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 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 Labelling 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.

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.
NOTICE
Equipment Damage!
Proper adjustment of the fan belt is important to ensure optimal unit operation.
Over tightening or under tightening the fan belt can result in belt slippage and
excessive wear, bearing damage, sheave misalignment, and possible failure of fan
motor mounts.
7. Check the alignment between the fan and motor sheaves using a straight
edge. Adjust as necessary. Torque the fan and motor sheave set screws to
126 to 165 inch pounds (14.2 to 18.6 N-m).
8. Torque the motor securing bolts to 144 to 151 inch pounds (16.3 to 17.1 N-m).
9. Adjust the tension of the fan belt. The correct operating tension for a V-belt fan
drive is the lowest tension at which the belt will not slip under peak load
conditions. The locknut should be tightened sufficiently to ensure that the
motor plate assembly maintains the desired belt tension.
Note: The new V-belts tend to stretch after having been placed in operation.
Periodically check the tension of the belt.
