How long have you worked for your current employer? Are you self motivated? or do you have to be told what and how to do something? Or is it just a stingy ass boss?

How long have you worked for your current employer? Are you self motivated? or do you have to be told what and how to do something? Or is it just a stingy ass boss?
From what I heard, you work 12 hr shifts and after I did the math of the total amount made in a year it actually breaks down to about $18/hr. Hell I could take a cut in pay, stay here and not get my...
Gas valve pressure regulator may need to be backed off. I had one like that a few weeks ago.
York compressors are not known for manual unloaders. As I have stated before, you can get low pressure switches that close on pressure fall to energize (unload compressor). As previously stated, you...
ADDISON and FREONRICK are on the right track.
I forgot to mention in my last post that you can get adjustable low pressure switches that close on pressure on drop therefore energizing the unloader solenoids and unloading the compressor and it...
The unloaders should be set to unload on suction pressure drop (at 58) with a 12# differential (loads at 70 and above for mechanical unloaders). Or set to unload on air temperature drop to...
Is the machine designed to shut off on pumpdown? If it is, what is the low pressure switch set at? Set it at about 25 psi. If your compressor does not shut off on pumpdown when the liquid solenoids...
Have guns and tools will travel!!!
By Biblical proportions I meant that the people have been exposed to all kinds of toxic waste, dead people, etc. Then you take all of these people who may be infected and spread them all around the...
I live by the racetrack in Vinton, but work in Texas. I only went by what was reported by the newscast. So if that was a false report I heard, then that is a good thing.
They need to mount M60 machine guns on the rescue helicopters, that would put and end to them shooting at the copters.
I listen to 103.7 FM out of Houston and Jim Pruett's Guns and Ammo was running special prices on "Looter Shooters" (pistol grip Mossberg pump shotguns) and ammo. My home is well armed and if I were...
Superdome or Astrodome? Superdome has holes in the roof, would be impossible to control humidity there. I guess it could be possible to have clouds form given the right atmospheric conditions.
Need more info, suction, discharge, superheat, subcooling, evaporator delta T. Is the evaporator clean? Blower wheels clean? Blower belts good? When you energize the unloader solenoids you are...
Big oil companies should donate some of their profits to the relief effort if they are not going drop the price of fuel. Man, that is some good crack I'm smokin'.
Hurricane evacuees are landing in all points between N.O and Houston. Here in the Lake Charles Louisiana area, the civic center and hotels are all full and of course some of the criminal element got...
Put actual guages on the machine, do not rely on the display. With the machine not running (toggle switches off), see if the display pressure readings match what your guages are reading. This will...
Ditto, if you are reliable and productive, don't worry about it.
Does your system have a suction line accumulator? No txv rules out large tonnage pot compressor with solenoid activated unloaders. Need more ifo.
I have worked on Carlyle 5H40, 5H80, 5F20 series.
I had a York Millenium Recipak chiller do the same thing I would get a Motor Current fault on various occasions, one being a high head pressure problem, and on another occasion had oil pressure...
How many circuits does this chiller have? How about capacity control? Possible that there may be a problem with another circuit's txv affecting the one you are discussing here.
Sounds like a bad txv power head to me. Then you will have to remove all the excess oil as it returns to the compressor.
Are there any records of the running pressures, amps, oil pressure, voltage, crankcase/head temperatures, etc. on the original (7 year old compressor) or this 18 month old compressor? You mentioned...
I assume that you did not work for any a/c company while attending school. I am sorry to say there is not much you can put on it except that you are a graduate of said school and list everything...
The people keel over shortly after retirement, bodies no longer used to fresh clean air. Will probably happen to me too.
Attach one meter lead with alligator clip to the common side of the transformer and test to the rest of that circuit starting at the y2 terminal and follow that circuit from there to the contactor...
Keep ears open, eyes peeled ask questions and ask to troubleshoot and repair anything you think you may be able to handle without getting in over your head (with supervision of course). This shows...
I too work in a paper mill (one of our accounts) we are forever chasing the same problems as you. The problem is with the water circuits for the condensers, they have crappy water and corrosion...
Any oil in the crankcase sightglass? Was this a rebuilt compressor or new compressor. If you did not run it that long, valve in the compressor, drain the oil and put fresh oil in (4gs oil/300...
I assume that you only have problems with one room and not all of them. What kind of controls are they? Electronic or pneumatic (air pressure) thermostats? If you have pneumatic stats it is possible...
This is true, markwolf. Check the airflow pattern coming out of the condenser fan grill. If the airflow is more out of the sides rather than straight up, your "clean coils" are not that clean. But...
Are the unloaders set correctly? Are they loading and unloading rapidly? Are all of the condenser fans running/cycling correctly? What kind of temperatures are the compressor heads (temp taken at the...
Have used T bars, cranes, come a longs and chainfalls. Will have to remember a tow truck, damn good idea!
Just remember to do a good start up on that compressor and find out what killed it to...
Unhook the lightstat control wires from the circuit board and install jumpers between R,Y1 and G. Or check with your meter across R and Y assuming you have control voltage.
I have attempted to...
Regulate outlet water, aim for 10 deg. delta T. You may have scale build up or low water flow. Is the condenser one of those coil types or barrel type? Coil type you will have to use descaler with an...
Have seen this before implemented on 80 ton rooftop Mquay units. Casino owners did not want the units to be visible from the road so there were cosmetic additions to block the units from view....
Got to love those "modified" units. Sounds like to me that it is an older machine. Ain't nothin' to rewire correctly, I have done it numerous times with excellent results and running better than the...
Need a little more info, all the basics please: suction, head, superheat, subcooling, supply and return air temps, etc.
To make a SWAG (Sophisticated Wild Ass Guess) I would think you would need...
Obviously these are tandem compressors, do they both run at the same time all the time or do they stage up and down? If there is a selector switch to run either compressor as lead and the other as...
Both circuits shut off at the same time or does the #1 compressor pump down like normal and the #2 just shut off? When it shuts off, are the liquid line solenoids still energized? If they are, then...
Regarding your 10 ton unit, check to see if your coil is split with 2 txv's, make sure the bulbs are insulated, check the belts and pulleys, return air for correct size, delta T across coil,...
I should have asked what is the current chilled water setpoint and the required set point? and how are you controlling it, supply or return? Return is preferred. Your head pressure is low on both...
Need more info, need actual pressures on guages, suction line temps, liquid line temps, superheat and subcooling readings. Do the compressors have capacity control? Air cooled or water cooled...
Richper, Did you have a compressor failure? If so, was it mechanical or shorted or both? There are other solutions to your capacity control dilemma that can be put in place. When the compressor...
I do tend to take my job seriously and any assistance I can offer to make someone else's job easier, and to not have a callback, I will.
Y'all still mad at me for that post I made in the America,...
Fat Eddy and Bobby M, The extra measures that I take to troubleshoot and repair a system gives me a rough idea of the compressor life left (if any due to unit condition) and that information gets to...
JRC2905, If there is a 1/4" fitting anywhere on the compressor that you can put a schrader tee on for access to the compressor. There may be a low or high pressure switch hooked to the compressor...
Fat Eddy and Chiller Mekanik, re-read the post, it is self explanatory.
