These flashcards cover key vocabulary and concepts related to the EPA Section 608 Preparatory Manual, focusing on refrigerant recovery, evacuation, and safety standards.

Recovery Unit

A water-cooled system that enables faster recovery of large quantities of refrigerant.

Refrigerant Evacuation

The process of removing refrigerant from a system to prevent freezing or other issues.

Recovery Compressor

A component of the recovery system that compresses the refrigerant during the recovery process.

Rupture Disc

A safety device that relieves pressure at a specified level, typically found in recovery vessels.

Vacuum Level

The pressure condition that should be attained in a system before charging.

Refrigerant Oil Heating

Heating refrigerant oil to 130°F to reduce refrigerant content before recovery.

Moisture Control

Using dry-nitrogen to prevent moisture from freezing during evacuation or dehydration.

Saturation Temperature

The temperature at which refrigerant changes state at a given pressure.

Charging Valve

The valve used to add refrigerant to a low-pressure appliance.

TLV-TWA
