EPA Section 608 Study Guide Exam |Questions
with 100% Verified Answers
A "de minimus" release is: - ✔️✔️The quantity of refrigerant released in the course of making a
good-faith attempt to recapture and recycle or safely dispose of refrigerant.
A normal operational refrigerant release would be: - ✔️✔️Releases from purge cycle operation.
Releases of refrigerant that result from connecting or disconnecting gauge hoses: - ✔️✔️Are
permissable under the EPA regulations.
The four parts of the EPA Certification exam include: - ✔️✔️Core, Type I small appliances, Type II
high pressure and very high pressure appliances, and Type III low pressure appliances.
A product that is fully manufactured, charged, and hermetically sealed in a factory with 5 lb or
less of refrigerant is defined as: - ✔️✔️A small appliance.
It has been illegal to vent ozone depleting refrigerants from stationary equipment since: -
✔️✔️July 1, 1992.
Third party testing for recovery units has been required since: - ✔️✔️November 15, 1993.
Technicians have been required to pass and EPA certification exam to handle refrigerant since: -
✔️✔️November 14, 1994
It became illegal to vent replacement refrigerants in: - ✔️✔️November 15, 1995.
How is recovering in a receiver accomplished? - ✔️✔️The refrigerant is pumped into the receiver
with the king valve closed.
, Why is the push-pull method of recovery preferable for some systems with large quantities of
refrigerant? - ✔️✔️It is the quickest method.
A self contained recovery device: - ✔️✔️Does not rely on the system from which the refrigerant
is being recovered for its operation.
Why should some refrigerants NOT be recovered? - ✔️✔️Older machines may hold toxic
chemicals.
Why is it necessary to use special methods when recovering from Type III systems? - ✔️✔️Most
of these systems are very low pressure.
To prevent the system refrigerant from quickly dropping in temperature and pressure,
refrigerant recovery should: - ✔️✔️Begin with liquid.
Liquid refrigerant should always be recovered first from chillers: - ✔️✔️To keep from freezing the
water in the chiller tubes.
When connecting a recovery system for push-pull liquid recovery, the outlet of the recovery
unit is connected to: - ✔️✔️The discharge service valve on the system.
When connecting a recovery system for push pull liquid recovery, the inlet of the recovery unit
is connected to: - ✔️✔️The vapor valve on the refrigerant recovery cylinder.
To speed up refrigerant recovery: - ✔️✔️Use large-diameter, short length hoses.
The refrigerants that a particular recovery unit is designed for can be determined by: -
✔️✔️Looking for the AHRI/UL certification label.
