- In this video, I explain how a 9 lead semi-hermetic compressor is wired. I go over across the line and the two part start wiring and what components you need to wire it correctly.

great info.
Don't see too many of these out there anymore but I hoped that these would help someone out there. Thank you! And thank you for watching!
I APPRECIATE YOUR SIMPLE BUT INFORMATIVE EXPLANATIONS.
Thank you!!! I try to keep it simple so it is easier for everyone to understand!!!
Thanks 👍
Thank you and Thank you for watching!!!!
عالی 🙏🙏🙏💙💙💙💙💙
Thank you! Thank you for watching these videos and I hope these help you become a better technician out there!
Great explanation Julio...Thankyou for passing on your knowledge
First class Julio, really appreciated
I'm so glad! Thank you!
Please explain Star delta connection of motors and the uses of both.
I'm not sure if I have one of those videos, but if I don't I should make one for you guys out there. Most of the time we don't see the star Delta connections but I will keep this in mind! Thank you for watching!
Thank You Teacher Julio I love NAPE school in Alexandria Virginia
Thank you!!!!
Great instruction on why we hook line power to L1, L2 and L3
Thank you!!!
Great work and knowledge. I would suggest theory with practical, if possible for better understanding. Thanks.
Thank you! I wish there was a way I could do some practical. That is just so difficult to do when you're making videos. When I teach a class I like to get the guys to actually do what I teach for real on a bench or on an AC unit. Sorry this cannot be like a virtual reality game lol if I could I would create classes so you guys could reach in there and do things like you would out in the field.
Thank you for another fine video.
I know I'll have to come back q this one for a refresher when the time comes, but now I know "it's there" .
Great reducing - "only 3 types of motor electrical problems."
(Post n rmbl?)
I like simplifying my life. And have reduced the problems down to only three. And if you think about it we can reduce most electrical problems down to those three. Even if they are inside of a circuitboard. Good luck out there and thanks for watching!
How to change oil in blitzer AC compressor without vacuum pump
I will be honest with you, I don't know if that is possible! You first need to close the suction valve on the compressor to isolate it!!! Then pump the compressor down to remove the pressure inside the compressor. Close the discharge service valve. then get the oil out. After that, you will need to pump New oil in. You will most likely get air into the system as you pump the oil in. It is this air that needs to be removed by the vacuum pump. If you. Do not evacuate you will leave air in the system. As far as I know, it will be next to impossible to pump oil in to the compressor without getting some air into the compressor. Good luck and thank you for sending you questioning.
I like teacher Julio I
Thank you!!!! gad you are watching these videos they help a lot!!!!
Thanks for sharing the knowledge
Yan Heri Herlambang I am glad you liked it!!!!
Great job!
Thank you so much I appreciate your comments!!!
So valuable information shared..
That was very good thank you Julio
Thank you!!!!
Sir please another video about humidifier thanks and god bless sir
I will try Thank you!!!!
i dont see where there is a delay. your feeding the contactor and the auxillary contact at the exact same time coming off you t-stat.
oh I see what you mean. Remember, electricity travels at the speed of light. Was one contact her holes in it is going to pull the auxiliary contact in. That a lot of times is enough of a time delay. Other times there is a timer that is used but it said to one or less than one second time delay. And when you actually see it happen you can see the time delay. I hope this helps.
thank you for sharing...
You are welcome!!! I am glad I could help!!! If you can let me know where you are from?
I'm from philippines. Your videos help me a lot.
@@greatvampire2919 Good and thank you for letting me know where you are!!!
What a superb video. Really helped. Would you please be able to make a video of Star and delta connection? Also is part start the same as part wind? Just different terminology?
Yes, basically that would be the same thing. And thank you for your suggestion I should make a video of wye and Delta connections and maybe going from as you call it star to Delta. Or another words wye to delta.
Hi, really good video, thanks, just wondering can you talk about ERV unit?
Alan Wang I will make a note of this and see what I can do. Thank you! Thank you for the suggestion
how many seconds sir approximately the delay on that set up of designed?thank you
In the past I have said that to 1/2 of a second or one second. Remember electricity moves at the speed of light so even one second is very slow of a time period. But that is how I have set them in the past. I hope this helps.
thanks a lot sir.more power to you
#sir please one another video make on hvac part winding (delta) cannection .
i will see what I can do. Thank you!
Sir some chiller unit no write RLA , then how we will to calculate RLA in part winding cannection
It's ok to put delay timer??
I have seen timers used but it has to be a very short timer so you do not have a long time delay.
@@AirConAcademy ah ok,, only split of second?? For the delay.
Hello Sir i am new to your channel i liked what i watched already very much i have a question if you may how dirty condensor affect superheat and subcooling and why
It is a long explanation but I will make it a short explanation. The condenser gets rid of the heat. If it is dirty then it cannot and the pressure increases. Because it increases it pushes more refrigerant in to the evaporator decreasing the Super-heat, when you have a fixed orifice metering device. The subcooling will drop. I hope this helps a bit. Glad you like my channel and hope you subscribed.
Thank you Sir for your reply is it possible to have a video clop on how superheat and subcool get affected when charge or ambient or airflow change and why i still can not understand why subcool is high when i system is overcharged and so on appreciate it if that is possible or doable by the way i subscribed after watching the first clip because i can tell that you know what you are talking about God bless
Thanks sir you are really great,but I have some doubt in this cannection my compressor have six terminals and 440volt, that's why my compressor 4,5,6 terminals winding inside compressor.......? And doubt no.2 I was watching some unit 2 contractors amps showing same, and some unit 2 contractors amps showing different. So I am confused...!! What to do? please tell me sir 🤔🤔🤔🤔.
Suppose one contractor 60% another 40% amps according RLA.(same chiller unit)Why its happen on hvac compressor part winding cannection .
YES!!! some will only have 6 connections. Like I said in the video there is not enough time in that video to cover all of the different connections. there are motors and compressor motors that will have3, 6, 9 and 12 leads or connections. The ones that have 3, and 6 connections are only one voltage, whether it is 208 or 480 volts and you cannot change it. The reason you have 6 leads is so you can wire it in either Delta or Wye configuration. The 9 and 12 lead motor or compressor you can wire them for low voltage 208/230, or high voltage 480 volts. As for your second doubt, The amperage is lowered only on start up and you will NOT see it as the motor is running. I was talking about the inrush current. witch only happens for a a split second and that is only at start up. I hope this answered the questions you had. There is a lot more that I did not go over, here or in the video, I talk about those in class but no time here I am sorry, but Thank YOU for watching and asking questions!!!!
