Copeland Compressor Oil Change

Called back to change the oil and filter drier in the rebuit compressor after about eighty hours run time.
You can see how dirty the drier core looked compared to the new one.
It pays to use a torque wrench when doing the cover bolts back up to ensure there are no leaks at the gasket.

Hello guys. I have missed watching your machine rescues. I lost some sites when I had to transfer my favourites into the new phone. God bless you folks.🥰🤩🤩🤩🤩

[@heavydiesel]

Welcome back!

[@FixitFrank]

This is one of my favorite channels. Thanks again for all the quality content.

Hi Nick, I would pump down the system and then lock off the disconnect/isolator, shut all the service valves. Make a note of the oil level, i use an old refrigerant tank and pull a vacuum on it to suck the oil out with a thin tube, and hand pump the oil back in to level noted earlier. Core drier depends on model, some have more than one core, but there is instructions on the can, make sure the gasket is good/clean in the end plate and use a torque wrench on the bolts when refitting,

[@raviyadav8743]

Sir, where do you connect Vacuum pump for sucking oil.do you connect in compressor suction king valve? Plz let me know

[@HVACShopTalk]

What a great video! Little things like driers mean so much to a system.

[@JamesPettinato]

Copeland recomends that when you install a suction vibrator eliminator you install it paralell to the crank shaft. When it's installed perpindicular like this one is, it gets jammed together when the compressor vibrates up and down. It will be alright for a while but it will eventually fail. And you know Murphy's law, it will be Saturday night.

[@gregoryclemen1870]

you are 100 % correct on that one, all vibration absorbers are to be installed parallel to the crankshaft of the compressor, also the oil level should be checked with the compressor in operation!!!

[@heavydiesel]

Its an old disposable refrigerant jug, i drilled a hole in it and brazed in a 1/4" fitting. I pull a vacuum with the vac pump on the original tap and have a tap and some small bore plastic tube on the new fitting to feed into the compressor sump. I could do a vid of the set up if you are interested :-)

[@heavydiesel]

If i remember correctly this one runs on 4gs mineral oil (or iso68 equivalent) because it has a mechanical oil pump on the compressor. I think your compressor is splash feed lubricated and would likely use a 3gs mineral or iso 32 grade poe oil depending on the type of refrigerant the system has in it. Best to check with Copeland, the wholesalers tech department or even a good compressor rebuilding company for advice. If poe, Emkarate RL-32-MAF is a specific oil for Copeland compressors.

[@heavydiesel]

Its not normal to have to change the oil in a new or replacement compressor, but this system has a history of dirty and contamination so thought it worth changing. The dirty is not normal either, its wear metal and burnt winding from the previously failed compressor! Oil should still be nice and clean in a 20+ year old compressor so long as nothing has contaminated it.

[@MegaRadio90]

Very interesting!!! Whoa that drier core was mucked up pretty good wow.. Love the video's and seeing different thing's

[@eagletek1]

What are you using to draw the oil out of the compressor?

[@heavydiesel]

Hi Axel, Here are a few things that can cause trips on low oil pressure, 1, Crankcase heater failed 2, Low oil level 3, Worn bearings or oil pump 4, Blocked filter 5, Oil dilution due to liquid refrigerant during running 6, Oil dilution due to liquid refrigerant during the off cycle 7, Wrong grade of oil 8, Faulty oil pressure switch 9, Compressor tripping on other control then oil pressure switch tripping I expect there are other causes too, i don't work on many systems with oil pumps!

[@71dembonesTV]

Great Video! I like the idea of your oil canister; I would love to see a video of that set up, too. They told me in my textbooks that I couldn't do anything with an old refrigerant jug except scrap it! I like your idea better :D

[@AliHassan-ic5ow]

good answer Mr Hd I agreed with u

[@JamesPettinato]

yeah..down there a tobacco farmer gets off a tractor puts a can of refrigerant into an auto AC then thinks he's a tech and goes into business. I remember seeing new AC units placed on top of the old worn out units, double stacked.

[@ChumpusRex]

So are you supposed to do an early oil change after commissioning a new compressor? Is that sort of crap meant to come out?

[@heavydiesel]

Hi Naveed, I have a Refco 21702 oil pump which fits in the oil can and pumps the oil back into the compressor. If i don't use that then i pull a vacuum on the compressor and put a hose in the oil can and suck the oil in that way. My video "Copeland Hermetic Compressor Oil Change" shows my had pump at around 4 minutes into the vid.

[@laaireacondicionadosas294]

Hi Heavy ,,,, very good explanación mate ...what camera do you used ? What make ? Very good resolución !!!

