Fig. 2 Ð Weight Distribution and Center of Gravity

Field-Fabricated Ductwork Ð Units are designed for vertical supply/return only. Field-fabricated ductwork should be attached to the roof curb. Supply and return duct dimen- sions are shown in Fig. 3A-3C.

To attach ductwork to roof curb, insert duct approxi- mately 10 to 11 in. up into roof curb. Connect ductwork to 14-gage roof curb material with sheet metal screws driven from inside of the duct.

Secure all ducts to the building structure, using ¯exible duct connectors between roof curb and ducts as required. Ducts passing through an unconditioned space must be insulated and covered with a vapor barrier. Outlet grilles must not lie directly below unit discharge. The return duct must have a 90-degree elbow before opening into the building space if unit is equipped with power exhaust.

Design supply duct strong enough to handle expected static pressures.
