Important
Environmental Concerns!

Scientific research has shown that certain man-made chemicals can affect the ear th’s naturally
occurring stratospheric ozone layer when released to the atmosphere. In part icular , several of the
identified chemicals that may af fect the ozone layer are refrigerants that contain Chlorine, Fluorine
and Carbon (CFCs) and those containin g 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 re frigerants-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, recovering and recycling of certai n refrigerants and the equipment th at 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.

Ultraviolet (UV) Germicidal Irradiation Lights!

The United States Environmental Protection Agency (EP A) believes that molds and bacteria inside
buildings have the potential to cause health problems in sensitive individuals. If specified, Trane
provides ultraviolet lights (UV -C) as a factory-engineered and installed option in select commercial
air handling products for the purpose of reducin g mi cro bi ol og ical growth (mol d an d 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 prov ided at all unit entry points to
equipment where lights are located.

Warnings, Cautions and Notices

WARNING

Contains Refrigerant!

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 r efrigerant additive s could result in death or serious injury or equi pment dam ag e.

WARNING

Hazard of Explosion!

Use only dry nitrogen with a pressure regulator for pressurizing unit. Do not use acetylene,
oxyg en or compr essed air or mixtur es containing them f or pressu re t esting. Do not use mixtur es
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 tr ace
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.

WARNING

Equipment Damage From Ultraviolet (UV) Lights!

Trane does not r ecommend field installation of ultr aviolet lig hts in its air handlin g equipment f or
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.

WARNING

Personal Protective Equipment (PPE) Required!

Installing/servicing this unit could result in exposure to electrical, mechanical and chemical
hazards.

• Before installing/servicing this unit, technicians MUST put on all Personal Protective
Equipment (PPE) recomm ended f or th e w ork being undertaken. ALWAYS refer to appr opriate
MSDS and OSHA guidelines for proper PPE.

• When working with or around hazardous chemicals, ALWAYS refer to appropriate MSDS and
OSHA guidelines for information on allowable personal exposure levels, proper respiratory
protection and handling recommendations.

• If there is a r isk of arc or flash, technicians MUST put on all Personal Prot ective Equipment (PPE)
in accordance with NFPA70E or other country-specific requirements for arc/flash protection
PRIOR to servicing the unit.

Failure to follow recommendations could result in death or serious injury.

General Information

Operating Environment

The Performance Climate Changer™ air handler is a central station air handler for indoor
applications. When considering the placement of the air handler, it is important to consider the
operating environment. The acc ep t able ambient temperature range for unit operation is -40ºF to
140ºF (-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: Units with UL approval have a maximum ambient temperature requirement of 104ºF. The

customer should provide adequate freeze protectio n for the coils. See “Coil Wint erization”

on page 126 for more information.

Unit Description

The Performance Climate Changer air handler is designed for a variety of controlled-air
applications. The basic unit consists of a fan, heatin g and/or cooling coils, filters, and dampers.

T rane air handlers ship as complete assemblies or in sub-assemblies if shipping splits are required.
Some assembly is required when the unit ships in subassemblies.

A wide variety of components is available for T rane air handlers, including numerous fan, coil, and
filter options, access sections, diffusers, discharge plen ums, face-and-bypass sections, UL­approved electric heat sections, humidifiers, mixing boxes, moisture eliminator sections, exhaust
dampers, controls, blenders and airflow monitoring stations.

Factory-Mounted Controls

Trane air handlers are available with a wide selection of factory-mounted controls, including
controllers, motor starters, and variable frequency drives (VFD).

Most control components are mounted inside the uni t. Depending on the system configuration,
this may include damper actuators, dirty filter switches, averaging temperature sensors, and low
limit switches. VFDs, starters, controllers, control transformers, static pressure transducers, DC
power supplies, and customer interface relays will be in enclosures mounted on the inside of the
unit.

Small items that cannot be factory-mounted, such as space temperature sensors, outside air
temperature sensors, and humidity sensors, will ship inside the control enclosures, or packaged
and shipped inside the fan or mixing box section. Larger items are shipped inside the fan section.

Note: All control valves ship directly to the “ship-to address” from the vendor unless another

address is given on the Trane sales order.

