unit should face into the oncoming airstream. Note: The white plastic base has a round sight
glass hole for observing the lamp inside the duct (the sight glass may be seen above the center
hole in the mounting base in Figure 2). In Figure 2, the unit is installed properly for a
downward air fl ow direction (note that the round sight glass hole will be upstream of the
ballast when properly installed).
