In this episode of the HVAC Know It All Podcast, host Gary McCreadie is joined by Eric Ruggles, Director of Engineering at Ritchie Engineering Co., Inc. (YELLOW JACKET), to discuss charging A3 flammable refrigerants with Yellowjacket's hydrocarbon charging kit. They cover assembling the charging setup, pre-filling hoses before weighing in a critical charge, and using a gas retention valve to reduce refrigerant loss during connections and disconnections. Ruggles brings Yellowjacket's equipment perspective to the practical handling of A3s and A2Ls. He explains why hose volume, non-sparking vacuum-pump components, recovery-machine safety, equipment labeling, and technician precautions matter when working with flammable refrigerants. Key Takeaways How to pre-fill a charging hose with refrigerant and re-zero the scale before charging a critically charged system. Why small-diameter hoses help reduce the amount of residual refrigerant left in a charging setup. How a Schrader core depression valve can connect to a system before opening the core and limit refrigerant loss during removal. Why technicians should take A3 safety precautions when a small refrigeration unit does not clearly identify its refrigerant. How brushless or sealed motors, non-sparking switches, and integrated cords reduce ignition risks in A2L-compatible vacuum pumps. Why recovery machines require proper equipment because they handle a continuous flow of flammable refrigerant and involve refrigerant connections. Noteworthy Quotes "You can screw this on without letting any gas out of the system or without impacting the system at all." – Eric Ruggles "Then you have a fully filled line set before you even charge the system at all, and that's what you're starting with." – Eric Ruggles "The motors have to be changed typically to brushless DC or completely sealed motors from an AC perspective." – Eric Ruggles "You can't have any sparking at the vacuum pump or recovery machine when we're in an environment that could have an A2L or an A3 flammable refrigerants." – Eric Ruggles "Recovery machines are more critical, making sure that you're using the proper equipment." – Eric Ruggles Episode Highlights:  [00:00] - Sponsor Ad: Factory Direct Filters      [00:43] - Introduction to Eric Ruggles & the Focus of the Episode   [02:15] - Eric begins demonstrating the A3 charging setup  [03:58] - Charging the System  [05:37] - Gas Retention Valve Purpose [06:37] - Non-A3 Charging Setup [09:33] - Why R290 Cylinders Are Small  [11:00] - A3 Refrigerant Safety  [13:04] - A2L Vacuum Pump Requirements  [16:18] - Identifying A3 Refrigerants [19:00] - Where To Reach Out to Eric   This Episode is Kindly Sponsored by: Cintas: https://www.cintas.com/hvacknowitall Cool Air Products: https://www.coolairproducts.net/ Factory Direct Filters: https://www.factorydirectfilters.com/ SupplyHouse: https://www.supplyhouse.com/tm Use promo code HKIA5 to get 5% off your first order at Supplyhouse!   Follow the Guest Eric Ruggles and His Company on: LinkedIn: https://www.linkedin.com/in/eric-ruggles-28a84424/ Company LinkedIn: https://www.linkedin.com/company/ritchie-engineering-co-yellow-jacket-/ Company Website: https://yellowjacket.com/   Follow the Host on: LinkedIn Profile: https://www.linkedin.com/in/gary-mccreadie-38217a77/ LinkedIn - HVAC Know It All: https://www.linkedin.com/company/hvac-know-it-all-inc Website: https://www.hvacknowitall.com Facebook: https://www.facebook.com/people/HVAC-Know-It-All-2/61569643061429/  Instagram: https://www.instagram.com/hvacknowitall1/    Follow the Podcast on: YouTube: https://www.youtube.com/@HVACKnowItAll Spotify: https://open.spotify.com/show/6LCBJGw0EHG03rdWHxUMce Apple Podcasts: https://podcasts.apple.com/us/podcast/hvac-know-it-all-podcast/id1359253455
