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 death or personal injury. Cautions are designed to alert

personnel to hazardous situations that could result in

personal injury, while notices indicate a situation that

could result in equipment or property-damage-only

accidents.

Your personal safety and the proper operation of this

machine depend upon the strict observance of these

precautions.

Read this manual thoroughly before operating or servicing

this unit.

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.

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 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.

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

sIndicates 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

WARNING

Proper Field Wiring and Grounding

Required!

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 electrical codes. Failure to

follow code could result in death or serious injury.

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)

recommended for the work being undertaken.

ALWAYS refer to appropriate MSDS sheets and OSHA

guidelines for proper PPE.

• When working with or around hazardous chemicals,

ALWAYS refer to the appropriate MSDS sheets and

OSHA guidelines for information on allowable

personal exposure levels, proper respiratory

protection and handling recommendations.

• If there is a risk of arc or flash, technicians MUST put

on all Personal Protective Equipment (PPE) in

accordance with NFPA 70E 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.

Warnings, Cautions and Notices

CLCH-SVX07C-EN 3

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 provides ultraviolet lights

(UV-C) as a factory-engineered and installed option in

select 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

The Performance Climate Changer™ air handler is a

central station air handler for indoor and outdoor

applications. When considering the placement of the air

handler, it is important to consider the operating

environment. The acceptable 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 protection for the

coils. See “Routine Maintenance” on page 121 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, heating and/or cooling coils, filters, and

dampers.

Trane 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 Trane air

handlers, including numerous fan, coil, and filter options,

access sections, diffusers, discharge plenums, face-and-

bypass sections, UL-approved 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 unit.

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.

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 Vac 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.

Pre-Packaged Solutions for Controls

If the air handler has been selected using one of Trane’s

pre-packaged solutions options for controls, there are a

number of resources available to aid in commissioning

and start-up of the unit. These resources include

commissioning sheets, graphics and technical application

notes. The technical application notes include the control

sequencing, Trane Graphic Programming (TGP) and Rover

set-up files for the specific unit selected. These resources

are available through your local Trane sales office.

General Information

8 CLCH-SVX07C-EN

For a more in-depth understanding of controls, refer to the

following manuals:

• For programmable MP580 controllers

–CNT-SVP01A-EN

• For hardware installation

–CNT-SVN01A-EN

• For Trane TR200 Drives

–BAS-SVX19A-EN

Wiring

Entrances are generally provided for field-installation of

high and low voltage wiring through a pipe/nipple

connection in the unit depending on unit configuration

with or without factory-mounted controls. Before

installation, consider overall unit serviceability and

accessibility before mounting, running wires (power),

making penetrations, or mounting any components to the

cabinet.

Wiring to the air handler must be provided by the installer

and must comply with all national and local codes. The fan

motor nameplate includes a wiring diagram. If there are

any questions concerning the wiring of the motor, write

down the information on the motor nameplate and contact

your local Trane sales office.

WARNING

Proper Field Wiring and Grounding

Required!

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 electrical codes. Failure to

follow code could result in death or serious injury.

CLCH-SVX07C-EN 9

Pre-Installation Requirements

Based on customer requirements, Trane air handlers can

ship as complete units or as individual sections to be field

assembled. Unit sizes 3-120 have an integral base frame

designed with the necessary number of lift points for safe

installation. Indoor air handlers sizes 3-30 are also shipped

with a shipping skid designed for forklift transport.

Unless otherwise specified, Performance indoor air

handlers ship in subassemblies if the total length of the

units exceeds 98 inches or if the total weight exceeds the

limits shown in Table 1. If either the maximum weight or

maximum length is exceeded, the unit will ship in multiple

pieces. See Table 2 for limits for outdoor air handlers.

Note: These limits are based on a four-point lift.

Receiving Checklist

Upon receipt of the air handler(s), a thorough inspection

should be performed to note any shipping damage that

may have occurred and that the shipment is complete. All

factory shipping protection should be removed

immediately to allow complete access for the inspection.

The shipping protection provided by the factory is for

transit protection only and should not be used as a jobsite

storage cover.

Note: Delivery cannot be refused. Trane is not

responsible for shipping damage.

• Check all access doors to confirm that the latches and

hinges are not damaged.

• Inspect the interior of each section for any internal

damage.

Note: Concealed damage must be reported within

15 days of receipt.

• Inspect the coils for damage to the fin surface and/or

coil connections.

• 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 or mixing box section.

• Check all control devices attached to the unit exterior

and confirm that they are not damaged.

• Manually rotate the fan wheel to ensure free

movement of the shaft, bearings, and drive.

• Inspect the fan housing for any foreign objects.

• If the unit is shipped in subassemblies, locate the

assembly hardware, which should be packaged and

shipped inside the fan or mixing box section.

• Inspect and test all piping for possible shipping

damage. Nipples may be installed on coils at the

factory but should always be tightened and tested

before any connections are made. Rough handling

during shipping, in addition to other factors can cause

pipe connections to become loose.

Note: Trane will not be responsible for any leak at the field

connections. Coils have been factory pressure

tested before shipping.

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 section. If

there is not enough space inside the section, a crate or

pallet will be loaded onto the bed of the truck. Check the

Parts 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

Trane air handlers ship freight-on-board (FOB), meaning

that the unit belongs to the customer the moment the

delivery truck leaves the factory. If damage has occurred to

the unit during shipment, follow these instructions:

Note: Trane is not responsible for shipping damage.

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.

This wrapping is for transit protection only and

should not be used for jobsite storage.

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 special 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.

General Storage

The unit controller and all other electrical/electronic

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. Check for free rotation.

• Every six months, check fan shaft bearings and grease

lines. Add grease using a manual grease gun following

the lubrications recommendations in “Fan Bearing

Lubrication” on page 124.

• 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

recommendation for proper lubrication.

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 original wooden blocks/

skid for 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.

Preparing the Unit Site

• Ensure the installation site can support the total weight

of the unit (see “Unit Dimensions and Weights” on

page 12 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 12). 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 Trapping” on page 86.

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.

NOTICE:

Corrosion!

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.

Pre-Installation Requirements

CLCH-SVX07C-EN 11

• 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

need to provide 120 Vac 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 comply 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-suspended mounting frame

designed to support the length, width, and weight of

the entire air-handling unit. See “Ceiling Suspension”

on page 26 for more information.

• Rooftop curb-mounted units must be sealed tightly to

the curb. Use proper sealants and roof-to-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.

1. Verify that the roof structure can adequately support

the combined weight of the unit and curb assembly.

2. Ensure that the selected installation location provides

sufficient service and operational clearances.

3. Remove any twist within the curb due to roof supports

and square the curb.

4. Level the curb.

5. Secure the curb to the roof support members.

6. Install 2-inch thick boards or rigid insulation around the

curb.

7. Install cant strips around the curb.

8. Bring field supplied roofing felt up to the top of the curb

nailing strips. Nail felt into place.

9. Install field supplied flashing under the lip of the curb

flanges and over the felt.

10. Apply sealant to the four corners.

11. Caulk all joints between the curb and the roof.

Attach the gasket material to the curb’s top flanges (entire

perimeter) and to the supply and return air duct opening

panel flanges.

NOTICE:

Microbial Growth!

The floor or foundation must be level and the

condensate drain at the proper height 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

could cause odors and damage to the equipment and

building materials.

Unit Dimensions and Weights

Service Clearances

A minimum clearance of the section width plus 12 inches

on the access door side of the gas heat section is

recommended for routine maintenance. This clearance

provides enough room to replace the heat exchanger in

the event of failure. The section side panels must be

removed to access the heat exchanger. Refer to Table 3 for

service clearance recommendations for the air handler.

Note: For specific dimensional and weight information, refer to the unit submittals. The dimensions and weights in this

General Lifting Considerations

:

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 “Unit

Dimensions and Weights” on page 12. Refer to the unit

submittals 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. See CLCH-SVN04A-EN Roof Curbs for

Performance Climate Changer Air Handlers installation

instructions for details.

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. See Figure 10 and Table 8

for lug hole sizes and location.

Figure 9. Plug panel plate

WARNING

Risk of Unit Dropping!

Always place, assemble, and suspend modules/

subassemblies one at a time. Placing, assembling, and/

or suspending more than one module/subassembly at

a time could result in module/subassemblies dropping

and crushing technicians which 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 unit dropping and

possibly crushing operator/technician which could

result in death or serious injury and possible equipment

or property-only damage.

Remove plug panel plate

Remove

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 could result in equipment damage.

