EPA 608
This certification is required by law to handle refrigerants.
What is EPA 608 certification?
This is the most common method used to detect refrigerant leaks.
What is an electronic leak detector?
Type I certification covers appliances with this amount of refrigerant.
What is 5 pounds or less?
Type II applies to these types of systems.
What are high-pressure appliances?
Type III systems typically use this refrigerant.
What is R-11 or R-123?
This federal agency enforces refrigerant regulations.
What is the Environmental Protection Agency (EPA)?
Refrigerant oils absorb this from the air, which can damage systems.
What is moisture?
Examples of Type I appliances include refrigerators and this common household appliance.
What is a window air conditioner?
This refrigerant is commonly used in residential split A/C systems.
What is R-410A?
These systems operate under this type of pressure.
What is low pressure (often in a vacuum)?
This section of the Clean Air Act regulates refrigerants.
What is Section 608?
This must always be recovered before opening a system.
What is refrigerant?
This type of recovery equipment is typically used for small appliances.
What is a self-contained (active) recovery unit?
This component is often the most common leak point in high-pressure systems.
What are service valves or schrader valves?
This type of equipment is commonly classified as a Type III system.
What is a chiller?
This type of refrigerant has the highest ozone depletion potential.
What are CFCs?
This condition occurs when refrigerant is released into the atmosphere.
What is venting?
This method removes refrigerant using the system’s compressor.
What is system-dependent recovery?
This must be repaired when a system leaks above a certain rate.
What is a substantial leak?
This is added to raise system pressure before leak testing.
What is nitrogen?
This is the penalty (fine) for violating EPA refrigerant regulations (per day, per violation).
What is up to $37,500 (or current adjusted amount higher)?
This gas is often used to pressurize a system for leak testing (never oxygen).
What is nitrogen?
Before disposal, this must be removed from small appliances.
What is refrigerant (must be recovered)?
When recovering refrigerant, this condition must be avoided to protect the compressor.
What is overheating or running without refrigerant (low charge)?
Leaks in low-pressure systems often allow this to enter the system.
What is air and moisture?
