You will see others complaint here about that terrible owners manual and they are absolutely correct. However; Most of the information that you need is right here on the sale page so look it over as you begin because otherwise that manual is pretty much worthless that appears written by someone with not a great grasp of English.If you get the model with a glass jug then it’s tough putting the handle on with the metal straps. The video above shows a second of someone easily screwing the nut on the screw. Here’s what I figured. You don’t try to go with curve they are in. You reverse the curve so you are working above the connection, and not below. Why they have the curve the other way makes no sense. Also have a screwdriver and pliers handy. Trying to use your fingers only produces a lot of swearing….As for operation..MEN LISTEN UP: Yes! Those “Safety Read First” instructions are often full of obvious items, but I didn’t after wasting time setting up the handle and such, then I discovered why the first batch didn’t taste very good…Because it wasn’t supposed to. It’s still good for the humidifier though. ALSO: pay attention to Cleaning Instructions. I used an abrasive pad to scrub the bottom, but shouldn’t have. I didn’t see that earlier either.Otherwise the unit seem to work really well. I haven’t timed it but I think it fills the distilled pot in about two and a half hours. The fan is quite noisy, but I was expecting that…