WARNING

Heavy Objects!

Ensure that all the lifting equipment used is properly

rated for the weight of the unit being lifted. Each of the

cables (chains or slings), hooks, and shackles 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 could cause

equipment or property damage. Failure to follow

instructions above or properly lift unit could result in

unit dropping and possibly crushing operator/

technician which could result in death or serious injury.

Installation - Mechanical

CLCH-SVX07C-EN 23

• 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 11. The air handler

is not designed to be lifted or rigged from the top of the

unit.

• For outdoor units, never stack the pipe cabinet or inlet

hood on the unit as it is being lifted.

• Do not attach the intake/exhaust hood or pipe cabinet

to the unit prior to lifting the unit. Doing so may

damage the equipment. Attach the hoods to the unit

only after all sections are in place.

• For outdoor air handlers, all shipping supports and

crating on the face of the sections must be removed to

permit proper fit-up and sealing of the surfaces.

Dispose of properly.

Forklifting Considerations

Note: Do not use a forklift on outdoor air handlers or

indoor air handlers/subassemblies larger than size

30.

For unit sizes 3-30, a forklift may be used to lift a single

section or small subassembly, provided the forks extend

under both ends of the base frame, or as indicated in

Figure 14. The forks should not contact the bottom of the

air handler. Units should only be lifted from the proper end

identified by the lifting label on the unit. A lifting crane or

other means should be used for larger units where forks

cannot extend under both base rails.

WARNING

Risk of Unit Dropping!

Always place, assemble, and suspend modules/subassemblies one at a time. Placing, assembling, and/or suspending

more than one module/subassembly at a time could result in module/subassemblies dropping and crushing

technicians which could result in death, serious injury, or equipment damage.

Unit Placement and Assembly

If the air handler ships in subassemblies or in individual

sections, some assembly is required, including:

• Ceiling-suspended indoor unit assembly; see See

“Ceiling Suspension” on page 26.

• Section-to-section assembly; see “Section-to-Section

Assembly” on page 27.

:

Unit Placement

If a unit arrives in sections, then each section must be

individually hoisted, set on the housekeeping pad, roof

curb, or pier mount and then assembled.

Refer to the unit submittals and unit tagging for correct

placement of all sections. If there are any discrepancies

between the submittals and the unit tagging, contact your

local Trane representative before proceeding.

Following the order of the sections on the unit submittals

and tagging, individually place each unassembled section

or subassembly in the appropriate installation location.

Note: Prior to placing fan section in the appropriate

installation location, verify shipping tie-downs

have been removed.

For outdoor units, the pipe cabinet must also be mounted

as an individual section. Refer to “Pipe Cabinet

Installation” on page 32 for specific instructions.

When mounting the unit on a roof curb, make sure the

gasketing between the roof curb and unit base provides an

airtight seal.

When mounting the unit on a pier mount, locate one pier

at each corner as a minimum, directly underneath any

shipping split (ensure full support under each side) and

then every four feet at equally spaced intervals around the

perimeter of the unit. Both the unit and the pipe cabinet

should be supported by their base around the entire

perimeter. See Figure 15 and Figure 16.

WARNING

Toxic Fumes!

Keep open flame away from unit exterior or interior. Do

not weld or use cutting torch on the exterior or interior

of the unit. The unit contains polyurethane insulation.

Flame could produce toxic gas which could result in

death or serious injury.

NOTICE:

Equipment Damage!

The internal sections of this unit containing electrical

components must not exceed 104o F operating

temperature. Internal sections of the unit which do not

contain electrical components must not exceed 200o F

temperature. Failure to comply with temperature

requirements could result in equipment damage.

WARNING

Risk of Unit Dropping!

Always place, assemble, and suspend modules/

subassemblies one at a time. Placing, assembling, and/

or suspending more than one module/subassembly at

a time could result in module/subassemblies dropping

and crushing technicians which could result in death,

serious injury, or equipment damage.

NOTICE:

Microbial Growth!

The floor or foundation must be level and the

condensate drain at the proper height 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

could cause odors and damage to the equipment and

building materials.

Figure 15. Piers located in each corner and spaced evenly

every four feet

Note: Piers beneath shipping splits must be structurally

sound to support the weight of the unit.

Piers

Installation - Mechanical

26 CLCH-SVX07C-EN

For proper operation, the unit must be installed level (zero

tolerance) in both horizontal axes. For vertical discharge

units, allow space under the unit for supply air ductwork

connections.

Unit Assembly

Note: Air handlers often include optional factory-

provided casing penetration entry points for field-

provided wiring. Consider overall unit

serviceability and accessibility before mounting,

running wires (power), making cabinet

penetrations, or mounting any components to the

cabinet.

See “Component Installation Requirements” on page 45

for special assembly/installation considerations.

Removing the Shipping Skid

Remove the wooden shipping blocks, wooden toe cleat if

there is one, and end cleats prior to lowering unit into final

position or installing the unit to the roof curb.

Ceiling Suspension

Note: Ceiling suspension is not recommended for units

larger than size 57 unless using a field-provided

mounting frame.

Using a Field-Provided Mounting Frame

If a field-provided mounting frame is used for ceiling

suspension, the installer/contractor must provide a

ceiling-suspended mounting frame designed to support

the length, width, and weight of the entire air-handling

unit. See “Unit Dimensions and Weights” on page 12 for

approximate weights.

Note: It is the building engineer’s responsibility to size the

structural channels and to provide the appropriate

hangers.

Structural channels in a field-provided frame can be

mounted parallel to airflow or perpendicular to airflow:

• For parallel-to-airflow channels, size channels based

on a four-point load distribution (see Figure 17.

• For perpendicular-to-airflow channels, size channels

based on the load distribution of the individual

sections and install the channels so that both ends of

every section are supported (see Figure 18).

Figure 16. Side view with two shipping splits - locate

one pier directly under each shipping split

Note: Piers beneath shipping splits must be structurally

sound to support the weight of the unit.

WARNING

Risk of Unit Dropping!

Do not use mounting legs for ceiling suspension,

external isolation, or unit support during module

placement. Mounting legs are designed only to secure

the unit to the floor, housekeeping pad, or platform.

Improper use of the mounting legs as described above

could result in unit dropping and crushing technicians

which could result in death or serious injury, and

equipment damage.

CLCH-SVX07C-EN 27

Using Integral Base Frame

If using the factory-provided integral base frame for ceiling

suspension, individual sections and/or subassemblies will

have base frame shipping splits and base frame lifting

lugs. When using the base frame for ceiling suspension:

• Suspend the unit (on both sides of the unit) at each

shipping split lug as well as the four corners of the unit

(see Figure 19). See Figure 10 and Table 8 on page 23

for lug hole sizes.

• Bolt shipping splits together.

The hanger rods must extend through the bottom of the

base lug. It is the building engineer’s responsibility to

provide the appropriate hangers.

Shipping Gussets

Prior to pulling the shipping splits together, the shipping

gussets (see Figure 20) should be removed to simplify

panel removal (except for units required OSHPD

certification). If there is enough access after joining the

shipping splits, the gussets can be removed after they are

joined. The exception to this rule is for size 35-50 stacked

units. For these sizes, the gusset should be left in place for

the lower level unit unless they are installed in a shipping

split that contains a coil.

Do not mistake the coil structural gusset (see Figure 21)

used on unit sizes 66-120 with the shipping gussets.

Section-to-Section Assembly

Air handlers ship with all necessary assembly hardware

and gasket material. The hardware should be packaged in

either a clear plastic envelope or cardboard box inside the

fan section, access section, or mixing box.

The number of sections to be assembled often makes it

necessary to use more than one section to ship the

assembly material; therefore, check all sections

thoroughly before contacting your Trane sales

representative to report missing items.

Sections are joined with gasketing applied to one of the

mating surfaces and hardware to bolt the sections

together. The gasketing for section-to-section joints is a

closed cell foam with adhesive backing.

To assemble the unit:

1. Locate the mounting hardware and gasket material.

2. All shipping supports and crating on the face of the

sections must be removed and discarded to permit

proper fit-up and sealing of the surfaces. Remove any

shipping bolts located on the mounting surfaces of the

sections (see Figure 22).

3. Apply the gasketing to one of the mating surfaces; see

Figure 22, Figure 23, and Figure 24.

4. If the unit is equipped with factory-mounted controls,

move adjacent subassembly within six inches and

fasten quick connects where the sections bolt together

(see Figure 25).

Note: Reference the appropriate controller manual for

more details on the installation of units with

factory-mounted controls.

