EPA TYPE 1 EXAM QUESTIONS WITH
REVIEWED CORRECT DETAILED
ANSWERS
When installing any type of access fitting onto a sealed system
a. The system must be pressurized with dry nitrogen before Leak testing can be
attempted
b. The fitting need not be leak tested until the total repair is completed
c. is not necessary to leak test and access fitting
d. The fitting should be leak tested before proceeding with recovery - Answer-d. The
fitting should be leak tested before proceeding with recovery
When R-410A is recovered from an appliance, it;
a. should be recovered into a recovery vessel that is clearly marked to ensure that
mixing of refrigerants does not occur
b. need not be recovered since R-410A is not one of the refrigerants covered by the
Clean Air Act
c. can be mixed with R-123a but not with R-22 during the process p
d. can be mixed with either R-32 or R-125a during the recovery process, since R-410A
is a mixture of those two refrigerants - Answer-a. should be recovered into a recovery
vessel that is clearly marked to ensure that mixing of refrigerants does not occur

b. when using passive recovery devices on small appliances with non-operating
compressors
c. when using system dependent active recovery devices
d. when using self-contained recovery devices - Answer-b. when using passive recovery
devices on small appliances with non-operating compressors

a. a domestic refrigerator
b. a single compressor, large commercial walk-in freezer
c. a reciprocating liquid chiller
