Nice video, but for the cost I can get the VP85. As a matter of fact I just did last month. It’s a nice little pump, but I like being able to walk away during a vac to grab lunch or whatever and let the vac continue without watching a battery. Love my new trublue three hose set as well.
The Fieldpiece VP85 is still one of my favorite pumps. I really like the manifold and the quick oil change. Three reasons for the video, one to show that pump size is secondary to hoses and that 2 CFM is very viable, and that a battery pump can easily get the job done. For a new startup, I would grab a battery pump any day of the week. If I was doing service work on anything under 5 tons there is no reason that I would not use. it.
Good video ! But, systems have a compressor , condenser coil with residual refrigerant in the oil that has to be boiled out & a New drier after a repair. Add a 5 ton condensing unit to your set up there , a drier , & u have a better real world test. This is a Good test for New installs though. Cool Bench set up ! any eta on Getting R-417C ( Hot shot 2 ) added to measure quick ? Good vids !
The refrigerants are added all ready for the new release. That was very much a real-world test for a new installation. As far as a larger system, or a really wet one I might still use a corded pump simply because of the larger oil capacity and a gas ballast. There is no reason though that if the system was not wet that it could not be used for service. I would simply pull to 500 instead of 100-250. There is no reason not to have two pumps. I have a corded drill and a cordless for the same reasons.
Yeah... on some of the old junk refrigeration equiptment I work on, it seems like it takes forever to get them good and dry. Couldn’t rely on a cordless pump for that. New installs or reach ins and stuff. Hell yeah. Sounds like a good option. Don’t hardly have the space for anymore tools though
@mQ - Yea, it definately could be convenient as a second pump. its a nice thing not having to run a cord across the floor. ( Trip & fall restaurant accident would not be good in california ) Also Thank you for adding The R-417C ( Hot shot 2 ) to MQ.
Really appreciate this video and it tells much. Quick thought and question... Being that we shouldn't put refrigerant through the hoses, it makes sense that you would have to have a lot of refrigerant under pressure to make it bad for the hoses. Of course, we all know that contaminants in the system and residual refrigerant can go through the hoses correct when being pulled out by vacuum? Does that hurt anything with the hoses? I think I've actually seen you clean them out with alcohol? When necessary
Triple evacuations are More for systems that Have sucked water into them , Burnouts , and systems that Have Had Line sets With Flush ran through them , Triple evacuations really excel when a system has been wet inside because the Nitrogen is dry & collects moisture when it enters the system , soaks up moisture when it is in the system , and then takes the moisture out with it as it leaves the system. Speeding up Evacuation time is its real purpose on Wet systems. Thats where it really excells.
No oil in a new system greatly reduces evacuation time. With volatiles trapped in system distributed oil, can take much longer. Additional nitrogen flushes help sweep volatiles out quicker which doesn't help much when there is no oil yet distributed in a new system.
Jim, do you have any plans on enabling MQ app to have live readings with the testo 350 manifold, I think it would be pretty sweet pairing the 350 with field piece temp probs.
This setup would be great when you have areas with little or no outlets. This setup would work great to what I did on a 2nd floor unit with about the same amount of line set. How would you compare the 2 CFM pump evacuation time or effectiveness to the Appion rated hoses compared to the TruBlu hoses in the video?
Great video Jim. That pump and hose setup would be awesome to have on new system installs. Going to pass this on to my boss
My pump arrives Wednesday .
Thank you Very Much Jim for your video TruBlu hoses are the best.
Now THAT is how to show them where they can't comment about realism. Great video.
Anti DIY HVAC u got that right Ted
Thanks

Great job. Would you please can you show vacuum with appion 1/2 hose. Thank again
Hey jim great video. Question with this new set of vacuum hoses and accessories do you still practice triple evacuation. Or is it still necessary.
Triple evacuation is really not needed when you can achieve vacuums this deep.
Triple evacuations are More for systems that Have sucked water into them , Burnouts , and systems that Have Had Line sets With Flush ran through them , Triple evacuations really excel when a system has been wet inside because the Nitrogen is dry & collects moisture when it enters the system , soaks up moisture when it is in the system , and then takes the moisture out with it as it leaves the system. Speeding up Evacuation time is its real purpose on Wet systems. Thats where it really excells.
No oil in a new system greatly reduces evacuation time. With volatiles trapped in system distributed oil, can take much longer. Additional nitrogen flushes help sweep volatiles out quicker which doesn't help much when there is no oil yet distributed in a new system.
Goodman changed up the circuitry on that coil I see to make the apex more active
Bulloney !!
That Ted stalks you Joe on the dark web. Haha
