might have to sig this
"It's a little heavy for that... but what the hell, might even lay the sausage on it..."

anyways is the noise sound like if you put a drop of water on a super hot pan? MY first ever unit from sneil made this noise. It was overcharged, im sure its nothing though. The temps will tell, little compressor noise is fine :)

funny you describing the sound like that Spliggity, my SS made the same sound, but then again it ran at 36C+ at the evap head on wprime LOL.

very interesting
he walked me through taking some refrigirant out, I took too much out then had to add some propane and then it was fine.

That is a sign of flood back, liquid referigent getting into the compressor. If that is to bad it can damage the comp. or shorten its life.

If it happens while no load is on the unit, and only a little then its not to bad. But if its still doing it while a heavy load is on thats bad and shows it is very over charged.

Does this unit have an accumulator on it ?
I wil have to look back at some pic's to see if you show it.

Ok I see now, it does have one installed.

A accumulator is designed to catch liquid refrigerent in the suction line before it gets to the comp. You should be getting no flood back at all with one of these.

this makes sense... did your compressor get really hot? mine starting to cook, and the coil coming from the condenser as well....

Coming from GA to KY might be the problem... elevation difference maybe?

something to take into account as well for sure

Yeah compressor was pretty hot if I recall, had to add a fan to the backside (was in a smaller encolsed case though so that did help the situation)

Compressor that get super hot are out of tune and working very hard. Its like sitting in a car with your foot on the gas and reving it up. While a well tuned car traveling down the freeway just cruses along just fine.

What makes them do this ? To much pressure or operating in a vaccum which is prolly the case. This is done at times to get much better load handling but at the cost of reduced life span of the comp.

All comps get hot, that is not a problem, but super hot means its running in a vaccum, I think anyway.

My SS from Jinu and Kals 2 stager, never make flood back noises and make almost no noise while running. Kals 2 stage comp does get warm and a fan on it is all it needs. Its nothing to worry about tho as its in temp range. But the loudest thing on his 2 stager is the first stage fan on the condensor. Metal fan blades tend to make more noise.

Hmmm... might need to bleed it a little then and see what happens.... If that doesn't work... I'll have it leak tested.

Running in a vacuum does what? How is that corrected, at least enough to get this thing running better?

Only way to fix it is to tune propper.

DOH!
