Contractor shall provide exterior isolation dampers on the West wall of the emergency generator room in our Syracuse facility. Contractor shall furnish all parts to install the dampers in the existing plenum openings in the wall for the intake and exhaust. Dampers will be broken into sections that will fit through existing access doors and able to be reassembled in place. The intake dampers, labeled on drawing as Damper1, consist of 3 plenum openings 83 ½ X 145 , each set of dampers will be separated into 4 equal sections for installation, and hardware is to be provided to join the sections together. The exhaust dampers, labeled on the drawing as Damper 2, consist of one plenum opening of 107 ½ X 143 ½ , this set of dampers will be separated into 4 equal sections for installation, and hardware is to be provided to join the sections together. The other exhaust damper, labeled on the drawing as Damper 3, consist of one plenum opening of 148 ½ X 143 ½ , this set of dampers will be separated into 6 equal sections for installation, and hardware is to be provided to join the sections together. Dampers shall bear the AMCA Certified Ratings Seal for Air Performance Air Leakage and Efficiency in accordance with AMCA 511 Dampers must meet AMCA certified energy performance ratio of at least 593% and be constructed in the USA. Dampers blades are to be constructed of extruded aluminum internally insulated, thermally broken with silicone seals. All blades are to opposed style in a horizontal orientation. Damper frame will made of aluminum with structural channel for stability Damper linkage will be constructed with 316 stainless steel and concealed in frame out of the airstream to prevent corrosion from salt. Dampers will fail to the open position. Actuators will be 24v power closed spring open with a minimum torque of 270 in/lbs., and direct coupled. One actuator will be on each section of dampers with hardware to mount them. Dampers will have all jack shafting and actuator linkage with schematic and assembly instructions.
