I was there 20 something years ago, I moved on, but I remember a little turmoil with a manager back then too. Jim, not sure if you are the highland variety of Jim that was there in early 90's. If you...

I am now.

York 56, would you have the autorun file/setup.exe for IcE1.04. I have the software backed up to cd from an old laptop that crashed. But the trainer carefully removed the setup file so this could not...

I'm having a problem in chiller open forum. No matter how many times I log in, my user name is not in top right corner. But I can come out to Pro forum and be logged in. So I think there is a problem...

I'm having same issue trying to click on a file in a thread and it keeps telling me log in, I do , and a1 second box welcoming me pops up but cant get in. also my user name not coming up in top right...

Let me guess. you have a centralized pumping setup and no Auto- Isolating valves at the chillers, so you are mixing water thru 3 chillers and need all 3 to be on to have control of the temp??

ah ha! call an electrician. (pro).
Somebody forgot to tell the installing electrician that it is XL start, and the 500 feet run of cable needs to be sized for that inrush (with no voltage drop)???...

You can plug 10% of any pass. You are more than likely a two pass evap so 22 tubes. All the burst ones are at the bottom. Somebody froze that up on a transfer!! Oops.
If I were you I would recommend...

I'm no expert on YT's, but thinking along the lines of a YK. Are you sure that press. trans. on the evap is reading correct. Not sure if the YT uses a evap Refer Thermistor like the YK, but I have...

Thanks 56 and NC. That explains that

I,m going off of memory here, but i thought the SI says hold the min. button and Optiview should read 0% not < 0%. Hold the Max. button and Optiview should read 100% and NOT > 100%.?
On the style E...

On the liquid level sensor with 4 buttons, what is the setting for min. and max voltage. The SI187?? doesnt say the min/ max. The older style uses .37 and 4.13vdc. Is it the same on these?

I think kw/ton and COP are two ways of describing the same thing only inverse of each other. kw/ton is" motor kw divided by tonnes of refrigeration."
Where as COP is" kw refrigeration divided by...

you need to watch conditions (operation button I think) enter thru each step of coditions, watching pump down timers and load/ unload timers. It wont start second comp until 3rd stage of loading. if...

1.5" will give you 5.4FPS
1.75"??? 4 FPS
2" will give you 3 FPS
Hope that helps

56, just curious if that 9-15" changes on size of chiller? TIA

oouch!! that bang would have hurt ones pride.

Is that 10 psi being measured near the 1" regulator or back on the 2.5" ?? I would get it away from that hi velocity area and make sure there is a pigtail on the gauge. Just a thought.
Ga1279 is...

I have seen the F2 fuse on the 1730 board be just loose enough to be vibrating in and out of connection.
Its located at the top right hand corner of the 1730 board, make sure it is seated and not...

Update your CP Aust, with email address. I might find something for you.

I have seen it 2-3 times in last few months . Moisture getting inside the plastic top of the sensor where the flat cable terminates at the sensor. You can see the green corrosion under the clear...

I agree with turbo and York56. But I would get the zero calibrate done, then disable refer lev. control and run it up, see how it behaves with surging. If OK try to cal the span at 80% setpoint and...

whats it display when it drops out? NO RUN PERM

I have one ordered, and hope it is self explanatory. thanks klove

I found it in RP for the unit. Thanks bullgear
any thing I need to know about using it. Is there a check valve in the spindle valve to avoid sucking air into the machine?
TIA

any chance you have a part num. on it

Anyone ever seen a solution sample valve like this on a YIA.
Allthe sample points are the same. Is their a trick to it , or are they plugs like they look and if so whats the best way to get a sample

Multiply tonnes by 12 to get BTU's in Thousands. Divide the answer by 3.415 to get watts by the thousand or KW. Their is 3.415 BTU in a Watt

refer, conversion is Kw x 3.415/12= tonnes. Thanks Scewit

Scewit, its the 080 compressor. Do you have the teardown manual on it?

Anyone know how to get their hands on a Teardown Manual for a CVGE. Its European high speed /hi press(R134a) centrifugal? Any help appreciated.

Thanks for the replies, I will look into the pdf creator software. any recommendation ?
Not all the manufactures are making IOM available for download anymore.
I lost a HD on laptop that had5...

Glad to see the chiller forum up and running. I am wondering if anyone has a good way to copy IOM's to pdf files. The reason I ask is I have a lot of manuals in the van and am getting worried about ...

500 is a constant for water. The reason I believe is, you are dealing in GPM(minutes) and BTU/HR (hours)
60 Min. in an hour and the weight of 1 US gallon of water 8.31 lbs.
60 x 8.31 = 498.6...

that formula is for chiller COP. If you are doing total plant COP, then you need alll pumps and tower fans. Tower fans are cycling so you would need a KWmeter to measure that. BUT CHILLER cop will...

KW refrigeration div by KW electric input to motor.
You need a Kw meter really. Electric KW= KVA x Pf (power factor)

My mistake, try it again.

R404, not saying i am an expert on the YT, but it sounds very similar control to the YK. I would double check your refer level sensor calibration, you may be stacking it higher than you think. If...

thanks, CHMAN, would appreciate anything on this machine. have the pic 2 IOM. Never thought about the heater. alot of other issues, running HP because of low flow, tower fan gone bad, designed around...

Ph-D I could use one too. Also looking for a renewal parts form on these. I have a 19xr frame 3 with pic2, low Dis. SH at times, i am thinking the linear float is sticking. Waitng for price and...

The formula for KW of refrigeration is L/s x Delta T(*C) x 4.19kj/kg (for Water)
To convert GPM to L/s GPM (div by) 60= GPS
GPS x 3.785= L/s
60 seconds in a...

Thanks for that york56, some how the email notification for response to this thread went to spam folder.

No micro-gateway or e-link. If you check the sales order the number of tubes does not match the renewal parts number of tubes on the style E &F, and i would say the same for G. Trying to calc min...

I am looking for info on style G. I see the main board has changed from style E. I have a start up on one in a few weeks so I need the IOM on the controls. Also looking for the Renewal Parts on it to...
