NOTE :For proper operation all dampers must be installed square & free from racking. All damper operators mustbe installed on the linkage side; all opposed blade dampers must be operated from a power blade or driveshaft. Any dampers installed over 1 section wide and 1 section high shall have appropriate bracing at

every horizontal mullion and vertical bracing min. 80 O.C. Dampers are designed for operation with bladesrunning horizontally.
