Application Considerations
Partially Exposed Unit
Another example of a partially exposed unit ventilator includes a fresh air upper back, with a return
air lower back, combined with a bottom, double-deflection discharge. This application requires
field supplied duct work to the added to the return air side of the unit ventilator.
Partially Exposed Unit
A ducted discharge option is available to support the many design layouts expected of the
mechanical system. The location of the discharge ducting could be critical during installation due
to such issues as recessed lighting. Trane provides three selectable ducted discharge locations to
reduce interference of other trades on the job site.
Note: When a high ESP motor is used on the ducted system, the return air should enter through
a rear duct connection. The return-air should pass through a lined return air duct with at
least one 90° elbow to lessen airflow noise.
