Page 3: Installing Multiple Section Damper Assemblies
Installing Multiple Section Damper Assemblies A damper assembly is not restricted to a maximum number of sections, but must not exceed the section sizes and assembly sizes shown in the Maximum Assembly Table. Some multiple section high damper assemblies require additional structural support between the damper frames. The following multiple section high damper assemblies require the use of either a support mullion between the damper frames as shown in Figure 1 or individual sleeves around each row of dampers as shown in Figure 2: •... -

Page 6: Damper Maintenance
Damper Maintenance Dampers do not typically require maintenance as long as they are kept dry and clean. If cleaning is necessary, use mild detergents or solvents. If lubrication is desired for components such as axle bearings, jackshaft bearings and jamb seals, do not use oil-based lubricants or any other lubricants that attract contaminants such as dust. Dampers and their actuator(s) must be maintained, cycled, and tested a minimum in accordance with: •... - Page 7 Notes Smoke Dampers...
