What happened to the one year warranty
I ordered a concentrator received it fast leave it fast took another Box install it read the instructions got it up and running within 30 minutes it got extremely hot and quit and quit code 35. Contact them through email they want me to take a video off all kinds of goopy stuff ask me if I read the instructions that I've been fine a lot that I all I want to do is exchange it for a working unit you should provide me with they could not provide me with that and the final email we can't find anything wrong with your unit go ahead and use it. Don't do business with this company their telephone number nobody answers no voicemail Also it takes forever to reach somebody on email and they don't provide you with their name
