Economizer Hood Assembly - Carrier WeatherExpert Puron 50LC 08 Series Installation Instructions Manual

ECONOMIZER HOOD ASSEMBLY

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 panel. See
Fig. 15.
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. 16.
3. Remove the shipping tape holding the economizer baro-
metric relief damper in place.
4. Insert the hood divider between the hood sides. See
Fig. 16 and 17. Secure hood divider with 3 screws on each
hood side. The hood divider is also used as the bottom fil-
ter rack for the aluminum filter.
5. Attach the post that separates the filters with the screws
provided.
6. Open the filter clips which are located underneath the
hood top. Insert the aluminum filters into the bottom filter
rack (hood divider). Push the filter into position past the
open filter clips. Close the filter clips to lock the filters
into place. See Fig. 17.
7. Install the two rain deflectors on the edge of the hood top
as shown in Fig. 15.
8. Caulk the ends of the joint between the unit top panel and
the hood top as shown in Fig. 15.
9. Replace the filter access panel.
