Safety information, installation and maintenance For full details see the Installation and Maintenance Instructions (IM-P017-11) supplied with the product. Installation note: The AE50S should be installed vertically with the inlet at the bottom. We recommend piping the discharge to a safe visible point or drain via an air break. Installation in superheated water: For superheated water applications we recommend that 1 m to 2 m (3.28 to 6.56 f)tof ¾" vertical pipeline be fitted prior to the inlet of the vent. On superheated water systems the outlet pipework must be sized to accomodate any flash steam created during discharge. Direct the outlet pipework to a safe point of discharge where there is no risk of injury to personnel or damage to property.