5. Use a bar clamp to pull adjacent shipping section lifting

lugs together.

6. For indoor units sizes 66-120 and for outdoor units size

10-120, a wedge block is provided to aid in pulling and

aligning the units together. Attach the wedge blocks to

both sides of the units being pulled together, matching

the correct wedge block with the correct hole pattern.

See Figure 29, p. 30.

7. Verify that the subassembly with the overhang profile

on the roof is higher than the mating subassembly. If it

is not, raise one end of the subassembly and bring the

unit together. See Figure 26.

8. Due to unlevel floor and platforms, the roof may be

misaligned as shown in Figure 26. A common solution

is to raise one end of the shipping section to clear the

hemming before pulling the units together. 9. In addition, an adjustment can also be made to the

height of the roof of either subassembly.

At the center

(width-wise) of the unit, measure the height of each

adjacent subassembly and verify that the

subassembly with the overlap sheet metal is higher

than the mating subassembly roof. If it is not, adjust

the height of either subassembly by loosening the

screws in the vertical channels or component

structure and adjust the height of the roof. See

Figure 27

and Figure 28).

14. Install the section-to-section screws inserting the

appropriate screws through the overlapping flanges

using a powered impact gun and taking care not to

strip the screws. Outdoor air handlers will ship with a

seam cap that is to be installed over the section-to-

section seams. Factory-supplied butyl tape must be

applied over the seam prior to seam cap being applied.

See Figure 30.

15. For outdoor air handlers, attach roof overhang angle

with number 10 screws. Join outdoor roof panels

together at the seams in the direction perpendicular to

airflow and secure them in place with 5/16-inch x 3/4-

inch bolts and 5/16 lock nuts. Install the roof joint strip

to cover the seam between two outdoor roof panels in

the perpendicular to airflow direction of. Use 3/8-inch

butyl tape to cover the seam between two outdoor roof

panels overhang at the side the unit. Bend joint strip

over roof panel and use two number 10 sheet metal

screws (one in each roof panel) to secure joint strip.

Trim the roof joint strip to insure that it does not

protrude more than 1/16-inch beyond outdoor roof

overhang (see Figure 31).

Indoor Dual-Path SDU/Winterizer

Assembly

A dual-path, Split Dehumidification Unit (SDU)/winterizer

air handler consists of two units that are stacked together

in a draw-thru arrangement that share one supply fan. The

unit on the first level (primary unit) is designed to handle

the return air and is larger than the unit on the second level

(secondary unit), which is designed to handle outside air.

Factory-designed unit support brackets are provided with

all factory-approved, dual-path SDUs or winterizer air

handlers.

• A horizontal SDU/winterizer dual-path air handler

incorporates a horizontal supply fan on the first level

with a top opening in the primary unit that aligns with

a bottom opening in the secondary unit.

• A vertical SDU/winterizer dual-path air handler

incorporates a vertical supply fan on the second level

with a back opening that aligns with a front opening in

the secondary unit.

To assemble air handlers utilizing factory-approved and

factory-provided dissimilar unit sizes for horizontal SDU or

winterizer applications, join all similar size shipping

sections per “Section-to-Section Assembly” on page 27.

Horizontal SDU/Winterizer Air Handler

Assembly

To assemble dissimilar unit sizes for an indoor horizontal

SDU/winterizer configuration:

1. Locate the mounting hardware and gasket material.

Note: Black unit support brackets ship pre-installed on

the primary (larger) unit section.

2. Apply gasket in direction of airflow between the black

unit support brackets to the roof of the primary unit.

See Figure 44. The gasket needs to be placed such that

it will be directly under the integral base frame of the

secondary (smaller) unit to be stacked on top. The

secondary unit will be centered along the width on the

primary unit.

3. If there is an opening in the roof of the primary unit,

apply gasket perpendicular to airflow on the roof next

to the opening (air entering side only).

4. Lift the secondary unit, following instructions in

“General Lifting Considerations” on page 22 (see

Figure 11), and place on the black unit support brackets

(see Figure 45). The secondary unit must be centered

on the primary unit between the black unit support

brackets.

WARNING

Heavy Objects!

Do not stack air handlers unless factory-designed and

factory-approved. When stacking units, factory-

designed unit support brackets must be used. Stacking

units without factory-approval and without factory-

provided support brackets could result in the base unit

collapsing under the weight of the top unit which could

result in death or serious injury and property damage.

unit at the bottom of the opening (see Figure 48.

3. Lift the secondary unit, follow instructions in “General

Lifting Considerations” on page 22 (see Figure 11), and

place on the black unit support brackets (see Figure 45,

p. 42. The secondary unit must be centered on the

primary unit between the black unit support brackets.

Component Installation Requirements

CLCH-SVX07C-EN 45

Component Installation Requirements

The components in the air handler may have installation

requirements that could affect the unit’s performance.

Diffuser Section

Diffuser sections are usually placed between a fan and a

downstream coil or filter. Because placement is critical to

unit performance, verify the correct placement of the

diffuser section before assembling the unit (see Figure 51).

Filter Section

Bag and cartridge filter sections can be used as a pre-filter

section, a final filter section, or both. This use is

determined by the filter’s placement in relation to the fan.

• A final filter is placed after the fan.

• A pre-filter is placed before the fan.

Note: Cartridge and bag filters provided by Trane are

fitted with a 7/8-inch header that fits in the filter

track. If using filters supplied by another

manufacturer, filters should be purchased with a 7/

8-inch header. In some cases it may be necessary to

gasket other manufacturers’ filters to ensure a

good air seal.

Filters should be installed when the unit is set. This will

protect internal components, such as the heating and

cooling coils.

Final Filter Section

A final filter section should not be bolted directly to the

face of a fan section. One or more intermediate sections

must be placed between the fan discharge and the filter

section.

Pre-Filter Section

A pre-filter section has no special installation

requirements unless placed directly upstream of a plenum

fan. In these configurations, ensure a blank section is

placed between the fan inlet and the filter section.

Trane recommends the use of disposable pre-filters with

high-efficiency filters. Disposable pre-filters slide into the

mounting tracks just ahead of the bag/cartridge filters.

Filter Installation

To install filters:

1. Disconnect the power to the unit.

2. Open the filter section access door.

3. Slide the filters into the tracks.

Note: Bag filters must be installed with the pleats in the

vertical plane.

4. The block-off is permanently installed and will create a

seal when the access door is closed.

5. Close the access door slowly to allow any gasketing to

compress.

Figure 51. Diffuser placement sizes 3 to 120

Airflow

WARNING

Hazardous Voltage!

Disconnect all electric power, including remote

disconnects before servicing. Follow proper lockout/

tagout procedures to ensure the power can not be

inadvertently energized. Failure to disconnect power

before servicing could result in death or serious injury.

Fan Section

The fan section can be configured as either draw-thru or

blow-thru. Review the submittals and unit tagging

information prior to assembly to determine placement.

Fan Isolation

The fan-and-motor assembly is internally isolated. The fan

and motor bases are bolted to a minimum of four spring

isolators. The isolators are secured to the fan section

support base.

Shipping tie-down bolts are bolted adjacent to the

isolators between the fan isolation base and the isolator

support frame. The shipping tie-downs secure the

isolation base to the support assembly to prevent any

damage to the fan section during shipment.

Note: Remove the tie-downs only if the factory-provided

isolation is to be used.

Adjusting the Isolators

Once the shipping tie-downs are removed and the internal

isolation is released, it may be necessary to adjust the

isolators to achieve the proper operation height of the fan

and motor isolation base.

Minimum required clearances are listed in Table 10. To

determine the isolator clearances on all unit sizes,

measure between the top of the cabinet channel and the

bottom of the isolation base channel. See Figure 69,

Figure 70, Figure 71, and Figure 72.

WARNING

Hazardous Service Procedures!

The maintenance and troubleshooting procedures

recommended in this manual could result in exposure

to electrical, mechanical or other potential safety

hazards. Always refer to the safety warnings provided

throughout this manual concerning these procedures.

Unless specified otherwise, disconnect all electrical

power including remote disconnect and discharge all

energy storing devices such as capacitors before

servicing. Follow proper lockout/tagout procedures to

ensure the power can not be inadvertently energized.

When necessary to work with live electrical

components, have a qualified licensed electrician or

other individual who has been trained in handling live

electrical components perform these tasks. Failure to

follow all of the recommended safety warnings

provided, could result in death or serious injury. Table 10. Minimum isolator clearances (inches)

Damper Section

Dampers are factory-installed and adjusted and can be

found in mixing box/economizer sections. There are two

damper blade configurations available: parallel-blade and

opposed-blade.

