- Recovery method, the most commonly used method but unfortunately its the slowest method.
Refrigerant safety basics and recovery refrigerant from a complete system.
next video will be a faster recovery method.
the slow method is good for when customers are standing over your shoulder trying to get you to drop you flat rate price for repairs in half :) Ya just tell them these procedures take time :) flat rate is flat rate.
Very professional instruction. I liked the way you illustrated it. Standing behind and allowing everybody to clearly see each hose and how it was connected. Very clear. Thanks.I gave it a thumbs up and subscribed.
Ty and Jay combined will make an Hvac master!
You're Awesome! Why do people act like this is so difficult to learn? You're an amazing instructor. I've been trying to learn about HVAC on my own for the last 2 years and have learned so much from watching your videos. I am very confident in myself doing a recovery, and pulling a vacuum, I have always had electrical troubleshooting experience from working on hot side restaurant equipment, I just wanted to be a HVAC tech but couldn't afford school, Now that I know what I know, I'm glad I didn't. I have become Universal certified from watching your videos and studying on my on. I have come to the reality that I'm 50 years young and no one will probably ever hire me in this trade. However, Im going to keep learning because I love this stuff! Lol... Thank You!
Awesome!!! I love hearing that.
Don't sweat the age, lots of people out there looking for someone just like you. My oldest student was I think 70's got a job at a supply house.
Thanks for the feedback, it made my day!
Thinkers often have trouble working with physical things. When people don't exercise their tactical function, their mental process for doing so fails them. Because of this, I think it's important to work with tools.
A/C work involves critical thinking, and hands on.
I'm 61 and learning. My first repair is a 2 year old humidifier recharge. It was $250 from Menards and can't throw it out.
I don't know about EPA regulations, but european F-gas regulations require a more involved process for recovery, since you aren't allowed to purge. It is still not massively difficult, but requires a bunch more steps, so it is technically easier to get something wrong, and you need to remember more steps/info.
Don't know how this is handled elsewhere, so I can only talk about requirements in my country, but perhaps that is the reason why people consider learning this more difficult than it seems in this video
cool- didn't note whether you needed to pull a vacuum on the tank first.
Thanks a lot man. I found this Very helpful.
Bigger systems, energized crankcase heaters and turn all chilled water pumps on!
Thanks again for the videos!!!
They also make safety sun glasses! 🕶
🍺🍺🍺🥃🥃🍿🎯
Stay safe.
Retired (werk'n)keyboard super tech. Wear your safety glasses!
Thanks Ty! I just graduated today from NTI and I’m glad you can still continue to teach me.
Congratulations. Never stop learning!
Thanks for the video
I recover in a scrap yard and get the least mess from recovering from the liquid line only and vapor line shut ! If it gets really hot and hi pressure I use the very cold bath actually with ice and I put the whole recovery tank in the iced cold bucket!
Best teacher
Perfect 👍 ✅
With that g5 if you need to restart the pump under pressure and not remove the hoses, close your manifold gauges then close the inlet valve to equalize the recovery machine then slowly open the inlet valve and reopen your gauges. Also to get rid of liquid after your recovery. Close your gauges then close the inlet valve with the pump still running. It will recirculate what is in the pump and super heat the liquid, let it run for 30 seconds then close your tank and shut off the pump, you shouldnt have any liquid in your hoses.
G5 Twin should be stored with both valves open and no caps on the ports. If caps are left on then they need to be left loose so pressure won't build up.
💯 absolutely without a doubt put caps on. For sure have the valves open and leaving them without pressure is important.
Appion says to use the caps don't let them be airtight.
The contaminants, moisture dirt, dust and bugs wreak havock on the internals. The ones I rebuild that use caps are always much better shape internally than the ones without.
Especially when recovering with Poe oil. The moisture turns it back to an acid and that just puts away the anodizing coating. It does much more damage than the >15 psi vapor that that builds up inside even with a tight cap.
Nice video. Why we did not see the manifold red hose purged? 🤔....
