6. If damper actuator is to be mounted out of the airstream, the extension pin should extend approximately
6 inches (152mm) beyond the frame. On jackshafted units, the jackshaft should extend through the jackshaft
bearing assembly and approximately, 6 inches (152mm) beyond the frame.
7. Individual damper sections, as well as entire multiple section assemblies must
be completely square and free from racking, twisting, or bending. Measure diagonally
from upper corners to opposite lower corners of each section (see Figure 3 & 4).
8. Damper blades, axles, and linkage must operate without binding. Before system operation,
cycle dampers after installation to assure proper operation. On multiple section assemblies,
all sections should open and close simultaneously.
Quick Connect frame
1. These instructions apply to quick connect frame attaching to a TDC or TDF flange system.
2. To seal the two flange systems together Neoprene or Butyl gasket may be applied to the mating surfaces
(Figure 5).
3. Align the quick connect frame and flange system together. An optional 3/8 in. (9mm) bolt may be used in the
corners to help with the alignment. These bolts do not have to be removed.
4. Install the metal cleat (Figure 6) or #10 tek screw with following recommended spacing:
• Width or height less than 24 in. (610mm); use one cleat or screw per side
• Width or height 24 in. (610mm) to less than 36 in. (914mm); use 2 cleats or screws per side
• Width or height 36 in. (914mm) to less than 54 in. (1372mm); use 3 cleats or screws per side
• Width or height 54 in. (1372mm)to less than 72 in. (1829mm); use 4 cleats or screws per side
• Width or height 72 in. (1829mm) or greater; use 5 cleats or screws per side.
