know if i've even ever heard anybody say that you could do that before and maybe i was wrong in the way that i bled the nitrogen off the top but i operate off of dumb logic that's the way i you know i'm not the smartest cookie in the jar or any of that stuff okay but i just kind of think okay liquid refrigerant you know i know how to tell if there's non-condensables i know how to tell if you've got mixed refrigerants and it's very similar to the way that i checked if there was nitrogen in this refrigerant okay following pressure temperature relationships now i guess there's always a possibility there's still minute amounts of nitrogen in there it's always possible but i in my opinion i felt like i did everything that i could to try to get that rNUMBER_TOKEN and the nitrogen separated okay so i put the recovery tank in a bucket of water and i let it sit outdoor in the ambience over NUMBER_TOKEN degrees just sitting there right because i wanted even temperature all throughout that tank and then the logic was the saturation temperature better match what the outdoor air temperature or that the temperature of the water in the tank was okay and it didn't at first i wish i got footage of that because i only showed the before and then i showed the after i wish i would have shown you know the discrepancy it was a couple psi off and then i just vented vapor off the top of the cylinder right and it wasn't really vapor i just vented out of the vapor port and i vented the nitrogen out of the top of the cylinder until the saturation temperature and then i let it sit for another hour while i was doing other things and then verified that it was correct and it stayed equal the water temperature and the saturation temperature so i'm curious on your guys's thoughts on that too so leave me a comment down in the comments and let me know what you think do you think that was do you think i was incorrect for doing that because i mean it it seemed to work fine and everything was good you know um and then once i even you know you got to be careful too on those carrier units your placement when you're working on package units it's convenient to put the probes in the side of the unit but it's not always the most accurate place so you guys saw that i was having weird temperature issues and airflow issues and then once i moved that return air probe from the side of the unit actually into the return air stream down by the filters it kind of solved my problem so um this was an interesting one i run into these weird strange problems on a regular basis it's kind of fun you know these are the ones that i really enjoy these challenges and these i do find it odd that the customer chose to repair this unit i know i'm going to get a bunch of people commenting but guys i go to my customer and i say do you want to try using alternative refrigerants and they say no because i tell them look there could be good things you can save money but it can also go bad too i told the customer in this situation i said the cost comparison on a unit like this is going to be well over a thousand dollar difference if i was to use an alternative refrigerant
