To my way of thinking they should provide a secondary condensation line piped to a conspicuous point or a switch that will shut down the unit if it senses water.

JayHawkInspector,

The float switches are what we typicaly see on the condensate line installs around here. The float switch is cheaper

to install than asking the plumber to run a secondary drain line.