Traq™ dampers are another type of damper available in

mixing box sections. Traq dampers have only one blade

configuration - opposed. They have two control

applications available - standard Traq dampers and low-

flow Traq dampers. Low-flow Traq dampers are always not

linked and consist of two damper sets - one set for

minimum outside air measurement and one set for

economizing. Each will have its own VCM.

The air handler is available with factory-mounted controls

or end devices. If the unit is not ordered with controls or

end devices, it is the installer’s responsibility to provide

and install the damper actuators. Size the actuators

according to Table 12.

Mixing section and economizer dampers are designed for

the damper actuators to be direct coupled and installed in

the air stream. If other provisions are required,

modifications to the section will be the responsibility of

the installing contractor.

External face-and-bypass damper torque requirements

Opposed-Blade and Parallel-Blade Damper

Opposed-blade and parallel-blade airfoil dampers in unit

sizes 3-120, as well as internal and external face-and-

bypass sections, have centered dampers with an internal

jack-shaft (see Figure 86, Figure 87 and Figure 88). A 95-

degree actuator rotation gives a 90-degree blade travel.

Note: Damper blades should be checked for proper

operation from full open to full closed position

before unit start up. Damper blade positioning may

have changed due to shipping and handling

vibrations.

Figure 86. Typical mixing box configurations for unit sizes 3 to 120

Component Installation Requirements

CLCH-SVX07C-EN 79

Multizone Modules

Under certain operating conditions, condensation may

form on the cold deck portion of the multizone damper

section. To prevent this, insulate around the damper rods.

Be sure the insulation does not affect damper operation.

Zone Damper Operators

Zone damper operators are available factory-mounted

with factory-mounted controls or as a stand-alone end

device. If not factory-provided, the contractor is

responsible for providing these operators. In all cases, the

damper operator should be connected to the drive rod.

Adjusting Zone Dampers

Zone dampers should be installed and adjusted prior to

making duct connections, assuring proper setup of the

damper zones:

1. Check the damper blades to confirm they are not

binding. The blade should rotate 90 degrees.

2. Determine the number of zones required. The zone

damper is fitted with a linkage bar that connects all

damper zones.

3. Select the number of damper segments required for

the first zone.

4. Cut a section out of the damper linkage bar just after

the last lever in that zone.

Note: It may be necessary to remove the damper linkage

bar to cut it. To remove the linkage bar pry the “e”

rings from the blade axles and remove the bar.

5. Repeat steps 3 and 4 for the remaining zones.

6. Attach the damper operator drive rod to one blade axle

in each zone with the two-deck damper.

7. Use the self-drilling screws provided to mount the

bearing bracket assembly (see Figure 89).

Note: The drive rod kits ship in a separate box, found in

the fan module or the cold deck of the multizone

module.

Duct Connections

All duct connections to the air handlers should be installed

in accordance with the standards of the National Fire

Protection Association (NFPA):

• NFPA 90A for installing air conditioning and ventilating

systems other than residence type.

• NFPA 90B for residence-type warm air heating and air-

conditioning systems.

See unit submittal documentation for additional duct

mounting information.

Fan Discharge Connections

To ensure the highest fan efficiency, duct turns and

transitions must be made carefully, minimizing air friction

losses and turbulence. Proper ductwork installation, as

outlined by such organizations as Sheet Metal and Air

Conditioning Contractors National Association, Inc.

(SMACNA), should be followed closely.

Fan sections with rectangular and round openings have a

one-inch flange on the discharge that can be used to attach

the duct. When using lined ducts, the insulation should not

obstruct the discharge opening. For plenum fan sections

with bell mouth fittings, see “Bell Mouth Discharge

Connections” on page 82.

Component Installation Requirements

80 CLCH-SVX07C-EN

Connections made directly to the discharge opening of a

housed fan should have a minimum of three fan diameters

of straight duct before any turns or transitions. The

ductwork should be the same size as the fan discharge

opening. The first turn of the connection should be in the

same direction as the fan rotation as shown in Figure 90.

The air that the fan discharges into the duct is extremely

turbulent and requires some length of duct to stabilize.

Abrupt changes in ductwork directly off the fan discharge

may adversely affect fan performance and acoustics.

Damper Connections

Standard damper sections include mixing sections, filter

mixing sections, face dampers sections, internal face-and-

bypass sections, and economizer sections. There are two

damper blade configurations available - parallel-blade and

opposed-blade. Traq™ dampers are another type of

damper available in mixing box sections.

Ductwork attached to the standard damper sections

should be sized to fit the opening of the damper. Duct

opening dimensions are provided in the submittals. When

using lined duct, ensure that the insulation does not

obstruct the damper opening (see Figure 91 and

Figure 92).

Note: Damper blades should be checked for proper

operation from full-open to full-closed position

before unit start up. Damper blade positioning may

have changed due to shipping and handling

vibrations.

Discharge Plenum Connections

Discharge plenum sections are available with or without

openings. Sections with rectangular and round openings

have a framed opening that can be used to secure the duct

to the frames. If the duct is lined, it is important the

insulation does not obstruct the opening of the section.

For a discharge plenum with field-cut openings, attach the

duct to the side panel.

Bell Mouth Discharge Connections

Round duct connections to be fastened to plenum fan and

discharge plenum sections with bell mouth discharge

openings should be sized to attach to the casing or directly

to the bell mouth fitting. Attachment to the casing requires

the round duct diameter to be sized two inches larger than

the nominal bell mouth outlet. An angle ring with a flat

flange should be affixed to the round duct to secure the

duct to the casing (see Figure 96). Attachment to the bell

mouth fitting requires the duct and fitting to be insulated

by the installing contractor up to the bell mouth radius to

prevent condensation (see Figure 97). The bell mouth

fitting extends through the casing by one inch.

External Face-and-Bypass Connections

The external face-and-bypass damper sections will

require a field-fabricated duct to direct the bypass air into

the appropriate section. Duct sizing recommendations are

listed in Table 29.

When attaching a bypass duct to a downstream fan section

or access section, the section will have a factory-provided

opening. (see Figure 99, Figure 100, and Figure 101.)

When bypassing into an access section, remove a panel. It

is not necessary to cut an opening.

Coil Piping and Connections

General Recommendations

Proper installation, piping, and trapping is necessary to

ensure satisfactory coil operation and to prevent

operational damage:

• Support all piping independently of the coils.

• Provide swing joints or flexible fittings on all

connections that are adjacent to heating coils to

absorb thermal expansion and contraction strains.

• If the coil was ordered with factory-mounted controls,

install the control valves. The valves ship separately.

Note: The contractor is responsible for supplying the

installation hardware.

• For best results, use a short pipe nipple on the coil

headers prior to making any welded flange or welded

elbow type connections.

• Extended drain and vent connections are provided as

standard on D1 and D2 coils only. If extended drains

and vents are required on other water coils, they must

be field-installed or ordered as specials from the

factory.

• Pipe coils counterflow to airflow.

• When attaching the piping to the coil header, make the

connection only tight enough to prevent leaks.

Maximum recommended torque is 200 foot-pounds.

• Use pipe sealer on all thread connections.

• After completing the piping connections, seal around

pipe from inner panel to outer panel.

Drain Pan Trapping

Threaded condensate drain connections are provided on

only one side of the coil section. Pitch the connection lines

horizontal or downward toward an open drain. Trane

recommends installing a plug to facilitate cleaning of the

trap. The drain connection sizes are:

Figure 30 illustrates the proper trapping, piping, and

operation of the trap. Use the formula under the figure to

determine the correct minimum depth for the condensate

trap. If a section has a drain pan for cleaning purposes

only, it does not need a trap; however, a cap or shutoff

valve should be installed on the drain connection. Only

sections handling condensate, such as a cooling coil

section or moisture eliminator section, require a trap.

NOTICE:

Connection Leaks!

Use a backup wrench when attaching piping to coils

with copper headers to prevent damage to the coil

header. Do not use brass connectors because they

distort easily and could cause connection leaks.

NOTICE:

Over Tightening!

Do not use Teflon-based products for any field

connections because their high lubricity could allow

connections to be over-tightened, resulting in damage

to the coil header.

NOTICE:

Leakage!

Properly seal all penetrations in unit casing. Failure to

seal penetrations from inner panel to outer panel could

result in unconditioned air entering the module, and

water infiltrating the insulation, resulting in equipment

damage.

WARNING

No Step Surface!

