TWO-POSITION DAMPER HOOD REMOVAL AND
SETUP — FACTORY OPTION
1. The hood is shipped in knock-down form and assembled
to a metal support tray using plastic stretch wrap.
Located in the return air compartment, the assembly's
metal tray is attached to the basepan and also attached to
the damper using two plastic tie-wraps.
2. To gain access to the hood, remove the filter access
panel. (See Fig. 12.)
3. Locate the two screws holding the metal tray to the base-
pan and remove. In order to remove the screws, it may be
necessary to remove the panel underneath the two-posi-
tion damper. Remove the two screws. Locate and cut the
two plastic tie-wraps securing the assembly to the
damper. (See Fig. 14.) Be careful to not damage any wir-
ing or cut tie-wraps securing any wiring.
4. Carefully lift the hood assembly (with metal tray)
through the filter access opening and assemble per the
steps outlined in Economizer Hood and Two-Position
Hood on page 12.

ECONOMIZER HOOD AND TWO-POSITION HOOD
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 bot-
tom filter 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 fil-
ter rack (hood divider). Push the filter into position past
the open filter clips. Close the filter clips to lock the fil-
ters into place. See Fig. 17.

as shown in Fig. 15.
