Description

Some dampers are provided in multiple panel sections which may require bracing to support: the weight of the panels and/ or system pressure. Bracing to be provided by others. For multiple panel assemblies self-tapping screws should be installed through bracing into frame of damper panel sections. Screw heads should be placed as to not interfere with blade movement. For dampers larger than 60x60 join panels together by bolting through intake damper wrappers. Bolts should be spaced to support the weight of the panels and/ or system pressure. Bolt heads should be placed as to not interfere with blade movement. Dampers are set on an oversized damper tray. Dampers should be mounted on tray as centered as possible. When required the damper can be shifted on the tray to allow for electrical considerations.
