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.
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 safety­alert 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, CAU­TION, 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.

GENERAL

IMPORTANT: These economizers meet all the economizer requirements as laid out in California’s Title 24 mandatory section 120.2 (fault detection and diagnostics).
Catalog No. 04-53480208-01 Printed in U.S.A. Form IIK-CRECOMZR77-03 Pg 1 11-18 Replaces: NEW
Manufacturer reserves the right to discontinue, or change at any time, specifications or designs without notice and without incurring obligations.
IMPORTANT: Read these instructions completely before at­tempting to install accessory economizer.

The EconoMi$er
X system utilizes the latest technology avail­able for integrating the use of free cooling with mechanical cool­ing for packaged rooftop units. The code compliant Jade W7220 control system optimizes energy consumption, zone comfort, and equipment cycling by operating the compressors when the outdoor-air temperature is too warm, integrating the compressor with outdoor air when free cooling is available, and locking out the compressor when outdoor-air temperature is too cold. De­mand controlled ventilation is supported.
This EconoMi$er X 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 available for field installation.
2
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 Table 1-3 for package usage. See Table 4 for package con­tents. See Table 5 for sensor usage.

7. Slide the EconoMi$er X assembly all the way back into the unit until it locks into the horizontal opening of the HVAC (heating, ventilation and air conditioning) unit.
8. Secure the EconoMi$er X mounting flanges to the HVAC unit with the screws provided. See Fig. 6.
9. Install a screw through the pre-punched hole in the EconoMi$er X assembly into the flange on the horizontal duct opening. See Fig. 5 and 10.
10. Remove the red tape securing the relief dampers for ship­ping purposes.
11. On some units, the EconoMi$er X assembly and hood does not reach to the top of the unit. In this case a front blank-off panel must be installed. Install provided front blank-off panel above hood. Screw in place. (See Fig. 8 and 9.)
