      Rated 4 out of 5 by from Pretty pleased I installed this liner this past weekend. All in all- as far as liners go- it was not too difficult. As with all liners you must assure that the seam between the floor and the wall is evenly positioned around the entire circumfrence on the pool, not only to maintain the intergrity of the liner- but to make sure your pattern on the wall is symmetrical all the way around the pool top. Follow instructions carefully and you will be very pleased with the finished product. I recommend once you get the liner opened in the pool bottom- to fold the walls inward so that you can see the floor seam- then with a few people in the pool- guide the seam evenly around the floor / wall junction until it is as centered as possible. The begin working the walls of the liner up and set them into place temporarly - you will need to continue to adjust as the water level increases. Do not begin filling the pool until you have removed as many creases from the floor as possible- then once you begin to fill- stay in the pool so that you can continue to work out little creases here and there- i used a broom for this part- once you get to 1 inch or so of water - you are pretty much stuck- it is worth it to take your time on this step especially. Start in the center of the pool and work your way out and around. As the water level works its way up the pool- continue to work the walls to elimiate bubble and creases. Good Luck!

      Installation Instructions
      RECOMMENDED ITEMS NEEDED FOR INSTALLTION
      • 2” gray duct tape with non-asphalted adhesive
      • screwdriver
      • garden hose
      • sharp nail or ice pick
      • industrial vacuum or household vacuum (filter bag removed)
      • tamping tool
      • masking tape
      • utility knife







        WARNING: Liner should be stored at room temperature for at least 72 hours prior to installation.

      PREPARATION OF POOL BOTTOM

      1. Spread a 2” layer of brick sand over the entire pool foundation area inside the base rails. Use a rake to make the brick sand flat and smooth. Tamp sand to help reduce footprints. In place of brick sand, you can use “Soft Step” Floor Padding. Cut the sheets to fit and join them with duct tape along the whole length of each seam.

      2. With the brick sand, make a curved cove about 4” high and 4” wide all around the bottom of the pool wall on the inside. Pack firmly into shape. Pool Cove can also be used.


      LINER INSTALLATION

      1. Place the closed liner carton in the center of the pool.

      2. Open the carton. Do NOT use anything sharp to open the carton.

      3. Unfold the liner and spread it out in the sun to warm up.

      4. Inspect all seams and surfaces for holes.

      5. Spread out liner. The curved seam should be centered on the cove at the base of the wall. The other seams will form straight lines across the bottom of the pool. If seams appear to have flaps, check to see if correct side is up.

      6. Smooth out all wrinkles in the bottom.

      7. If you have a beaded liner, fasten the liner in place by lifting the sides of the liner and inserting the beaded edge into the liner retainer on the top edge. If you do not have a beaded liner, lift the sides of the liner and drape them over the top of the pool wall. Fasten liner to the top of the wall with plastic coping. Let the liner hang slack for now. Do NOT pull liner tight.

      8. Start filling the pool with water. As the pool fills, work out the wrinkles and smooth the liner to the wall. Remove the plastic coping around the top edge of the wall one piece at a time and adjust the liner. Keep smoothing out the wrinkles.

      9. Do not install faceplates, inlets, light fixtures, etc. until water reaches 3” below each opening. Premature installation might result in the liner tearing away from the opening due to stretching as the water level increases.

      10. Proceed filling pool until water reaches desired level.


      OPTIONAL STEP TO ELIMINATE WRINKLES

      1. To remove air from behind the liner, which prevents wrinkles, insert a vacuum cleaner hose through the skimmer hole in the pool wall behind the liner. To minimize vacuum loss, seal the opening around the hose and the water inlet using cardboard and masking tape.

      2. Turn vacuum cleaner on. While vacuum is running, you should be adjusting the liner with short tugs to eliminate wrinkles. If you have trouble shifting the liner into position, shut vacuum off for a few minutes. You should then be able to adjust the troubled area before continuing with the vacuum.

      3. Start filling the pool with water. The vacuum cleaner should continue to run until water level nears the top. Make sure to keep vacuum cleaner hose above the water level at all times.
