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 oz one 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. T rane advocates the responsible handling of all refrigerants-including industry replacements for CFCs such as HCFCs and HFCs.

must also be adhered to for responsible management of refrigerants. Know the applicable laws and follow them.

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 r equirements f or field wiring installat i on a nd 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/servi cing this unit, technicians MUST put on all P ersonal Protectiv e Equipment (PPE) recommended for the work being undertaken. AL WAYS r efer to appropr iate MSDS sheets and OSHA guidelines for proper PPE.

• When work ing with or ar ound hazar dous c hemicals, 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, tec hnicians 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.

Failur e to f ollow r ecommendations could resul t in death or serious injury.

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

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 expo sure 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.

Warnings, Cautions and Notices

WARNING

Equipment Damage F rom Ultra violet (UV) Lights!

Trane does not recommend field installa tion of ultraviolet lights in its air handling equipment for the intended purpose of improving indoor air quality. High intensity C-band ultra v io let 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 “Routi ne Maintenanc e” 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 coolin g coils, filters, and dampers.

Trane air handlers ship as complete assemblies or in subassemblies 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-andbypass sections, UL-approved electric heat sections, humidifiers, mixing boxes, moisture eliminator sections, exhaust dampers, controls, blenders and airflo w 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 m ou nte d 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 1 20 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 factorymounted starters or VFDs are supplied wit h 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 tec hnical application notes. The tec hnical applic ation notes i nclude the contro l sequencing, T rane Graphic Programming (TGP) and Rover set-up files for the specific unit selected. These resources are available through your local Trane sales office.

Wiring

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 follo w 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.

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.

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 lif t 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 shou ld 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 latc hes 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 s hip

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 obj e cts.

• 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: T rane 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 Damag e

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. R eport 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.

CLCH-SVX07C-EN 9

Pre-Installation Requirements

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!

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 storag e stains.

Note: All factory shipping protection shou ld be removed.

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. K e ep the equipment in the original container for protection and ea se 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 moisturetolerant. Factory protective coverings should be removed prior to storage.

Long-Term St orage

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 shaf t 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 or iginal 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 ra ised 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 a nd/or eq uipment r oom.

Pre-Installation Requirements

Screw securing roof felt to rigid insulation or 2 x 10

Flashing (field-supplied)

Roofing felt (field-supplied)

4 x 4 cant (field-supplied)

Roof deck Support channels

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.

• 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 mou nti ng 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

Figure 2. Cross section of typical curb installation on

new construction

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-inc h 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 und er the lip of the curb flanges and over the felt.

10. Apply sealant to the fou r 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.

See CLCH-SVN05A-EN Roof Curbs for P erformance 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 tac k welds or other equivalent methods. Properly supported decking sh ould be ins talle d inside the ai r handl er section of the curb when this method is used. See Figure 2.

General Lifting Considerations

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 crushi ng ope rator/technician which could result in death or serious injury and possible equipment or property-only damage.

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.

Before preparing the unit for lifting, estimate the approximate center of gravity for lifting safety. Because of placement of internal componen ts, the unit weight may be unevenly distributed, with more weight in the coil a nd fan areas. Approximate unit weights are provided in “Unit

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

submittals for actual section weight s. Test the unit for proper balance before liftin g.

For outdoor air handlers, preparation of the roof curb or pier mount and roof openings must be comple ted before lifting to the roof. See CLCH-SVN04A-EN Roof Curbs for Performance Climate Changer Air Handlers installation instructions for details.

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. A djust as necessary fo r ev en 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.

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, suc h 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.

• 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.

Figure 11. Lifting detail for unit sizes 3 to 120

• 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 suppo rts 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

NOTICE:

Equipment Damage!

Do not use a fork lift on air handlers or subassemblie s larger than size 30. Improper use of fork lifts on units larger than size 30 could result in equipment damage. Trane is not responsible for equipment damage resulting from improper fork lifting practices.

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

indoor air handlers/subassemblies larg er than size

30.

For unit sizes 3-30, a forklift may be used to lift a single section or small subassembly, pro vided the forks extend under both ends of the base frame, or a s indicated in

Figure 14. The forks should not contact the bott om of the

air handler. Units should only be lifted from the proper end identified by the lifting label on the u nit. A lif ting crane or other means should be used for larger units where forks cannot extend under both base rails.

