 Welcome back guys I got another video for you this is one that I recorded in the beginning of 2019 you're gonna see how I convert a semi-hermetic compressor over to 134A from hot shot I believe originally it was probably R12 but this system here when I showed up was void of refrigerant and was cycling off the low pressure switch to find the leak I went ahead and pumped it up with nitrogen the nitrogen that's in the system is the pressure that I'm also going to use to pooch the oil out and there's several different ways to get the oil out on a semi-hermetic compressor you can use the same pump that I use to pump the oil into it to actually siphon it out I've also recently picked up a little hand pump for like 10 to 15 bucks from AutoZone where you can stick it down in there and just self primes and pulls the oil out which is a real simple way of doing it also if you have any questions for me on the video feel free to either email me or leave a comment down below if you look down in the notes section you'll see my email you'll also see links to my tools that I use in my videos and several other things there's a little arrow just click on that it will pull it down and you can actually see a lot of the things that I'm asked for generally it's all there just scroll down at the bottom and all the links are right there let's go ahead and get started all right the compressor was short cycling on and off on and off on and off and wasn't really much free on worthwhile to keep and unfortunately it's 414b so I seen the oil down here more than anywhere that's where the detector was picking things up at but it looks like I didn't have enough pressure to do a quick search here and make sure well that's where I kept picking up with my detector boy we got all kinds of freaking leaks only good grief got on both nuts yep just mainly those two nut busters there I'm I suppose I could try tighten it usually when a boils down to it you've all got to just redo the flare we'll see if we can't tighten it up and see how it does yeah I'm going to go ahead and convert this to 414b right now I'm gonna put a new filter dryer in I have to take the oil out it's a be oil front seat valves a little piece of copper in there seal around the spout there where the oil be filled in and the pressure push the oil out then we'll pump in the DOE oil I tightened up the flare fittings I need to get my soap and go back in there and see if that sealed it up they were pretty loose that we're going to front seat this valve so anyhow we got the quarter inch line it's going all the way down in the bottom got her going down in the oil okay well I put a cap on it that way the pressure don't come flying out there we just want a little big bit not much I build up pressure and I'll push it all out easy sleazy is that cool I'm back one hand we got our POE oil here I've had this thing for 18 years and barely ever used it because I didn't do a lot of refrigeration after I bought it and what it is perched a little bit of my hose got all the moisture and crap out of the hose that's in there and now we're gonna pump it in all right we got the hot clean benzene oil marked out our 134a got that sealed up we just sprayed it we got 200 pounds against the suction side so that's never going to see that much pressure so it's sealed and we got the top of compressor just labeled as POE we just kicked it on went ahead and weighed three pounds in to kind of get it started and obviously it's gonna shut off but I'm gonna add some more to it just cleared the site glass six pounds 11 ounces doesn't look like it's very big but I'm gonna let it stabilize for a second see if I think stays solid I'm gonna add between 10 and 15% to it it's warm back here right now because you have all these heaters but you know there's a good chance to that this big old monster door here to be left open and then it'd be cold as it is outside which would put us under charge so we're gonna set her up just like you would if it was outside unit okay our pressures look pretty good and a nice solid site glass we got seven pounds five ounces was a lot of calculated out to be in everything's labeled properly we're gonna test to make sure it pumps down and it doesn't go into a negative and I got to check that inside TX-V oil's okay right where the other one's at it was higher earlier when I was actually starting it up I overcharged it it's moving around a little bit just to come back and double check everything right right now we're 15 those my bypass tube is really I should see equalizer tube is really letting some through we're definitely feeding I'm just gonna watch it for a bit because it was a little higher earlier very easily to be hunting around it's hard to say but I'd like to see it maybe closer to 10 area I'm gonna wait for a good jump in the gun we got to back it out counterclockwise if you're looking at the stem towards the head making a couple small adjustments and she just did a nose dive down to zero and then came back up I went ahead and took about a quarter of a turn back back out jump back up to 10 so she's a sensitive little burger it's 33 in here I have 11 degrees super heat it was a 10 earlier somewhere between 8 and 10 the norm because it can act stupid and change on you I'm gonna go ahead and just stop there it's obviously gotten down to temperature we're gonna call this thing a day it's time to go home and obviously it's working so there was 10 again so before I end up causing it to go wacky and certain all over the place I was moving her in super super small increments and waiting for a while wait for a while I've noticed you cannot rush it I didn't believe it but I'm telling you what you will believe if you go jumping too quick because it seems like you put that bound into a freaking frenzy and she will take forever to settle back down alright the defrost clock was set at like 40 minutes a little lary about changing things but I went in just took it to 55 I'm like 60 minutes twice a day and I went in set the clock then I made sure on the thermostat that I marked where it was at before I moved it lined a pointer up to the thermostat and I put it right back to where it was one thing I've learned as you change anything they may notice it and then they call back even though there's nothing wrong alright hopefully you enjoyed the video I want to thank everyone for sticking around so long I've got a lot of different video content that I want to release and different things that I want to show these videos for me are just a way I can try to help a lot of the new guys I know a lot of the guys that's been in the field as long as me already know a lot of these things and I'm not saying I'm the best or I'm the greatest or anything like that and you know I get questioned all the time why are you even doing this and to be honest with you I really enjoy the satisfaction of being able to help somebody you know when I first started out I didn't get a whole lot of help from a lot of people and either they didn't know or they didn't want to tell you and I think that's one of the stupidest things I've ever seen in my life the insecurity of not wanting to help other people if you're trying to better yourself by watching videos online that's great you know more power to you there's no reason not try to become better at what we do I watched the same videos you guys watch in hopes of learning a new trick or or an idea on how to do it if you like to do you please like share and subscribe leave a comment down below give it a thumbs up if there's something you liked didn't like by all means either email me or leave a comment down below once again I want to thank you guys for watching until next time we'll catch you on the next one
