EPA Core 3

Which process is defined as removing refrigerant (in any condition) and storing it in an external container to be put back in the same system?

• Reclaim

• Recover

• Recycle

Which process is defined as cleaning the refrigerant by oil separation and passing it through one or more filter-driers?

• Reclaim

• Recycle

• Recover

Which recovery device uses an active recovery unit to draw refrigerant from the appliance?

• Self contained

• System dependent

Which process involves chemical analysis to determine if the refrigerant is back to new product specifications?

• Reclaim

• Recover

• Recycle

Can all recovered refrigerants be mixed into the same container?

• No

• Yes

Recovery efficiency will be dependent on which of the following?

• Ambient temperature

• All of these

• Amount of moisture

• Size of the appliance

What will using long hoses during the recovery process result in?

• Increased pressure drop, increased recovery time, and increased emissions

• Increased pressure drop, decreased recovery time

• Decrease pressure drop, decreased recovery time

Recovered refrigerant that is contaminated must be recovered into:

• A tank with other types of refrigerant in it

• The same tank as the refrigerant that isn't contaminated

• A separate tank

What is the purpose of evacuation and dehydration?

• To remove non condensibles(air) and water vapor

• To improve the vacuum pump

• To cause hydrofluoric acids to form

• To add water and water vapor to the system

The final system vacuum measurement should be done with:

• The vacuum pump turned on

• The vacuum pump turned off

• A multimeter
