An axonometric detail shows the connection configuration for a chilled water fan terminal unit, including chilled water supply and return piping along with hot water supply and return lines. The unit features an acoustically lined sheet metal supply plenum, an internal balancing damper, and a return air inlet boot configured per project specifications. Flexible ductwork is permitted only in locations where it remains concealed from view, while open exposed ceiling locations require hard-ducted connections to the box. All-thread supports and duct strapping secure the distribution system from the overhead structure, with electrical access provided in accordance with the National Electrical Code.
