Warnings, Cautions and Notices
Warnings, Cautions and Notices. Note that warnings, cautions and notices appear at
appropriate intervals throughout this manual. Warnings are provide to alert installing contractors
to potential hazards that could result in personal injury or death. Cautions are designed to alert
personnel to hazardous situations that could result in personal injury, while notices indicate a
situation that may result in equipment or property-damage-only accidents.
Your personal safety and the proper operation ofthis 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
identifiedchemicalsthatmay affecttheozonelayerarerefrigerantsthatcontainChlorine, Fluorine
andCarbon(CFCs)andthosecontainingHydrogen,Chlorine,FluorineandCarbon(HCFCs).Notall
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.
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. The Federal Clean Air Act (Section 608) sets forth the requirements for handling,
reclaiming,recoveringandrecyclingofcertainrefrigerantsandtheequipmentthatisusedinthese
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
Refrigerant warning information!
System contains oil and refrigerant under high pressure. Recover refrigerant to relieve pressure
before opening the system. See unit nameplate for refrigerant type. Do not use non-approved
refrigerants, refrigerant substitutes, or refrigerant additives.
Failure to follow proper procedures or the use of non-approved refrigerants, refrigerant
substitutes, or refrigerant additives could result in death or serious injury or equipment damage.
ATTENTION: Warnings, Cautions and Notices appear at appropriate sections throughout
this literature. Read these carefully.
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 may result in equipment or property-damage only
accidents.

Warnings, Cautions and Notices
WARNING
Hazard of Explosion!
Use only dry nitrogen with a pressure regulator for pressurizing unit. Do not use acetylene,
oxygen or compressed air or mixtures containing them for pressure testing. Do not use mixtures
of a hydrogen containing refrigerant and air above atmospheric pressure for pressure testing as
they may become flammable and could result in an explosion. Refrigerant, when used as a trace
gas should only be mixed with dry nitrogen for pressurizing units. Failure to follow these
recommendations could result in death or serious injury or equipment or property-only damage.
Ultraviolet (UV) Germicidal Irradiation Lights
The United States Environmental Protection Agency (EPA) believes that molds and bacteria inside
buildings have the potential to cause health problems in sensitive individuals. If specified, Trane
providesultraviolet lights(UV-C)asafactory-engineeredandinstalledoption inselect commercial
air handling products for the purpose of reducing microbiological growth (mold and bacteria)
within the equipment. When factory provided, polymer materials that are susceptible to
deterioration by the UV-C light will be substituted or shielded from direct exposure to the light. In
addition, UV-C radiation can damage human tissue, namely eyes and skin. To reduce the potential
for inadvertent exposure to the lights by operating and maintenance personnel, electrical
interlocks that automatically disconnect power to the lights are provided at all unit entry points to
equipment where lights are located.
 WARNING
Equipment Damage From Ultraviolet (UV) Lights!
Trane does not recommend field-installation of ultraviolet lights in its air handling equipment for
the intended purpose of improving indoor air quality. High intensity
C-band ultraviolet light is known to severely damage polymer (plastic) materials and poses a
personal safety risk to anyone exposed to the light without proper personal protective
equipment (could cause damage to eyes and skin). Polymer materials commonly found in HVAC
equipment that may be susceptible include insulation on electrical wiring, fan belts, thermal
insulation, various fasteners and bushings. Degradation of these materials can result in serious
damage to the equipment.
Trane accepts no responsibility for the performance or operation of our air handling equipment
in which ultraviolet devices were installed outside of the Trane factory.

