Page 5: Waterwash Components
Fire Mode (Optional): The waterwash system also provides water spray for the exhaust plenum when the system is in fire mode. This is in addition to the hood’s automatic fire suppression system. When the fire suppression system discharges, it activates the waterwash system (without the detergent) and the optional continuous cold water mist to spray water within the exhaust plenum and turns on the fan circuit. - Page 6 SYSTEM COMPONENTS: Hood: The hood is shipped from the factory prepiped and ready to install. All waterwash components within the hood are complete and ready for connection to hot water, electrical sources, the sanitary sewer drain and optional cold water. All piping to and from the waterwash control station and the hood is by others. Wiring from the control panel to the hood (for lights) is by others.
