My favorite ones to make fun of with the guys who review tools and products. But they’ve never use a recovery machine in their life probably did not even know when existed prior to some tool company from China. Sending them one to ask them to do a review on it and would provide them with an Amazon link, so they can make their little percentage profit, off selling a air conditioning tool.
Great job with the video. ALTHOUGH, you are using the WRONG NYLOG (RED) and you should be using BLUE NYLOG! RED NYLOG is for "mineral oil" based systems. From the manufacture and actual inventor himself, John Pastorello (snip) : "Nylog Blue with any refrigerant or system oil. We make two versions of Nylog, one with Mineral oil, (the Red) and the other with POE, (the Blue). Nylog Blue can be used universally. The only reason we still offer and produce the Nylog Red is because too many technicians have never educated themselves that oils can be mixed. Just remember that you can use POE with any refrigerant/oil, but you cannot use 100% Mineral or AB to run an HFC system. About 90% POE is needed in an HFC system to carry residual MO or AB. Hope this helps... Thanks, John Pastorello, Refrigeration Technologies"
@@garybuffington6021 yes I know. It all they had . Our hvac parts house was out for week at the time I made this video. I now order it six packs at a time so I don’t run out.
@@coldfinger459sub0 At least you are ahead of the curve! I have not personally met or known any other Automotive Technicians to use Nylog as side from seeing it being used on RU-vid. . Clearly they do not know what they are missing out on. I just used some Blue Nylog on a neighbor's Jeep Wrangler 2 days ago. I was watching your Fieldpiece Equipment videos and thinking about buying some more portible equipment. My older dual (R12/R134a) Robinair RRR machine seems to have issues after not being used for like 3 years at home. Laughed it the old Robinair then went to pull out my spare "brand new" unused RTI Acrtic Air Pro RHS980 from being stored in my enclosed trailer. The dang RTI RRR Machine won't fill it's internal tank. Talk about bad luck! That is what i get for thinking ahead and planning for Robinair replacement. Keep the videos coming brother! Master Automotive Technician here and Former FL LEO too.
@@garybuffington6021 before NYLOG My father was using Vaseline because Vaseline is made out of mineral oil and back in the 1950s and 1960s 12 refrigerant and 22 refrigerant both used mineral oil as a refrigerant oil . Also used silicone grease a.k.a. spark plug boost, grease or dielectric grease . These are all things Automotive used since the 50s . Or at least the ones with an education.. They also used micron gauges back in the 50s. I was raised to learn to use an analog mic when I started in the 70s.
@@pipperoniexpress no cam sand. That takes time to set up. I have too much work to be playing with setting up cameras or lights or sound or editing. None of that that happens in my videos. Only people who don’t have work And spend all their time making nice videos
Thank you for taking the time to make this video, Tom. I'm wondering if one has to buy a different set of manifold, hoses and recovery pump for r1234yf systems.
You should that is best practice. Especially if more than one person is going to use the equipment and nobody remembers what kind of refrigerant or oil were last used or make it to practice to Flushing, clean out the system of the unit or hoses engages.. I have several sets of gauges but when I use my one set that I use for different refrigerant with different oils . I have a pressurized cylinder that’s 99% alcohol. I just hook up my yellow hose press the valve in at high pressure. It blows through the alcohol through the hoses and gauges play need it out. Then I hook it up to the nitrogen and blow through 600 psi of dry nitrogen. Hook it up to the vacuum pump. It takes it down to flow 100 µm and I’m ready for the different refrigerant or different oil.. On the recovery machine, I blow through it with dry nitrogen, and then pull the vacuum on the recovery machine to prepare it for use with a different gas . I do have three recovery machines but when I do have to switch one to a different gas, that’s the procedure I go through..
@@saturno4236 that goes in a separate recovery container just for contaminated refrigerant. Then you go down to your local commercial refrigeration supply house for the refrigerant recycling system and exchange your tank. You give them the old tank filled with refrigerant In exchange for another refrigerant recycling tank. Just like when you go down to the auto parts store, recycles engine oil or your coolant where you drop off your recycling ♻️ program.
Never go by the colors that are on the recovery tanks. One tank manufacturer may have the blue valve as the liquid and then another tank manufacturer will have the red so read the label or the imprint on the valve do not judged by the color. Usually to protect your machine from debris you would put a filter dryer on your yellow refrigerant hose leading to your recovery machine. It’s only purpose is to block small metal particles or any other debris from getting into your recovery machine and damaging the pistons and cylinders. I take the chance I know I’m recovering from a clean working system and I’m only recovering from the vapor side so I’m not pulling out liquid refrigerant or oil or any debris just a vapor gas into my recovery machine.
