The Yellow Jacket vacuum meter is better than a bourdon tube so don't panic. ALL ITEMS IN HOOK UP ARE AVAILABLE AS REPLACEMENTS. The Yellow Jacket vacuum meter is better than a bourdon tube so don't panic. Another annoying part about the 14777 is that it likes to turn off automatically every 5-10 minutes or so, which is really ridiculous IMO, given the usage for which it was supposedly designed.
You are adding moisture to the system. If you have vacced down to below 2000 microns, all the residual refrigerant in the oil would have boiled off, so any rise on your vacuum rise test indicates moisture in the system....... Heres what I do.
Digital gauges are the way to go. Social to popular belief. Testo Smart Probes App The Testo 552 uses Bluetooth to link to your smart phone or device utilizing the free Testo SMART Probes App, which is a powerful and easy-to-use tool. How much did the Vac-U-Ator and the fluid cost. PS: On sincere oil systems. The innovative testo 552 utilizes a sensor that, unlike the competition, requires no cleaning and is not affected by contamination. Warning: The topics covered on this site include activities in which there micron gauge hook up the potential for serious injury or death. I did it to my 14777 anyway and met my vac pump pull down to about 20 microns. Comes with a maintenance-free absolute pressure sensor making it ideal for evacuating refrigerant systems or heat pumps. I hook up the core remover and pull the core on the low side, then I take the actual core remover off the difference and hook a 5' low perm hose and the micron guage off the back port. If you suspect moisture is in the compressor. I will run the pump 10 min.
Micron Gauge - Not sure if it could've done lower, but I really didn't care as long as it pulled down below about 400, since I don't plan on going lower than that in any of my vehicles.. THE DV-29 ALSO ELIMINATES OTHER PROBLEMS WHEN ATTACHING THE VACUUM GAUGE ONTO THE SYSTEM.

Always use proper safety precaution and reference reliable outside sources before attempting any construction or remodeling task! How many guys use them? I'm a believer in them, allot of guys around here just use their gauges and let the vac pump run fo a hour or so and call it good, and get away with it. How they know the system is evaced. I don't know, have seen it take an hour to 3 hours to get down to 400 microns. We all use them, not to use one is just guessing. I also use a micron gauge, don't like guessing. To speed up the vacuum oil must be changed after every use of the pump and use nitrogen before you start. It absorbs soem of the moisture in the system. I will run the pump 10 min. Replaced TXV on Water Furnace today vacuum took an hr and had 385 micron using this system. Micron tells the story. I keep one of those nilla folder type paper tags with the wire on it attached to my vac pump and log the date when I change the oil. Digital gauges are the way to go... Would be cool if they had a speedy bar graph like my Fluke 87 in addition to digits so you get a visual sweep if something unexpected happens. R410A, doesn't care if moisture is in the system or not. POE likes to absorb it. And then react with the winding. If you ever add POE to a system. You are adding moisture to the system. You can't vacuum moisture out of POE. So anytime you open an existing system to replace a part between the service valve and the compressor. And you won't be able to vacuum it out. This is why you are suppose to change the LL filter drier when ever you open a system. So the LLFD can remove any moisture left in the system. PS: On mineral oil systems. Moisture that is under the oil, won't be removed by a vacuum either. This is one of the reasons a triple evac is recommended. It stirs up the oil and moisture in the system, and helps bring the moisture up from the oil. If you suspect moisture is in the compressor. Then use a heat gun on it while vacuuming the system. Contrary to popular belief. POE has been around and used long before R410A came out. I know that you can't pull any moisture out of POE oil Um, yes you can. I really cant see the wide spread use of POE oils in modern refrigeration if it hold moisture. The fact is, you can't tell if you have removed the moisture from the system if yo have not used a vacuum gauge. Just out of interest, how many of you perform a vacuum rise test at the end of your vac to check for moisture? If you have done a strength and tightness test you know there is no leak, so the vac should not rise. If you have vacced down to below 2000 microns, all the residual refrigerant in the oil would have boiled off, so any rise on your vacuum rise test indicates moisture in the system....... YOU SHOULD ALWAYS USE A VACUUM GAUGE! You can triple evac all month long. And you won't pull the moisture out of POE oil. You need filter driers to remove moisture from POE oil. POE has been used in refrigeration since the early 90's. Yes, some oil escapes the compressor during normal operation, but not enough to carry all of the moisture with it.... Vac Vac Vac By your argument, if you suspect moisture in the oil then you should replace it. As POE is extremely hygroscopic, the new oil charge WILL absorb more moisture from the atmosphere when you charge it. You can never eliminate exposure to the atmosphere, just minimise it All the oil circulates through the system. Most of the oil is in the sump at any one given time. But it all circulates through the system. Then R410A could use mineral oil. The reason it can't use mineral oil. Is that it doesn't mix well with it. And won't be able to return the oil to the compressor. If all the oil didn't circulate through the system. Then acid clean up by filters would be impossible. Since the filters require all the oil to pass through them to move the acid. Even if only the same 10 ozs of oil ever moved through the system. The oil that went through the filter drier would give up its moisture to the filter drier. Be returned to the compressor where it would absorb more moisture from the oil in the sump. Pass through the filter drier again. And give ups its moisture again. And repeat that process until the moisture was at a level lower then what it is, just from opening the oil container. Now if you don't believe that. Explain how an acid removal filter removes acid from the system. Sporlan, and Parker Sporlan now onwed by parker have tech sheets on how oil circulates through the system. On how and why acid filters, and filter driers work.
