In this comprehensive video, learn how to safely use R290 refrigerant to repair a True Refrigeration cabinet. As one of the most well-know and widely-used commercial refrigeration brands out there, it’s important to understand the proper method for using R290.

Keep in mind that, before you begin the repair, there are some key safety procedures to perform:

  • Make sure that the True Refrigeration cabinet unit has a designated sticker that indicates it’s safe to use R290.
  • Don’t leave the system open for more than 15 minutes.
  • Always change the drier when the system is opened.
  • Use a micron gauge, combustible gas leak detector, a safety placard and a charging valve. Use the charging valve if you’re using a 1-lb cylinder R290 supply.
