- 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.

- De
fi
ne the minimum width F of the roller trench using
the following method:
• Determine the inner width allowing the complete
rolling of the cover using the table. Take into account
the radii, circular cuts and the thickness of a masonry
par
ti
ti
on wall that is wider than the beam, which would
be unusable zones for
fi
tti
ng the cover.
• Check that:
If there is a duckboard laid on the edges of the pool:
F < Duckboard (in mm) - 25 mm.
In the case of a duckboard covering the beam and laid
on the edge:
F < Duckboard - 25 mm - 100 mm.
If a duckboard is not laid on the rear edge:
F < Duc overlap of the coping.
1.3.2 Squaring
checks
Fig. 5
- In order to correctly place your roller perpendicular to
the pool lengths: measure the diagonals.
- Make a mark (1) on the pool liner at the level of the edge
at the centre of the rolling trench.
- Measure a precise length "A" of 1 m less than the length
of the pool and make a mark (2), at the end of A on the
pool liner.
- On the opposite length make a mark (3) opposite mark
(1).
- Carry over the "A" measurement from (3) in order to
place mark (4).
- Measure the distance "B1" between (1) and (4) and
measure the distance "B2" between (2) and (3).
- If B1 and B2 are equal con
ti
nue with the next step,
otherwise correct the posi
ti
on of marks (3) and (4) and
start the opera
ti
on again un
ti
l B1 = B2.
