I feel like healy totally meant to say SCARY in his spelling

if the oil level gets too low, this can occur. Had this issue, same style but with 134a. This machine has the tstat as the only thing that will cycle the oil heater, when the chiller is off, the 1R...

what kind of rise you expecting on a 12 hour test?

call trane parts. give serial number. replace entire canister and old ball float with new style capacitive sensor.

anyone have a list of what versions support what? I have "Chiller Basic" ver 8.4.310 and it does not include Retrofits to RTH chillers or Duplex.

does it allow retrofit to RTHA,B and C? How about a Duplex retrofit from UCP2?

Got a couple of complete sets, pulled out of two CVHEs , all three mods. PM if interested

Always

I sent you a message, check at your leisure, thanks

anyone here do an RTHA adaptiview upgrade yet?

supertek, do you think you have a crossover leak on that system?

Thanks Joeyd, i will call you tomorrow. Ice, i have used the CPS and a robinair thermistor with needle gauge.

Joey D,
Have not read through this entire thread, forgive me. I have a bluevac that I bought earlier this year and like it but have had an issue maybe you can help with. It seems like since i...

Supertek,
Are the compressors in question loaded or unloaded? the current imbalance tends to get worse in the unloaded condition. Are you tripping at the UCP on current imbalance? what is...

even us straight techs should have a say in this maxster

john
yes, you have to isolate liquid into the condenser and let sit for awhile then compare to ambient

thanks jay

Saturation dew point pressure in this case is the actual suction pressure. The temp in front of it is the converted , corresponding evap temp. Kind of confusing. For instance in the first...

I am glad to know that even guys with 30 years under their belt struggle with things too LOL. About 20 years for me and can't believe what I dont know, all the time. Anyway, I will say this;...

Got a Voyager, YCD241E4HNAD, ser# 112410787D. R410a machine, two stages of cooling and gas heat. stage one has the dehumidification option and has a hot gas diverter valve that looks like...

great advice there, funny I am the only tech I know that double flares, supply houses dont even carry kits

Are you refering to the liquid line sight glass? I don't recall any sight glasses on any Trane screw compressors. Are all circuits going out on HP, or just one? How many circuits...

I also like high vacuum grease. The edge that Nylog has over that grease is that it is oil and will be totally harmless if it enters the refrigeration system. That said, I would still use...

have you tried contacting copeland?

you made a good move josh

Took a nasty wire wheel cut to the hand last year. Was wearing gloves, but not too protective and the grinder bucked and ended up with a few stitches and a conversation piece of a scar. Luckily that...

Is this machine making Ice by chance?

I will make a suggestion. For the price and portability, you cant beat the dtek techmate. Do a little research and ensure you have the sensor that comes in the blue pack and you will be able to pick...

how far away from Portland are you? always loved Maine

thanks for the update

this is a very good tip. Had a large centrifugal blow about 1000 pounds of R11 (ouch$$$) and the offending area was near an exhaust fan as well

ordered the blu vac and got it quickly, thanks. Cant wait to try it out

r404a

are they looking at feloniess or felonies and misdemeanors?

Absolutely not

242 should be used on the inner stage nose seal bolts. 567 Loctite will be ok for R123 as well, but 554 is specifically designed for refrigerants. Found that 567 on r134a systems cant hold the poe...

loctite 554 for pipe threads

Knew york,
regarding these evap temp sensors: I have noticed on J style optiview YT AND a g style Optiview YK that these refrigerant temp sensors do not match up to the saturated conversion...

that condenser approach seems quite high. You can get real close on charge by looking up the shell codes. Maybe those higher discharge temps are with the vanes closed and makes sense since you state...

TF
Also wanted to ask this: Can you get the liquid line temp along with the discharge pressure and discharge temp as well. Condenser leaving water temp also at the same time. A high subcool...

TF
it is better to get a refrigerant sample on a flooded evap from the evap itself, as oil content can be drastically different from a running highside refrigerant sample. Concerning the water...

TF you would be right in saying the AI is not an issue since you are seeing these numbers actually. Has the rfrigerant ever been sampled before? Cross charge or oil content? just curious

TF
dont want to get too far away from your original issue, but is the machine in a carry over condition? Have you checked oil sump ressure vs evap pressure? when you say that the A/I board is good...

Does this outfit carry the blue vac micron gauge?

You should not have to supply your own vacuum pump. That should definately be a shop supplied tool. Don't get ahead of yourself yet with the tools. Reason i say this is that you wont be expected to...

I have seen this issue with a machine that was very low on charge. That would be pretty obvious to you if that was the case. Does there appear to be a good shell level in the evap glass?...

is this a micropanel or optiview?

Never thought about using a megger for a short like 2142 described, interesting thought, just wonder if it would be possible to smoke something in the LV circuit, are you talking about isolating just...

good tip
