The EconoMi$er X has several field-installed accessories available to
optimize performance. Refer to Table 4 for authorized parts and power
exhaust descriptions
INSTALLATION
1. Turn off unit power supply(s) and install lockout tag.
2. Remove the existing unit filter access panel. Raise the panel and
swing the bottom outward. The panel is now disengaged from the
track and can be removed. (See Fig. 2.)
3. Remove the indoor coil access panel and discard. (See Fig. 2.)
4. The box with the EconoMi$er X hood components is shipped with
the EconoMi$er X. Remove hood from packaging. The hood top
and sides are shipped factory assembled.
NOTE:
If the power exhaust accessory is to be installed on the unit,
the hood shipped with the EconoMi$er X will not be used and may be
discarded. Save the aluminum filter for use in the power exhaust hood
assembly.
5. Insert the hood divider between the hood sides. (See Fig. 3) Secure
hood divider with 2 screws (provided) on each hood side. Screws
should go through the hood sides into the divider. The hood divider
is also used as the bottom filter rack for the aluminum filter. On
hood for extra large cabinet install filter divider. (See Fig. 4A.)
6. Set the EconoMi$er X upright. (See Fig. 5.)
7. Slide the EconoMi$er X assembly into the rooftop unit. (See Fig. 5).
On small and large cabinets be sure to engage the rear EconoMi$er
X flange under the tabs in the return-air opening of the unit base.
(See Fig. 6)
IMPORTANT:
These economizer outside air dampers meet ASHRAE
90.1 leakage requirements and must be installed perfectly square.
Verify squareness by measuring diagonally across corners of outside
air damper. Tol/- 1/32”.
8. Secure the EconoMi$er X to unit along side and bottom flanges
using the screws provided.
9. Remove the tape securing the relief dampers in place.
10. Remove and save the 12-pin jumper plug from the unit wiring
harness (located in the upper left corner of the unit). Insert the
EconoMi$er X plug into the unit wiring harness. Refer to Fig. 7 and
8 for wiring diagram.
NOTE: The 12-pin jumper plug should be saved for future use, in the
event that the EconoMi$er X is removed from the unit. The jumper plug
is not needed as long as the EconoMi$er X is installed.
11. If EconoMi$er X will be operating under enthalpy control, replace
the factory installed outdoor dry bulb temperature sensor with
accessory enthalpy sensor HH57AC081. (See Fig. 1.)
12. Remove the indoor fan motor access panel. (See Fig. 9.)
13. The supply air temperature sensor looks like an eyelet terminal with
wires running to it. The sensor is located on the “crimp end” and
is sealed from moisture. Mount the supply air temperature sensor
(provided) to the lower left section of the indoor fan blower housing.
(See Fig. 10.) Use the screw provided and use existing hole. Connect
the violet and pink wires to the corresponding connections on the
supply air temperature sensor. (See Fig. 8.)