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.

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 insulatio n. 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 104 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.

F operating

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 you r local Trane representative before proceeding.

Following the order of the sections on the unit submittals and tagging, individually place e ach unassemb led section or subassembly in the appropriat e installation location.

Note: Prior to placing fan section in the approp ri ate

installation location, verify shipping tie-downs have been removed.

For outdoor units, the pipe cabinet must also be m ounted as an individual section. Refer to “P ipe 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 unde r neath 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 Figure15 and Figure 16.

WARNING

Risk of Unit Dropping!

NOTICE:

Microbial Growth!

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.

Note: Piers beneath shipping splits must be structurally

sound to support the weight of the unit.

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 Figure17.

Note: Piers beneath shipping splits must be structurally

sound to support the weight of the unit.

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 fieldprovided wiring. Consider overall unit serviceability and accessibility before mounting, running wires (power), making cabinet penetrations, or mounting any components to the cabinet.

See “Component Install ation Re quirements” on page 45 for special assembly/installation consid erations.

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

Figure 17. Typical suspension method-parallel channels

• 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 18. Typical ceiling suspension-perpendicular

channels

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.

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

26 CLCH-SVX07C-EN

Installation - Mechanical

Hole diameter is 0.625 inches

Using Integral Base Frame

Figure 19. Ceiling suspension for unit sizes 3-57

• 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 requ ir e d 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 gusse t 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)

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:

Figure 20. Shipping gusset Figure 21. Coil structural gusset

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

CLCH-SVX07C-EN 27

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 mo unting surfaces of the sections (see Figure 22).

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

5. Use a bar clamp to pull adjacent sh ipping section lifting lugs together.

6. For indoor units sizes 66-120 and for outdoor units size 10-120, a wedge bloc k is provided to aid in pulling and aligning the units together. At tach the wedge bloc ks to both sides of the units being pulled together, matching the correct wedge block with the cor rect hole pat tern. See Figure 29, p. 30.

7. V erify 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 brin g 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

Figure 27. Adjust height of roof by adjusting vertical channels

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

WARNING

Heavy Objects!

Do not stack air handlers unless factory-designed and factor y-approved. When stacking units, facto r ydesigned unit support brackets must be used. Stacking units without factory-approval and without factoryprovided 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.

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 brac kets are provided with all factory-appro v ed , 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-Secti on Asse mbly” on page 27.

Figure 44. Apply gasket in direction of airflow

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 blac k unit support brac kets

(see Figure 45). The secondary unit must be centered on the primary unit between the black unit support brackets.

Figure 45. Place secondary unit on black unit support

brackets.

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 centere d 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 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 a ssembling the unit (see Figure 51).

Figure 51. Diffuser placement sizes 3 to 120

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 fil t ers provided by Tr ane are

fitted with a 7/8-inch header that fits in the filter track. If using filters supplied by another manufacturer, filters should be purc hased with a 7/ 8-inch h eader. 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.

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

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.

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-of f is permanently installed and will c reate a seal when the access door is closed.

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

Figure 52. Filter block-off placement

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.

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 determin e pl ace ment.

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 disc ha rge 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 licen sed electrician or other individual who has been trained in handling live electrical components perform these tasks. Fa ilure to follow all of the recommended safety warnings provided, could result in death or serious injury.

Fan Isolation

The fan-and-motor assembly is internally isolated. The fan and motor bases are bolted to a minimum of four spr ing

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-pro vided

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.

Damper Sectio n

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 ar e ano t her 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 lowflow T raq 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 fac tory-mounted contro ls 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.

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-andbypass 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 chan ge d due to shipping and handling vibrations.

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.

Figure 89. Setting the zone damper rods an d da mper

linkage

Multizone Modules

Under certain operating conditions, condensation may form on the cold deck portion of the multizone damper section. T o 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 remov e the bar.

Duct Connections

All duct connections to the air handlers should be installed in accordance with the standards of the National Fire Protection Association (NFPA):

• NFP A 90A for installing air conditioning and ventilating systems other than residence type.

• NFP A 90B for resid ence-type wa rm air heating and airconditioning systems.