[@heavydiesel]

I think this was shot with a Flip camera but Cisco stopped making them, most of my recent stuff is done with an iphone5

[@danielalonsomartinespedraz1652]

Hola tengo uno de esos lo conseguí para mirar si puedo hacer un compresor con el

[@heavydiesel]

Think all comp manufacturers recommend vibration eliminators are inline with the crank shaft as i'm sure you know. Its not perfect but we did what we could in the time we had, the original install had been done with plumbing solder and the original vibration eliminator was bent into an 'S' shape as the pipework didn't line up! None of it is clipped so at least its free to move... It all wanted re installing with the condensing units outside, i believe the system has been replaced now with new!

[@heavydiesel]

Yes there has been a few burnouts on the system, plus it was piped with plumbing solder and flux...

[@heavydiesel]

You will need to check for leaks on the plate and sump plug etc, then vacuum the system and compressor, once it has reached a good vacuum let the refrigerant back out of the reciever and open up any service valve still shut e.g. head valve. Then you should be able to run the system keep an eye on the oil level. I don't test the oil quality, on this size of compressor its cheaper to change than send samples for testing. Depending on country you may need certification to work with refrigerants!

[@Samlol23_drrich]

How often are you supposed to do this?

[@heavydiesel]

On smaller compressors there is no need to change the oil unless it gets contaminated as in this case, they'll run 20 plus years on the same oil. Bigger compressors 15/20hp plus have service intervals depending on make and model where its recommended to change the oil every so many thousand hours of operation. If in doubt check with the manufacturer.

[@Samlol23_drrich]

Thanks very much for the response. I have a 2 head KAT4-100 compressor and never did a full oil change. One head is running hotter than the other and is tripping the breaker only sometimes. Gotta figure out if its the 20 year old breaker or 20 year old oil! Gonna change em both. Thanks.

[@heavydiesel]

Wow! what do you think made them go completely black?

[@JamesPettinato]

I lived in Myrtle Beach for a couple of years, I met a fellow installing some equipment, he thought vibrator eliminators were "flexible elbows"

[@tuqeerahmad7652]

I need some help . I have changed the filter of same this unit . but after that plant in going choking after 5 mints . please tell me what is wrong with it?

[@heavydiesel]

What is blocking the filter? This system had a lot of metal particles due to previous failed compressor failures.

[@rainermuller7399]

Hallo .What for a Oil you fill in ? I have a DLFM 201 .Sorry for my bad english

[@nickmiller4544]

I enjoyed very much your video, could you describe the proper procedure to change out replaceable core dryer and oil? does it need pump down first and pull a vacuum after that? how do you test the oil quality beside the cleanliness thanks

[@Samlol23_drrich]

How are you getting the oil to flow out of there? Definitely not gravity

[@heavydiesel]

I have an empty disposable refrigerant cylinder I have brazed another port onto, use vacuum pump to pull vacuum in cylinder to suck the oil out of the compressor.

[@Samlol23_drrich]

@@heavydiesel thank you that's great

[@Fakhrealammm]

Hi heavy, can you please elaborate the wiring made to this compressor? does it have pump down timer when the temperature is reached? the temperature sensor is connected to the compressor directly?

[@heavydiesel]

On this system the thermostat directly controls the compressor (via a contactor). When the system needs to cool the thermostat sends a live feed to the low pressure switch, high pressure switch, thermistor module, and overload relay, if all these safety devices satisfied the contactor will energise and run the compressor, the solenoid valve opens when the compressor starts. This is the factory wiring for this system though i believe it would be better if the thermostat just controlled the solenoid valve and the system pumped down and turned off via the low pressure switch.

[@Fakhrealammm]

heavydiesel Hi thank you very much and happy new year. i attached a pressure gauge to the suction side and noticed when the set point temp is reached, pump down starts until 0 psi pressure is reached and after that the system shuts down. i really don't understand the wiring. can we talk over [e-mail], i will send some pics of the control panel as well. i really want to understand the wiring of this system.

[@geraldnerves8577]

What grade of oil is recommended for this type of compressor

[@heavydiesel]

I am not 100% sure on these as they have an oil pump, I think its 4GS if mineral oil which I think is a 48 weight POE, the non pumped ones its 3GS or 32 weight. Best to confirm with the agents or a compressor rebuilders.

[@mohamedwaliddoussa7464]

Hello Everyone, I have a problem with a compressor emerson copeland D8SJ1-6000BWM / D. mounted done me a lot of oil despite that I changed segmentation! I will like to advice from you thank you for avanace

[@heavydiesel]

+Mohamedwalid Doussa I am not too sure what you are asking, maybe something got lost in translation. If the compressor oil level keeps dropping it can be there is liquid coming back in the suction line. It can be due to bad valves in the cylinder head, it can be due to a bad oil separator or blocked oil filter. Also if the crank case heater is faulty it can make them pump oil out when the compressor starts from cold. Sometimes different makes of oil do not mix well and make foam which gets pumped away. There are other thing too than can cause oil problems.

