5. . Check the Work Completed So Far
Check one more time that the base of the pool is completely level
and that the pool wall forms a perfect circle in order to avoid prob
-
lems from arising in the subsequent installation of the liner. The
latter can be done by mea-suring the diameter across the pool. Any
errors must be corrected immedi-ately before continuing with the
assembly.
6. Layer of Gravel on the Inside of the Pool (Fig. 4))
A small layer of gravel prevents the liner from being forced out un
-
der the pool wall. Therefore, there should be a layer in the space
between the ground and the pool wall the entire way around. Use
a gravel that does not contain small stones. Ensure that the gravel
layer surface is solid and level the entire way around.
7. Installing the Liner
The pool liner is the most important and most delicate part of the pool. When opening the liner packaging,
it is therefore important that you never use a knife or other sharp instrument. The liner should be kept sepa
-
rate when assembling the pool in order to avoid any accidental damage to the liner caused by tools or metal
edges.
Several people are needed for the installation. The liner can very well be set out and be heated by the sun’s
rays before being unfolded. This makes the material more fl exible and easier to work with. The outdoor
temperature should be bet-ween 20 and 25 degrees when handling the liner. Never install a very cold liner or
a liner whose temperature exceeds 25 degrees as different temperatures can easily warp the fl exible liner
material. This can affect the results of the assembly.
Check and see that there are no holes in the liner. Then spread the liner out as much as possible from the
middle of the pool and all the way around the pool wall. The rugged side of the liner should face upwards/
into the pool.
N.B.: Do not use shoes when the liner is being
spread from the middle out to the pool wall!
The uppermost part of the sides of the liner is held in place
temporarily along the edge of the pool wall with clothespins
or pieces of tape.
Check that the seam between the liner’s bottom and sides is uniform along the length of the fi xed gravel
layer.
Check the diameter of your pool once more and at this point fill it with a maximum of 1-2 cm of water in the
bottom of the pool. No more than that! Adjust/pull the liner the entire way around the pool so that the wrinkles
are smoothed out as much as possible on the bottom and sides. This is best done by standing in the middle
of the pool and smoothing the liner outward toward the sides of the pool. Please note: This can no longer be
corrected once the pool is subsequently filled with more water!
Once the wrinkles in the bottom of the pool are minimized, it is then time to smooth out the wrinkles along the
sides. Make sure that the liner is not pulled too tightly up over the edge of the pool before the pool is filled. It
is still possible to tighten the liner slightly at a water level of approx. 30 cm, so hold off on attaching the top
rail over the edge of the pool.
You can now fill the pool with more water. In the meantime, you should keep an eye out so that the pool does
not lose its round shape. Remove the clothespins and attach the top rail in place on the edge of the pool. The
top rails are attached in the same manner as the bottom rails and they should rest fi rmly in place the entire
way around. The water line must not be any higher than approx. 15 cm from the edge.
Any excess fl oor cover can now be removed/cut away.
