Water temperature too low (below 20ºC). Switch to“SPRING MODE” (button on the front face of the unit).4. Check to make sure there is no air in the cell. If there is,the luminous Flow dot lights up (see “other indications”).N.B.:In “SPRING MODE” the unit works in the same way, the only difference being the reading given by the productiondisplay, which hovers around 85 instead of 100 (normal mode value).5.2 Other IndicationsSTANDBYThe “STANDBY light comes on when the unit is getting ready to start producing chlorine and stays on for about 30seconds at the start of the cycle or when the cell is not producing.FLOWI there is a problem with flow, or gas in the cell, the FLOW indicator lights up, in which case you should check thepump, the filtration system lines and the connection between the gas detection wire and the cell.
