Component Installation Requirements
Damper Modules
Dampers are factory-installed and adjusted and can be found in mixing box/economizer modules,
internal or external face-and-bypass modules, and face damper modules. There are two damper
blade configurations available: parallel-blade and opposed-blade. Traq™ dampers are another
type of damper available in mixing box modules.
The M-Series air handler is available with factory-mounted controls or end devices. If the unit is not
ordered with controls or end devices, it is the installer’s responsibility to provide and install the
damper actuators. Size the actuators according to
Table 11
.
Mixing modules and face-and-bypass dampers are designed for the damper actuators to be direct
coupled and installed in the air stream. If other provisions are required, modifications to the
module will be the responsibility of the installing contractor.
For set-screw torque settings, see
Table 12
