Vann! He instructed a camt class that I attended. Smart fella
Great job 👍, proper information is always essential and a important part of helping you be the best and safest technician you can. knowledge is a key part of your job as well as taking care of your equipment. Thank you for time and sharing your education with us.😀
Please make a video showing these Tech's how to put that refrigerant back into the system using that reclaimer bottle
Did you pull the schrader valves? Also when you weighed the recovery tank you had no hose attached when you looked at the weight saying you had recovered you did have a hose attached. There is weight to the hose so how do you allow for that? I would have thought you would remove and purge but that means a lot of purging if you are just pulling the charge to get a weight and returning it to the compressor right after getting that weight and figuring what you have to add or subtract?
Thanks for the very informative video, I am studying AC recovery for automotive purposes and videos like this are very helpful. One question, when recovering into a new cylinder (purged and vacuumed down) can you put all the refrigerant back into the system or since it was recovered into a vacuum you can only get a percentage of it? For example I recover 3 lbs into a cylinder which was at 29.9 inHg I am assuming I cannot get that 3 lbs back into the system? Is there a percentage I can get back out of the cylinder? Thanks!
Not much of a purge. When I put an electronic leak tester on the fitting it took MUCH more of a purge to get to the beginning of some refrigerant flow. Also, what about purging the black recovery hose? Lots of air in there! Could have also done a better job of demonstrating weight compared to tare to ensure no refrigerant was in the recovery tank. As others commented, should ideally pull the Schrader valves too.
good stuff
Did you use the liquid line at all ? Did you use the high and low side together to get the refrigerant out ?
Can the recovery machine take in liquid refrigerant and pump liquid into the tank?
Or can it take in only gaseous refrigerant? Can it output either liquid or gas ?
Why does the tank have a red valve and blue valve? What if the tank has only a single valve, can you still use it for recovery?
