ADDING OIL TO HVAC / AC COMPRESSOR

- adding oil to the AC compressor.
an important factor that most technicians overlooked, compressor oil levels, some compressor has oil level sight glass and others the only way to check oil levels is to disconnect it from the system and drain all oil contents. In this video the compressor has a oil sight glass and typically the level should be between 50 to 75% of the glass. Also information about compressor oil will most likely be on its name tag. - แนวปฏิบัติและการใช้ชีวิต
Thanks. Never added oil before this was short and to the point.
Thanks for watching
Good job
What kinda of brand this gauge
Do you have to close off the suction side of the compressor always to add oil to the system on a rack
If you are adding oil directly into the compressor oil port NO!
If there’s no oil port do you add it from the high side(liquid line) ?
how would you add poe oil in a 410a 25 ton package unit that has scroll comprressors?
Through the oil ports on the compressors!
Using an oil pump!
Can you pump in the oil directly to the compressor without using the manifold gauge? Can you hook up the yellow hose directly to the compressor oil port and just watch oil level on sight glass?
Sure you can
can you add POE oil through equalizer line on rack system or do you have to use suction port?
Any port that’s on the bottom of the compressor can be used or if there’s none go through the suction on the compressor
@@D2DNYAC if u filled oil from the suction side .. compressor running or off conditions sir
Compressor running and add it slowly
@@D2DNYAC ok thanks for the info mate 👍🏻
Thanks for watching
do oil added circulate along with refrigerant in the closed loop?
Some of the oil in the compressor circulates with the refrigerant
ok sir thanks your vidio , i will try ,if have problem i am ask you
Nice one
Great video. Do you have to
Pump system down? Or just turn system off and pump oil in.
Pump would make it easier to add oil because of low back pressures but no I didn’t pump down
Same job i also do today..
Awesome 😎
can u make a video on how to diagnose the compressor to know it was low on oil
Typically you can tell by oil low level safety alarm or by viewing oil through sight glass on compressor or if your system has refrigerant leak and along with that a huge puddle of oil
sir add oil , kompresor running or off
Off
What about air in the oil/hoses?
Purged it with oil so that it’s filled with oil prior to connecting it to system
@@D2DNYAC thank you, do vrf compressors have an oil port? Is oil change a thing in vrf work?
Can we reduce the oil level by remove little bit of oil in the scroll compressor so oil level can drop?
Sure you can and with this compressor it’s easy
@@D2DNYAC how to reduce it ? Do we need to disassemble compressor for the system?
@@D2DNYAC the system use danfoss scroll compressor..the blue one
Said simply "level line anywhere in sight glass"! Thats how they work, if its below the glass you don't know how far below, if it's above the glass you don't know how far above! Some where in the glass, you know right where it is! Also is there not a lot else to know here? If it's a charged system how do you not contaminate it? Guessing you must have to prime the pump and lines by pumping through all the lines involved back into your bulk oil until there is no air bubbles? Why cant you just use any pump? Guessing that the long narrow Yellow jacket pump with its long stroke and low displacement has the ability to manage, check and over come the static system pressure so you can get oil into a pressurized system? Why would you use a manifold to pump oil? Im just a dummy DIY AC guy that does some install and repair of ac gear in my own business and was looking for info on adding oil on 4, 5 ton systems based on line set length. Still on the hunt for that info!
Not just anywhere in the sight glass, typically 50 - 75% up is okay, yes must hose first to remove air prior to connecting! You don’t have to use a manifold a hose will do just fine!
