– A set of FRAME with sealing O-ring and hinged refillable TRAY is supplied, with gas pistons, mesh and screws; With Allen key, handles for opening and plastic gauges to use in the formwork process.

– Check the perfect condition of the assembly, there should be no bumps or deformations on the sides. Check the nut caps (they are made of black plastic or stainless steel). Check the gas piston heads and shaft.

– Installation and implementation must be carried out by qualified professionals. Handle with caution, there is a risk of entrapment between the frame and the refillable tray.

– If applicable, seal the plastic caps of the nut with silicone. Position and level the entire assembly (DO NOT uncouple, DO NOT remove the tray from the frame), the hinged assembly can be easily opened and manipulated, the gas springs are not mounted.

– The plastic gauges to guarantee the clearance between the frame and the refillable tray come inserted at the factory, fix them with adhesive tape on the upper edge of the frame, place them perimeter and on the opposite side to the hinges put double.

– Close the tray and screw in completely all the closing screws, thereby guaranteeing the existence of the nuts in the frame. It is not necessary to tighten very hard, apply Vaseline to the threads.

– The gauges should always be installed while the concrete formwork of the frame and/or tray is setting. This will prevent friction that could hinder the initial opening. If necessary, the hinge fixing screws can be loosened and then retightened.

– All screws must be fully tightened while the concrete formwork of the frame and/or tray is setting. This ensures proper alignment and a watertight seal.

– The frame must be perfectly formwork around its perimeter with C35/40 concrete (not lightweight). The frame can be formwork first, followed by the tray, always joined together, without removing the fillable tray from the frame and respecting the curing times.

– Fill the exterior of the nut frame caps with concrete. The frame skirt can be secured with stainless steel rods and chemical anchors. Fill the gap between the frame and the internal concrete or brick walls with mortar or a similar material.

– Secure the mesh to the tray and fill it according to the manufacturer’s specifications. The piston force (N) has been calculated based on the weight of the steel in the tray and the data provided by the customer. DO NOT mix concrete with expanded clay aggregate (Arlita) or similar materials.

– Remove the Allen screws securing the tray, screw the handles, open the tray, and if applicable, install the automatic locking safety lever (it should move freely). Install the gas pistons with the cylinder body in the refillable tray and adjust the chains to act as an opening stop and anti-tip device. Verify the correct mechanical operation of the entire assembly and its watertightness with the Allen screws tightened; they do not need to be tightened excessively.

– The frame and tray assembly are watertight; therefore, adequate cross-ventilation from the lower to the upper area must be provided in the underground or buried pool house, either naturally or mechanically. We recommend using PVC pipe and fittings with a minimum diameter of 140 mm. Each installation is different, airflow must be ensured to evacuate gases and prevent condensation. In summer, the pool water is warm, while the temperature in the underground area is lower.
