This part of the general guide on Installing an AG Oval Pool shows you how to install the Bottom Rail and its connecting structure. This process includes connecting and leveling the Curved Side Bottom Rails and Plates, submerging the Straight Side Upright Channels, leveling and squaring the Straight Side Uprights and installing the Pressure Plates. We suggest that you review the previous parts of this series before reading this section. Also, these instructions may vary according to your pool model so consult your owner's manual for any variations.
SORT OUT BOTTOM RAILS - Separate the Bottom Rails from the hardware packages. There are three different lenghts. They are color coded by length. The orange tagged Corner Bottom Rails provide the transition pieces between the Straight Side Bottom Rails, and the Curved Side Bottom rails. The Straight Side Bottom Rails are used between the Straight Side Upright Assemblies. The Curved Side Bottom Rails are the longest and are used on the ends of the pool. If your pool has resin bottom rails, make sure you use those and not the steel stabilizer rails which are used on the top of the pool.
CHECK SQUARE - Measure the distance from the end Upright on one end to the end Upright diagonally across from the first Upright. Then measure the distance between the two Uprights on the other diagonal. If they are not the same, the Uprights as laid out are not square. Shift one side of Uprights left or right until the diagonal measurements are the same.
GO TO NEXT PART - At this point you have all the the base structure assembled and are almost ready to erect the Wall. But first you must prepare the initial sand base inside the pool. For the next set of instructions on installing an Above Ground Oval Pool, go to "PART 4 - PREPARING BASE". To return to the Overview, go to "How To Assemble an Above Ground Oval Pool - Overview".
