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 thismanual thoroughly before operating orservicing this unit. Safety
advisories appear throughout this manual as required. Your personal safety
and the proper operation of this machine depend uponthe strict observance
of these precautions.
The three types of advisories are defined as follows:
WARNING
CAUTION
NOTICE
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 allrefrigerants containing these compounds havethe
same potential impactto theenvironment. Traneadvocates 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.

Proper Field Wiring and Grounding Required!
Failure to follow code could result in death or serious injury. All field wiring
MUST be performedby qualified personnel. Improperlyinstalled and grounded
field wiring poses FIREand ELECTROCUTION hazards. To avoid these hazards,
you MUST follow requirements for field wiring installation and grounding as
described in NEC and your local/state electrical codes.
Personal Protective Equipment (PPE) Required!
Failure to wearproper PPE for thejob being undertaken couldresult 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 DataSheets (SDS) and OSHAguidelines for proper PPE.
• When working with or around hazardouschemicals, 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, orflash, 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.

Follow EHS Policies!
Failure to follow instructions below could result in death or serious injury.
• All Trane personnelmust follow the company’sEnvironmental, Health and
Safety (EHS)policies whenperforming worksuch ashot 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.

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 ensurethe power cannot beinadvertently energized. Verify with
a CATIII or IV voltmeterrated per NFPA 70Ethat all capacitors havedischarged.

8. Proceed to “Minimum Position Setting”.
Minimum Position Setting
Live Electrical Components!
Failure to followall electrical safety precautionswhen exposed to liveelectrical
components could result in death or serious injury.
When it is necessary to work with live electrical components, have a qualified
licensed electrician or
handling live electrical components perform these tasks.
To adjust the minimum position setting and check out the damper, 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/coolselector 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,
turn the potentiometer (on the damper motor) clockwise to “open” (to
increase the amount of ventilation) or counterclockwise to “close” (to
decrease theamount of ventilation). Thedamper will open tothis setting
each time the blower circuit is energized.
3. When adjusting minimum position, the damper may move to the new
setting
in severalsmall steps. Once thedamper has remained in position
for 10- 15 seconds without movement,it can be assumed itis at the new
position.
4. Replace the filter access panel. The damper will close when the blower
circuit
is de-energized.
