Important Environmental Concerns!

Scientific research has shown that certain man-made chemicals can affect the ear th’s naturally occurring stratospheric ozone layer when released to the atmosphere. In part icular , several of the identified chemicals that may af fect the ozone layer are refrigerants that contain Chlorine, Fluorine and Carbon (CFCs) and those containin g Hydrogen, Chlorine, Fluorine and Carbon (HCFCs). Not all refrigerants containing these compounds have the same potential impact to the environment. Trane advocates the responsible handling of all re frigerants-including industry replacements for CFCs such as HCFCs and HFCs.

Responsible Refrigerant Practices!

Trane believes that responsible refrigerant practices are important to the environment, our customers, and the air conditioning industry. All technicians who handle refrigerants must be certified. The Federal Clean Air Act (Section 608) sets forth the requirements for handling, reclaiming, recovering and recycling of certai n refrigerants and the equipment th at is used in these service procedures. In addition, some states or municipalities may have additional requirements that must also be adhered to for responsible management of refrigerants. Know the applicable laws and follow them.

Ultraviolet (UV) Germicidal Irradiation Lights!

The United States Environmental Protection Agency (EP A) believes that molds and bacteria inside buildings have the potential to cause health problems in sensitive individuals. If specified, Trane provides ultraviolet lights (UV -C) as a factory-engineered and installed option in select commercial air handling products for the purpose of reducin g mi cro bi ol og ical growth (mol d an d bacteria) within the equipment. When factory provided, polymer materials that are susceptible to deterioration by the UV -C light will be substituted or shielded from direct exposure to the light. In addition, UV -C radiation can damage human tissue, namely eyes and skin. To reduce the potential for inadvertent exposure to the lights by operating and maintenance personnel, electrical interlocks that automatically disconnect power to the lights are prov ided at all unit entry points to equipment where lights are located.

Warnings, Cautions and Notices

WARNING

Contains Refrigerant!

System contains oil and refrigerant under high pressure. Recover refrigerant to relieve pressure before opening the system. See unit nameplate for refrigerant type. Do not use non-approved refrigerants, refrigerant substitutes, or refrigerant additives.

Failure to follow proper procedures or the use of non-approved refrigerants, refrigerant substitutes, or r efrigerant additive s could result in death or serious injury or equi pment dam ag e.

WARNING

Hazard of Explosion!

Use only dry nitrogen with a pressure regulator for pressurizing unit. Do not use acetylene, oxyg en or compr essed air or mixtur es containing them f or pressu re t esting. Do not use mixtur es of a hydrogen containing refrigerant and air above atmospheric pressure for pressure testing as they may become flammable and could result in an explosion. Refrigerant, when used as a tr ace gas should only be mixed with dry nitrogen for pressurizing units. Failure to follow these recommendations could result in death or serious injury or equipment or property-only damage.

WARNING

Equipment Damage From Ultraviolet (UV) Lights!

Trane does not r ecommend field installation of ultr aviolet lig hts in its air handlin g equipment f or the intended purpose of improving indoor air quality. High intensity C-band ultraviolet light is known to severely damage polymer (plastic) materials and poses a personal safety risk to anyone exposed to the light without proper personal protective equipment (could cause damage to eyes and skin). Polymer materials commonly found in HVAC equipment that may be susceptible include insulation on electrical wiring, fan belts, thermal insulation, various fasteners and bushings. Degradation of these materials can result in serious damage to the equipment.

Trane accepts no responsibility for the performance or operation of our air handling equipment in which ultraviolet devices were installed outside of the Trane factory.

WARNING

Personal Protective Equipment (PPE) Required!

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

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

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

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

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

For heating applications, a special motor may be required to withstand the higher temperatures. Motors with Class B insulation are acceptable for ambient temperatures up to 104º F, while motors with Class F insulation can withstand ambient temperatures to +140º F (60º C).

Note: Units with UL approval have a maximum ambient temperature requirement of 104ºF. The

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

on page 126 for more information.

