Introduction

Read this manual thoroughly before operating or servicing this unit.

Warnings, Cautions, and Notices
Safety advisories appear throughout this manual as required. Your personal safety and the proper operation of this machine depend upon the strict observance of these precautions. The three types of advisories are defined as follows:

• WARNING : Indicates a potentially hazardous situation which, if not avoided, could result in death or serious injury.
• CAUTION : Indicates a potentially hazardous situation which, if not avoided, could result in minor or moderate injury. It could also be used to alert against unsafe practices.
• NOTICE : Indicates a situation that could resu lt in equipment or property-damage only accidents.

Important Environmental Concerns
Scientific research has shown that certain man-made chemicals can affect the earth’s naturally occurring stratospheric ozone layer when released to the atmosphere. In particular, several of the identified chemicals that may affect the ozone layer are refrigerants that contain Chlorine, Fluorine and Carbon (CFCs) and those containing Hydrogen, Chlorine, Fluorine and Carbon (HCFCs). Not all refrigerants containing these compounds have the same potential impact to the environment. Trane advocates the responsible handling of all refrigerants-including industry replacements for CFCs and HCFCs such as saturated or unsaturated HFCs and HCFCs.

Important Responsible Refrigerant Practices
Trane believes that responsible refrigerant practices are important to the environment, our customers, and the air conditioning industry. All technicians who handle refrigerants must be certified according to local rules. For the USA, the Federal Clean Air Act (Section 608) sets forth the requirements for handling, reclaiming, recovering and recycling of certain refrigerants and the equipment that is used in these service procedures. In addition, some states or municipalities may have additional requirements that must also be adhered to for responsible management of refrigerants. Know the applicable laws and follow them.

WARNING
Proper Field Wiring and Grounding Required

NOTE : Failure to follow code could result in death or serious injury. All field wiring MUST be performed by qualified personnel. Improperly installed and grounded field wiring poses FIRE and ELECTROCUTION hazards. To avoid these hazards, you MUST follow requirements for field wiring installation and grounding as described in NEC and your local/state/national electrical codes.

Minimum Position Setting
To adjust the minimum position setting and check out the economizer, the power must be connected.

1. Close the unit disconnect and place the zone sensor fan selector in the fan ON position and the heat/cool selector in the OFF position. This will place the damper in the minimum ventilation position.
2. To adjust the minimum position setting for the required ventilation air, use the Symbio™ service and installation mobile app or Symbio™ 700 on-board UI to adjust the economizer minimum position setpoint BAS in the fresh/return air settings menu. The damper will open to this setting each time the blower circuit is energized. When adjusting minimum position, the damper may move to the new setting in several small steps. Once the damper  has remained in position for 10 – 15 seconds without movement, it can be assumed it is at the new position.
3. Replace the filter access panel. The damper will close when the blower circuit is de-energized.
