• outdoors
• basin tailpiece
• above flood rim of fixture
• above floor drain
auxiliary condensate line (should discharge where it will be noticed - e.g., over front door)
The primary and auxiliary condensate lines should not "Y" together as both could then be affected by a blockage

Generated explanation

The illustration shows an attic evaporator coil housing connected to return and supply ductwork, with arrows indicating airflow through the unit. A trapped primary condensate line drains the unit's internal condensate tray, with several possible discharge locations listed. An auxiliary condensate tray beneath the housing has its own separate drain line, which is to discharge where occupants will notice it, such as over the front door. An annotation warns against joining the primary and auxiliary lines with a Y connection because a blockage could affect both.
