Before pulling the liner up against the wall, insert a vacuum
cleaner hose down into the pump return hole to approximately
15 cm (6") from the ground.
Maintain the hose in place with adhesive tape. Don't forget to
block the skimmer hole with adhesive tape to prevent air from
leaking in.
Place the unfolded liner in the center of the pool area. Make sure
you wear light, flat-soled shoes to walk on the sand as the slight-
est heel mark could be visible once the pool is filled.
Carefully unfold the liner (u-bead or overlap), bringing the bot-
tom-sidewall seam close to the wall base. Make sure that the
side with the protruding seams faces downward or that the pat-
terned side faces upward.
Hang the u-bead liner on the top of the wall and install the round
stabiliser to secure.
Lift up a section of the overlap liner over the top of the wall leav-
ing a 10 cm to 15 cm (4" to 6") fringe outside the wall.
Secure the liner with a plastic coupler.
At this point, the liner may be too tight, making it difficult to
drape the overlap or, on the contrary, too loose. In such cases,
you will have to redistribute the tension in the liner by remo-ving
some of the couplers and readjusting the liner.
Install the joiner plates on top of each upright then install metal
screws at the top of the support post, making sure the support
posts are perpendicular to the ground.
NOTE: For the straight section don’t forget to fix the joiner plate
to the support post with two (2) screws.

You can now spread approximately 10 cm (4") of compacting
sand all around the inside base of the wall in order to protect the
liner from the cutting edges of the bottom wall tracks and the
stone dust (if applicable). Or install a prefabricated cove, if avail-
able.
SAND BASE FINISHING
Level finishing sand one last time. Make sure that any sharp
stones, debris or roots have been removed from the surface. For
better protection, spray sand with water and pack it once more
until the base is nicely even.

Attach the uprights to the bottom joiner plates with two or three
metal screws. You will find them in the hardware bag depending
of the model.
Uprights must be installed outside the flanged part of the joiner
plate.
Note : Top and bottom joiner plates are the same.

Begin inserting the wall into the bottom wall tracks in the middle
of a joiner plate.
At first, the wall is kept in place with one or two support bars (or
extra persons). One person uncoils the wall on a beam or a
plank, while a second person inserts it in the bottom wall tracks.
Do not uncoil more than 3 m (10') of wall before you install a
support bar to reinforce the structure.
Once the wall is completely uncoiled, you may find that it is too
long or that both ends do not meet by a few centimetres. If such
is the case, you must gently push the wall in or out. If this does
not work, roll up the wall again, realign the grooves and uncoil
the wall again. If the spread is too wide, measure the wall and
check it against the following chart.
When you prepare to join the ends of the wall, make sure the end
that is reinforced by the fold is inside the circle, facing the liner
and that the other end faces outward (Illustration 5.1).
When the wall joint is secured, install the round stabilisers on top
of it.
IMPORTANT: Due to the enormous
pressure exerted by the water on the
steel wall, it is absolutely essential that
all the bolts are screwed in tigh-tly and
no hole is left open. All bolt heads
must be inside with washer and nut
outside. Cover all bolt heads with
heavy fabric tape.
