Description/
Application
Option CD60 and CD61 - This discharge plenum is shipped separately for
mounting on the top of a Model CAUA 350 or 400 heater without a cooling
coil. The discharge plenum is solid on the top and screened on all four sides
for horizontal discharge. Option CD60 is designed for use in an area where
air can be discharged from all four sides of the plenum. Option CD61 includes
blockoff plates so that the installer can restrict the airflow to only two or three
sides.
Option CD62 - This discharge plenum must be ordered with a Model ACUC
or Option C120, C150, or C180 cooling coil. The discharge plenum is attached
to the top of the cased cooling coil at the factory. The plenum has a solid top
and screened sides for horizontal discharge. Six blockoff plates are shipped
with the plenum for field installation to adapt to the location and provide for the
higher velocity required for a cooling application.
All optional discharge plenums are designed to be used with a screened mount-
ing base, Option AVA2, to create a "packaged stand-alone" upflow system that
circulates building air. However, the discharge plenum may also be used in
place of ductwork in applications that do not have an optional mounting base.
