As soon as the water level reaches a certainpoint, the float lifts, opening the outlet nozzle. As the water is evacuated into the vacuum system and the water levelfalls, the float shuts the outlet again.The position of the float can be adjusted by turning the adjusting screws.MaintenanceCheck periodically that the valve is not leaking.Every year:The scupper valve housing as well as the float (5439523) and the nozzle (5439534) should be cleaned.Every five years:The position of float (vacuum tightness) should be checked at -20kPa vacuum. The position of the float is corrected byadjusting the adjusting screws (5439556).INLETINLETLoose flange for weldingFloatNozzleScupperhousingOUTLETGratingAdjusting screwsINLETEVAC reserves the right to make alterations to this specification without prior notice.© Copyright Evac Oy.
