Zep solve, modern day virginia 10. Nothing enviromentally friendly about it though. Use chisels and wire wheel, zep solve for final degreasing.

How bout an "off the shelf" chiller, coupled to a good size storage tank and use a mixing valve to keep secondary loop at desired temp?

I concur. How are you checking branch pressure from t-stats. If you are relying on system gauges you probably have a bad gauge. 20# on main and lowest input is duplicated on branch. If you have 0 at...

A shot of the orange kool-aid would take care of that foul taste!:D

OR
Good, Fast, Cheap.
Pick any two.

Just sub out the insulation, It is the most important from customer perception, a good insulator will make your job look great. Contact carrier for controls, keep it all consistent with a single...

I agree
#1 energy user in a office building- The chiller
#1 reason a particular chiller is purchased-operating cost
Trane spends major $$$ on design improvements just for 1% increase in efficiency...

So did mine, until last night. I took them back and am trying to find an apartment as we speak. Feels good to finally have them back, can't wait to use them again!:D

No rise in microns means no leaks. rise in microns means leaks or moisture. If it rises and stops around 1000-1500, you have moisture and it quit boiling(Iforget the boiling point of water at 70* but...

I remember years ago carrier had some problem with
green slime on some small splits with scrolls. Turns out they werte leaking on low side and pulling into a vacuum, thus sucking in air and...

Hey Ibend,
I would have thought you would use 1/4 copper to pull a proper vacuum, seeing hows your such a stickler for doing it right. Also,if you pull down as low as you say, and check for micron...

Yeah, yeah...I know, thats not the proper way, but first, what are you working on that requires the kind of accuracy you are talking about? I assume you are talking about using a known refri. at a...

Personally, I have avoided them. I am kind of rough on my gauges and don't trust the durability of the digital. I don't like meters/tools I can't trust. 30 seconds and a pocket screw driver and they...

Every highoil temp alrm on RTAA I have seen is due to dirty coils or bad cond. fans. these machines trip on oil temp before high head. Have had sevral calls where everybody swears the coils are ...

No Gloves! Definate safety violation. That stunt would get you a free trip to the dr. and a drug test (not in that order) where I work. Not to mention the following investigation and report sent to...

These machines like colder tower water to maximize afd efficiency. Try a floating tower water set point that equals 5* above the oa enthalpy. this will give you the coldest water possible without...

Ive only heard of this happening on Trane RTAC's. Something to do with the falling film evap. I dont totally buy the refrigerant migration theory the factory gives.:eek:

May be wired to independant duct detector. It may recieve power from your rtu, so when you power down, you reset the duct detector.

Kids today are afraid of hard work. I don't care anymore if I sound like my old man, he was right!:eek:
Sucks to be your kid though:D
Hell appreciate it though when he turns 40, and realizes you...

Of all the places to try and save a buck!
If you mark up prices, use the correct oil and make more money.
If you lose a compressor, will you tell the customer you "went cheap" on the oil.

Why would you want to pay an extra 28% for the electricity to run this fan. Dialing in the cfm's maximizes efficiency.
Would you run the chilled water 28% colder than the system was designed for?...

I think he means 28% over design(what the system/space requires). Actual delivery depends on installation specifics of the ductwork. This unit obviously has less ductwork than the unit is capable of...

And I was just thinking about sharing my secrets for checking an earthwise purge with you:cool:
I'm sure my thumb smells better than your nose:eek:

I could give you the rules of thumb I use, but my my thumb is probally bigger than yours!

If you can't figure out how to call trane for parts, how you gonna figure out how to fix the chiller. Sounds like some work for a chiller mech. in ashville coming up soon, bet it involves more then...

The acid core won't neutralize the acid on one pass, so even if you put it in the suction line, you will still get some acid to the comp. The acid ends up in the oil, quickest way to clean it up is...

Was just looking at a cut-a-way in the shop and it does have a dip tube. Think about it, what is the point of an oil drain if it won't drain oil.
I don't know why the old bristols didn't have a dip...

Thank god:D

By removing the heat and displacing it somewhere it is less objectionable:cool:

Inverted start. I was really surprised how long it took for the ref. to come back to evap. the first time I saw this.

Tank overfill switch? You mean people use those things!:D

adaptaview retrofit for ucp2 not available yet,end of the year they say......
adaptaview retrofit for ch530 available now, quick, easy and reasonable.

The Trane literature Ive seen says over ten megs. is acceptable, below 10 megs, you need to pull the chart and check using temp. corrections. Had a Rtaa read in the 30 range, old carrier tech refused...

Funny, I didn't know RTAA were available with PWS. Learn something new here all the time.

Gauges on in spring for a complete check-out. subsequent visits get good visual and temp check, no gauges unless something looks fishy.

This is a commercial unit,probally three phase. Clean the coils first, can't properly diagnose until you do. after you split the coils you will know for a fact tht whoever told you it doesn't matter...

Is the machine they are keeping cool important to them making money? I bet it is. the chiller they have is at or near the end of its life (or was but is now). sell them a new chiller and lock out the...

Fla. or Ireland is good. If you end up in the deep south(Fl is not deep) you'll have to start calling your kids by their middle name!

I only had problems from new construction, one dirt bag builder I fired after I had to start going to the closing attorney to make sure the checks were made at closing(gotta love small towns. My...

If you don't have the patience or skill to find a leak with a good electronic(tried and true h-10) all the gadgets in the world won't help. If you can't find a leak on low pressure because there is...

Unless their last name ends in a vowell, Then watch your back, and your horse

Seems to me that fighting each other would imply one heating while one cools....not good! However from your post it sounds like one unit does the left side and one does the right, or front and back....

Whamo-Tried and true technical term

Sounds like you asked the tech and he told you 16 hours{sounds reasonable} then you caved to the customer and bid 12 hours{BIG MISTAKE, next time stick to 16 and NOT TO EXCEED} good sales, business...

Thats a great question. I think I'll ask our safety mgr. how we should proceed. They tell us tie off points have to be rated for like 3000# horizontal pull. The lifting points on most units don't...

Is it safe or possible to install a wshp on my existing well used for domestic water? I think I saw this done about 20 years ago at a house. I am getting ready to replace my old lp furnace wiyh a...

Quick check for EXV: Cycle circuit off, watching the sight glass at exv, if you see any flow right at or just after shutdown, its leaking by.

This should get interesting!

Ive seen this type thing done before. its not perfect but will be an improvement over 100% O.A. with no cooling. Even if you don't get the supply below 60 you will still remove moisture, the coil...
