Component Installation Requirements
Traq Damper Connections
Size the duct connections to attach to the specified portion on the face of the Traq damper module.
For a mitered corner, provide one hydraulic duct diameter between the entering face of the Traq
dampers and the duct turn. For a radius elbow, or sweep, place the elbow directly against the face
of the Traq dampers (see Figure 42).
External Face-and-Bypass Connections
The external face-and-bypass damper modules will require a field fabricated duct to direct the
bypass air into the appropriate module. Duct sizing recommendations are listed in Table 13.
