4290028771rev00INSTALL AND CONNECT THE FREE AIR VENTED DRAIN LINESThe drain outlets and the drain vent at the top of the unit and must be free airvented to equalize the pressure in the with the atmosphere.Generating steam causes pressure to increase in the unit; cold water flow into thecondenser creates a vacuum (low pressure) in the condenser. Without a free airvent, eitherhigh or low pressure in the compartment will cause malfunction or damage.• Pressure build up in the steamer will cause steam and hot water leakage around the door.• A vacuum will implode the steamer and cause permanent physical damage.Refer to Figure 2-4, and the dimension drawings (Figure 2-2). The drain outletdischarges exhaust steam and hot condensate from the oven/steamer.The drain exhaust vents ( and ) and a 1 inch/25 mm minimum clearance between thedrain opening and floor provide the with free air venting.Furnishing and installing the drain lines and fittings is the responsibility of the owner and/orinstaller. Figure 2-4 illustrates a drain layout recommended by the Manufacturer.The drain line: Use a heat-resistant plastic pipe (not flexible), installed without loops orkinks and no longer than 2 metres with a slope of no less than 4 degrees, or realize a drainline with a gravity flow away from the unit. Drain line must not be connected to the drainlines of any other equipment. In compliance with current standards, the drainage pipingmust not be connected in a straight line.
