Connect the condensation water drain tube to the outletsituated on the right-side panel of the DMP501.1. Connect the silicone tube to the metal tube protruding from theright side of the DMP501 Dewpoint Sensing Unit.2. The tube end must be placed at least 300 mm below the sensingunit bottom level, in a drain or in a small vessel where thecondensed moisture can be safely drained. The amount ofcondensed moisture is small, typically tens of milliliters per 24 hof operation.WARNING Do not assemble the instrument in a location where condensed waterdripping out of the system could cause a hazard, such as above high-voltage power supplies.
