Question about an air dryer Harbor freight

Just an update, dryer seems to be working which is a big plus. Tonight when I turned the air on the drain I had ask about pushed water out so I guess I need to get a catch hooked up so it doesnt spit onto the floor! I only had to give my buddy $25 bucks for it so it looks like I did ok!
