BANK 400 QUESTIONS WITH DETAILED VERIFIED
ANSWERS / ALL EXAM QUESTIONS AND VERIFIED
ANSWERS |ALREADY GRADED A+|
Certification for Refrigerant Recovery - ANSWER-Anyone who
recovers refrigerant during the maintenance, service or repair of
small appliances must be certified as either a Universal
Technician or a Type I Technician.
EPA Refrigerant Capture Requirement - ANSWER-EPA
regulations require the capture of at least 80% of the refrigerant
from a small appliance with a non-operating compressor if the
technician is using either type of recovery unit.
Passive System-Dependent Recovery Method - ANSWER-When
using a passive system-dependent recovery method on an
appliance with an operating compressor, you should run the
(appliance's) compressor and recover the refrigerant from the
high side.

Passive System-Dependent Recovery Device - ANSWER-A
passive system-dependent recovery device for small appliances
captures refrigerant in a non-pressurized container.
Sale of CFC and HCFC Refrigerants - ANSWER-The sale of CFC
and HCFC refrigerants is restricted to technicians who are EPA
certified in refrigerant recovery.
EPA-Approved Recovery Devices - ANSWER-none of the above
refrigerants should be recovered with current EPA-approved
recovery devices.
Leak Repair Requirement for Small Appliances - ANSWER-it is
not mandatory to repair the leak but do so whenever.