Unit Description

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

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

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

Factory-Mounted Controls

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

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

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

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

address is given on the Trane sales order.

CLCH-SVX07C-EN 9

General Information

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

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

If there is not enough space inside the section, a crate or pallet will be loaded onto the bed of the truck. Chec k the P arts List on the Field Assembly drawing against the contents of the crate. Do not proceed with unit assembly until verification that all materials are present. Sometimes it is necessary to use more than one section to ship hardware. Please check all sections thoroughly before contacting your local Trane sales engineer to report missing hardware.

Resolving Shipping Damage

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

Note: Trane is not responsible for shipping da mage.

1 . Make specific notation, describing the damage, on the freight bill. Take photos of the damaged

material if possible.

2. Report all claims of shipping damage to the delivering carrier immediately and coordinate carrier inspection if necessary.

Note: Do not attempt to repair the unit without consulting the delivering carrier.

3. Notify your Trane sales representative of the damage and arrange for repair.

Note: Do not attempt to repair the unit without consulting the Trane sales representative.

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

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

not incurred after delivery.

Storage Recommendations

NOTICE: Corrosion!

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

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

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

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

storage.

12 CLCH-SVX07C-EN

General Storage

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

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

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

Long-Term Storage

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

While the unit is in storage:

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

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

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

Outdoor Storage Considerations

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

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

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

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

• Loosen the belt tension on the drive belts.

• Cover the unit securely with a canvas tarp.

• Do not stack units.

• Do not pile other material on the unit.

Pre-Installation Requirements

Preparing the Unit Site

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

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

weights).

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

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

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

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

on page 80.

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

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

CLCH-SVX07C-EN 13

Pre-Installation Requirements

NOTICE:

Microbial Growth!

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

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

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

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

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

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

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

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

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

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

lifting the unit to the roof.

Roof Curb Installation Checklist

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

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

General Lifting Considerations

 WARNING

Heavy Objects!

Always place, assemble, and suspend sections/subassemblies one at a time. Do not lift units in windy conditions. Do not raise units o verhead with personnel below unit. F ailu r e to foll ow th ese instructions could result in death, serious injury, or equipment damage.

 WARNING

Improper Unit Lift!

Test lift unit approximately 24 inches to verify proper center of gravity lift point. To avoid dropping of unit, reposition lifting point if unit is not level. Failure to properly lift unit could result in death or serious injury or possible equipment or property-only damage.

NOTICE: Equipment Damage!

Keep skid in place until unit is r eady to set. Do not mo ve unit or su bassembly without the skid in place as shipped from the factory. Premature skid removal could result in equipment damage.

Before preparing the unit for lifting, estimate the approximate center of gravity for lifting safety. Because of placement of internal components, the unit weight may be unevenly distributed, with more weight in the coil and fan areas. Approximate unit weights are pro vided in “Unit Dimensions

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

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

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

CLCH-SVX07C-EN 25

Installation - Mechanical

Rigging and spreader bars furnished by others

 WARNING

Heavy Objects!

Do not use cables (chains or slings) except as shown. Each of the cables (chains or slings) used to lift the unit must be capable of suppor ting the enti r e w eight of the unit. Lifting cables (chains or slings) may not be of the same length. Adjust as necessary for even unit lift. Other lifting arrangements may cause equipment or property-only damage. Failure to properly lift unit could result in death or serious injury.

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

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

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

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

• \For outdoor air handlers, 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. Attac h 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.

 WARNING

Heavy Objects!

Always place, assemble, and suspend modules/subassemblies one at a ti me. Placing, assembling, and/or suspending more than one module/subassembly at a time could result in death, serious injury, or equipment damage.

Forklifting Considerations for Indoor Units Size 3-30

NOTICE:

Equipment Damage!

Improper use of f o rk lifts could r e sul t in eq uipment damage. Fork l ifting from any location other than that recommended by Trane and indicated on the unit labels could result in unit damage. Trane is not responsible for equipment damage resulting from improper forklifting practices.

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 fork lift may be used to lif t a single section or smal l subassembly, provided the forks extend under both ends of the base frame, or as indicated in Figure 10. 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 bo th base rails.

