• The liner should be well-tensed. Continue with the installation until the water reaches 10 cm below the skimmer.
• Before continuing, make sure that the skimmer flap is well positioned.
• Mark the position of the fixing screws on the liner with a felt-tip pen.
• Position the second square flat seal (G) and the flange (F) against the liner, aligning the holes with the position marks of the screws.
• Fix the flange (F) on the liner with 10 TF screws 5 x 25 starting at the top. The pressure of fixing points on the liner should be constant, (fixing in cross)
• Cut the liner with a cutter from the inside of the skimmer.
• Now you should install the filter.
After finishing the fixing, hollow out the liner following the flange.
