Follow all safety codes.
Wear safety glasses and work gloves.
Use care in handling and installing the accessory. It is important to recognize safety information. This is
the safety-alert symbol . When you see this symbol on the unit and in instructions or manuals, be alert to the poten­tial for personal injury.
Understand the signal words DANGER, WARNING, CAU-
TION, and NOTE. These words are used with the safety-alert symbol. DANGER identifies the most serious hazards which will result in severe personal injury or death. WARNING signi­fies hazards which could result in personal injury or death. CAUTION is used to identify unsafe practices, which may re­sult in minor personal injury or product and property damage.
NOTE is used to highlight suggestions which will result
in enhanced installation, reliability, or operation.
WARNING
ELECTRICAL SHOCK HAZARD Failure to follow this warning could cause personal injury
or death. Before performing service or maintenance opera­tions on the unit, always turn off main power switch to unit and install lock(s) and lockout tag(s). Unit may have more than one power switch. Ensure electrical service to rooftop unit agrees with voltage and amperage listed on the unit rat­ing plate.
CAUTION
CUT HAZARD Failure to follow this caution may result in personal injury. Sheet metal parts may have sharp edges or burrs. Use care
and wear appropriate protective clothing, safety glasses and gloves when handling parts and servicing roof top units.
CAUTION
Failure to follow this caution may result in personal injury and damage to the unit. Cover the duct opening as a precau­tion so objects cannot fall into the return duct opening. Be sure to remove the cover when installation is complete.

SAFETY CONSIDERATIONS

Installation of this accessory can be hazardous due to system pressures, electrical components and equipment, and equipment locations (such as a roof or elevated surface). Only trained qualified installers and service technicians should install, start up, and service this equipment.
When installing this accessory, observe precautions in the literature and on any labels attached to the equipment and all other safety precautions may apply.
Manufacturer reserves the right to discontinue, or change at any time, specifications or designs without notice and without incurring obligations.

The EconoMi$er® X system utilizes the latest technolo­gy available for integrating the use of free cooling with me­chanical cooling for packaged rooftop units. The code com­pliant Jade W7220 control system optimizes energy con­sumption, zone comfort, and equipment cycling by operating the compressors when the outdoor-air temperature is too warm, integrating the compressor with outdoor air when free cooling is available, and locking out the compres-

GENERAL

sor when outdoor-air temperature is too cold. Demand control ventilation is supported.
This EconoMi$er X system can be used with 1 or 2 speed indoor fan motor units. (All other speed settings listed are for future use.)
The EconoMi$er X system utilizes gear-drive technology with a direct-mount spring return actuator that will close upon loss of power. The EconoMi$er X system comes stan­dard with fault detection and diagnostics (FDD), an outdoor air temperature sensor, and mixed air temperature sensor (al­so called supply air temperature sensor). Outdoor enthalpy, indoor (return) dry bulb or enthalpy, and CO
sensors are
2
available for field installation.
Standard integrated barometric relief dampers provide nat­ural building pressurization control. An optional power ex­haust system is available for applications requiring even greater exhaust capabilities. The power exhaust set point is adjustable at the EconoMi$er X controller.
See Tables 1-3 for package usage. See Table 4 for package contents. See Table 5 for sensor usage.
IMPORTANT: These economizers meet all the econo­mizer requirements as specified in ASHRAE 90.1, IECC and California’s Title 24. Economizer must be installed square to avoid damper leakage or damper binding. Squareness tolerance is ±
1
/32 inch.
IMPORTANT: Read these instructions completely before attempting to install the accessory economizer.

Compliance

Economizers meet California Energy Commission Title 24 prescriptive section 140.4 (damper leakage etc.), and mandato­ry section 120.2.i for Fault Detection and Diagnostic controls.
Economizers meet ASHRAE 90.1 damper leakage require­ments and meet Fault Detection and Diagnosis requirements.
Economizers meet IECC damper leakage and Fault Detec-
tion and Diagnostic requirements. NOTE: IECC requires differential return air sensor, which must
be ordered separately. See Accessory CRDIFRASN01A00.

INSTALLATION

NOTE: If installing economizer on 48/50LC 07-12 units, see “Instructions for 48/50LC 07-12 Units Only” on page 10.
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. Set the filter door aside for re-installation later.
