PROCEDURE 6--CONDENSATE DRAIN
To connect drains the cap openings must be removed. Use a knife to start the opening near the tab and using pliers, pull the tab to remove the
disk. Clean the edge of the opening if necessary and install the condensate line. Finally caulk around the lines where they exit the fitting to retain
the low leak rating of the unit.
