The model you have chosen has been especially designed for simple and rapid installation, but some precaution is necessary for the good use of your pool. Before starting with the installation and assembly of your pool, consider the current local regulation about on ground and in ground pools.

  • Page 6 Learn about wood WOOD: A LIVING MATERIAL Wood is a natural product, the fissures visible on the edges of the wood are completely normal and do not modify the resistance characteristics of the same. Wood is always a malleable material (from 3% to 4% of dimensional variations) with humidity and temperature oscillations. Therefore, small cracks can appear and in order to limit later deformations, the technical criteria have been respected regarding the design, the choice of sections, and of packaging and the fixing methods.

The well will be excavated before the construction of the pool to avoid that the excavations fill with water during the works. It should be near the pool, a few centimetres lower than the deepest point of the same and reach up to the surface.

  • Page 40 Landfill (for fully or partially in-ground pools) In fully or partially in-ground pools, a gravel landfill is necessary to favour perfect draining. The landfill of a pool can seem a mere formality, because a first sight there are no special technical difficulties. Nevertheless, it is a more delicate operation than what it seems, for which certain precautions are necessary.
  • Page 41 INFORMATION The drainage allows the continuous evacuation of water, at the foot of the pool and, therefore limits the rising of water by capillary attraction towards the upper part of the works, where air and soil interact to produce fungi or rot (lower diagram) The absence of draining causes water to ascend by capillary action that can be important and permanent, which favours the attacks of air / water interaction (lower diagram).

  • Page 50: Putting Into Service

    Putting into service During the first use, you should wash the filter (check the filer system maintenance). Filtering is a mechanical treatment that allows cleaning the pool water by means of eliminating the impurities and contaminating particles. The hydraulic circuit and water purifying group is an essential element for the optimal operation of the filtering system. The filtering system should be coherent: The filter dimensions should be proportionate to the volume of water in the pool and to the pump performance.
  • Page 51 Maintenance of the filtering system CLEANING THE FILTER Perform this procedure each time you need to clean the filter. When the pressure increases 0.2 bar regarding the starting pressure you need to clean as follows. Make sure that you have correctly installed the emptying tube (not included) in the collector of the multi-directional flap, so that it allows water evacuation when the sand or filer is cleaned.
  • Page 52: Sand Filter

    Sand Filter This is the oldest of filtering systems. The filtered water passes through the sand (calibrated silicon) that retains all impurities. This type of filter is equipped with a multi-directional flap that allows easy manipulations and cleaning. DIFFERENT POSITIONS OF THE MULTI-DIRECTIONAL FLAP (4 OR 6)*: When you perform changes the position of the multi-directional flap that pump should always be stopped, without risking seriously damaging the filter and cancelling the guarantee.
  • Page 53: Wintering

    4. EMPTYING POSITION / DRAIN (OR WASTE): Position to evacuate the water or for emptying the pool. In this case, the water does not pass through the filter, it goes directly to the drain. Skimmer 5. CLOSED POSITION: This position does not allow the water to pass and is used to put the pool into complete wintering when the filtering stops. Skimmer 6.
  • Page 54 MAINTENANCE AND USE RESPECT THE ENVIRONMENT DO NOT TAKE APART THE POOL UNLESS IT IS STRICTLY NECESSARY. IF YOU DO SO, PLEASE REUSE THE WATER. WATER IS A SCARCE GOOD. - Switch on the filter system once a day in to insure a complete water volume renewal and never do it when somebody is in the pool (see filter manual).
  • Page 55 - Chlorine treatments: Consist in increasing the chlorine level until approximatively 20 ppm to eliminate germs and seaweeds. This process has to be done only when the pool water comes from rivers or ponds, … or if it stayed a long time without any treatments. - Checking: Check at least once a week the chlorine levels (use a chlorine and pH analyser).
