Yes, I can explain it to you, but I shouldn't have to.
My reply might seem harsh, but this isn't the sort of question a pro would ask in a commercial HVAC forum.

Its not a centra vac those are low pressure this is high pressure, maybe taking a trane class is a good start.

i always hated the series R chillers being named CenTraVac (Centrifugal Trane Vacuum). nobody seems to know why.

Thanks! You are the first guy told me CenTraVac (Centrifugal Trane Vacuum). I guess Series R using same control panel with centravac. Do you know why using Series R instead of screw. Originally Posted by jayguy

I got this story in 1991. Originally Posted by txhvac

Do you have any literature on the equipment? Get RTHA-IOM-1A from the Trane website. You will find your answer in the manual. Why are you adding charge? Like the rest of the fellas, I'm concerned on why you are servicing equipment that you MAY not be skilled enough to work on. I think if I were you, I'd be discussing w/ the powers that be at your company,that they need to set aside some finances to send their mechanics to factory schools. An RTHA is not like a Voyager, there is a LARGE difference in compressor costs. Originally Posted by greasy hands

ouch!!! a little harsh on someone with two posts.how about a little bit of an answer so he can see its not so cut and dry. maybe he will come back .
and before all those "dont want him to kill himself" replies come flying at me.
i know, uh huh,
greasy hands if you cant find the nameplate charge and weigh it in, and you acnt figure out superheat, subcooling etc. dont do it!!! and if you are not EPA certified dont do it.
hope thats a start to make up your mind.
