P.S.
I have rad and posted in the Hussmann Haters Subject. I have lived with Hussmann here in the SF area. This is where all of it seemed to start in the early 1990's

And no offense meant to anyone here....


Bryan, I agree with him.

Besides, if you really want something to gripe about, go read what I just posted on Husman Haters.

Redd does need a friend, and that was my point. He came to the site and asked a question. He deserved an honest answer to his question. If the answer was a step by step on what to do, fine. If the answer was you don't know enough about what you are doing, get help that is fine too. I just think it is inappropriate to give advice, even if it is in sarcasm, that might be misunderstood as fact by someone who seems to be in the dark about what he is doing. This is how people get hurt. I know that when I was new in the trade, 28 years ago, there were people that liked to play pranks on the newbies, and I fell for my fare share of pranks. It is a great way to learn from your peers, but i think that the advice given by Bryan crossed the line a bit.

I will try to lighten up some, but I enjoy what I do and take it serious when I have to....

I think you and I share a common interest in trying to share the facts of the trade.

Refer dude, lighten up.
So far Redd is happy with us and why should you or anyone else make him feel differently about us?
What purpose would it serve?

He's happy. He doenst feel insulted nor shold he. He hasnt been insulted nor is he likely to be ... if we all keep it easy and light.

This is crap!! If you can not give good advice aboput how to do something, then give no advice at all. I agree that this guy should not be working on this compressor, but I do not think that telling him to do something that he might not know is wrong is correct. Someone could get hurt. And it might be your fault. Maybe this guy is new to the trade and his boss has sent him to do something he knows nothing about, but he can't afford to tell the boss no. [/B]

Its sarcastic. This guy should not be touching the compressor AT ALL!!!! He may get hurt? Hell lots of people can get hurt if guys like this screw with things they should not be touching. And why cant this guy ask the Boss? Afraid to admit he does not know something? How about when he craters the compressor by doing something stupid, how is he going to explain that? This trade is not one you learn from your local Home Depot store, Trade school AND on the job training is the only way. NOBODY here should be telling ANYONE how to do anything this basic. This is how the REAL hacks come to be and hurt other people. I pride myself in the fact I help others when they need it, and ask for it. This type of thing is WRONG!

Add it slow and do it with the compresser running so you will see your running oil level...good luck.

Ned you are quite right. I am amazed every time someone says to pull the plug on the compressor and add the oil there. Even if the compressor is empty and you can not run it you can add oil through the suction service valve slowly until the oil level is correct. The suction cooled compressors have a check valve that lets the oil drain right into the crankcase, and the compressors that have suction returning right to the head have a small venturi tube that allows oil to enter the crankcase. The only compressor I know of that chargeing an empty compressor through the suction will damage the compressor is the Cralyle 06E body compressors. The motor cavity is not equilized with a check valve on these and the oil must pass to the crankcase by flowing through the suction cavity in the compressor. If you charge one of these through the suction while it is off and then turn it on, they take a big gulp of oil and make a big bangging sound

Now how you fill the oil is to take the 1/4"plug out of the side of the head (its the one in the front almost pointing forward.) make sure you pump as much as possable in there. Then you have to prime it by "Bumping" the compressor until the oil will freely flow down into the compressor. At first this may sound really loud, but keep doing it. eventually you will learn you should not ask these kinds of questions online. These BASIC questions should be answered by your Journeyman, or local Fridge guy. if you dont know... dont touch.

Hello again, looks like the compressor is low on oil.
I still don't know where I am supposed to add more oil.
I have narrowed it down to one of the two 1/4" plugs.
Can someone please share their EXPERIENCE and offer some advice.
thanks

Thought I would throw in an update.
Very cold, -10, I'm happy with results.

Thanks for the overwhelming support, till next time...

OH MY GOD... PLEASE CALL SOMEBODY!!!! should change your name to "Parts changer"

Yes I know, it's a stupid question. But I did not remember exactly, and wanted to make sure. I see only two 1/4" plugs, one is about 2 inches above and to the left of the oil level sight glass, and it has a 1/4" flare going to the pressure control. The other one is on the side with a 1/4 flare (schrader connection). I assume you mean the one next to the oil sight glass. Otherwise I think everything else went allright. Up and running 2 days now. Freezer won't drop below 15 F. Now the pressure is at 7 and 195. I'll be putting on a new tev tomorrow, that should help. Also new filters, again. Maybe the low oil level also is a factor. Yes I did go through the blank off plate, and the oil got just below the 1/2 mark. My experience is in industrial controls and electric, but I got enough success stories and experience to be confident in my abilities to do this project, despite the fact that I may overlook something time to time. I appreciate the help.
"Bumping" the compressor, you mean letting it run 10-20 seconds, then off, repeating several times, right.

Gonna be hard to fill to 1/2 a sightglass through that blank off plate.

I didn't TELL him to take the pressure off the pump first, relax.

It's NOT FAIR!!!


This guy hasnt been sprayed! He should have been sprayed!

You guys prevented him from entering in thru the rights of passage by getting properly initiated ... ie; getting oil all over his-self as well as everywhere with a fifty meter area around him.


Now... no one will ever believe he is one of us, simply cause he has never been sprayed, (initiated) properly.

No, that's a sightglass port. Your sightglass can be installed there or on the side.

The oil should be added throught he suction service valve.

Brake cleaner preference is: whatever is cheapest.

Thanks again, the oil is now drained.
On the side where I drained the oil, there is a round plate, held by 3 bolts, looks like the same diameter as the oil level sight glass, and same height. Is that where I add oil?

And thanks superdave, I will try out the brake cleaner. Any brand preference, or is it all the same?

The 2 bolts is it. Kind of a oblong plate about an inch and a half wide?

thanks, If only I knew where the oil pump was....

The oil level sight glass is on the bottom right of the front of the compressor (the side with the nameplate, model # etc.), a few inches to the right, around the bend I see a small cover, with 2 bolts. And to the right of them 2 bolts, another bolt which copeland has labeled "external access crankcase heater if specified".

Am I getting close?

It's under the oval shaped plate.

The plate needs a new gasket once you take it off.

Behind that plate are a spring and a screen. You SHOULD clean the screen with either Virginia #10, or, my personal preference, brake cleaner. (Yes, the stuff available in auto parts stores.)

Make sure you put the screen and the spring back in the way they came out. This is important.

Now, all that said, and please don't take this the wrong way, but I have my doubts that you should be servicing this thing without experienced guidance, if you don't know what the oil pump looks like. Is there a refrigeration tech in your area you can call for guidance while you work on this? Any mistake can become an expensive one...

Good luck, and let us know how it goes.