CLCH-SVX07C-EN 9

General Information

All factory-mounted control systems (controls that are factory-wired to a unit controller or
termination strip) ordered without starters or variable-frequency drives (VFDs) are provided with
120 to 24 V ac control transformers mounted and wired in the auxiliary control panel. The customer
must provide 120 Vac control power, 50/60 Hz, typically 3 amps for unit sizes 3 to 57 and 5 amps
for unit sizes 66 to 100. A dedicated 15-amp circuit is recommended.

Factory-mounted control systems ordered with factory-mounted starters or VFDs are supplied with
line to 24 Vac control transformers. No additional power wiring is required.

loose.

Note: T rane will not be responsible for any leak at the field connections. Coils have been factory

pressure tested before shipping.

Assembly Hardware

T rane 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 section. If there is not enough space inside the section, a crate or pallet will
be loaded onto the bed of the truck. Chec k the P arts List on the Field 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

T rane air handlers ship freight-on-board (FOB), meanin g that the unit belongs to the customer the
moment the delivery truck leaves the factory. If damage has occur red to the unit during shipment,
follow these instructions:

Note: Trane is not responsible for shipping da mage.

1 . Make specific notation, describing the damage, on the freight bill. Take photos 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 the Trane sales representative.

4. Keep the damaged material in the same location as it was received.

Note: It is the receiver's responsibility to provide reasonable evidence that concealed damage was

not incurred after delivery.

Storage Recommendations

NOTICE:
Corrosion!

All factory shipping protection should be removed. This wrapping is for transit protection only
and should not be used for jobsite storage.Use only canvas tarps to cover air handlers. Plastic
tarps can cause condensation to form in and on the equipment, which could result in corrosion
damage or wet storage stains.

Indoor air handlers and/or field-installed accessories that must be stored for a period of time before
installation must be protected from the elements. A controlled indoor environment is
recommended for proper storage.

Outdoor air handlers require no specia l protection for storage before installation. Keep the
equipment in the original container for protection and ease of handling.

Note: The warranty does not cover damage to the unit or controls due to negligence during

storage.

12 CLCH-SVX07C-EN

General Storage

The unit controller and all other electrical/electroni c components should be stored in conditions of

-20ºF to 120°F and 5 to 95 percent relative humidity, non-condensing. Electrical components are

not moisture-tolerant. Factory protective coverings should be removed prior to storage.

Long-Term Storage

For longer periods of storage, allow proper clearance around the unit to perform periodic
inspection and maintenance of the equipment.

While the unit is in storage:

• Every two weeks, rotate the fan and motor shaft 30 revolutions by hand. Chec k for free rotation.

• Every six months, chec k fan shaft bearings and grease lines. Add grease using a manual grease
gun following the lubrications recommendations in “Fan Bearing Lubrication” on page 123.

• Check the motor lubrication; remove and clean grease plugs and check for the presence of
moisture in the grease. If moisture is present, remove the motor and send it to an authorized
repair shop for bearing inspection/replacement. If no moisture if present, refer to the motor
manufacturer’s lubrication reco mm end ati on for proper lu bricatio n.

Outdoor Storage Considerations

Outdoor storage is not recommended for units that will be installed indoors. However, when
outdoor storage is necessary, several things must be done to prevent damage :

Note: Keep the equipment on the o riginal wooden blocks/skid fo r protection and ease of handling.

• Select a well-drained area, preferably a concrete pad or blacktop surface.

• Place the unit on a dry surface or raised off the ground to assure adequate air circulation
beneath the unit and to assure no portion of the unit will contact standing water at any time.

• Loosen the belt tension on the drive belts.

• Cover the unit securely with a canvas tarp.

• Do not stack units.

• Do not pile other material on the unit.

Pre-Installation Requirements

Preparing the Unit Site

• Ensure the installation site can support the total weight of the unit (see “Unit Dimensions and

Weights” on page 16 for approximate section weights; refer to the unit submittals for actual

weights).

• Allow sufficient space for adequate free air and necessary service access (see “Service

Clearances” on page 16). Refer to submittals for specific minimums.

• Allow room for supply and return piping, ductwork, electrical connections, and coil removal.

• Ensure there is adequate height for condensate drain requirements. See “Drain Pan T rappi ng”

on page 80.

