NOTE:
These instructions are for installing the optional
EconoMi$er IV only. Refer to the accessory EconoMi$er IV
installation instructions when field installing an EconoMi$er IV
accessory.
1. To remove the existing unit filter access panel, raise the
panel and swing the bottom outward. The panel is now
disengaged from the track and can be removed. (See
Fig. 22.)
2. The box with the economizer hood components is shipped
in the compartment behind the economizer. The
EconoMi$er IV controller is mounted on top of the
EconoMi$er IV. To remove the component box from its
shipping position, remove the screw holding the hood box
bracket to the top of the economizer. Slide the hood box
out of the unit. (See Fig. 23.)
IMPORTANT: 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.
3. The indoor coil access panel will be used as the top of the
hood. Remove the screws along the sides and bottom of
the indoor coil access panel. (See Fig. 24.)
4. Swing out indoor coil access panel and insert the hood
sides under the panel (hood top). Use the screws provided
to attach the hood sides to the hood top. Use screws
provided to attach the hood sides to the unit. (See Fig. 25.)
5. Remove the shipping tape holding the economizer
barometric relief damper in place.
6. Insert the hood divider between the hood sides. (See
Fig. 25 and 26.) 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.
7. 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. 26.)
8. Caulk the ends of the joint between the unit top panel and
the hood top. (See Fig. 24.)