See unit submittal docum e nta tion 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 insulati on should not obstruct the discharge opening. For plenum fan sections with bell mouth fittings, see “Bell Mouth Discharge

Connections” on page 82.

Airflow

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 change s in ductwork directly o ff the fa n disc harge may adversely affect fan performance and acoustics.

Damper Connections

Standard damper sections include mixing sections, filter mixing sections, face dampers sections, internal face-andbypass sections, and economizer sections. There ar e 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 provide d 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 pr oper

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, attac h 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. Attac hment 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.

Coil Piping and Connections

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.

• Use pipe sealer on all thread connections.

• After completing the pipi ng conne ction s, seal aroun d pipe from inner panel to outer panel.

Drain Pan Trapping

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:

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.

General Recommendations

Proper installation, piping, and tr ap ping 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-mounte d 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.

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.

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:

Unit size

NPT (national pipe thread) external

3-31 1-inch

35-58 1 1/4 inch

66-120 1 1/2 inch

Figure 30 illustrates the proper trapping, piping, and

operation of the trap. Use the formula under the figure to determine the correct minimu m 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.

Coil Piping and Connections

NOTICE:

Breaker Cracking Pressure!

The 1/2-inch NPT, 15 degree swing check valve vacuum breaker is recommended because oth er 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 ar e acceptable if the fittings siz e is not smaller than 1/2-inch NPT and the cracking pressure is not larger than 0.25 inches HG (3.5 inches of w ater). Failure to follo w th ese in structions could result in equipment damage.

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 a t the disc harge side of the steam trap

Note: V acuum breaker relief is mandatory when the coil

is controlled by a modulating st eam 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 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 follo w th ese in structions 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 inc hes provides sufficient hydro static 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 dr a in 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.

Water Coil Piping

Figure 1 0 5 , and Figure 106 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 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:

Figure 105. Typical piping for type 5W one-row water coil

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 splitsystem 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

• 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 compressor s unloa d. 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 in stall one moisture-indicating sight glass in the ma in 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 matc h the si ze of the l iquid line at the thermal expansion valve.

valve with a core.

• 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.

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.

CLCH-SVX07C-EN 91

Coil Piping and 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 vertical drops, and another for the vertical lifts.

Routing

To prevent residual or condensed refrigerant from “freeflowing” 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 undergro und. 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 Fr ostat 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 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.

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 appropriat e v oltmeter 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:

Use Copper Conductors Only!

Unit terminals are not designed to accept other types of conductors. Failure to use copper conductors could result in equipment damage.

Units intended for indoor use are available with starters or variable-frequency drives (VFDs) that are externally mounted in an enclosure or internally mounted in a recessed cabinet. Units intended for outdoor use are only available with internally mounted starters or VFDs. A typical internally mounted VFD is shown in Figure 116. A typical externally mounted VFD is shown in Figure 117.

T ypical wiring schematics for VFDs and starters are shown in Figure 123 and Figure 124, respectively. Unit specific wiring schematics are shipped with each unit.

All units with starters or VFDs that have direct-digital controllers (DDCs) are provided with line voltage to 24 V ac power transformers as shown in Figure 118. When provided, the line voltage to 24 Vac transformers are factory wired to the supply fan power feed. All units with factory-mounted controll ers, and no starters or VFDs, are provided with 120 Vac to 24 Vac control transformers, as shown in Figure 120, and require a separ ate 120V field connection. As with starters or VFDs, units intended for indoor use are available with DDCs mounted internally (see Figure 118) or externally (see Figure 119 and

Figure 120), while units intended for outdoor use are only

available with internally mounted DDCs. In units with 24Vac LED marine lights, the lights are wired

together to a single switc h located in the controls interface module. Figure 119 shows a typical mounting of the controls interface module with an externally mounted controller. When DDCs are provided, the lighting circuit is powered from the DDC power feed and does not require a separate power source. When marine lights are provided without DDCs, the lighting circuit requires a separate 120V field connection that powers the lights through a 120V to 24Vac power transformer.

A mounted GFCI receptacle is provided for all units that have DDCs or marine lights. The receptacle is mounted in the controls interface module (see Figure 119) with the unit light switch. The receptacle requires a separate 120V power feed.
