See Fig. 14 for EconoMi$er IV component locations.
NOTE: These instructions are for installing the optional
EconoMi$er IV. Refer to the accessory EconoMi$er IV instal-
lation instructions when field installing an EconoMi$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. 15.
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. 14.
To remove the component box from its shipping posi-
tion, remove the screw holding the hood box bracket
to the top of the economizer. Slide the hood box out of
the unit. See Fig. 16.
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. 17.
4. Swing out indoor coil access panel and insert the hood
sides under the panel (hood top). Use the screws pro-
vided to attach the hood sides to the hood top. Use screws
provided to attach the hood sides to the unit. See Fig. 18.
