Installation, use, maintenance manual - DualSun solar heating system for individual swimming pools 1.3.2. PVC stripper and glue It is important to strip and glue each PVC element well. Comply with the manufacturers' recommendations for use. Immediately after stripping each part, first glue the fitting thoroughly, then the end of the pipe. Fit the end of this pipe into the fitting by turning slightly so that the glue is evenly distributed and until each element is properly in place. -
Page 6: The Dualsun Spring Hybrid Panel
• Electricity through photovoltaic cells, • Heat via a heat exchanger, completely integrated into the panel. This heat is captured at the DualSun SPRING panel exchanger by a heat transfer fluid. The latter transports the heat to the heat transfer device, which restores the calories of the heat transfer fluid to thermal storage or directly to the tank to be heated. -

For aesthetic reasons, it is possible to paint PVC pipes: take a good quality paint, anti UV if possible. 2. Selection of the diameter of the transfer pipes We have defined a chart to choose the diameter of the pipes according to the number of DualSun SPRING panels connected to the solar swimming pool heating system. -
Page 13: Operation Of The Filtration Pump And Verification Of Its Characteristics
For example, for a swimming pool water temperature of 24 ° C, the filtration time must be equal to 12 hours daytime. The solar heating system will bypass the filtration flow, but it is not intended to activate the filtration. Normally during the period of use of the swimming pool, the ambient temperature is higher than the tempera- ture of the swimming pool, therefore the filtration flow is systematically bypassed in the panels to recover the available energy. -
