SAFETY WARNING
Only qualified personnel should install and service the equipment. The installation,
starting up, and servicing of heating, ventilating, and air-conditioning equipment
can be hazardous and requires specific knowledge and training. Improperly
installed, adjusted or altered equipment by an unqualified person could result in
death or serious injury. When working on the equipment, observe all precautions
in the literature and on the tags, stickers, and labels that are attached to the
equipment.

Warnings, Cautions, and Notices
Read this manual thoroughly before operating or servicing this unit. 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.
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 such as HCFCs and HFCs.
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.
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 result in equipment or
property-damage only accidents.
WARNING
Proper Field Wiring and Grounding Required!
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.
WARNING
Personal Protective Equipment (PPE) Required!
Failure to wear proper PPE for the job being undertaken could result in death
or serious injury. Technicians, in order to protect themselves from potential
electrical, mechanical, and chemical hazards, MUST follow precautions in this
manual and on the tags, stickers, and labels, as well as the instructions below:
• Before installing/servicing this unit, technicians MUST put on all PPE
required for the work being undertaken (Examples; cut resistant
gloves/sleeves, butyl gloves, safety glasses, hard hat/bump cap, fall
protection, electrical PPE and arc flash clothing). ALWAYS refer to
appropriate Safety Data Sheets (SDS) and OSHA guidelines for proper PPE.
• When working with or around hazardous chemicals, ALWAYS refer to the
appropriate SDS and OSHA/GHS (Global Harmonized System of
Classification and Labeling of Chemicals) guidelines for information on
allowable personal exposure levels, proper respiratory protection and
handling instructions.
• If there is a risk of energized electrical contact, arc, or flash, technicians
MUST put on all PPE in accordance with OSHA, NFPA 70E, or other country-
specific requirements for arc flash protection, PRIOR to servicing the unit.
NEVER PERFORM ANY SWITCHING, DISCONNECTING, OR VOLTAGE
TESTING WITHOUT PROPER ELECTRICAL PPE AND ARC FLASH
CLOTHING. ENSURE ELECTRICAL METERS AND EQUIPMENT ARE
PROPERLY RATED FOR INTENDED VOLTAGE.

General
Note: An economizer must be installed and functional before attempting to install
a CO2 sensing kit.
These sensors detect and control the carbon dioxide level in the conditioned
space by measuring CO2 concentration, comparing it with a user-adjustable set
point and sending a corresponding control signal to the economizer module.
This causes the economizer damper to be positioned so that sufficient fresh air
is introduced into the conditioned space to reduce and maintain the CO2
concentration to a minimum level as selected by the user.
WARNING
Follow EHS Policies!
Failure to follow instructions below could result in death or serious injury.
• All Trane personnel must follow the company’s Environmental, Health and
Safety (EHS) policies when performing work such as hot work, electrical, fall
protection, lockout/tagout, refrigerant handling, etc. Where local
regulations are more stringent than these policies, those regulations
supersede these policies.
• Non-Trane personnel should always follow local regulations.
Inspection
1. Unpack all components of the kit.
2. Check carefully for shipping damage. If any damage is found, report it
immediately, and file a claim against the transportation company.
3. Visually inspect the components for shipping damage as soon as possible
after delivery, before it is stored. Concealed damage must be reported within
15 days.
4. If concealed damage is discovered, stop unpacking the shipment.
5. Do not remove damaged material from the receiving location. Take photos of
the damage, if possible. The owner must provide reasonable evidence that
the damage did not occur after delivery.
6. Notify the carrier’s terminal of damage immediately by phone and by mail.
Request an immediate joint inspection of the damage by the carrier and the
consignee.
Note: Do not attempt to repair any damaged parts until the parts are inspected
by the carrier’s representative.

WARNING
Hazardous Voltage w/Capacitors!
Failure to disconnect power and discharge capacitors before servicing could
result in death or serious injury.
Disconnect all electric power, including remote disconnects and discharge all
motor start/run capacitors before servicing. Follow proper lockout/ tagout
procedures to ensure the power cannot be inadvertently energized. Verify with a
CAT III or IV voltmeter rated per NFPA 70E that all capacitors have discharged.
CO2 Sensor Operation for Symbio™ 700 with Economizer
Demand Control Ventilation (DCV)
DCV eliminates over-ventilating the space by allowing the fresh air damper to close further than non-CO2 sensing systems, which reduces power consumption. DCV
adjusts the fresh air damper between a DCV Minimum Position and Design Minimum Position. DCV Minimum Position equals non-CO2 sensing systems minimum
damper position - 10%, or more, down to 0% open.
When the CO2 level is greater than or equal to the DCV Minimum CO2 setpoint the supply fan is energized and the fresh air damper modulates between the DCV
Minimum Position Setpoint and the Design Minimum Setpoint, increasing the amount of outdoor air flow and reducing the CO2 level in the space. The damper will only
open up to the Design Minimum Position Setpoint. If the CO2 level drops below the DCV Minimum CO2 Setpoint - 50ppm the fresh air damper will drive to the DCV
Minimum Position. If CO2 level rises above the Building CO2 setpoint the fresh air damper will open to the Design Minimum Position setpoint.
DCV Setup, Damper Position and CO2 Setpoint
Before beginning, turn the fan ON and conduct the Minimum Position Setpoint procedure used WITHOUT CO2 to obtain and record visually the Minimum Position Setpoint
setting and/or the corresponding DC voltage settings for the min and max required to meet ASHRAE standards.
