- This is how to make a refrigerant recovery pump from an old compressor the real ones cost $500 and up. You can’t release refrigerant into the air.
How to wire the compressor new video
Added a start switch
• home made vacuum pump ...
I like the down to earth simplicity of your video. Just explaining what I need to know. Thanks!
Thanks for your comment I try to keep it simple for people that are looking for useful info
Excellent. Thank you
Well done, and recording the entire process on yiour phone takes a special kind of patience
Great and helpful. Well explained I may build one I will be working on old monotor top ge refrigerator
This video helps me alot...thanks for the video
Glad it helps.
I have been looking for a video like this thank you for sharing your knowledge
Nice work man now you just need the certified stickers to stick on the discharge and charge areas to make it look official" so no mistakes happen down the road
Great Video my Brother!
I made the same setup but trying to recover refrigerant compressor keeps locking up and trips the internal breaker. It can do vacuum perfectly goes to 30” and builds pressure over 450 psi. But when trying to recover refrigerant it shuts off.
You know you said you can't release refrigerant into the air..... I agree with this. BUT, every HVAC tech does it every time they connects gauges and recovers slash AC work. And all these new gasses "claim" to be safe for the atmosphere.
hello, would you recommend adding an oil separator to the feed line of the compressor? thanks.
Great and helpful
Glad it was useful thanks for watching
A pretty good video. You forgot to mention to purge the lines at the recovery tank and close off the Manifold High Pressure line not being used. However I learned enough to know how to build one now. I would also have liked to know what port you were tapping on the Refrigerator Compressor. Thanks so much for doing this video. Thumbs up! Best Wishes & Blessings. Keith Noneya
Ya i think i need to make one of these i have a mini fridge that i punched the line inside that i haven't thrown away because i planed on pulling the compressor for something like this ir an air compressor
A compressor uses oil in the refrigerant for lubrication and the compressor will have limited life without oil. The object is to liquify the refrigerant and compressing it will make it hot. You need to cool the output to condense it to a liquid. You also need a filter-dryer before the compressor to protect and clean the compressor and make the refrigerant reusable.
You need some gromets for the copper lines going thru the toolbox to hold them tight
THANK you
Please show how to wire compressor, does it need a capacitor to start ?
Here is the link to the video on how to wire it

Put a condenser with fan and changeable filter drier in line and you get better results.
Nitrogen back purge when brazing?
Good morning
Yes I like the video but I would like to learn more about Refrigeration. I would like to build a setup like you have ok. Could you tell or show me where I can add freon in a refrigeration if I can do it myself & save money$💰too
I'm calling from Houston TX. Oh keep up good video on here too
Is there any concern for oil coming out of the compressor and entering the recovery tank?
There’s always risk but it’s minimal
Wouldnt it recover the lowside gas only
Hi, will the tool box vacuum be able to pump the refrigerant liquid ? isnt it a piston pump ?
Hi. I have a question. Can i make a vacuum with this pump ? I not have a special pump to do this. I would like to suck all air from the system. I mean system in fridge of course. System in the fridge have fe pump, condenser, vaponiser, dryer filter, pipes, capillary tube and other elements. Thanks for help.
Yes you can use it as a vacuum pump. It’s not as good as the store bought ones but can be used run it about an 1 hr.
@@appliancerepair420 Thanks for the answer.
Well done.Can you use this machine in all HVAC,residential and automotive.Thank you.
You can but for cars you need the adapters for your manifold gauges
I heard the ELOTERO MANN😂😂🌽🌽
is it possible to pump out compressor oil with this method? im thinking of ways to fully replace my car compressor oil without detaching compressor from the car, i heard vacuum pump wont pump the oil out 🤔
You might get some but not much.
I know this is a few years old, but can you give me a source on where to get the Schrader valves of the size that will connect to the standard hose set used for residential AC units? I don't know what size/thread type are used. Thank you.
For refrigerator the size is 1/4. Not sure on ac. I think for example mini splits with 410a are 5/16. But not sure. Amazon is a good place to get them
@@appliancerepair420 Thank you for the reply! You were right. 1/4 inch. I found Pack of (6) C&D Valve # CD3605-1/4" Access/Line Service Valve with 5/16" Copper Tube Extension so I only need to braze or silver solder the copper pipes together. I just need to find an old window AC to pull the compressor out of. I have a couple old non working refrigerators that that I use as fireworks storage lockers but I don't think those compressors would be large enough. They will run, just don't cool anymore so make a good sealed storage locker.
Hey by any change are you in Orange County California?
By the way I am enjoying your videos!!!!
Is that what the OC stand for?
Yes I’m work south Orange County Irvine on down all the way to San Clemente
Nice, thank you! Does it matter what type of compressor to use, from a dehumidifier, refrigerator etc? It the compressor usable for all refrigerants?
The bigger the compressor the mor suction power you have. This is meant for smaller appliances like refrigerators. You should use it on the same type of refrigerant that the compressor had example 134a because it might contaminate the pump and might go bad.
@@appliancerepair420 Thank you very much!
Is this epa compliant
What vavles I will need post a part # an size please
It’s 1/4 inch APVS-14182
old refrigerator compressor vs old window unit compressor? Which is more powerful.
It comes down to horse power most refrigerator compressor are 1/4 or 1/3 or 1/5
It needs to vacuum and gets rid of air in the pipe for blue, yellow, red, and compressor itself, at least. Otherwise, air is get into freon tank and pollutes pure freon in the tank. I recommend the commercial one, not your idea.
You are right but my point is some people don’t have a vacuum pump and are diy so this is better then nothing. That’s all
Would recommend this for scavenging refrigerant from systems, and not venting them out to atmosphere. not to be repurposed.
maybe put in a switch and put fitting out top?
Funny that you mentioned that just finished a new video where I did that.
ua-cam.com/video/1jIZuT46UpM/v-deo.html
It's possible to use for auto?
Yes I’ve used it on my car a few times
where did you connect a red hose from a high side of the manifold gauge?
Ok so the blue goes to the the compre that is on the refrigerator. The yellow go’s to the the suction line of the homemade recovery pump. And the red would go from the discharge line on the homemade recovery pump to the recovery tank
Hope this helps
I want to make a fully functional recovery machine for Auto airconditioner please guide me
What type of capacitor was it that you used? What is it used for. Or is this just the start capacitor from the unit the compressor came from? Thank you and great video!
It’s the capacitor that was on the compressor when I removed it from the refrigerator. It helps lower the amps on it.
If you have to explain how to hook up the suction/discharge lines. They will not know to purge air, nor prevent oil contamination.
Just trying to make it as easy as possible.
The compressor has 3 ports. Could you please explain their functions?
The one on the left is the port to install the service valve for charging and to check pressures. The Smaller one (high side) is the discharge line that one pumps the refrigerant into the condenser. The fatter one in the back is the suction line (low side) it sucks the refrigerant back to the compressor from the evaporator. Hope this helps
@@appliancerepair420 suction port in the back or in Rt.side of the compressor where a yellow hose is attached.I think port in the back of first compressor simulate the source of gas from which you recover the frion but what it's function in the second compressor that you made as recovery machine?
Instead of filter dryer,can I use refrigerant identifier to make sure if pure gaz or mixed wither gases
I use a filter drier not sure of anything else but possible
@@appliancerepair420 Waiting for next video.Thank you.
Please use knee pads always 😇
Thanks will do.
Hey how can I contact you