General Information
Operating Environment
When considering the placement of the air handler, it is important to consider the operating
environment.The acceptable ambienttemperaturerange for unitoperationis -40ºF to140ºF(-40ºC
to 60ºC).
For heating applications, a special motor may be required to withstand the higher temperatures.
Motors with Class B insulation are acceptable for ambient temperatures up to 104º F, while motors
with Class F insulation can withstand ambient temperatures to +140º F (60º C).
Note: The customer should provide adequate freeze protection for the coils. See the “Coil
Winterization” section on page 89 for more information.
Unit Description
The M-Series Climate Changer™ air handler is a highly flexible, customizable, cataloged air
handlerthatcanmeetmostcommercial,industrialandinstitutionalapplications.Withitsmodular,
“building-block” construction, the M-Series air handler can be tailored to meet specific job
requirements for new or existing buildings. A wide range of standard and custom-engineered
modules can be arranged and stacked in any number of configurations to address application and
space requirements.
The wide array of available components is key to fine-tuning the performance of the M-Series air
handler. The broad spectrum of fan coil, filter and control options allows you to optimize the
performance and efficiency of your air handler.
While several air-handling manufacturers offer some custom features, most find it difficult to
incorporate those features into their standard cataloged unit, which leads to increased costs and
extendedleadtimes.Tranehasengineered manycustomsolutions-with testedperformance data
- for the M-Series air handler, without the cost and lead times associated with full-blown custom
units.
Trane continues to develop new options for M-Series air handlers, so that you remain firmly in
control of performance and cost on every design project.

Pre-Installation Requirements
M-SeriesClimate Changer airhandlers canshipas individualmodules,modulesubassemblies,or
a complete air handler. Unit sizes 3 to 57 may have a base rail (also called an external support kit).
Unit sizes 66 to 120 ship on an integral base rail. Modules shipped without a base rail are securely
fastened to a wooden skid using 4-inch mounting legs for ease of handling. No skid is provided on
units with base rails. Trane recommends leaving units and accessories, such as filter boxes and
control devices, in their shipping packages/skids for protection and ease of handling until
installation.
M-Series air handler sizes 3 to 57 ship in subassemblies if the total length of the unit exceeds
98 inches,orifthetotalweightexceedsthelimitsascalculatedusingTables2-5onpages14-17and
Table 7 on page 18. If an optional factory base rail and standard factory shipping splits were
ordered, each subassembly will ship on its own base rail as standard. If an optional factory base
rail and minimum factory shipping splits were ordered, the base rail will ship separate from each
subassembly.
M-Series air handler sizes 66 to 120 ship in subassemblies if the total length of the unit exceeds
102 inches, or if the total weight exceeds 4,300 pounds. These unit sizes have an integral base rail
on each module.
Receiving Checklist
Upon receipt of the air-handling unit, prior to unloading, visually check the components for any
damage that may have occurred during shipment. Conduct a thorough inspection immediately
before accepting the shipment.
Note: Delivery cannot be refused. Trane is not responsible for shipping damage.
1. Remove any shrink wrap material that may have been used during shipping. Cut all banding
loose from the skids (if applicable). Do not remove the unit from the skid.
NOTICE
Equipment Damage!
Keep skid in place until unit is ready to set. Do not move the unit or subassembly without the
skid in place as shipped from the factory. Premature skid removal may result in equipment
damage.
2. Check all access doors to confirm the latches and hinges are not damaged.
3. Inspect the interior of each module for any internal damage.
Note: Concealed damage must be reported within 15 days of receipt.
4. Inspect the coils for damage to the fin surface and/or coil connections.
5. If the unit was ordered with factory-mounted controls, locate all sensors.
Note: Items that cannot be factory-mounted should ship inside the control enclosures or should
be packaged inside the fan module or mixing box module.
6. Check all control devices attached to the unit exterior and confirm they are not damaged.
7. Manually rotate the fan wheel to ensure free movement of the shaft, bearings, and drive.
8. Inspect the fan housing for any foreign objects.