Do not walk on the sheet metal drain pan. Walking on

the drain pan could cause the supporting metal to

collapse, resulting in the operator/technician to fall.

Failure to follow this recommendation could result in

death or serious injury.

NOTICE:

Water Damage!

When more than one module has a drain pain, trap

each module individually. Connecting all drains to a

common line with only one trap can result in

condensate retention and possible water damage to

the air handler or adjoining space.

Coil Piping and Connections

CLCH-SVX07C-EN 87

Steam Coil Piping

Air handlers fitted with steam coils have labeled holes for

piping penetrations. Figure 104 illustrates a typical steam

coil piping configuration. See Table 31 for the codes of

system components in these figures.

The coil condensate return line must be piped full size of

the condensate trap connection, except for a short nipple

screwed directly into the coil header’s condensate return

To prevent coil damage, complete the following

recommendations:

• Install a 1/2-inch NPT, 15 degree swing check valve

vacuum breaker with cracking pressure of 0.25 inches

Hg (3.4 inches water) or lower at the top of the coil. This

vacuum breaker should be installed as close to the coil

as possible.

• For coil type NS, install the vacuum breaker in the

unused condensate return tapping at the top of the

coil.

• Vent the vacuum breaker line to atmosphere or

connect it into the return main at the discharge side of

the steam trap

Note: Vacuum breaker relief is mandatory when the coil

is controlled by a modulating steam supply or

automatic two position (ON-OFF) steam supply

valve. Vacuum breaker relief is also recommended

when face-and-bypass control is used.

Proper steam trap installation is necessary for satisfactory

coil performance and service life. For steam trap

installation:

1. Install the steam trap discharge 12 inches below the

condensate return connection. Twelve inches provides

sufficient hydrostatic head pressure to overcome trap

losses and ensures complete condensate removal.

a. Use float and thermostatic traps with atmospheric

pressure gravity condensate return, with automatic

controls, or where the possibility of low-pressure

supply steam exists. (Float and thermostatic traps

are recommended because of gravity drain and

continuous discharge operation.)

b. Use bucket traps only when the supply steam is not

modulated and is 25 psig or higher.

Note: Trane steam coils require a minimum of 2 psi of

pressure to assure even heat distribution.

2. Trap each coil separately to prevent holding up

condensate in one or more of the coils.

3. Install strainers as close as possible to the inlet side of

the trap.

4. If installing coils in series airflow, control each coil

bank independently with an automatic steam-control

valve. Size the traps for each coil using the capacity of

the first coil in direction of airflow.

5. Use a modulating valve that has linear flow

characteristics to obtain gradual modulation of the coil

steam supply.

Note: Do not modulate systems with overhead or

pressurized returns unless the condensate is

drained by gravity into a receiver, vented to

atmosphere, and returned to the condensate

pump.

6. Pitch all supply and return steam piping down 1 inch

for every 10 feet in the direction of the steam or

condensate flow.

Note: Do not drain the steam mains or take-offs through

the coils. Drain the mains ahead of the coils

through a steam trap to the return line.

7. Ensure overhead returns have 1 psig of pressure at the

steam trap discharge for every 2 feet of elevation for

continuous condensate removal.

NOTICE:

Breaker Cracking Pressure!

The 1/2-inch NPT, 15 degree swing check valve vacuum

breaker is recommended because other vacuum

breakers, such as spring-loaded ball-check breakers,

have cracking pressures as high as 1.25 inches Hg (17

inches of water). Vacuum breakers with fitting sizes

smaller than 1/2 inch NPT are too small to relieve

vacuum quick enough to ensure complete condensate

drainage. Other types of swing check valve vacuum

breakers are acceptable if the fittings size is not smaller

than 1/2-inch NPT and the cracking pressure is not

larger than 0.25 inches HG (3.5 inches of water). Failure

to follow these instructions could result in equipment

damage.

NOTICE:

Coil Condensate!

Condensate must flow freely from the coil at all times

to prevent coil damage from water hammer, unequal

thermal stresses, freeze-up and/or corrosion. In all

steam coil installations, the condensate return

connections must be at the low point of the coil. Failure

to follow these instructions could result in equipment

damage.

Water Coil Piping

Figure 105, and Figure 106 illustrate typical water coil

piping configurations.

Type 5A, 5W, D1, W, UW, TT, P,2, P4, and P8 water coils are

self-venting only if the water velocity exceeds 1.5 feet per

second (fps) in the coil tubes. Type D2, UA, UU, and WD

water coils are self-venting only if the water velocity

exceeds 2.5 fps in the coil tubes. See the unit submittals for

coil water velocity. If the water velocity is below these

minimums, vent the coil by one of the following methods:

1. Install an air vent in the top pipe plug tapping of the

return header.

2. When the return line rises above the top of the coil,

vent from the top of the return header horizontally to

the return piping.

Note: TT coils are designed with larger than normal end

tube sheet holes to allow for maximum expansion.

Air leakage around tubes should be expected and

handled by capping over coil ends or by sealing

around tubes with a pliable sealant such as

silicone.

Liquid Lines

Line Sizing

Properly sizing the liquid line is critical to a successful split-

system application. The selected tube diameter must

provide at least 5°F [2.7°C] of subcooling at the expansion

valve throughout the operating envelope. Increasing the

size of the liquid line will not increase the available

subcooling.

Routing. Install the liquid line with a slight slope in the

direction of flow so that it can be routed with the suction

line. Minimize tube bends and reducers because these

items tend to increase pressure drop and to reduce

subcooling at the expansion valve. Liquid line receivers,

other than those that are factory-installed, are not

recommended.

Insulation

The liquid line is generally warmer than the surrounding

air, so it does not require insulation. In fact, heat loss from

the liquid line improves system capacity because it

provides additional subcooling.

Components

Liquid-line refrigerant components necessary for a

successful job include a filter drier, access port, solenoid

valve, moisture-indicating sight glass, expansion valve(s),

and ball shutoff valves. Figure 108 illustrates the proper

sequence for positioning them in the liquid line. Position

the components as close to the evaporator as possible.

•Filter drier. There is no substitute for cleanliness during

system installation. The filter drier prevents residual

contaminants, introduced during installation, from

entering the expansion valve and solenoid valve.

•Access port. The access port allows the unit to be

charged with liquid refrigerant and is used to

determine subcooling. This port is usually a

Schraeder® valve with a core.

•Solenoid valve. In split systems, solenoid valves

isolate the refrigerant from the evaporator during off

cycles; under certain conditions, they may also trim the

amount of active evaporator as compressors unload.

Generally, the “trim” solenoid valve is unnecessary for

variable-air-volume comfort-cooling applications, and

is only required for constant-volume applications

when dehumidification is a concern.

•Moisture-indicating sight glass. Be sure to install one

moisture-indicating sight glass in the main liquid line.

The only value of the sight glass is its moisture

indication ability. Use actual measurements of

temperature and pressure—not the sight glass—to

determine subcooling and whether the system is

properly charged. The moisture indicator/sight glass

must be sized to match the size of the liquid line at the

thermal expansion valve.

•Thermal expansion valve. The expansion valve is the

throttling device that meters the refrigerant into the

evaporator coil. Metering too much refrigerant floods

the compressor; metering too little elevates the

compressor temperature. Choosing the correct size

and type of expansion valve is critical to assure it will

correctly meter refrigerant into the evaporator coil

throughout the entire operating envelope of the

system. Correct refrigerant distribution into the coil

requires an expansion valve for each distributor.

The thermal expansion valve must be selected for proper

size and capacity. The size of the expansion valve should

cover the full range of loadings. Check that the valve will

successfully operate at the lightest load condition. For

improved modulation, choose expansion valves with

balanced port construction and external equalization.

Cut the process tube and cap assembly from the liquid

connection as shown in Figure 109 and install the

expansion valve directly to the liquid connections.

NOTICE:

Valve Damage!

Disassemble the thermal expansion valve before

completing the brazing connections. If necessary, wrap

the valve in a cool, wet cloth while brazing. Failure to

protect the valve from high temperatures could result

in damage to internal components.

Suction Lines

Line sizing

Proper suction-line sizing is required to guarantee the oil

returns to the compressor throughout the system’s

operating envelope. At the same time, the line must be

sized so that the pressure drop does not excessively affect

capacity or efficiency. To accomplish both objectives, it

may be necessary to use two different line diameters: one

for the horizontal run and for vertical drops, and another

for the vertical lifts.

