If the pump is switched off or if the flow drops below the minimum value, the sensor opens the circuit and cuts the power supply.<\/p>\n<ul>\n<li>Prevents devices from running dry when valves are closed or the pump is stopped.<\/li>\n<li>Helps avoid damage to UV-C lamps, quartz sleeves and heater elements caused by overheating.<\/li>\n<li>Supports safer operation in pools with variable speed pumps or bypass circuits around certain equipment.<\/li>\n<\/ul>\n<h3>Installation guidelines<\/h3>\n<ul>\n<li>Install the 63 mm tee in a vertical section of the return pipe, respecting the indicated flow direction on the sensor body.<\/li>\n<li>Ensure the water flow always moves from bottom to top through the sensor tee to minimise the risk of air pockets.<\/li>\n<li>Use appropriate PVC cleaner and glue when integrating the tee into rigid pipework and allow full curing before pressurising.<\/li>\n<li>Mount the control box in a dry, well ventilated technical room, protected from direct splashes and sunlight.<\/li>\n<li>Connect the Flow Switch Plus with its 230 V plug to a grounded socket that is suitable for pool equipment and protected by an RCD.<\/li>\n<li>Plug the UV-C unit or other protected device into the output of the Flow Switch Plus according to the manufacturer instructions.<\/li>\n<\/ul>\n<p>After installation, start the filtration pump and check that the connected device switches on only when adequate flow is present and switches off promptly<br \/>\nwhen the pump is stopped or the flow is interrupted.<\/p>\n<h3>Use, safety and maintenance<\/h3>\n<ul>\n<li>Periodically inspect the flow sensor area for deposits or debris that could affect movement or sensitivity.<\/li>\n<li>Check that unions and glued joints around the tee remain watertight and free from leaks.<\/li>\n<li>Verify the operation of the safety function at the start of each season by stopping the pump and confirming that the protected device switches off.<\/li>\n<li>Do not exceed the specified maximum current rating when connecting equipment to the Flow Switch Plus.<\/li>\n<li>Have any electrical modifications in the technical room carried out by a qualified electrician in line with local regulations.<\/li>\n<\/ul>\n<p>With correct installation and periodic checks, the Blue Lagoon Flow Switch Plus 230 V type F 5056579 provides an effective additional safety layer for UV-C units,<br \/>\nheaters and other electrical devices in the pool system, helping to extend their service life and reduce the risk of damage caused by insufficient water flow.<\/p>","protected":false},"excerpt":{"rendered":"<p>Blue Lagoon Flow Switch Plus 230 V type F 5056579 The Blue Lagoon Flow Switch Plus 230 V type F (article 5056579) is a compact flow sensor and safety switch for pool installations.
