 How-To Worksheets Installing an Above Ground Overlap Pool Liner Cove
EARTH COVE: Use screened damp earth to form a cove around the inside base of pool wall. Shape and compact firmly. PRE-FORMED: Specifically designed pre-formed pool cove is available from Pool World. Follow cove manufacturer's instructions. Recheck pool for roundness after installation. Liner Seam Positioning

Be sure the liner is evenly distributed over the rail without any bunching or pleating. If any occurs, correct as you are adjusting the liner tension. To correct, grasp the liner wall nearest the wrinkled area. Pull and lift the liner wall just enough to stretch out wrinkles or pleats. It is easier if you wait until there is 1 to 2 inches of water over the wrinkled area before you try to remove it. This allows the weight of the water to hold liner flat on the ground, keeping out wrinkles after you remove them. Pull any excess liner over the rail and re-clamp in position so that a minimum tautness prevents further wrinkling. Double check around the pool so that you have an even tension on the liner wall down to the liner floor. Do not attempt to lift and pull the liner with more than 4 inches of water in the wrinkled area. Damage to the liner may occur. When the water is approximately 6 inches up the metal wall and covering the cove, there should be just barely enough tension on the liner to control a virtually wrinkle-free installation. Filling Deep Excavated Pools (stretch-in liners only): It is important to remember that the floor of the liner (not the liner wall) must stretch into the excavated area. The bottom edge seam should be located in the cove area all the way around the pool when the pool is full of water. Stretch the liner properly or you will end up with the bottom edge seam somewhere on the bottom of the pool and not enough liner wall to go over the steel wall to complete the installation. If this happens, you may think you * ve received the wrong liner, when in fact the liner was improperly stretched into place. Cleaning Liner: If you decide to drain the pool to clean the liner, or for any reason, you must leave at least 1 foot (12 inches) of water, measured from ground level up the metal sidewall, in the pool. Failure to comply with this warning may void the warranty. Liner Replacement: If you decide to replace the liner, you must have the replacement liner at the pool site and ready for immediate installation. DO NOT leave the pool standing without a liner. Do not attempt to install the replacement liner on a windy day. Severe wind damage to your pool may occur.
Make a return hem as illustrated. DO NOT cutoff excess liner material, as the liner will slip from under the plastic coping, causing liner to fall back into the pool. Smooth the liner against the wall and secure to the top of the wall with plastic coping. Place the stabilizer rails over the coping, alternately telescoping small diameter into large diameter about 6 inches as before. Replace all parts removed in the previous step. Repeat same steps for entire pool perimeter, working just three top rail sections at a time. Do not allow liner to fall back into pool. Finish With pool completely assembled, install skimmer, filter, etc. using the instructions provided with those units. Finish filling pool to the correct level as indicated on your skimmer faceplate. Safety Aboveground pools are designed for swimming and wading only. Do not Dive or Jump! Misuse of your pool may result in crippling injury and/or other dangers to life and health. Do not use slides, diving boards, or any other platform or object which can be used for improper pool entry. Use only an aboveground swimming pool ladder or entry system to enter or exit your pool. Never attempt to swim or reach behind ladders or any other pool entry system. It is the pool owner ' s responsibility to secure the pool against unauthorized, unsupervised or unintentional entry. It is also the pool owner * s responsibility to warn all pool users of the hazards of diving into shallow water: paralyzing injury may result. Juveniles must be supervised at all times by a responsible adult as directed by the U.S. Consumer Product Safety Commission. Always obey all safety rules. Remember, pool safety is everybody * s responsibility. |
Pool Cove is a vital structural element that prevents water pressure from forcing the pool liner out under the bottom rail. Liner manufacturer will not assume responsibility for damage should the cove be omitted. 
Check the pool floor (area inside pool wall) for levelness. Fill in all slight depressions with sifted earth and tamp. Remove all stones and sharp objects. Fill in all footprints on pool floor. Place liner on top of top rail . The liner should have the loose end overhanging the outside of pool by about 12 inches. Hold end and unroll liner down middle of pool as you would a carpet. Do not place the liner side seam over skimmer or return fitting opening. The liner should be centered in the pool, if the liner has 1 seam, that seam should be at the center line of the pool. If the liner has more than one seam, the center section should be placed at the center line of the pool. 
Check flatness of tapered area with 2" x 4" board. Fill in all slight depressions with sifted earth and tamp. Remove all stones and sharp objects. Fill in all footprints on pool floor. Place liner on top of middle top rail at the shallow end of pool. The liner should have the loose end overhanging the outside of pool by about 12 inches. Hold end and unroll down middle of the pool into the deep end. The center seam or center section of the liner must begin at the shallow end and run along the center line of the pool to the deep end. 
Work in both directions from the point where the liner is overhanging. Unfold liner, drape over the top rail and down the sides approximately 24 inches. The liner should be 6” to 12” above the pool floor in the center ONLY. The bottom edge seam of the liner should be inside the pool about 12 inches below the top rails. Correct any bunching or pleating conditions in the liner wall. Inspect liner for open seams. If any are found, promptly return the liner. 
With the liner in position, hold in place by attaching two binder clips over folded cardboard on the underside of each top rail. Carefully cover the end of a garden hose with a sock and tape securely as shown, place it in the pool and begin to fill. As the pool fills, the liner will stretch as the water begins to cover the bottom. At this time, check the sidewall for extreme tautness. Binder clips do not self-release. Any area that feels too tight should be relieved by releasing the binder clips and allowing the liner to feed back into the pool until the desired tautness is achieved. Re-clamp binder clips before you proceed around the pool checking and re-clamping. Remember that you are monitoring a minimum tightness of liner over rail that will control the liner seating itself against the pool floor and up the side with no wrinkles. Continue monitoring the liner tension as the water is approaching and covering the cove area of the pool.