Routing

To prevent residual or condensed refrigerant from “free-

flowing” toward the compressor, install the suction line so

it slopes slightly—that is, by ¼ inch to 1 inch per 10 feet of

run—toward the evaporator. When the application

includes a suction riser, oil must be forced to travel the

height of the riser. Riser traps and double risers are

unnecessary in the suction line when the refrigerant coil is

used with Trane condensing units.

Avoid putting refrigerant lines underground. Refrigerant

condensation or installation debris inside the line, service

access, and abrasion/corrosion can quickly impair

reliability.

Insulation

Any heat that transfers from the surrounding air to the

cooler suction lines increases the load on the condenser

(reducing the system’s air-conditioning capacity) and

promotes condensate formation (adversely affecting

indoor air quality). After operating the system and testing

all fittings and joints to verify the system is leak-free,

insulate the suction lines all the way to inner side panel to

prevent heat gain and unwanted condensation.

Components

Installing the suction line requires field installation of

these components: a filter, access port, and a Frostat™

control when the refrigerant coil is used with Trane

condensing units. Position them as close to the

compressor as possible.

Note: Placement of the Frostat control is illustrated in

Figure 108 on page 90.

•Filter. The suction filter prevents contaminants,

introduced during installation, from entering the

compressor. For this reason, the suction filter should

be the replaceable-core type, and a clean core should

be installed after the system is cleaned up.

•Access port. The access port is used to determine

suction pressure. This port is usually a Schraeder valve

with a core.

•Frostat™ coil frost protection. The Frostat control is the

preferred method for protecting evaporator coils from

freezing when the refrigerant coil is used with Trane

condensing units. It senses the suction-line

temperature and temporarily disables mechanical

cooling if it detects frost conditions. The control is

mechanically attached to the outside of the refrigerant

line, near the evaporator, and wired to the unit control

panel.

•Ball shutoff valve. Adding manual, ball-type shutoff

valves upstream and downstream of the filter

simplifies replacement of the filter core.

External communications port

Units with a factory-provided DDC controller can include a

service module (see Figure 125) with an external

communications port when purchased. Both the operator

display and Rover service tool can be connected without

shutting off the unit through the external communications

port. Open the cover plate on the service module and plug

into the RJ-11 port for the operator display or the RS 485

port for the Rover service tool. This enables continuous

operation of the air handler without disruption to the

operating conditions of the unit. When servicing of the unit

is complete, close the cover plate on the service module to

eliminate any air leakage path.

• If differential pressure switch is provided on filter rack,

adjust per system requirements.

• Inspect electrical connections to the unit and unit

controllers.

– Connections should be clean and secure.

– Compare the actual wiring with the unit diagrams.

– Reference the appropriate controller manual for

more details about starting units with factory-

mounted controls.

• Check piping and valves for leaks. Open or close the

valves to check for proper operation. Drain lines should

be open.

• Leave this manual with the unit.

Fan-Related Checks

• If the unit is not externally isolated, ensure that the fan

isolator tie-down bolts have been removed. See “Fan

Isolation” section on page 62 for more information.

• Rotate all fan wheels manually to confirm they turn

freely in the proper direction.

• Check fan shaft bearings, fan wheel, and drive sheave

set screws for proper torque settings (see Table 35 on

page 111.

– Fan sheaves should be tight and aligned.

– Bearing set screws should be torqued. See Tab le 4 8

on page 124 for torque values.

• Check fan drive belt tension. See “Tension the Fan

Belt” section on page 109.

• Inspect fan motor and bearings for proper lubrication,

if necessary. See “Fan Bearing Lubrication,” on

page 124.

Coil-Related Checks

:

• Ensure coil and condensate drain piping connections

are complete.

• Check the piping and valves for leaks.

– Open or close the valves to check operation.

– The drain lines should be open.

• If unit has a refrigerant coil, ensure that it has been

charged and leak-tested according to the instructions

provided with the condenser equipment. Adjust the

superheat setting.

• Remove all foreign material from the drain pan and

check the pan opening and condensate line for

obstructions.

• For steam coils, slowly turn the steam on full for at least

10 minutes before opening the fresh air intake on units

with fresh air dampers.

WARNING

Hazardous Voltage w/Capacitors!

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. For variable frequency drives

or other energy storing components provided by Trane

or others, refer to the appropriate manufacturer’s

literature for allowable waiting periods for discharge of

capacitors. Verify with an appropriate voltmeter that all

capacitors have discharged. Failure to disconnect

power and discharge capacitors before servicing could

result in death or serious injury.

For additional information regarding the safe discharge

of capacitors, see PROD-SVB06A-EN

NOTICE:

Proper Water Treatment!

The use of untreated or improperly treated water in

coils could result in scaling, erosion, corrosion, algae or

slime. It is recommended that the services of a qualified

water treatment specialist be engaged to determine

what water treatment, if any, is required. Trane

assumes no responsibility for equipment failures which

result from untreated or improperly treated water, or

saline or brackish water.

Start-Up

CLCH-SVX07C-EN 107

Motor-Related Checks

• Locate installation manual from the motor

manufacturer for the specific motor installed. This can

be found by contacting the motor manufacturer’s

representative. The motor manufacturer’s

recommendations take precedence for all matters

related to the start-up and routine maintenance of the

motor.

• Check the motor lubrication for moisture and rust.

– Remove and clean grease plugs to inspect.

– If moisture is present, consult an authorized repair

shop for bearing inspection/replacement. This may

require removal and transport of motor.

– If no moisture is present, refer to the motor

manufacturer’s lubrication recommendations for

proper lubrication.

– The motor manufacturer may recommend

lubricating the motor as part of their routine start-

up instructions.

• Check motor winding. An acceptable winding

resistance reading is from 6 meg-ohms to infinity. If

reading is less than 5 mega-ohms, the winding should

be dried out in an oven or by a blower.

• Inspect the entire motor for rust and corrosion.

• Bump-start the unit and confirm the fan wheel rotates

properly, as indicated by the rotation arrow located on

the fan housing.

Note: For motor warranty needs, contact your local Trane

sales office.

Unit Operation

Before complete start-up, bump-start the unit and confirm

the fan wheel rotates properly, as indicated by the rotation

arrow located on the fan housing.

After initial startup:

• Calculate the motor voltage imbalance, notifying the

power company to correct unacceptable imbalances.

• Periodically check the fan belt tension.

Calculate Motor Voltage Imbalance

After startup, measure the motor voltage and amperage

on all phases to ensure proper operation. The readings

should fall within the range given on the motor nameplate.

The maximum allowable voltage imbalance is 2 percent.

Voltage imbalance is defined as 100 times the sum of the

deviation of the three voltages from the average, divided

by twice the average voltage. For example, if the three

measured voltages are 221, 230 and 227, the average

voltage would be 226 volts. The percent of voltage

imbalance is then calculated.

In the example, 2.2 percent imbalance is not acceptable

and the power company should be notified to correct it.

VFD Programming Parameters

Units shipped with an optional variable frequency drive

(VFD) are preset and run-tested at the Trane factory. If a

problem with a VFD occurs, ensure that the programmed

parameters listed in Table 33 have been set. If trouble still

persist after verifying factory parameters are correct, call

Trane Drive Technical Support at 1-877-872-6363. Have the

unit serial number from the drive available for the

technical support representative. The technician will

determine if drive can be repaired or needs to be replaced.

Tension the Fan Belt

Proper belt tension is required to ensure maximum

bearing and drive component life and is based on motor

horsepower requirement. A label located on the bearing

support on the drive side of the unit lists all drive parts, the

proper belt tension, and deflection for that tension for the

specific drive (Figure 126).

If the drive is changed from the original, proper belt

tension can be estimated using Table 34.

The correct operation tension for a V-belt drive is the

lowest tension at which the belts will not slip under the

peak load conditions. It may be necessary, however, to

increase the tension of some drives to reduce excessive

belt flopping or to reduce excessive startup squealing.

Check the fan belt tension at least three times during the

first days of operation because there is a rapid decrease in

tension until the belt settles in. To measure belt tension,

use a belt tensiometer (see Figure 127). Determine actual

deflection by depressing one belt with the belt

tensiometer and measuring the deflection relative to the

other belts or to belt line (see Figure 128). Adjust the belt

tension to the correct pounds force and tighten all set

screws to the proper torque.

NOTICE:

Belt Tension! (2 of 2)

Do not over-tension belts. Excessive belt tension will

reduce fan and motor bearing life, accelerate belt wear

and possibly cause shaft failure. Under tensioning belts

is the primary cause of premature belt failure. Belts

should not squeal at startup. Recheck belt tension after

8 hours, 24 hours, and 100 hours of operation and

monthly thereafter.

