What is the little black knob-like thing for? It was loose in the box with the little blue elbow thing and the instructions don't mention it at all.

little blue elbow you hook up to the top of the filter for the extra oxygen it can draw from the black knob with the air tube for controlling how much air can generate through venturi effect. Very good filter for controlling algae or hospitalize a 10 gallon tank for most of the fish parasites infestation.

Not sure what you mean. There are instructions in the box, but if you are not handy, you should hire a plumber.

Mine came with a T-knob. It seems the picture has changed since I ordered them. That knob almost looks non-functional the way it is now.

There is suppose to be a handle ty-wrapped to one of the steel legs and there should be two black handle ends in the box also. If worse comes to worse you could use a piece of 1/2 pipe and drill a hole through the middle of it then bolt is where the pin goes. it works but the handle moves around so make sure you are wearing gloves so you dont slip and pinch your hands.

Assuming it's turned on(far left/mute button),The solid up arrow with a bar under it should make it open or close completely. The side by side up or down arrows are for opening or closing any amount you choose. I've forgotten for sure, but it seems like I remember a screw (with a label that says"remove this screw) that held the cd carriage locked for shipping. Maybe it won't let it open the lock screw is still in (if there was one). Anything beyond that, I'd say it's defective.

There is a key in the box it is black plastic with 2 tabs on it put it into the holes on the back of the unit and turn till it opens. You may need to pry it with your fingernail.

I have a swivel circle at the end of the handle, too and I can't figure it out. I've tried to remove it thinking it was there to hold the tag but I can't get it off!

Sorry I sent it as a gift. I think you could probably google instructions. Good luck :)

I didn't get an instruction manual with mine either. I googled for it! Good luck!

I received no instructions either. I think I got it together but it is not much. I should have waited and purchased a better one.

I just looked at mine. I noticed that I also had something rattling around inside. Sounded like a small piece of plastic. I saw no easy way to open. It doesn't affect the operation. I'm going to leave it and not worry about it. It's probably just something loose from the manufacturing process.

Provide Name, did you ever get yours working? I can't get either the long knob or the short knob to "click" onto the outside. There's a small kind of "facing cover" that's in the way, and the short knob won't fit either side.

I have never used mine. It's still in the "box" if you can call it that. Sorry I can't be more help.

There should be a hex wrench with the doorknob, if not it is a standard size. You use it to loosend the handle and either rotate it 180 degrees or switch sides depending on your knob.

None. As I remember, you take it out of the box, line it up with your doorknob, unlock the handle on the BB, slide it up to the knob and then lock the handle. (Please read the instructions for full information!) There is one caution I heard from a Locksmith, and that is you have to be careful not to put too much pressure on the doorknob or over time you could bend it and possibly break it. Works great for me, just what I needed!

There should be a small screw on the knob, its tiny, use an eye glass flat head.
