Wow, I didn't realize you could pressurize it back into the condenser. I figured you had to suck it out, re-vaccuum the entire system and fill it back in. This is great info! Thank you!
Same here!
Thank you so very much for this. I did indeed recover a few split AC's alternative way, but this is much more elegant and reliable method.
I have to move one this year, I will do this, thanks for posting!
I am so impressed with the Pioneer system. Thank you for this video.
Thanks for the feedback!
This worked like a champ. I had a new install with a defective indoor unit that I needed to replace. I recovered the refrigerant using this process, replaced the indoor unit and went through the install again. Works perfect now!
What type of gauge did you use to make it was all recovered? Did you purge it before use
@@zanehenley3394 Just a regular set of vacuum gauges. Once I had replaced the indoor unit, I did a normal install startup on the system, including vacuuming the lineset to 200 microns. I've used the unit all winter as my primary source of heat in my bonus bedroom.
When you hooked up the gauge to monitor the unit when u wer backing up the refrigerant did you purge the line going to the gauge to get the air out? I just did mine an I forgot to purge it so not sure what’s gonna happen it prob got a little air in it
@@zanehenley3394 There is no need to purge the line. You are monitoring the pressure going back into the pump. Your gauge set isn't actively involved in the process.
@@dougphelps6917You always need to vacuum the system, anytime it is open.
Moisture in the air combines with refrigerant to make acids, vacuum lowers the boiling point of water and the moisture is vacuumed out.
Wow someone was telling me I needed to buy a recovery machine. Thanks for doing this now I can transfer my unit to my other truck instead of having to buy another one
I was just reading about this in the service manual. The manual shows using a standard two-gauge manifold, hooking the hose to the low side gauge. You just have to make sure both valves on the manifold are closed, and there will be no leaking anywhere. You're just reading the pressure level from the service port, as you would set do in other service diagnostic situations. Don't know why they demonstrate this using that kind of single gauge setup. And yeah, it seems like you should purge air with a bit of refrigerant into the line to the gauge before proceeding. Most of this should get sucked back into the unit as the pressure goes to zero. Thus, loss should be very little. That's my theory anyway. It's nice they tell you how to do this. It's a rather elegant solution if you want to replace an air handler or move a unit!
How do you not understand that the single gauge used in the video is the same as using just the low side of the dual manifold gauge?
Valid point on the slight purge.
Wow, this trick is sort of a game-changer. This means that I could install a single unit in my house, and then later transfer it to my exterior garage if I were to upgrade to a double (or triple) zone unit. Is there a similar procedure for recapturing the refrigerant in a multi-zone/circuit system?
Right now, I am strongly considering purchasing a Pioneer, but I'm still undecided. So far, evaluating the differences in (heating) efficiency between models has been discouraging. Further, accomplishing a top-quality DIY is somewhat daunting. In either case, it's nice to know that Pioneer has a CZcams channel and actually responds to comments; every bit of customer support helps, so that's certainly a mark in your product's favor. Thanks.
I did a DIY install on my pioneer unit and have been going strong for five summers with a bit of spring and fall heating use as well. I just ordered a new four unit to expand on my house. I am gonna be using this method to remove my old one and install it at my parents house. They have treated me good so far.
@@janellemariedunkle did you use their flush kit or a compressor pump to vacuum the lines?
*This unit works like a charm. Keeps my room 20 x 20 very **Fastly.Cool** . I recommend to anyone that wants to keep a room cold without having to turn on the main a/c.*
Great job 👏
Thanks a lot!
U the man
Is it a big deal if you forget to purge the line going to the gauge before doing this process ? Jus did mine an realized I didint purge it an not sure if I’m screwed now? Thanks
I have heard it said on other video's that this pump down procedure be done on units that use R-410a regfrigerant. Since this is a Pioneer video, and the unit they are pumping down "" to be a new Pioneer mini-split that would typically use R-410a refrigerant, is it safe to assume that it is okay to do this pump down procedure on Pioneer compressors that do contain
R-410a? I wouldn't want to ruin a new compressor should the need arise without being sure.
Quick question, what is the yellow hose attached to?
Thanks for the video.
Cheers from Tokyo!
Nothing. It's normally used for charging or pulling a vacuum. In this video, he's just using the guy m gauge
If you have air in the system will it get drawn it also?
Why does this say to open guage valve? Wouldn’t that let Freon into the manifold and won’t it read when closed
Why is the gauge valve open, I don't understand that part of the process?