Pre-Installation Requirements
Assembly Hardware
Trane air handlers ship with all necessary assembly hardware and gasket material. This hardware
is packaged in either a clear plastic envelope or cardboard box and can be found inside the fan,
mixing box, or access module. If there is not enough space inside the module, a crate or pallet will
beloadedonto the bedof the truck. Checkthe Parts Liston theField Assembly drawing against the
contents of the crate. Do not proceed with unit assembly until verification that all materials are
present. Sometimes it is necessary to use more than one section to ship hardware. Please check
all sections thoroughly before contacting your local Trane sales engineer to report missing
hardware.
Resolving Shipping Damage
Trane air handlers ship free on board (FOB) ship dock, meaning that the unit belongs to the
customer the moment the delivery truck leaves the factory shipping dock. If damage has occurred
to the unit during shipment, follow these instructions:
Note: Trane is not responsible for shipping damage.
1. Make specificnotation,describing the damage,on the freightbill.Takephotos of the damaged
material, if possible.
2. Report all claims of shipping damage to the delivering carrier immediately and coordinate
carrier inspection, if necessary.
Note: : Do not attempt to repair the unit without consulting the delivering carrier.
3. Notify your Trane sales representative of the damage and arrange for repair.
Note: Do not attempt to repair the unit without consulting your Trane sales representative.
4. Keep the damaged material in the same location as it was received.
Note: Itisthereceiver'sresponsibilitytoprovidereasonableevidencethatconcealeddamagewas
not incurred after delivery.
Job Site Storage Recommendations
M-Series units and/or field-installed accessories that must be stored for a period of time before
installations must be protected from the elements. A controlled indoor environment is
recommended for proper storage.
Note: The warranty does not cover damage to the unit or controls due to negligence during
storage.
General Storage
Theunitcontrollerand all other electrical/electroniccomponentsshouldbestoredinconditionsof
-20ºF to 120°F and 5 to 95 percent relative humidity, non-condensing. Electrical components are
not moisture-tolerant. Factory protective coverings, such as shrink-wrap material, should be
removed within 48 hours of receiving the unit, and prior to storage.

Lifting and Rigging
WARNING
Heavy Objects!
Do not use cables (chains or slings) except as shown. Each of the cables (chains or slings) used
to lift the unit must be capable of supporting the entire weight of the unit. Lifting cables (chains
or slings) may not be of the same length. Adjust as necessary for even unit lift. Other lifting
arrangements may cause equipment or property-only damage. Failure to properly lift unit could
result in death or serious injury.
 WARNING
Heavy Objects!
Always place, assemble, and suspend modules/subassemblies one at a time. Do not lift units in
windy conditions. Do not raise units overhead wit personnel below unit. Failure to follow these
instructions could result in death, serious injury, or equipment damage.
 WARNING
Improper Unit Lift!
Test lift unit approximately 24 inches to verify proper center of gravity lift point. To avoid
dropping of unit, reposition lifting point if unit is not level. Failure to properly lift unit could
result in death or serious injury or possible equipment or property-only damage.
NOTICE
Equipment Damage!
Keep skid in place until unit is ready to set. Do not move unit or subassembly without the skid in
place as shipped from the factory. Premature skid removal may result in equipment damage.
Before preparing the unit for lifting, estimate the approximate center of gravity for lifting safety.
Because of placement of internal components, the unit weight may be unevenly distributed, with
more weight in the coil and fan areas. Approximate unit weights are provided in the “Dimensions
and Weights” section on page 13. Refer to the unit submittals for actual module weights. Test the
unit for proper balance before lifting.
When hoisting the unit into position, use the proper rigging method, such as straps, slings,
spreader bars, or lifting lugs for protection and safety.
• For unit sizes 3 to 57 without base rails, use spreader bars and slings to rig units and
subassemblies as shown in Figure 2.
• Forunitsizes3to57withbaserails,usespreaderbarsandslingstorigunitsandsubassemblies
as shown in Figure 3.
• For unit sizes 66 to 120, use spreader bars in conjunction with shackles attachedat the base rail
lifting lugs to rig units or subassemblies as shown in Figure 4.
