You may see that comment as support or an argument in your favor. But. What I see (as well as everyone else) in that comment is someone purchased a product from you, and the product they received needed repairing before doing what the product was designed and advertised to do. Albeit a simple fix, but that’s not always the case. In fact, it’s rarely the case from I’ve read.

Actually, in my case it was just a wiring mix-up. Luckily nothing was actually wrong with the product and it was how I implemented it into my lab that was the issue. Despite my reservations for the black duct tape around all the internals under the hood which seemed to be loosing its adhesion I still got a product that works as it is expected to.

That’s the tricky part about 3 phase wiring… if two of the leads are wired different, the compressors will run awkward and backwards… NOT GOOD! Thankful to have electrical engineers in my family. Make sure to read the wiring perfect and to do all steps during running wiring. It can save you some time and money.

Thats absolutely correct, and the only way to know is give the unit power and see which way the motors turn.
If they are backwards switch two of the 3 phase leads and voila direction reversed.
This doesnt sound like a mistake from Lanphan but really a electricians issue, whoever hooked the 3 phase power up to this unit should have been looking for the direction the motor was spinning and adjusted it according to its response.
The person hooking up the unti most likely wasn’t an electrician and did not have a lot of knowledge about 3 phase power.

You got that right.
What it appears you were talking about from an electricians standpoint is 3-phase motors specifically (often big, hunky, >15h.p.) and in this case it’s a chiller unit which is made up of (sealed) motors within the compressor units. BeeTeeDubahyew, I opened up the panels to see whats in side both top and bottom sections and there was no means of working out your suggestion. It does not quite apply in this case.
For instance, how do you see…
… when the unit is comprised of multiple motors (compressors) which are sealed. What, are you gonna look at the direction of the fan spinning? Which, oh wait, won’t spin because of the error state preventing the cooling system from starting up. So, nothing spins and you are suggesting to look for direction of spin in order to fix the problem. Hmm. I guess that you have not personally used, serviced nor installed one of these 3-PH chiller units.
A classic case of looking over the shoulder and giving directions when you don’t know (with first hand experience) the particulars of the situation invloved? Like telling your dentist how they should be sanitizing their tools with javex to lower their overhead costs…
In reality (and my case in particular) all that had to be done was to make sure that there was transfer fluid loaded into the resevoir and then swap positions of two wires at the breaker panel. All done in under 5 minutes. No problem. Wow. So much hassle. Oh my. Very big effort. Alert the press! XXXX dollars wasted!!!
Ahem, sillyness aside, if you would please read the whole thread you may realize the issues presented were already solved and the input you provided here was not entirely pragmatic. That said, I may be a bit harsh but I sincerely hope this rubs off on you in a positive manner… as they say “correct a fool and he will hate you. correct a wise person and he will thank you for it.” I wish to see this forum and it’s members elevated in their thinking, even if I gotta break a little skin here and there. <3
I totally understand your reply, and I also understand that you have solved the problem, but you are missing my entire point which is to help other people that may read this thread. Like you said to help the community get elevated. I wasnt even replying to your post, I was replying to @Boomtownpharms
I’m not sure why you are being hostile towards me. I simply used an example of how to know two of your leads need switched. Now if I couldn’t see a motor spin or didnt know which way they were supposed to spin and the first thing I did was get an error code I would switch two of the leads to see if it fixed it. if you had an electrician wire this they would have known to do this right away and you wouldn’t have had any down time waiting for china to give their “support”
FYI 3 phase motors are not all big >15hp motors, I have seven 3 phase motors here and they are all 1/2-1hp. 3 phase doesnt mean its always a large motor, however if you want a high hp motor it will most likely require 3 phase power.
I have also serviced all sorts of equipment from construction, industrial, and automotive, I’m far from just spit balling ideas over my shoulder, I’m speaking from year of experience in many different fields and if you didnt take such offense to my reply you could actually use your own advice and learn a thing or two.
Remember, you are the one that needed to reach out to china for help, I’m just the guy that spit balled over my shoulder with a solution that would have solved your problem.
Good talk though…

So now that you fixed the unit. If it burns the lab down, is it your fault or will you point at @Terry_Manager?

So you expected it not to work and you would have to repair it before you could use it?
Let your boss know that I have tons of equipment at a great price point. It will not work as advertised but he can have a minion fix it. Then if it does burn down the lab he can fire the minion. 
This new company is going to be a hit fellas.

You know I got you. I’m sure you have some equipment laying around that fits the description. I already called Hayfork, I mean the factory to see what is on the floor and ready to ship.
I can contribute a few sku’s to the catalogue, of all variations of “quality” and reliance

Funny. Cause this thread is for specifically the DLSB chiller series which does not seem to have any motor that spins when the wires are mixed up. Ergo, your “help” is still kinda moot. Thanks for the spit.
It would help if you had been speaking about the issue from the perspective of a user of a DLSB chiller, not a user of any random 3-phase motor.
Don’t worry though, I still love ya!
I’ve been trolling terry on ig. Commenting how he’s a scammer under his advertisements

so you don’t grok 3-phase do you…
there are three wires, they’re all hot, and wiggling at 60hz. they are 120 degrees out of phase with each other. the order matters, and isn’t trivially discerned (without just plugging shit in and seeing if it works). it is common to have to swap two phases to get things to go in the right direction.

Can the chillers be kept outdoors if covered and protected from the elements?
They can’t safely be kept indoors either so thats kind of a loaded question

They’ll work in-line with -80 ethanol?
Better than in the lab though! They could use it as a selling point!
“Our chillers are designed for outdoor use only, so when they explode they dont take the lab with it!”

For a little while yeah, but it will eventually take a shit and it can’t really apply much if any pressure so if there is any back pressure it needs to resist the flow ends up going to zero. All in all, you’re better off getting something properly rated.
