The UV box has a vacuum pump built in -- there are four UV tubes in the
bottom, covered with a sheet of glass, then four in the top with a sheet of
flexible transparent plastic over them. When the timer is started, the vac
pump runs for a minute or so, then the tubes are struck and the countdown starts.
