?? why
if all its needs is a vfd then so be it.

You would also need a transformer.
So, yes you could.
The question remains why.
When you could get a unit locally that would be compatible with supply voltage and frequency instead of importing one that isn't and need extra external kit (and) cost to make it work. As I said, it makes no sense.

OK, it looks as though there are some EU based mfrs of AC units that use an inverter technology, and carry an input voltage RANGE of 90-260V.

That doesn't mean you MUST give it 260V, that means it will not DIE if it gets 260V during a surge. I also found that there are a number of power "Stabilizers" sold for use with A/C units in mind, all of which again, have a RANGE of up to 260V, with a stable output of 230V. So bottom line, this is likely someone not knowing what they are reading...

I agree.

My customer bought a 260 volt heat/AC window unit from Europe and says he cannot return it.

Independent of voltage issues (I've seen the suggestion that in MIGHT be operable over the 90-260 range), does it have UL or comparable approvals to allow its use where he is?

UL approval required for whichl products?

I was going to suggest that if it had solid state drive that it very well can run on 50 or 60 Hz and that 260 might be the upper end of allowable input voltage. Most high efficiency units anymore don't care if input is 50 or 60 Hz as front end of drive is going to rectify it regardless.

Of course it would have been the OP's customer's call to import something that doesn't match local voltage or frequency.
Maybe he was moving back from Europe and thought he would bring it with him?
There are more questions than answers......in the words of that song.

I agree that there is not enough information to give any sort of assistance.

What's needed is the manufacturer's name and a model number of the unit.

If it will work on 240V and 60~ then all that needed is a 240V circuit of the correct size and probably change out the appliance cord. If it takes more than that it's probably not worth the effort or cost.

Yes, if. And, even if it does and can, it still makes no sense to import it.

Unless it was donated and shipped by the the body/company making the donation, cost has already been incurred. I feel somehow, we don't have the whole story or maybe even, not very much of it.

Anyway, the OP has been given possible solutions to a problem that should not have existed. IMO.

People make a lot of poor choices when shopping by price on the internet now. This sort of thing used to take place only when people were moving from or to a foreign country. Now they see a bargain on a website and jump on it without understanding the consequences. I have friends that have done it, then come crying to me for a solution to how they are going to power their new Chinese vacuum cleaner or Norwegian humidifier. When I tell them the truth and they figure out it was no bargain, they sell it on Craigslist or eBay and pass the problem on to the next ignoramus.

That is what you get with what many call "mini split" systems these days. They often are marked 50/60 Hz. I don't know if what is being imported is the same thing sold elsewhere in the world, they may have North American market models but they are definitely not designed specifically for North American wiring methods.

You could well be right. If so, my advice to the OP to decline to get involved might be his best course of action/inaction.

In Japan the voltage is 90V, so voltage range 90-260V and frequency 50/60Hz design for a reason : the product for international market.

But here we are discussing sourced from Europe for whatever reason.
Off topic, but I think Japan is 100V.

I think I am on topic and my point is OP may very well hook up the air conditioner for his customer subject to the approval of local AHJ.

We don't know enough about it to offer irresponsible suggestions.
My advice was to walk away.
 
Besoeker said:
Totally disagree. If the kit is unfit for purpose, and that's what's coming across, the responsible thing to do would to advise the customer accordingly.

Whether the thing is unfit for the purpose or not is to be decided by the AHJ.