To avoid purging the red hose with liquid refrigerant I would open the manifold low and high valves and purge the red hose at the condenser port. But wait you can't do that with low loss hose!
This is one the reasons why I always use ball valve hoses.
The only reason is I feel i covered purging manifold guage set hoses pretty thoroughly in past videos. So I clarified this example the manifold guage set is already attached and purged at the manifold.
The auto low loss fittings are a restriction and I do agree the ball valves are much better also covered in several previous. For many students starting out recovery is overwhelming so auto low loss is one less thing to worry about while they build their confidence.
There are many many problems with this method much beyond the low loss fittings. Check out the 2 videos to see much better and faster ways.
Hi Ty! Is this machine can handle some liquid because the service valve for liquid line is open? How can the liquid flow to tank if there is some refrigerant in the tank it will push it out?💐Thank you.🌷
Great video. Do you have a tutorial on charging the system from a recovery tank? Will it be a short or long process? Thank you.
When you purged the air from the lines - having the high side closed would leave air in that hose, would it not?
I've never liked purging, it's a guessing game as to when the purge is complete - a waste of refrigerant if it's too long, or allowing contaminates into your recovery tank if it's too short. Put a core removal tool on the recovery tank and use it as a valved tee. This allows you to use your vacuum pump to very quickly pull all the air out of all the lines and your recovery machine. Only takes a couple minutes
I like that!
@@love2hvac I use the same valved tee method on my refrigerant bottle to vacuum my lines and guarantee no contaminates go into a new or existing system when charging
A vacuum pump doesn't pull a complete vacuum like people think. There will still be air, just less of it. Maybe 1/10th as much. That may be acceptable. It depends.
Thanks for this. I’m not a HVAC Tech but I’ve been taking care of my own R-12, R-134a, and R-22 systems for 40 years. I’m hoping my 40 year old R-22 heat pump will hang on until the switch to R-290. 🙂
I was wondering about using a vacuum pump for this. “No” ok good info.
5:46 you open up the liquid side too. Is any liquid coming out going to flash to vapor before it gets to the recovery pump?
8:19 you note ice - remaining R-22 in the oil - are we talking 1 oz or what? I don’t have a feel for whether the ice is just remaining after, almost, the last bit of R-22 flashes or if some remains. I see the gauges at almost zero. Is it worth waiting for it to flash to vapor, relieving pressure on the recovery pump, and pump the last bits to the recovery tank?
Thanks again.
Thank you
Thats rad! Very clever. How much would it be per tank?
good method if you dont feel like working so much. Just let the thing suck and take a break
What did you use to calculate the capacity of the tank
Thank you Mr. Ty. Is possible to use only houses with ball valve with out using manifold gauge? And is there time for replacing filter drier for recovery machine? Thanks.🌷
Yes your going to like the next video.
I should have clarified in the video. The one I'm using is not an actual drier it's just a filter. It lasts a good while depending on how contaminated the system is.
I use a true drier when I have to put the same refrigerant back in. I will use 2 new driers. One when I recover and another one when I put the refregerants back in. I rarely reuse refregerants but in those cases the cost of the one time use dires are worth it.
What happen if u have 410a in a recovery tank use an vacuum that gas to replace with another is it possible
Hi does recovery machine come with accumulator? If doesn’t, why can’t cause slugging compressor? Since to recovery the liquid? 🙏 thanks
What if the service ports are only on the suction and discharge pipes?
The last table, I didn’t understand. The number 4 and 10 are inches of Hg vacuum?
Yes that is correct
Wouldn't there be trapped air in the liquid line? Beginner question
You have the right idea, there would be, but in this case he purged the gauges before the video started. He states this at around 1:40
Hi, does this recovery also takes the oil out of the compressor? So if I want to add new refrigerant to this same condenser wouldn't the compressor lack oil? Great video. Thanks
Some oil will travel with the refrigerant depending on some variables. It's usually not enough to cause a problem with the compressor. Unfortunately there is no sight glass for the oil level of the compressor in residential.
