Description/

Application

The optional mixing box for the Model CAUA heater is designed to provide the system

with a supply air mixture of return air and outside air. (NOTE: Application with a mixed

air temperature below 35°F (2°C) requires that the CAUA unit be ordered with Option

AD4.) The mixing box is available in an assortment of congurations with a selection

of actuators and controls for both heating and cooling mode (for units equipped with

a cooling coil). The mixing box is completely assembled at the factory for eld attach-

ment to the rear of a Model CAUA heater. It is recommended that the furnace be in its

nal location before attaching the mixing box.

able door panels provide for lter access from either end of the cabinet. If the box was

ordered with lters (Option AW9 or AW11), it is shipped with the lters installed. (For

replacement lter sizes, see page 4.)