Figure 10. Fork lift points with base rail

Unit Placement and Assembly

If the air handler ships in subassemblies or in individual sections, some assembly is required, including:

• Ceiling-suspended indoor unit assem bly; see See “Ceiling Suspension f or Indoor Air Handlers

Sizes 3-57” on page 30.

• Section-to-section assembly; see “Section-to-Section Assembly” on page 32.

 WARNING

Toxic Fumes!

Keep open flame away from unit exterior or interior. Do not weld or use cutting torch on the

28 CLCH-SVX07C-EN

exterior or interior of the unit. The unit contains polyurethane insulation. Failure to keep open flame away form unit exterior or interior could result in the production of toxic gas that could result in death or serious injury.

Unit Placement

Installation - Mechanical

NOTICE: Temperature Limit!

The internal sections of this unit containing electrical components must not exceed 104o F operating temperature. Internal sections of the unit not containing electrical components must not exceed 200o F temperature. Failure to comply with temperature requirements could cause equipment damage.

 WARNING

Heavy Objects!

Always place, assemble, and s uspend sections/subassemblies one at a time. Placing, assembling, and/or suspending more than one section/subassembly at a time could result in death, serious injury, or equipment damage.

NOTICE Microbial Growth!

The roof curb 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 may cause odors and damage to the equipment and building materials.

If a unit arrives in sections, then eac h 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 co r rect placement of all sections. If there are any discrepancies between the submi ttals and the unit tagging, contact your local T rane 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 page40 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 11 and Figure 12.

For proper operation, the unit must be installed level (z ero 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 49 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 for Indoor Air Handlers Sizes 3-57

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

 WARNING

Heavy Objects!

If a field-provided mounting frame is used for ceiling suspension, the installer/contractor must provide a ceilin g-suspended mountin g frame d esigned t o suppor t the leng th, width, an d w eight of the entire air-handling unit. Failure to use proper mounting frame, structural channels, and hangers could result in unit falling from its mounting location which coul d result in death or serious injury.

See “Unit Dimen sions and Weights” on page 16 for approximate weights.

Note: It is the building engineer’ s responsibility to size the structural c hannels and to pro vide the

appropriate hangers.

Structural channels in a field-provided frame can be mount ed parallel to airflow or perpendicular to airflow:

30 CLCH-SVX07C-EN

Installation - Mechanical

• For parallel-to-airflow channels, size channels based on a four-point load distribution (see

Figure 13.

• 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 14).

Figure 13. Typical suspension method using parallel

channels

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 lif ting 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 15). See Figure 7 and Table8 on page 27 for lug hole sizes.

• Bolt shipping splits together.

Note: The hanger rods must extend through the bottom of the bas e lug. It is the buil din g

engineer’s responsibi lit y to pr ovide the appropriate hangers.

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, c heck all sections thor oughly before contacting your T rane 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. R emo ve an y ship ping bol ts located on th e mounting surfaces of the sections (see Figure16).

3. Apply the gasketing to one of the mating surfaces; see Figure 16, Figure 17, and Figure 18.

Indoor Dual-Path Split Dehumidification Unit (SDU)/Winterizer Assembly

 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 using factory-provided support brackets could result in the base unit collapsing under the weight of the top unit which could result in death, serious injury and equipment damage.

A dual-path, SDU/winterizer air handler consists of two units that are stacked together in a drawthru 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 han dler incorpo rates a horiz o ntal 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.

Horizontal SDU/Winterizer Indoor Air Handler Assembly

To assemble dissimilar unit sizes in a horizontal SDU/winterizer configuration:

1. Locate the mounting hardware and gasket material.

Note: Black unit support brackets ship pre-installed on the prima ry (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 32. 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 w ill be centered along the width on the primary unit.

Component Installation Requirements

Airflow

Component Installation Requirements

The components in the air handler may have installation requirements that could affect the unit’s performance.

