• Key points on the partially sunk swimming pool or on the inground installation
Before you begin to assemble the pool, make sure that you have all the necessary parts.
IMPORTANT: If you choose to partially sink your swimming pool, make sure that you embed the pump and the filtration unit at the same level as the pool in an
enclosed, waterproof place. To ensure that the filtration unit works efficiently, it must always be positioned below the level of the water.
CAUTION: In the case of a partially sunk swimming pool, before you put any water into the pool, you must have a safety system in place for the prevention of
drowning, which complies with your national safety standards
During the excavation phase make sure that the side walls are secured.
• Install the waterproofing sheet (not provided) on the outer sides of the pool to drain off rainwater. The height of the liner must correspond to the level of the bank
of gravel.
• The dimpled side is to be placed against the pool structure, leaving an air gap between the wet slope and the pool walls. The dimpled structure provides for a
convenient distribution of the slope pressure, und at the same time for a low point load (compres¬sive strength: 250 kN/m²)
• Fill the pool with water before backfilling the circumference with gravel. Fill the circumference of the pool with gravel. Be careful not to destort the structure when
backfilling.
