The state of a refrigerant leaving a refrigeration system's liquid receiver is:
a.) Low-Pressure Liquid
b.) Low-Pressure Gas
c.) High-Pressure Liquid
d.) High-Pressure Gas - correct answer ✔✔c.) High-Pressure Liquid
The refrigerant's pressure is constant leaving the refrigerant below the interface subcooled.
When the annualized leak rate reaches _____ or more, leaks in industrial process and
refrigeration units must be repaired with a 50-pound charge or larger.
a.) 40%
b.) 30%
c.) 10%
d.) 20% - correct answer ✔✔b.) 30%
EPA regulations require that all commercial and industrial process refrigeration containing more
than 50 lbs. of refrigerant must be repaired when the annual leak rate exceeds 30%. (Page19

pull?
, a.) 500000 Microns
b.) 50000 Microns
c.) 500 Microns
d.) 5000 Microns - correct answer ✔✔c.) 500 Microns
A finishing vacuum of 500 microns is acceptable for a new installation or a system being
serviced.
A high-pressure appliance with a capacity of less than 200 pounds. The level of an HCFC or HFC
refrigerant must be evacuated (recovered) to:
