1.1.2 Overfl ow
Fig. 2
Plan to control the water level at 12 cm below the
edge using a ø 50 mm overfl ow which is independent
of the skimmers and an automatic fi ll.
1.1.3 Skimmer
When possible, plan to place the skimmers on
the pool widths and not on the lengths in order to
facilitate the movement of the cover.

1.2.1 In order to correctly place your roller perpendicular
to the pool lengths: measure the diagonals.
1.2.2 Make a mark (1) on the pool lining at the level of the
edge opposite the cable exit.
1.2.3 Measure a precise length "A" of 1 m less than
the length of the pool and make a mark (2), at the
extremity of A on the pool liner.
1.2.4 On the opposite length make a mark (3) opposite
mark (1).
1.2.5 Carry over the "A" measurement from (3) in order to
place mark (4).
1.2.6 Measure the distance "B1" between (1) and (4).
1.2.7 Measure the distance "B2" between (2) and (3).
1.2.8 If B1 and B2 are equal continue with the next step,
otherwise correct the position of marks (3) and (4)
and start the operation again until B1 = B2.
