If you are having trouble with those goofy paper instructions, go to their site here: http://www.r-com.co.kr/ and look to the far right, little green box and click on Resource Room I, II and III. There's little videos there that are very helpful in assembly. Also I fixing to do my second hatch and notice I couldn't get the humidity up. So I took apart the top of the bator and notice there was a split where the tubing connects to the tit inside was split so I cut that very end off and reattached it. So still was not pumping water, so I took apart the pumping station and notice another little split over the little wheel. I cut the same length from the end of the tubing that goes into the water jug, since that side is longer. So apparently those parts of the tubing wears out quick after the first hatch. It is working now like a charm. I'm going to the fish store tomorrow to see if I can fine more tubing for future use. I hope this will help everyone out. Also there was someone on this site that was requesting a picture of the pump assembled. I hope this also helps. Good Luck!
