Constructed ofdurable polyethylene. Fan coil unit sets directly on topand can be installed with threaded : AIR DISTRIBUTION SYSTEM COMPONENTS4 Plenum DuctThe plenum duct can be run in practically any locationaccessible for the attachment of the supply tubing (seesuggested layouts in Figure ).

9 The plenum is normallylocated in the attic or basement, and it is usually moreeconomical to run the plenum where it will appreciablyshorten the lengths of two or more supply some two-story split level homes, it may be advanta-geous to go from one level to another with the plenumduct. Whenever necessary, either between floors or alongthe ceiling, the small size of the plenum makes it easy to box ESP- 4860 ONLYPLENUMFAN COILUNITPLENUMFAN COILUNITPLENUMFAN COILUNITPLENUMFAN COILUNITFIGURE : PLENUM/TUBING LAYOUT EXAMPLES (FOR GUIDANCE ONLY)The fan coil unit is designed to operate with a total exter-nal static pressure of inches of water column (mini-mum - maximum ).
