Installing the liner locking track
Before starting to install the liner locking track, make sure that the structure has been correctly assembled.
To do this, check that the entire periphery is horizontal (use a spirit level), and that the diagonals are equal
in length. If not, rectify these imperfections before continuing.
Start installation of the liner locking track in a corner, as shown in
Figure 18
continue around the periphery
of the pool, taking care with the joins between each 1.18 m length of track. Each section of track must
be perfectly aligned with the two adjacent sections of track to avoid damaging the liner. Joins between
sections of liner locking track do not need to coincide with the structure’s supporting braces.
It may be necessary to trim the track at the end of a
length or width: to do this, measure the distance to
be covered and cut a bar to that length. Remember
to deburr the track after trimming.
The track should be flush with the top of the wooden
structure. Before fixing the liner tracking track into
position, pre-drill the track using the 4 mm diameter
drill bit provided (bag G). Insert the screws provided
at approximately 20 cm intervals (A4 SS torx
countersunk screws 4 × 35 threaded over 20 mm,
bag E). Do not overtighten, to prevent screws from
passing completely through the rail.

Applying self-adhesive gaskets
Mount the gaskets on the skimmer and the return fitting.
Figure 19 –
Mounting the throughwall flanges
The liner must be installed with the next 48 hours. If this is not possible, delay installation of the gasket
until just before the liner is installed.
Make sure that the gaskets are correctly positioned and applied. It will be difficult to rectify an omission
or mistake after the liner has been fitted. Check that the holes in the various pool fittings (skimmer,
return fitting) and the holes in the wooden wall are correctly aligned with the holes in the gaskets.
The rest of the part (gasket and flange) will be mounted after the liner is installed, to ensure leaktightness
at the two throughwall flanges.
