See Fig. 16 for EconoMi$er IV component locations.
NOTE: These instructions are for installing the optional
EconoMi$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. 17.
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 in the position shown in Fig. 16.
The optional EconoMi$er2 with 4 to 20 mA actuator
signal control does not include the EconoMi$er IV
controller. 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. 18.
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.

the hood. Remove the screws along the sides and bot-
tom of the indoor coil access panel. See Fig. 19.
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.

barometric relief damper in place.

the hood top. Insert the aluminum filter into the bot-
tom filter rack (hood divider). Push the filter into po-
sition past the open filter clips. Close the filter clips