Determine Fan Speed

Fan speed can be determined using a strobe-type

tachometer, or revolution counter.

Check unit vibration if the fan speed is changed more than

five percent from the original designed speed, or if parts

such as shafts, fan wheels, bearings, or other drive

components are replaced. Do not exceed the maximum

fan speed.

Pay particular attention to any vibration, noise, or

overheating of the motor and fan bearings; however, note

that bearings may run warm during break in.

WARNING

Live Electrical Components!

During installation, testing, servicing and

troubleshooting of this product, it may be necessary to

measure the speed of rotating components. Have a

qualified licensed service individual who has been

properly trained in handling exposed rotating

components perform these tasks. Failure to follow all

safety precautions when exposed to rotating

components could result in death or serious injury.

Start-Up

CLCH-SVX07C-EN 111

Align Fan and Motor Sheaves

Align the fan and motor sheaves using a straightedge. The

straightedge must be long enough to span the distance

between the outside edges of the sheaves. When the

sheaves are aligned, the straightedge will touch both

sheaves at points A through D (see Figure 129) to confirm

the shaft is parallel. For uneven width sheaves, place a

string in the center groove of both sheaves and pull tight.

Adjust the sheaves and tighten the sheave set screws to

the proper torque given in Table 35.

Check Multiple Belts

Tighten the belts slightly and rotate the drive several

times.

On multiple belt drives, ensure the force of deflection is

approximately the same on each belt by pushing each belt

in an equal distance at a point halfway from each sheave

(see Figure 129). If this force is not the same for each belt,

the motor and fan shaft are not parallel. Realign as

required. After realignment, tighten the belts again to the

standard belt tensioning specifications. If the force is still

not the same for all belts, the belts or sheaves are worn

and must be replaced.

Airflow Measuring Systems

Traq™ Dampers

Traq dampers are low-leak dampers that modulate and

measure airflow. Each Traq damper section is supplied

with a factory-mounted ventilation control module (VCM)

on the interior of the mixing box section. The VCM has an

input terminal for power and an output terminal for air

velocity (see Figure 130). A direct-digital controller

controls the factory-mounted and wired actuators.

VCM (Transducer) Calibration.

The VCM has an auto-

zero function that recalibrates the transducer once every

minute. When troubleshooting, allow for the recalibration

time before making any measurements.

Input Power.

The only input the VCM needs is the 24 Vac

power connected to terminals 1TB1–5 and 1TB1–6.

Output Velocity Signal.

The 2 to 10 Vdc linear output

signal from the VCM represents air velocity. This voltage

can be converted to represent airflow (cfm or L/s) using the

formula below and Table 36.

Table 37. In Table 38 through Figure 45, the cfm at 10Vdc

is a calculated value based on area and peak

velocity. In certain situations, it can be

advantageous to raise the velocity of air

through the remaining Traq dampers by

closing off one or more dampers in the unit. The

cfm at 10Vdc can be recalculated based on the

proportion of remaining Traq dampers or by

multiplying the remaining area of dampers by

peak velocity. Calculations are based on VCM

voltage versus airflow at sea level.

Figure 131. Traq damper terminal connections

Airflow = k (cfm @ 10V)

or

Airflow = k (L/s @ 10V)

For example, if the VCM on a size 30 air handler at sea

level (k=1) has a 10-volt signal, it would represent

24,492 cfm (11,559 L/s) through the Traq damper. If

the voltage were 6 volts, airflow through the Traq

damper would be 12,246 cfm (5779 L/s).

Trane utilizes AMCA certification for airflow measuring stations. Trane certifies that the Traq damper

herein is licensed to bear the AMCA seal. The ratings shown are based on tests and procedures performed

in accordance with AMCA Publication 611 and comply with the requirements of the AMCA Certified

Ratings Program.

The certification program provides the engineer and owner assurance that manufacturer-published

performance ratings for airflow measurement stations are accurate and repeatable. Trane Traq dampers

are certified with the integral ventilation control module which converts differential pressure to an

electronic signal for control.

Refer to Performance Climate Changer Air Handler catalog CLCH-PRC015-EN for Traq damper testing and

rating information.

CLCH-SVX07C-EN 117

Fan Inlet Airflow Measuring System

A fan inlet airflow measuring system is available on many

centrifugal and plenum fans. Each system comes with a

differential pressure transmitter. The minimum diameter

is connected to the LO port of the transmitter and the

reference pressure point is connected to (or actually is) the

HI port of the transmitter.

Wiring

The transmitter requires 24VDC power on terminals 1 (+)

and 2 (ground) of the transmitter. When the airflow

measurement system is ordered with a factory-mounted

MP580 controller, the 24 VDC power will be supplied.

In the absence of a factory-provided MP580 controller, the

installing contractor must ensure the transmitter has

24VDC power.

Note: Ensure that the transmitter has a separate power

source.

Transmitter Sizing

The Trane specification requires that the flow meter option

have a total accuracy of 5 percent. The total accuracy is a

combination of:

• how accurately the flow meter itself is in sensing

airflow

• how accurately the transmitter senses the differential

pressure

• how accurately the controller translates the signal

from the transmitter to a differential pressure.

Selecting the proper transmitter is critical in order to get

accurate airflow measurements. How accurately the

transmitter senses the differential pressure is dependent

on:

• the pressure range selected

• accuracy of the selected transmitter

Trane air handlers use either a 0-20 inch or a 0-40 inch

range transmitter as standard. To sufficiently cover VAV

turndown on the smallest fans with the above range, a

transmitter with an accuracy of 0.25 percent (full scale) is

used as standard. If a field-provided transmitter with a

lower accuracy is selected, the range should be chosen

closer to the actual, maximum pressure differential

expected for the application.

The transmitter outputs a signal that represents the

differential pressure which is used to calculate airflow. To

adequately calculate and display the airflow for the

smaller fans, ensure that the analog input is programmed

with enough decimal places to sufficiently represent the

pressure differential being measured. For instance, Rover

should be used to increase the number of decimal places

being used (to a maximum of 4) on an MP-580/581

controller in lieu of the default zero.

Note that the adjustment of the “Zero” and “Span”

controls on the transmitter itself are not required at time of

installation. The transmitter is factory-calibrated to the

range selected and cannot be significantly adjusted to

“tighten” the range closer to the pressure being read for

the given application. The adjustments are primarily

provided to account for any drift that may occur over time.

Transmitter Calibration

The transmitter is factory-calibrated to a specific pressure

range with either a 0-20 inch or 0-40 inch w.g. range being

used in most cases. To check calibration and to adjust if

necessary, consult the transmitter manufacturer or the

factory for specific procedures.

The transmitter outputs a linear, 2-10 VDC signal

representing a differential pressure measurement. With

this measurement, the airflow through the fan can be

calculated using the following equation:

Significant differences in elevation and/or temperature

will affect the density of air. For air at a constant, non-

standard density, a field-obtained K factor can be used.

Alternatively, the following equation can be used to

continuously correct the equation above:

Note: Alternative units, including SI, can be used in place

of the IP units above although the K-factor must be

converted appropriately.

CFM = K * SQRT(DP)

Where:

K = A constant factor that is unique for each fan. See “Constant

Constant Factor K

The constant factor K is unique for each fan and is

primarily a function of the area and other geometric

properties of the fan inlet. Pre-engineered factors are

available from the factory for fan types where the airflow

measurement system is available. See Table 46 for single-

fan K factors. For a multiple-fan system, the constant

factor K may need to be adjusted depending on how many

transmitters are supplied.

When a single transmitter is supplied in a multiple fan

system, one or more fans will be brought back to the

transmitter as a manifold and the airflow will represent the

total airflow for the system. As a result, the factor should

be adjusted as follows:

*If a fan fails in a multiple fan system where only one

transmitter is being supplied, and if the remaining fans will

continue to be used, the factor should be reduced

accordingly. Additionally, if the inactive fan was included

in the manifold back to the transmitter, the tubes from the

inactive fan should be temporarily removed and replaced

with tubes from an active fan (or simply plugged).

When a transmitter is supplied for each fan, the factor does

not need to be adjusted. The resulting airflow will

represent single-fan airflow. At the controller level, the

individual airflows should be summed to get the total

airflow. If a field-provided K-factor is to be used (see

below), the measured airflow for the system should be

divided by the number of active fans to get a single-fan

K-factor.

Where:

K = The final factor to be used for controller

programming.

N = The number of active* fans in the system.