What can happen is that pressure sensors will stop the compressor from working under certain conditIon and design so you would need to force the compressor on.
Didnt purge the air out of gauge hose so it got sucked into outdoor unit. Right?
How is this done on muti-zone models?
I have a pioneer 18k unit with a 40’ linset that I added additional r410a when installed. I want to move the unit to a different location because of a remodel. Will the unit only hold the amount for a 25’ linset when I pump it down or do I need to buy a tank to store the additional coolant?
That's only another oz right? It should fit.
Here we go again. 9 of 10 videos on YT are missing a very important step - purging the hose before evacuation…
How do you re intall it when you have moved it elsewhere? Do you have to evacuate the lines then?
Yes, you have to do a complete install when you reconnect it in the new location.
If I have a 3 zone mini split do I need to do this for all 3 lines?
i’m wondering same thing and procedure in service manual only shows for 1
how much refrigerant is lost in this process? is the compressor able to pull a vacuum?
If done properly, there should be little to no loss. The compressor cannot pull a vacuum, this process should only be done on a system that has already been evacuated and refrigerant released into the circuit.
The yellow hose in this video is useless. It either needs to be blocked or removed. The open side of the gauge (on the left) needs to be closed with 1/4 in brass flare cap in this case. You will loose the refrigerant with this particular gauge otherwise.
You are absolutely correct! I did this and the yellow hose did leak even though it had a Schrader valve. Thank you for the information! The cap size you described is exactly what you need!
Now if you want to reinstall the unit do you need to vacum it before releasing the refrigerant?
Yes, if the circuit is unsealed meaning the lines are exposed to open air then you need to re-vacuum. This process is essentially returning the unit to uninstalled condition.
What if it's cool outside (50 F, say) - will this still work ?
It worked for me and it was 49 degrees outside yesterday.
Can this be done on my dual zone mini split from pioneer?
wondering same thing cannot find answer
Where can I get a gauge like that

Is the yellow line just a loop? Not connected to anything else?
Correct.
It needs removed and capped! Pioneer should have told us this!
Real informative video! But where does that other end of yellow line connect to?
It doesn't... I had the same question. Check the video titled "Haier Ductless Mini Split Refrigerant Pump Down". Same idea but rather helpful.
Remove and cap it or it will leak.
Make more HVAC videos
My guess is that the other end of the yellow line has a Schrader valve on it to prevent coolant escaping. My yellow line has one. And those are the same valves on the unit itself that prevent the coolant from leaking out when the cap isn't on the unit. Probably very minimal coolant lost into that valve's tubing I would guess.
The coolant will leak from the yellow line. Cap it! I know because I just did this and it leaked. This video needs reshot.
How do you recover the R410-A from a Pioneer mini-split when the compressor is inoperable, and the entire outside unit must be replaced but the inside unit is operational ? Is there a video that shows the recovery process when the outside unit must be replaced and there is just the one service port ?
You would need a recovery tank and a pump
Are all or even most mini-splits, using R410A? Is there a different process for the different processes?
@@riggsron no and no
let her spew, who cares
this will save a marriage if this worx
Shouldn't you purge the blue line before attaching it?
No need. Unless you have pressure in your gauges the pressure in the system will push in to The Gage. The gage will not push anything in the system
@@drodriguez394This is wrong. There is certain ammount of oxygen in the blue hose. Once you connect it the refrigerant from lines enter the hose and mix with oxygen. At the end of evacuation the compressor makes a litle bit of vacuum and sucks everything in including content of the blue hose. If you didn’t purge it after connected, now this is in your system. So correct method is to attach the hose while the system is off, open valve on a manifold for a very short time and then close it. Now the hose is purged with refrigerant and evacuation can start.

Technicians have been ripping me off every time i need to move my split units. you pay them for freon and service
Like, seriously? You said nothing about the discharge line! The discharge port has to be CLOSED before you turn the AC on!
Not really. You can close discharge port while ac is running. Not a problem. Also it’s better to connect gauge hose on running system since pressure on suction line will be lower so you have less leak on connection. Also one should not forget to purge the hose before evacuation!
Thats a pumpdown, not a “recovery” method
So when the gauge valve is open the blue line is open and the yellow line gets closed?
I this how the yellow line is not letting the pressure out or is it caped some how?
You need to remove and cap it or it will leak! It is used in the vacuum process.
