Installing the supporting braces

Install the supporting braces in each of the four locations, having first fitted the recesses with jacks
(Figure 3). Use 4 double acting jacks,4 single acting jacks and 24 screws with a diameter of 10 mm (bag
A). The top screws should be inserted after the height of the bottom screws has been adjusted.
The supporting braces must under no circumstances extend above the top of the pool wall (just
beneath the coping) after adjustment of the supporting brace jacks. On the contrary, it is not problematic
if the top of the supporting braces are 1 or 2 cm below the top of the pool wall.
