacuum
D) 25 inches of Hg vacuum
Answer: B) 15 inches of Hg vacuum
Explanation: High-pressure appliances with a total charge of 200
pounds or more require an evacuation level of 15 inches of Hg
vacuum to ensure maximum refrigerant vapor extraction before
opening the system to the atmosphere.
Q7. When using recovery equipment manufactured before November
15, 1993, what is the required level of evacuation for a medium-
pressure appliance containing less than 200 pounds of refrigerant?
A) 0 psig
B) 4 inches of Hg vacuum
C) 10 inches of Hg vacuum
D) 15 inches of Hg vacuum
