Component Installation
The components in the air handler may have installation
requirements that could affect the unit’s performance.
Dampers
Dampers are factory-installed and adjusted and can be
found in mixing box/economizer sections. There are two
damper blade configurations available: parallel-blade and
opposed-blade.
Traq™ dampers are another type of damper available in
mixing box sections. Traq dampers have only one blade
configuration - opposed. They have two control
applications available - standard Traq dampers and low-
flow Traq dampers. Low-flow Traq dampers are always not
linked and consist of two damper sets - one set for
minimum outside air measurement and one set for
economizing. The singe low-flow Traq damper will have a
VCM. The economizing damper will not.
The 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 13.
Mixing section and economizer 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 section will be the responsibility of
the installing contractor.
The economizer that meets or exceeds all mandatory
requirements prescribed by Title 24, including but not
limited to:
• 5-year parts only warranty
• Successfully tested to 60,000 actuations
• Less than 10 cfm/sq.ft. of damper leakage at one inch
w.g. per AMCA 500L
