2 Series fan-coil units are single room air conditioners designed forcooling and heating load capabilities of 400 to 800 cfm. Units can beselected with either one hydronic circuit (2-pipe) or two hydroniccircuits (4-pipe) coil Basic Series Fan-Coil design is for the market that requires onlythe basic features of our standard UniTrane Fan-Coil. Units are horizon-tal concealed and are available with an exposed fan, plenum, or ceilingaccess accessories include a remote-mounted fan speed switch,ball valves, and control InformationDrain panFigure 1.