[@charperr_935]

Hello, I have a copeland KAJ3-0075-CAG. its about 15 years old. Doubt theres been much done as far as service. Now its short cycling on low pressure. I can see the liquid line sight glass is full as well as the raw water heat exchange. soon as I turn it on the pressure drops until it turns off, which takes about 1 minute from initial start up. Also I see your compressor uses mineral oil? Can I use the same oil in my system. Running of R22 right now. Thanks

[@heavydiesel]

I'd suspect a faulty expansion valve or other restriction given the symptoms you describe, though lack of flow in the evaporator would give similar results. Mineral oil is compatible with R22, though some compressors use alkylbenzene oil for R22, best to check with the compressor or equipment manufacturers if unsure.

[@jeffleblanc8850]

I see you use mineral oil I have a compressor from Italy with the refrigerator style compressor and they say to only use sincom 32 oil and it is quite hard to find any body with a alternative thanks

[@heavydiesel]

Your compressor would use a different type of oil as it is compressing air, this compressor pumps refrigerant so the oil is never exposed to oxygen or moisture. I would think an equivalent 32 weight air compressor oil would do. Also might be worth having a look on Amazon or ebay for the correct oil.

[@jeffleblanc8850]

Do you use mineral oil cause you are running a pump to

[@Soad614]

Hi bro, i have a question. How often or when is necesary a oil change, like a normal service. Like oil change in cars. Thanks

[@heavydiesel]

Hi Julio, on this size of compressor there is no need to change the oil unless it has become contaminated some how. On bigger compressors there are oil change intervals, some big Frascold compressors we used to look after got an oil change every couple of years for example.

[@Caterday1234]

When changing that style of filter dryer do you need to pump down the system before you open it?

[@heavydiesel]

Tim Gomes Yes, you need to pump it down, though in big commercial systems i have seen them piped up with shut off valves and a bypass so the filter can be changed without stopping the system. If i get a system with a big moisture proble i will put a shutoff valve after the drier, that way i only need to vacuum out a small part of the system.

[@sancolorado]

you didnot show us how you put the hose the size of hose how much cubic cm .

[@bblazeff1]

was there a previous burnout?

[@mdrajibsarder1640]

Oil Great?

[@bblazeff1]

i just replaced a few cores last week that were completely black, like charcoal.

[@nognogskiful]

very well explanation

[@heavydiesel]

Thank you Gary!

[@FrontSideBus]

I can just imagine what would happen if it didn't have a filter drier...

[@ificandoityoucandoit6507]

Thanks!

[@axeloropeza2827]

Hello mr. heavydiesel, i have a discus copeland of 10 hp. and it is cut off, i check this and push the button reset of the protector of lubrication and then start again ,in some times run for days with none problems but in a hour wich i dont know again is stop. if you can help me i apreciated to you.

[@FarmanAli-mw2nw]

Very good idea

[@Fakhrealammm]

hi heavy, i have copeland semi hermetic comp, the liquid line is quite hot compared to the other compressors of the same model. can you please tell me whats going on? the compressor catches frost sometime as well. setpoint temp is 4'C. i can see bubbles in the sight glass.

[@heavydiesel]

Hi Fakhre, A hot liquid line is a sign of a dirty or undersized condenser or faulty fans, or possibly the system is working very hard, either due to high air temperatures by the condenser or high heat loads on the evaporator or a combination of these factors. (assuming its an air cooled condenser) There will be other things that can cause high liquid line temperature but that is what i can think of now!

[@Fakhrealammm]

thanks and sorry for the late reply back. the man culprit were condenser fans, 2 out of 4 are controlled by high discharge pressure and hence kicks on when pressure is high. changed the danfoss kp5 sensor and its good now.

[@naveedchakwal1959]

hi i cont see how u fill oil in compressor

[@Fakhrealammm]

what is the purpose of the short flexible pipe ?

[@heavydiesel]

The short flexible pipe on the oil removal tank? Its the end of an old gauge line, it was easier than making up some 1/4 copper!

[@jonathanoxlade4252]

how much from 1 to 10 on how overkill it would probably be if somone bough a 70hp compressor semi hermetic and used it for PC phase change cooling well it's got more than enough grunt to hold sub zero temps

[@jonnymac31]

What brand torque wrench is that?

[@heavydiesel]

Its an older style Britool one.

[@jonnymac31]

heavydiesel right on thanks

[@reksdb]

my problems is electrical scheme for copeland 25hp yy/y.thanks

[@heavydiesel]

Hi Dejan, I don't have any information for that model, try asking Copeland themselves, or your local wholesalers technical department.

Burnouts, neglecting to change filters after opening system to atmosphere, not adding acid away after burnouts. I don't know. Probably the original cores. Lol ..
