An air terminal device connects to a sheet metal duct run with an integrated reheat coil and an operator. The access door is furnished with the unit. The minimum straight rigid duct length must equal three times the box inlet dimension. If the inlet runout exceeds eight feet, the inlet duct size must increase by two inches in diameter. Electrical devices require a minimum working space depth of three feet and a width of thirty inches or the width of the electrical device, whichever is greater.