Diffuser Sections

Diffuser sections are usually placed between a fan and a downstream coil or filter. Because placement is critical to unit perfor mance, verify the correct placement of the diffuser section before assembling the unit (see Figure 39).

Figure 39. Diffuser placement sizes 3 to 120

Filter Sections

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 fit ted with a 7/8-inc h header that fits in the

filter track. If using filt ers 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 s ection is placed between the fan inlet and the filter section.

Trane recommends the use of disposable pre-filters with high-efficiency filters. Disposable prefilters slide into the mounting tracks just ahead of the bag/cartridge filters.

Fan Sections

Required clearance

The fan section can be configured as either draw-t hru or blow-thru. Review the su bmittals 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

Note: For additional information regarding the safe discharge of capacitors, see

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 9. T o determine the isolator clearances on all unit sizes, measure between the top of the cabinet c hannel and the bottom of the isolation base channel. See Figure 51, Figure 52, Figure 53, and Figure 54.

Seismic Isolation Requirements

Air handling equipment manufactured by Trane is capable of structurally and operationally withstanding the seismic response criteria as required by the International Building Codes (IBC) 2000,2003, 2006, 2009. Trane has third-party certification for IBC compliance for seismic applications for unit sizes 3-30. Certification for larger sizes is in process.

Note: If seismic isolation has been specified, the following requirem ents must be adhered to for

installation. Failure to follow these instruction would void the warranty.

Anchor Pattern

Figure 55. Seismic anchor pattern

Each module is considered a functional section; for example, fan section, coil section, access section, etc. Anch oring of the unit needs to be p laced at the designated locations according to the anchoring pattern for each functional section (see Figure 55).

If anchoring eac h functional section is difficult, then spacing between each anchor can be no longer than 46 inches.

Lifting lugs can be used as locations for anchoring the unit. For locations that do not have lifting lugs, additional anchors need to be installed at the construction site.

Anchor selection meets or exceeds IBC 2000, 2003, 2006 and 2009 compliance requirements.

CLCH-SVX07C-EN 63

Special Inspection per IBC Section 1704 is required on all installations. All anchors listed above must be installed to meet compliance.

Component Installation Requirements

Damper Sections

Dampers are factory-installed and adjusted and can be found in mixing box/economiz er sections. There are two damper blade configurations available: parallel-blade and opposed-blade.

T raq™ 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 10.

Opposed-Blade and Parallel-Blade Dampers

Opposed-blade and parallel-blade airfoil dampers in unit sizes 3-120 have centered dampers with an internal jack-shaft (see Figure 56). A 95-degree actuator rotation gives a 90-degree blade travel.

Note: Damper blades should be chec ked 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.

Component Installation Requirements

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.

Fan Discharge Connections

T o ensure the highest fan efficiency , duct turns and transitions must be made carefully, minimizing air friction losses and turbulence. Proper ductwork instal lation, as outl ined by such organizations as SMACNA (Sheet Metal and Air Conditio ning Contractors National Association, Inc.), should be followed closely.

Fan sections with rectangular and round openings have a one-inc h flange on the disc harge that can be used to attach the duct. When using lined ducts, the insulation shou ld not obstruct the discharge opening. For plenum fan sections with bellmouth fit tings, see “Bellmouth Discharge Connections”

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 57. 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.

Discharge Plenum Connections

Discharge plenum sections are available with or with out openings. Se ctions 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.

Bellmouth Discharge Connections

Round duct connections to be fastened to plenum fan and discharge plenum sections with bellmouth disc harge openings shoul d be siz ed to at tach to the casing or directly to the bellmouth fitting. Attac hment to the casing requires the round duct diameter to be sized two inches larger than the nominal bellmouth outlet. An angle ring with a flat flange should be af fixed to the roun d duct to secure the duct to the casing (see Figure 63). Attachment to the bellmouth fitting requires the duct and fitting to be insulated by the installing co ntractor u p to the b el lmou th radi us to preven t condensation (see Figure 64). The bellmouth fitting extends through the casing by one inch.

