My thoughts and prayers out to you Miss Kate!!! Hopefully the dark clouds soon clear out and the sun comes a shinning through!!

These are just guesses with the info you gave, what is the differential setting? (if it is wide could still be in range).
Is this controlling supply or return water temperature? Hopefully it has...

The Freon name is actually still alive and quite well.

Looking at picture #2 those stub outs look like they could be a type of orficed check valve. Restricting hot gas just enough to keep compressor happy. I guess controlled by suction pressure or temp....

If memory serves me right, I think Data Aires had the copelands with the rotolock connections. Mabe?

Hi davem, would you please shoot me a copy also. TIA!

Can you post the series and model number for this?

Yep They all had nicknames. Even us techs/mechanics. We were the primadonnas showing up on the jobsite wearing uniforms, clean cut pocket protector all ready for critique or praise of our fellow...

When I was cutting my teeth the journeymen used the term" Stupid Wire Pullers". This was for all electricians.

Dad, sorry this is coming so late but I am very sorry for your loss. Prayers and well wishes to you and your family for the future. And also a big thank you for your effort of keeping this site the...

X2 for sure.

Where does she dance at??:oops

Besides checking the oil screen and sump for pieces, don't forget the muffler if it has one. I once had a Carlyle that busted up and sent small pieces into the muffler and rattle canned that thing...

I am with taheem on this one. I learned thru trial and frustration to cut the valve out first. You can bench weld the valve at once and have room to get good flow around the joints.( Even on top of...

Fan Curve, your 6L45 is actually a 06L209 Carlyle semi hermetic 4 cyl. based on the 5H open drive compressor design. Three cylinders will load/unload. If your vibration is coming after your last...

Hi there Carbon. Do you know what the actual equipment was they were rigging onto that floor? Lots of guessing as to what exactly was being lifted. Curious minds want to know for sure.

Congrats Chase!! May his life be happy and blessed!!

On that compressor you can't just turn the center head around. You will need the proper center head whether front or rear discharge.The head suction/discharge separation casting is different for that...

Had the same thing happen some years ago. luckily company stepped up and replaced everything like for like or better. Try to push your company to step up to the plate.

Looks like Aggrekko Blue to me.

My thoughts and prayers for a full and speedy recovery for you Mr Bill!!!

I really feel bad for your son. I do hope that he will recover soon. Look at the library pages on this site, maybe an answer somewhere in their docs.

Don't be so hard on the poor guy... At least is looks like he left some nice cardboard diagrams for you to follow!!

A lot of Lieberts with the motor master option use a 460v single phase motor for speed control while the other fans are three phase.

You are correct rundawg. Thanks for the lit.

That unit is a 50QQ heat pump. Serial number says 1982 Those ranged from 1.5-5 tons.

Looks to be 25 ton chilled water upflow.

See if this works. I can't get my word program to open to see if the file is good.

with that low of amperage you should be fine. They probably used #12 solid for wiring. Just verify your actual voltage and size heaters accordingly. It would still be best to make this just a...

Looks to be 1962

Check with samsung. I know that fujitsu sells high humidity insulation kits for their cassette.

As others have stated, snubber capasitors.

Did you verify the condenser fan motor was spinning correct rotation? A faulty capasitor can cause it to spin in reverse. Or is it just recycling hot air thru it since you said it had alot of...

Dad, since the OP has now apologized can we get this thread closed. No need for others to pile on...

Actually you were correct with your first(Shorted) post. I have a diagram but can't seem to upload it. Looks as if you have it handled though.

my guess is that there is a motorized fire damper in each supply drop in that combo plenum. They would all be daisy chained together, spring return closed with loss of power to them. Another reason...

I am glad this was finally mentioned!!! Good call PHM. Also something to add, not knowing how much oil has been added over time I would assume that the refrigerant is "oil Saturated" not enabeling...

Need more info, Model# are these ducted systems,downflow,top plenum discharge?. They come with adjustable sheaves from the factory.

I also remember using R11 to flush out DX piping on larger system installs.

Just to use as a reference, The trane voyager uses the same blower wheel from 17-25 ton units. Not the same fan rpm as your system(still need to provide M&S numbers...)

If the compressor was insulated and the mud and moisture rot makes me think that thing sat under water at some point in it's life.

X2 Here.

Had this sitting around on the HD. Figure better to share.:putergreet:

Good thing is that it looks like there is enough room to raise that thing and build a return platform. Definitely falls under
hack category...

No schematic on one of the panels? Are you a tech.? Don't want to come across as an ass but this is 101 stuff. The transformer label should tell you what those leads are(primary,secondary). We can't...

My mistake...Foot in mouth syndrome:whistle:

Have you verified your run cap is good? Could be causing compressor motor to labor more.

Give this a try

When i was cutting my teeth(mid 80's). If we came across a R500 Carrier they had us size down the TXV
2-3 tons smaller and then charge with R22.

Here is some PSIO info I had.