Note: If unit is installed in a mechanical room on a pad, inadequate height may necessitate core-

drilling the floor to attain proper trap height. Insufficient height could inhibit condensate
drainage and result in flooding the unit and/or equipment room.

CLCH-SVX07C-EN 13

Pre-Installation Requirements

NOTICE:

Microbial Growth!

The floor or foundation must be level and the condensate drain at the proper heig ht for proper
coil drainage and condensate flow. Standing water and wet surfaces inside the equipment can
become an amplification site for microbial growth (mold), which may cause odors and damage
to the equipment and building materials.

• Confirm the roof curb or foundation of the mounting platform is level and large enough to
accommodate the unit. Refer to the unit submittals for specific dimensions.

• Provide adequate lighting for maintenance personnel to perform maintenance duties.

• Provide permanent power outlets in close proximity to the unit for installation and
maintenance.

• Depending upon job requirements, the customer may n eed to provide 120 V ac power to the unit
controller. Refer to submittals for more information. A dedicated 15-amp circuit is
recommended.

• Wiring for the air handler must be provided by the installer and must com ply with all national
and local electrical codes.

• If the unit integral base frame ceiling suspension provisions are not used, the installer/
contractor must provide a ceiling-susp ended mounting frame desig ned to support the length,
width, and weight of the entire air-handling unit. See “Ceiling Suspension for Indoor Air

Handlers Sizes 3-57” on page 30 for more information.

• Rooftop curb-mount ed units m ust be sealed tightly to the curb. Use proper sealants and roof­to-curb sealing techniques to prevent water and air leakage. Refer to CLCH-SVN05A-EN Roof
Curbs for Performance Climate Changer™ Air Handlers Installation Instructions.

Note: Preparation of the roof curb or pier mount and roof openings should be completed prior to

lifting the unit to the roof.

Roof Curb Installation Checklist

See CLCH-SVN05A-EN Roof Curbs for Performance Climate Changer™ Air Handlers Installation
Instructions for information on installing roof curbs.

It is recommended that the curb be installed directly on the support members and fastened to the
supports using tack welds or other equivalent methods. Properly supported decking should be
installed inside the air handler section of the curb when this method is used. See Figure 2.

Figure 4. Isolator tie-down removal for unit sizes 35-120

Prior to unit placement, remove the shipping tie-downs per the following instructions:

• Shipping tie-downs are located at each corner of the isolation base. See Figure 51, Figure 52,

Figure 53 and Figure 54.

• Access for removal of shipping tie-downs for unit sizes 3-30 is available through th e fan section
access door or opposite drive-side plug panel. See Figure 5.

• Remove the bolt. This will release the isolator and make it possible to remove the pipe or spacer .

• Replace plug panel if applicable.

Note: For outdoor air handlers, after isolator tie-down is removed, remove the paper backing from

the butyl tape around plug panel perimeter prior to replacing plug panel.

General Lifting Considerations

 WARNING

Heavy Objects!

Always place, assemble, and suspend sections/subassemblies one at a time. Do not lift units in
windy conditions. Do not raise units o verhead with personnel below unit. F ailu r e to foll ow th ese
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 r eady to set. Do not mo ve unit or su bassembly without the skid in
place as shipped from the factory. Premature skid removal could 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 pro vided in “Unit Dimensions

and Weights” on page 16. Refer to the unit submit tals for actual section weights. Test the unit for

proper balance before lifting.
For outdoor air handlers, preparation of the roof curb or pier mount and roof openings must be

completed before lifting to the roof. S e e CLCH-SVN04A-EN Roof Curbs for Performance Climate
Changer Air Handlers installation instructions for details.

CLCH-SVX07C-EN 25

Installation - Mechanical

Rigging and spreader
bars furnished
by others

 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 suppor ting the enti r e w eight 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.

Always rig subassemblies or sections as they ship from the factory. Never bolt sections together
before rigging.

• Make the loop of the sling parallel to the direction of airflow, if possible.

• When hoisting the unit into position, use the proper rigging method, such as straps, slings,
spreader bars, or lifting lugs for protection and safety. Use all lifting lugs provided.

• For unit sizes 3 to 120 with integral base frame, use field-provided spreader bars and slings to
rig units and subassemblies as shown in Figure 6. The air handler is not designed to be lifted
or rigged from the top of the unit.
