My bad, went to the I.O.M. gotta sight the oil level off the end of the motor cuz it acts as a sump too. Tried to upload the IOM

I've changed many a RTHB oil filters, I have never drained that much oil unless you also drained the oil. No need to change the oil unless tests shows nfg. Now your gonna hafta add 2 gallons of oil....

I see alot of motors. I haven't seen any trend on Long Island, plus my 10 yrs in NYC. If the motor failed, I'd be looking at incoming power to be honest.

Thanks all for you insight in how you recover low pressure systems. I reviewed the original EPA regulations, although no direct mention of 24 hr monitoring is mentioned; in good faith one shouldn't...

I use extra tanks too to relieve the pressure but you dont use a portable purge?

This is not a general low pressure recovery question. I would like some clarification on leaving L.P. systems on vapor recovery overnight. I think the law says it must be attended 24 hrs, for example...

In regards to stacking liquid. The optimum liquid level on CVHE & F's is 1/3 below the weld line on the condenser barrel. Unless of course there is a VFD. Then all rules go out the window. I agree...

That orifice we speak of is not nearly important when a machine is leaking. It can be cleaned with some wire to clear the hole. Bypass it on start up to get rid of winter air. If after 3-6 hours, the...

You can isolate only the oil pump. You can let the oil drain from the sump valve by the two glasses in the transmision section of the compressor. You won't lose that much ref. When it pisses vapor...

It's Balzone. .. funny. Scuffing definitely keeps the gasket from flowering out. Any1 work on duplexes in a box. Trying to figure out how to take it apart without taking the box apart. The guy who...

The chiller is fixed. Thanks all 4 ur input. Checked the ref pump pressure to make sure it was pumping. The new AFD setting help in overcoming ref migration (which is not a factory bad design, just...

What is I just put a purge unit repiped just to make the drive be nice and happy?!? :)

Condensing temp was 71 F. Temp going into drive was 81 F. Attributed it to the oil sump heating up the refrigerant. Thinking the refrigerant pump is dry. It does ramp up to 60 Hz and then opens up...

Working on a 600 ton HF with CH530. Has an AFDE I believe. Forgot to check the nameplate b4 I turned it back on. Refrigerant R-123 cooled. Took all the gas out cuz the purge couldn't keep up with...

Not quite an engineer, just a wrench turner like everyone else. But I do get to give input. Which in it of itself is what we all wished we could do isn't it? As for the lipseal/slide valve/ piston...

Yeah the butterfly valves on the suction are indeed a problem. Just to let everyone know we're working on it. Prolly gonna move everything back to the compressor as it should be.

It's not a poor design!!!! They are damn good machines. It really bugs me when people say stuff about Trane product like that. We mechanics go once a year to seminars where we get to give input on...

it's funny how we're required to look for ourselves how much it weighs, instead of the guys in the office already having looked that up.

I would concur. Unless for some reason those flanges didn't look crooked a bit. Sanding down the flat rubber gaskets works wonders. 515 works pretty darn well in the new O-Ring'less units. The...

You refering to the oil filter element?

Laughed my arse off. Too funny. I'm going to use this technique next time I pull apart a CVHE with a newbie. Just jam up a twig between the suction cover and the evap.

Overhauls are awesome because you can write all kinds of stuff about supervisors on the inside and only you and your partner know. Unless of course you open a machine up and find someone had already...

we had this problem but the newbie wouldn't get in the unit

what kind of nuisance trips are you getting?

It's a recip economizer.

I think it sounds like elephants in heat. Had an absorber guy with me one time while a 1500 ton CVHB did that. Darn guy got so scared he ran out the room.

Had something like that happen to me once. Was distracted by the customer and left a rag in the liquid elbow on a PCV after finding it leaking on a simple oilpump change out. Confused the crap out of...

put a turbulating liquid subcooler on the condenser outlet.

sorry my diatribe was too boring for you

That's a really good question. I would think less because less work is being developed on the motor because of less airflow. Come to think of it, It has to be less, especially when you think about...

Definitely agree Randy, dis-colored copper is never good. Always clip back my motor connections. Good pick-up.

I'd steer clear of 4160 equipment too.

Had to start up 2 80 ton units this summer. Darndest thing. One had all it's pressure controls switched on the wrong circuits. Took a bit of head scratching and wire tracing to figure that factory...

Those meg readings don't sound so hot to me. When was the last time the bearings been changed?

No Vista support yet. Better that way anyhows.

It's not likely it's leaking back thru the prv. The jacket is your best bet.

When you closed loop, is it a regular valve or a pressure reducing valve that feeds it? Incidently increased sytem pressure does not increase flow. It does balance out the fluid to a more laminar...

copper spun driers don't have enough dessicant in them to be true driers. More of a prefilter. Shouldn't be a problem as long as you pulled a good vacuum on it. Trane does usually allow suction oil...

I like just having an apprentice unscrew it. They're always so eager to do it anyway. They are the new blood of this industry that has grown leaps and bounds since the 60's. Don't like the Taylor law...

how much?

we were still soldering these in the field only 5 yrs ago if the compressors didn't blow yet cuz of dirty coils on the first RTAA's. lol.

You're absolutely right. That's why I ask for thumbdrives and email address's whenever I am on site. So I can upload all the manuals for their machines. Anyone who works for the factory that thinks...

I bought this 11in1 just because. It was like one better than 10in1. I truly did.

good ole 515. we got an old timer nicknamed that cuz he used so much when it first came out it got stuck on the IGV's. He still laughs when I call him that.

Yeah I'd say that cherry syrup is a good bet. Regular good ole blue LeakLock works just as well.

how are the terminals connecting? with an o-ring? describe.

cool. takes time with a global corporation to have everyone agree this is the format and the software structure to manufacture machines to sell all over the world with a support system already in...

No offense taken brother. I thoroughly enjoy this forum for the give and take of information. I always take the time to make the owners and mechanical contractors I meet are up to date with I.O.M.'s...

Stickerhead? ...nice. Don't me wrong. I have alot of respect for my firms competitors machines. They make good machines too. But my friend I think per chance you might be wrong about market share....

are you done complaining? .... seriously? what you didn't see what we are making? Hint. These machines with Adaptaview have their own internet address. We're trying to introduce wireless machines....