Start-Up

120 CLCH-SVX07C-EN

Field-obtained factors can provide maximum accuracy. To

obtain the factor in the field, measure the differential

pressure output from the transmitter while measuring the

airflow through the system. Once these two values have

been measured, simply solve for K using the following

equation:

Maintenance

For a typical HVAC environment - especially with upstream

filtration - there should be little to no required

maintenance. In extreme cases or for mishaps (bearing

grease in the taps for example), the flow meter is easily

cleanable. The fan inlet airflow measuring system is

extremely simple: a few pressure taps, a few fittings, and

some tubing. Although unlikely, if any tap were to get

clogged, simply disconnect each side of the transmitter

and blast air in a reverse direction through the system.

External Insulating Requirements

The following areas should be specifically addressed, as

applicable:

• Supply and return water piping connections

• Supply and return refrigerant piping connections

• Condensate drain lines and connections

• Outdoor-air-intake duct connections

• Discharge duct connections

• Special requirements for low-temperature-air systems

K = ACFM/SQRT(DP)

Coil Winterization

Water coil winterization procedures consist primarily of

draining water from the coil before the heating season.

Trane recommends flushing the coil with glycol if coils will

be exposed to temperatures below 35 degrees.

Install field-fitted drains and vents to permit winterization

of coils not in use and to assist in evacuating air from the

water system during startup. If draining is questionable

because of dirt or scale deposits inside the coil, fill the coil

with glycol before the heating season begins.

Individual coil types determine how to properly winterize

the coil. To determine the coil type find the “Service Model

No of Coil” on the coil section nameplate. The coil type is

designated by the second and third digits on that model

number. For example, if the model number begins with

“DUWB,” the coil type is UW; if the model number begins

with “DW0B,” the coil type is W.

Note: On many unit sizes, there are multiple coils in the

coil section. Be sure to winterize all coils in a given

coil section.

To winterize type D1, D2, WL, LL, UA, UW, UU, W, P2, P4,

P8, WD, 5D, and 5W coils:

1. Remove the vent and drain plugs.

2. Blow the coil out as completely as possible with

compressed air.

3. Fill and drain the coil several times with full strength

glycol so that it mixes thoroughly with the water

retained in the coil.

4. Drain the coil out as completely as possible.

5. To ensure no water remains in the coil, do not replace

the vent and drain plugs until the coils are put back into

service.

Note: Use care in removing header plugs from Type P2,

P4, and P8 coils. Over-torquing may result in

twisted tubes.

Moisture Purge Cycle

By it’s very nature, any HVAC unit with a cooling coil serves

as a dehumidifier, reducing the surrounding air’s ability to

hold water vapor as its temperature falls. This normally

doesn’t present a problem when the unit is running.

However, when the fan stops, water vapor condenses on

the cold metal surfaces inside the air handler and remains

there until the air warms sufficiently to re-evaporate it.

This damp, dark environment—though temporary—can

encourage the growth of mold, mildew, and other

microbial contaminants.

NOTICE:

Coil Freeze-up!

Drain and vent coils when not in use. Trane

recommends glycol protection in all possible freezing

applications. Use a glycol approved for use with

commercial cooling and heating systems and copper

tube coils. Failure to do so could result in equipment

damage.

Routine Maintenance

CLCH-SVX07C-EN 127

Providing a moisture purge cycle 15 to 30 minutes after

shutdown disperses the cold, humid air inside the air-

handling system more evenly throughout the building.

This four-step cycle:

• Closes the outdoor air dampers.

• Turns off the cooling coil.

• Opens any variable-air-volume terminals connected to

the air handler.

• Operates the supply fan for 10 to 15 minutes.

Air movement discourages water condensation and

hastens re-evaporation of any condensate that does

happen to form. This simple preventative measure

effectively combats microbial growth and curbs moisture-

related deterioration of air-handling components.

Cleaning Non-Porous Surfaces

If microbial growth on a non-porous insulating surface

(closed cell insulation or sheet metal surface) is observed:

1. Disconnect all electrical power to the unit.

2. Wearing the appropriate personal protective

equipment, use a brush for sheet metal surfaces or a

soft sponge on a foil face or closed cell foam surface to

mechanically remove the microbial growth.

Note: Be careful not to damage the non-porous surface of

the insulation.

3. Install a block-off to prevent spray from going into a dry

section of the unit and/or system ductwork.

4. Thoroughly clean the contaminated area(s) with an

EPA-approved sanitizer specifically designed for HVAC

use.

5. Rinse the affected surfaces thoroughly with fresh

water and a fresh sponge to prevent potential

corrosion of the drain pan and drain line

6. Repeat steps 4 and 5 as necessary.

7. Confirm the drain line is open following the cleaning

process.

8. Allow the unit to dry thoroughly before putting it back

into service.

9. Replace all panels and parts and restore electrical

power to the unit.

10. Be careful any contaminated material does not contact

other areas of the unit or building. Properly dispose of

all contaminated materials and cleaning solution.

Cleaning Porous Surfaces

To clean a porous insulating surface (fiberglass

insulation):

1. Disconnect all electrical power to the unit.

2. Wearing the appropriate personal protective

equipment, use a vacuum device with a HEPA filter

(99.97 percent efficient at 0.3 micron particles) to

remove the accumulated dirt and organic matter.

Note: Be careful not to tear the insulation surface or

edges.

3. Confirm the drain line is open following the cleaning

process.

4. Allow the unit to dry thoroughly before putting it back

into service.

5. Replace all panels and parts and restore electrical

power to the unit.

6. Be careful any contaminated material does not contact

other areas of the unit or building. Properly dispose of

all contaminated materials and cleaning solution.

Ultraviolet (UV) Light

Maintenance

The intensity of the ultraviolet energy emitted from the

ultraviolet bulbs is dependent on the cleanliness and age

of the bulb. The surface of the bulb should be kept as clean

as possible for optimum intensity. Depending on the

filtration level of the HVAC system and the general hygiene

of the building, periodic cleaning may be necessary.

Before attempting any maintenance procedures, always

follow all warnings and cautions as detailed in this

maintenance section.

Cleaning the Bulbs

Note: If bulbs are found to be broken, see the proper

warning and cautions below regarding broken

bulbs and hazardous vapors.

1. Disconnect all electrical power to the unit and the

ultraviolet bulbs.

2. Wearing soft cloth gloves and safety glasses, use two

hands and firmly grasp the bulb at each end.

3. Rotate the bulb 90 degrees in either direction and move

bulb away from the fixture and out of unit.

4. Wipe down each bulb with a clean cloth and alcohol.

Avoid touching the bulb with bare hands as skin oils

can accelerate future glass soiling and degrade the

bulb performance.

5. Carefully return the bulb to the fixture and rotate it 90

degrees in either direction until it is firmly secured.

6. Close and latch all unit panels and reenergize power to

the lights.

Replacing the Bulbs

Ultraviolet bulbs should be replaced annually if operated

continuously or after 9,000 hours of use if operated

intermittently. Replacement bulbs must be the specific size

and wattage as originally supplied from the factory.

Note: Although the lights may continue to generate a

characteristic blue glow beyond 9,000 operating

hours, the ultraviolet radiation emitted by the bulbs

degrades over time and will no longer provide the

intended benefit.

1. Disconnect power to the HVAC unit and the ultraviolet

bulbs. SEE WARNING ABOVE.

2. Wearing soft cloth gloves and safety glasses, use two

hands and firmly grasp the bulb at each end.

3. Rotate the bulb 90 degrees in either direction and move

bulb away from the fixture and out of unit.

4. Carefully install a new replacement bulb in the fixture

and rotate it 90 degrees in either direction until it is

firmly secured.

5. If broken bulbs are found or if you are required to

dispose of used bulbs, the proper warning and

cautions must be followed.

6. Always use cloth gloves and suitable eye protection

when cleaning or replacing these bulbs. Bulbs may

break if dropped or handled improperly.

Disposal of Bulbs

UV bulbs, like fluorescent bulbs, contain mercury, which is

a regulated hazardous waste. The disposal requirements

for hazardous wastes are determined by local, state and

federal guidelines. Check all regulations before disposing

of bulbs to assure you have met all requirements.

Refer to the MSDS sheet from the bulb manufacturer for

additional disposal, handling and safety information.

After replacing bulbs, close and latch all unit panels and

reenergize power to the lights.

WARNING

Hazardous Voltage and Exposure to

Ultraviolet Radiation!

This product contains components that emit high-

intensity ultraviolet (UV-C) radiation which can be

harmful to unprotected eyes and skin. To avoid injury,