Coil Piping and Connections

General Recommendations

Proper installation, piping, and trappi ng is necessary to ensure satisfactory coil operation and to prevent operational damage:

• Support all piping independently of the coils.

• Provide swing joints or flexible fit ti ngs 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.

NOTICE: Connection Leaks!

Use a backup wrench when attac h ing piping t o 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.

• When attac hing the piping to the coil header , make the connection only tight enough to prevent leaks. Maximum recommended torque is 200 foot-pounds.

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.

• Use pipe sealer on all thread connections.

NOTICE: Leakage!

Proper ly seal all penetrations in unit casing. Failure to seal penetrations from inner panel to outer panel could result in unconditioned air entering the unit, and water infiltrating the insulation, resulting in equipment damage.

• After completing the piping connections, seal around pipe from inner panel to outer panel.

Do not walk on the sheet metal dr ai n pan. Walking on the drain pan could cause the su pporting metal to collapse. Failure of the drain pan could result in death or serious injury.

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 71 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 shutof f valve should be installed on the drain connection. Only sections handling co ndensate, such as a cooling coil s ection or moisture eliminator section, require a trap.

NOTICE:

Wa ter Damage!

When more than one section has a drain pain, trap each section individually. Connecting all drains to a common line with only one trap could result in condensate retention and possible water damage to the air handler or adjoining space.

Steam Coil Piping

Air handlers fitted with steam coils have labeled holes for piping penetrations. Fi gure 72 illustrates a typical steam coil piping configuration. S ee Table 24 for the codes of system components in these figures.

The coil condensate return line must be piped f ull size of the condensate trap connection, except for a short nipple screwed directly into the coil header’ s condensate return tapping. Do not b ush or reduce the coil return trapping size.

NOTICE: Vacuum 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 (1 7 inc hes of wat er). Vacuum break ers with fitting sizes smaller than 1/2 inch NPT

are too small to relieve vacuum quick enough to ensure complete condensat e dr ainage. Other types of swing check valv e v acuum br eak ers ar e 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 (3.4 inches of water). Failure to follow these instructions could result in equipment damage.

To prevent coil damage, complete the followin g recommendations:

• Install a 1/2-inch NPT, 15 degree swi ng check val ve vacuum breaker with cracking pressure of

0.25 inches Hg (3.4 inc hes water) or lower at the to p 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: V acuu m 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.

NOTICE: Coil Condensate!

Condensate must flow freely from the coil at all times to prevent coil damage from water hammer , unequal ther mal str esses, fr eeze-up and/or cor rosion. In all steam coil installations, th e condensate return connections must be at the low point of the coil. Failure to follow these instructions could result in equipment damage.

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 pro v ides 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, contro l 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.

Water Coil Piping

Figure 73, and Figure 74 illustrate

typical water coil piping configurations. T ype 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 selfventing 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.

Use Figure 76 to determine the proper, relative sequence of the components in the refrigerant lines that connect the condensing unit to an evaporator coil. Refer to “Examples of Field-Installed Evaporator Piping” on page 89 for more detailed schematics of evaporator piping.

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 siz e of the liquid line will not increase the available subcooling.

Routing. Install th e liquid line with a slight slope in the direction of flow so t hat 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 76 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

• Solenoid valve. In split systems, solenoid valves isolate the refrigerant from the evaporator during off cycles; under cer tain conditions, they may also trim the amount of active evaporator as compressors unload. Generally, the “trim” solenoid valve is unnecessary for variable-airvolume 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 indi cator/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.

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.

Coil Piping and Connections

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 77 and install the expansion valve directly to the liquid connections.

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 ver tical 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

CLCH-SVX07C-EN 87

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). Af ter 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 installa tion of these components: a filter , access port , and a Frostat™ control when the refrigerant coil is used with T rane condensing uni ts. Position them as close to the compressor as possible.

Note: Placement of the Frostat control is illustrated in Figure 76 on page 85.

• 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 Tr an e condensing units. It senses the suction-line temperature and temporarily disables mec hanical cooling if it detects frost conditions. The control is mec hanically attac hed 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.
