Polysitec® and its surroundings can bring you a wide selection of materials for the construction and equipment of swimming pools made of stainless steel AISI 316L: Drains, gratings, channels, slotdrain, extendable vertical ladders with anti-slip steps. Assisted watertight fillable covers, to be flush with the around pavement, for access to rooms of in-ground treatment plants and underground pool box, (they minimize the noise of the filtration systems.
- A set of FRAME with sealing gasket and hinged refillable TRAY is supplied, with gas pistons, mesh and screws; with allen key, handles for opening and plastic gauges for use in the formwork process.
- Verify the perfect condition of the assembly, it should not have any bumps or deformations on the sides. Check the covers caps of the locking nut housing boxes (they are made of black plastic material).
- Installation and starting up must be carried out by qualified professionals. Handle with caution, there is a risk of entrapment between the frame and the tray.
- Seal the exterior plastic caps of the nut boxes with silicone. Position and level the whole assembly (do not uncouple the tray from the frame), it can be easily opened and manipulated, the gas springs are not mounted.
- The plastic gauges are to guarantee the clearance between the frame and the tray, they must be fixed with adhesive tape on the upper edge of the frame, placed perimetrically and on the opposite side to the hinges put the double. Close the tray and tighten all the closing screws, thus guaranteeing the existence of the nuts in the boxes. The gauges must always be in place when the concrete of the frame and/or the tray is hardening.
- The frame must be perfectly formed perimetrically with NON lightened concrete, the frame can be formed first and then the tray, always coupled and respecting the hardening times. Fill the exterior box caps with concrete. The skirt of the frame can be fixed with stainless steel screws/rods and chemical anchors, filling the gap between the skirt and the walls of the slab with mortar or similar.
- Fix the mesh in the tray and fill it according to the manufacturer’s data, the force of the pistons (N) has been calculated according to the weight of the steel of the tray and the data provided by the client. DO NOT mix concrete with Arlite or similar.
- Remove the Allen locking screws, screwing the handles, open the tray and mount the anti-fall safety lever with automatic locking, it must move freely; install the gas springs with the cylinder body in the refillable tray and adjust the chains so that they act as an opening stop.
- Verify the correct mechanical operation of the whole assembly and the tightness with the Allen screws tightened.
- The set of frame and tray are watertight, therefore it must be provided to the subway or in-ground house an adequate cross ventilation from the lower to the upper zone, natural or forced, we recommend using PVC pipe and fittings of minimum Ø 140mm. each installation is different, you must get an air flow to evacuate gases and avoid condensation, in summer the pool water is hot and in the subway the temperature is lower.
Polysitec® and its surroundings can bring you: Smooth over-raised assisted hatches, are easy to install and are equipped with lock, anti-fall safety lever and hinges, all made of stainless steel AISI 316L; The frame with gasket, supported and sealed on the upper face of the box is fixed on the sides of the semi-buried boxes and containers, has a flange to adapt artificial grass or the surrounding floor. Option: box with thermal insulation.
