Are the VSD cooling coils micro channel?
You are in for a ride on that one. Check every fuse. Check input and output voltage isolation boards. What is the VSD model # on the side of the drive panel? Was the failure directly related to the...
You need Carrier lit number 020-332. Seriously doubt the economize damper would cause stacking in the condenser. I have seen those dampers where the linkage comes off though. It’s mainly to keep from...
Approach is another tool. Like any tool you need to use it properly. Design numbers for approach like 1 to 2 degrees are going to be seen at design conditions (full load/flow). Don’t expect a machine...
At this point I have to say oh it’s one of those jobs. Been there. Not the best of places to be in but hey it’s work all the same. Document everything. Remember, chillers ain’t rocket science. What...
If it’s a 2 pass it’s pretty easy to troubleshoot a pass divider leak without ever pulling a head. At least one that would cause enough trouble to worry about. Any good chiller tech should be capable...
Leaving water temp sensor or evap refrigerant temp sensor. Get some ice.
For that vintage machine you are going to need 160.78.... 84 is for the newer stuff. A lot of revisions and design changes have come about. You can chase your tail looking for things that don’t exist...
Not my fault but went to do a PM on a boiler at a Fire Hall. Another company was tearing out the boiler to replace it. Turns out THEY were at the wrong fire Hall! Free boiler and install.
Really boils down to the building/plant infrastructure. Medium voltage switchgear, associated cabling and equipment is not cheap. Installation, maintenance and operation is also not cheap. Over the...
I usually don't but others do if it's over 3 tons.
I agree with the safety and subbing out deal. We used to rig everything. I liked it because I knew it was safe and had control of the situation.
I think the JCI/Simplex Grinnell/Tyco deal was a good move. The fire protection and access control/security business is huge and will only continue to grow. Merge that with a building controls/Hvac...
JCI/York, sorry I bleed Caribbean Blue :grin2:
When high levels are encountered which is rare, I use a full face with organic vapor cartridges. Butyl gloves for oil or filter driers where possible skin exposure is present. Standard protocol these...
That post was from Feb 2016, it got revived. I've done my research on the CVHS since then��
Have you read any of the manuals for these machines? They are recommending a complete teardown and inspection every 5 years and every year if on industrial service.
Never used epoxy but have soldered up a few.
I can say I have been at it awhile. Not as long as some of the real old timers. Started out before high school riding my bike to work in the summer. Was lucky enough to work for a guy that had some...
The key to demanding higher wages and benefits is to specialize. Most folks can do commercial/residential/light industrial. But can they handle the higher tonnage stuff? Say 2000 tons plus, mag...
Thats pretty damn spot on there!
Way, way back, like in '93 or so we put in some of the multi indoor unit heat pump systems with a single condensing unit. Had to have special training, etc. Think the first one was a 4 indoor coil...
This one sounds like a software issue but then again, one has to ask how long has this been happening? You should really know where to find the software version of all the boards quite readily. A...
Curious as to how long this issue has been going on? Was it happening prior to the changing of parts? Or was it something that started after the change? There are a lot of things you could check and...
Ahh the joys of the facility/property management crew. Their sole job is to save $$$. The stories I could tell of one particular company that was "saving" $$$. They fixed things with jumpers and...
I have 2 sets of the 4 piece pick/hook tools. They are inconvenient to carry around in a tool bag. This tool is about 4" long and holds 5 gaskets, the pick comes out and packs up inside so no sharp...

Pretty much use Yellow Jacket exclusively. Just bought a new gasket tool the other day.
Probably need to update the firmware in the elinks. Also make sure they are properly grounded. Is this your only issue?
I got a nest for free and have not had any issues. No common wire either. ICP 90+ single stage gas with straight AC. It will kind of annoyingly set back or up on its own though.
Mercury manometer, then Ritchie/Yellowjacket. There is another type that I have some interest in, more environmentally friendly than Mercury. http://www.vacuator.com Haven't tried one yet but soon.
Maybe Frick could build you something like that... but still you're talking $$$$$. We have a York system that liquifies natural gas. Special compressor, special mixed gas refrigerant. Evaporator runs...
Not saying it cannot be done, BUT, to maintain those temps with someone going in and out every 10 minutes or so is going to be damn near impossible. There is also no way anyone even with an...
I tried some of my Dad's Redman wayyyy back when I was about 14 or so. He used it when he ran out of smokes. Remember feeling funny and looking in the mirror and was a greenish color. That was right...
Not a mistake by any means. Its a tool with a learning curve. Learn how to use it and it will serve you well. I have seen many folks who just cant seem to grasp how it works and fail, and blame the...
Will send you something soon.
YMC2 drive is actually called the Raptyr, Vyper is the TM 3 replacement. If you have a Vyper, drive the drive model # will start with VSD. If you have a Raptyr drive the drive model # will start with...
Fusible plugs are usually only designed to melt at a certain temp and blow. Basically a fire code issue where if the unit were to be in a fire it would relieve and not be a "bomb". They should hold...
Post a picture of the compressor screen at the highest load you can get on it.

What Jay said, check your pressure drop across condenser barrel. Just because something has worked for years doesn't always mean it was right. At the very least the machines should be tested for flow...
If Ya can't beat 'em, copy 'em!
I saw that on coolingpost too. Crazy times out there! Looks like a Trane s chiller. To think carrier threw the gauntlet down on low pressure way back! Who knows, maybe some of the other major players...
That type of damage, looks like something let go on the back end of the shaft. What did the thrust bearing look like? There are only 3 little bolts holding that, maybe came loose? History would show...
Imagine that...
I get this a lot, where folks cannot seem to find something on quicklit but when I search it pops right up.
It's interesting, I had an airline fitting today that uses this technology, leaking its ass off. I cut the tube off clean and re inserted in and voila, no leak. 170-180psi air with the most slippery...
Sporlan/Parker did a show and tell at a local distributor last week. I am still skeptical from a service standpoint but they seem to have it nailed down pretty good. The rep said that the seal comes...
That line is there to drain any residual refrigerant that winds up in the cavity between the condenser baffle plate and sub cooler box. Usually there will also be a vertical welded pipe that runs...
