INSTALL AND CONNECT THE FREE AIR VENTED DRAIN LINES
The drain outlets and the drain vent at the top of the unit and must be free air
vented to equalize the pressure in the with the atmosphere.
Generating steam causes pressure to increase in the unit; cold water flow into the
condenser creates a vacuum (low pressure) in the condenser. Without a free airvent, either
high 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 outlet
discharges exhaust steam and hot condensate from the oven/steamer.
The drain exhaust vents (
and ) and a 1 inch/25 mm minimum clearance between the
drain opening and floor provide the with free air venting.
Furnishing and installing the drain lines and fittings is the responsibility of the owner and/or
installer. 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 or
kinks and no longer than 2 metres with a slope of no less than 4 degrees, or realize a drain
line with a gravity flow away from the unit. Drain line must not be connected to the drain
lines of any other equipment. In compliance with current standards, the drainage piping
must not be connected in a straight line.
