may be field-converted to horizontal ducted configuration using
accessory CRDUCTCV002A00. To convert to horizontal config-
uration, remove screws from side duct opening covers and remove
covers.

ECONOMIZER HOOD SETUP

NOTE: If the power exhaust accessory is to be installed on the
unit, the hood shipped with the unit will not be used and must be
discarded. Save the aluminum filter for use in the power exhaust
hood assembly.
1. The indoor coil access panel will be used as the top of the
hood. If the panel is still attached to the unit, remove the
screws along the sides and bottom of the panels. See
Fig. 11.
2. Swing out indoor coil access panel and insert the hood
sides under the panel (hood top). Be careful not to lift the
panel too far, as it might fall out. Use the screws provided
to attach the hood sides to the hood top. Use screws pro-
vided to attach the hood sides to the unit. See Fig. 12.
3. Remove the shipping tape holding the economizer baro-
metric relief damper in place (economizer only).
4. Insert the hood divider between the hood sides. See Fig. 12
and 13. Secure hood divider with 2 screws on each hood
side. The hood divider is also used as the bottom filter rack
for the aluminum filter.
5. Open the filter clips, which are located underneath the
hood top. Insert the aluminum filter into the bottom filter
rack (hood divider). Push the filter into position past the
open filter clips. Close the filter clips to lock the filter into
place. See Fig. 13.
