Thank you. The pictures were some help but none show the inside. When you strip the inside for cleaning, there is no guidance for re-assembly. Which way do the plates set? How does the pump set? Which side does the air hose travel? This failed just before I was traveling out of town and put me in a panic. I ended up using an old skimmer that sounds like a trashing machine. The tank is in our bedroom and my wife was not happy with the racket at night. When I returned home, everything survived. I spent two hours assembling and disassembling the skimmer until I found the correct combination. I tried to take pictures for next time. I was very frustrated that Tunze did not have adequate directions or a video for this model.