When the system is up and running you can check suction superheat and discharge superheat. When they are too far apart it's a sign of lack of lubrication.
Thank you for this video, I have a question - can I recharge my AC from the R22 recovery tank?
Yes
The method used to purge air from the circuit, vapor, is possible because it's a pure gas.
Thank you for your videos!
What if I did reclaim from liquid just wondering
I am learning Mobile HVAC . I don't find many pro level (with theory) videos like yours for automotive which is why I'm here . I have an older recovery machine Robinair RG3 with no purge knob. Manual says to remove refrigerant out of condenser in machine after you finish recovery operation to prevent possible damage to machine. Manual just says transfer to another container. How would this be accomplished? Thanks for any and all help Ty
I have the same problem with my RG410... after the system is in a good vacuum my recovery equipment has backed up liquid liquid refrigerant at high pressures... Manuel says to turn off equipment; set the recovery equipment to the purge setting and re-start. This does remove 95% out of the recovery equipment but not 100% Ty mentioned using the purge setting on initial hose set-up. My equipment seems to purge fine with dial set at recovery... Now one gets stuck with a hose full of liquid refrigerant attached to the recovery tank :)
Were you using the light as a heat source on the compressor?
I was just trying to light it up to show the ice formation. I have another video that I talk about hearing the compressor up to speed recovery.
Hello mr Ty. I know my question is unrelated
Would you be able to do step by step wiring on old school all mechanical heat pump. Thank you for your time again.
I will, it's just talking a lot longer to get these done than I expected. Trying to do them all between other work and job.
@@love2hvac
Thanks. All I do in my work is troubleshooting on just residential. I did have a call for just replacing wifi T Stat. Some other company brought 120v to T Stat and I had no idea. When I put t Stat face back after finishing wiring. Fried the t Stat. Then I put my lead between C and R I'm reading 115 volts. I went to package unit. It was a mess. Tech had 120 volts hooked up to R low voltage T Stat. What the hell. He fried the board.shorted everything. I had to re wire everything and put universal board in.
Videos on transformer especially on power supply 208/240/120 how to get hooked up to the board is critical. This is 3rd calls throughout this year I come across. Lots of new tech do not understand how to hook up power supply for transformer where C or 240 goes. on package unit. End up blowing things up.
Thanks again
I plan on doing a though wiring segment just like I am doing with the HVAC fundamental series.
It's been a lot of prep work and I expected to have it done by now but so much to do.
@@love2hvac
Wish live close by that could have helped .
Why did you connect the last pipe to the vapor side and not the liquid side?
So the liquid will drain into the tank when it's complete. If it's attached to the liquid side you will lose all the Refrigerant in the hose because it can't push past the straw in the tank.
See the other videos in the series for much much better and faster ways of performing recovery.
Thank you
Can this be done with a ac vacuum pump in place of a recovery machine?
No, it will damage the vacuum pump
When you demonstrated that you loosen the red hose and raise it in the air so the refrigeratant drips into the tank wouldn't it get contaminated with air?
No because the hose is sealed so air does not enter.
@@love2hvac thanks for replying! I appreciate it
It looked like you didn't purge the liquid line, did I miss it?
Always purge.
Was the compressor running?
No
5:33
If this is the slowest, then why is it also the MOST used? Do most people love to wait? 🤔
Ignorant. Note ignorant is not a bad word it just means lacking knowledge or awareness on a subject. We are all ignorant in things. Any learned from one person and just repeated it to another.
The lack of understanding a faster recovery is also one of the reasons many people choose to vent refrigerant. "Recovery takes too long" is what many people say.
Wait, what happened lol. This video told you basically the slow way to do it and then he says at the end, "next let's talk about how to speed this process up"....and then the video ends 😂
Wtf? 😂😂😂
Cliff hanger! To be continued 🤣, it's I'm editing now. It should go live on Monday fingers crossed.
@@love2hvac ohhh ok LOL i look forward to it
why would you need gloves?
I personally don't use gloves but the official OSHA EPA answer is buytal lined gloves.
