Here is some instructional tidbits to installing your above ground pool kit cleaner. This should better help to you with any pool cleaning needs.
“The safest way to cut the holes needed for the skimmer box and return line is to build the pool entirely and start filling it. Allow the pool to fill about half way up in order to set the liner in place(the weight of the water pushes the liner to the wall and in its permanent placement). At this point your pool is completely finished except for cutting the holes for and installing the skimmer and return.
Put on some shorts and get in the pool. Meet your helper(did I mention you need a helper) at the precut metal wall openings. Your helper is outside the pool facing the openings. First take the return fitting apart. There are just two peices to the return. Press the return (with the threads facing out) firmly against the precut wall hole from the inside. Doing this will push the uncut liner slightly though the hole making it easier for your helper to cut the outline. Continue to apply pressure with the return as the helper cuts the circle. When he is finished cutting, push the return completely through so your helper can screw the plastic nut onto the threading. Tighten firmly and its done.
Now for the skimmer. The skimmer also comes in two peices- a face plate and the box. The face-plate afixes to the wall on the inside while the box hangs on the outside of the pool. The skimmer connects thru the wall using several screws and your pool’s wall is precut for them. Line up the skimmer plate against the precut wall opening on the inside of the pool just like you did with the return. Now, take one of the screws and poke it through the plate, liner, and wall hole. Have your helper line up the skimmer box on the outside of the pool and fasten the screw you poked through to the skimmer box. Repeat this until all of the screws are in place and tighten. Your skimmer is now in place and the only thing left to do is cut the liner around the inside of the skimmer plate to make an opening.
This process is harder to explain than it is to actually do. Just remember- when in doubt- cut small.”
