Important Environmental Concerns
Scientific research has shown that certain man-made chemicals can affect the earth’s naturally occurring stratospheric ozone layer when released to the atmosphere. In particular, several of the identified chemicals that may affect the ozone layer are refrigerants that contain Chlorine, Fluorine and Carbon (CFCs) and those containing Hydrogen, Chlorine, Fluorine and Carbon (HCFCs). Not all refrigerants containing these compounds have the same potential impact to the environment. Trane advocates the responsible handling of all refrigerants.
Important 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 according to local rules. For the USA, the Federal Clean Air Act (Section 608) sets forth the requirements for handling, reclaiming, recovering and recycling of certain refrigerants and the equipment that is used in these service procedures. In addition, some states or municipalities may have additional requirements that must also be adhered to for responsible management of refrigerants. Know the applicable laws and follow them.

WARNING
Proper Field Wiring and Grounding Required!
Failure to follow code could result in death or serious injury. All field wiring MUST be performed by qualified personnel. Improperly installed and grounded field wiring poses FIRE and ELECTROCUTION hazards. To avoid these hazards, you MUST follow requirements for field wiring installation and grounding as described in NEC and your local/state/national electrical codes.
WARNING
Personal Protective Equipment (PPE) Required!
Failure to wear proper PPE for the job being undertaken could result in death or serious injury. Technicians, in order to protect themselves from potential electrical, mechanical, and chemical hazards, MUST follow precautions in this manual and on the tags, stickers, and labels, as well as the instructions below:
· Before installing/servicing this unit, technicians MUST put on all PPE required for the work being undertaken (Examples; cut resistant gloves/sleeves, butyl gloves, safety glasses, hard hat/bump cap, fall protection, electrical PPE and arc flash clothing).

Outdoor Storage
NOTICE Unit Corrosion Damage!
Plastic tarps can cause condensation to form in and on the equipment, which could result in corrosion damage or wet storage stains. Use only canvas tarps to cover air handlers.
Outdoor storage is not recommended for units that will be installed indoors. However, when outdoor storage is necessary, several things must be done to prevent damage:
Note: Keep the equipment on the original wooden blocks/ skid for protection and ease of handling.
· Select a well-drained area, preferably a concrete pad or blacktop surface.
· Place the unit on a dry surface or raised off the ground to assure adequate air circulation beneath the unit and to assure no portion of the unit will contact standing water at any time.
· Loosen the belt tension on the drive belts.
· Cover the unit securely with a canvas tarp.
· Do not stack units.
· Do not pile other material on the unit.
Long-Term Storage
For longer periods of storage, allow proper clearance around the unit to perform periodic inspections and maintenance on the equipment. While the unit is in storage:
· Every two weeks, rotate the fan and motor shaft 30 revolutions by hand. Check for free rotation.
· Every six months, check fan shaft bearings and grease lines. Add grease using a manual grease gun following the lubrications recommendations in “Fan Bearing Lubrication,” p. 148.
· 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.
Site Preparation
· Ensure the installation site can support the total weight of the unit (see “Dimensions and Weights,” p. 11 for approximate section weights; refer to the unit submittals for actual weights).
CLCH-SVX07R-EN

Pre-Installation
· Allow sufficient space for adequate free air and necessary service access (see “Service Clearance Recommendations,” p. 11). 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,” p. 95.

NOTICE Microbial Growth!
Failure to follow instructions below could result in odors and damage to the equipment and building materials. The floor or foundation must be level and the condensate drain at the proper height for proper drainage and condensate flow. Standing water and wet surfaces inside the equipment can become an amplification site for microbial growth (mold). If there is evidence of microbial growth on the interior insulation, it should be removed and replaced prior to operating the system.
· 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, 120 Vac power may need to be provided for the unit controller. Refer to submittals for more information. A dedicated 15-amp circuit is recommended.
· Wiring for the air handler must be provided by the installer and must comply with all national and local electrical codes.
· If the unit integral base frame ceiling suspension provisions are not used, the installer/contractor must provide a ceiling-suspended mounting frame designed to support the length, width, and weight of the entire airhandling unit. See “Ceiling Suspension,” p. 28 for more information.

Fans/Motors

Starter/VFD Weights

Note: Trane has a Precision MotorTM option for direct-drive plenum fans. This offering takes a general purpose motor and re-rates the motor for higher rated loads. This maximizes part-load motor efficiency and precisely sizes the motor for the application. To use these tables, the nameplate hp of the motor and the VFD–both of which will be greater than the Precision Motor hp–must be known.

With the exception of motorized impellers, fan weight does not include starter/VFD weight. See Table 7 for approximate starter/VFD weight.

Installation – Mechanical

NOTICE Equipment Damage!
Premature skid removal could result in 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.
Before preparing the unit for lifting, estimate the approximate center of gravity for lifting safety. Because of placement of internal components, the unit weight may be unevenly distributed, with more weight in the coil and fan areas. Approximate unit weights are provided in “Dimensions and Weights,” p. 11. Refer to the unit submittals for actual section weights. Test the unit for proper balance before lifting.
For outdoor air handlers, preparation of the roof curb or pier mount and roof openings must be completed before lifting to the roof. See CLCH-SVN04*-EN Roof Curbs for Performance Climate Changer Air Handlers installation instructions for details.
WARNING
Heavy Objects!
Failure to follow instructions below could result in unit dropping which could result in death or serious injury, and equipment or property-only damage. Ensure that all the lifting equipment used is properly rated for the weight of the unit being lifted. Each of the cables (chains or slings), hooks, and shackles used to lift the unit must be capable of supporting the entire weight of the unit. Lifting cables (chains or slings) may not be of the same length. Adjust as necessary for even unit lift.
Always rig sub-assemblies or sections as they ship from the factory. Never bolt sections together before rigging. To assist in proper placement, organize all ship splits in order of configuration before hoisting units in place. See Split to Split Orientation Instructions, p. 24.
· Make the loop of the sling parallel to the direction of airflow, if possible.
· When hoisting the unit into position, use the proper rigging method, such as straps, slings, spreader bars, or lifting lugs for protection and safety.
· Use all lifting lugs provided. See Figure 14 and Table 15 and Table 9 for lug hole sizes and location.

Forklifting Considerations

NOTICE Equipment Damage!
Improper use of fork lifts on units larger than size 30 could result in equipment damage. Do not use a fork lift on air handlers or subassemblies larger than size 30. 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 larger than size 30.
For unit sizes 3-30, a forklift may be used to lift a single section or small subassembly, provided the forks extend under both ends of the base frame, or as indicated in Figure 20. The forks should not contact the bottom of the air handler. Units should only be lifted from the proper end identified by the lifting label on the unit. A lifting crane or other means should be used for larger units where forks cannot extend under both base rails.

unit. Both the unit and the pipe cabinet should be supported by their base around the entire perimeter. See Figure 21 and Figure 22.
Figure 21. Piers located in each corner and spaced evenly every four feet

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

NOTICE Microbial Growth!
Failure to follow instructions below could result in odors and damage to the equipment and building materials. The floor or foundation must be level and the condensate drain at the proper height for proper drainage and condensate flow. Standing water and wet surfaces inside the equipment can become an amplification site for microbial growth (mold). If there is evidence of microbial growth on the interior insulation, it should be removed and replaced prior to operating the system.
If a unit arrives in sections, then each section must be individually hoisted, set on the housekeeping pad, roof curb, or pier mount and then assembled.
Refer to the unit submittals and unit tagging for correct placement of all sections. If there are any discrepancies between the submittals and the unit tagging, contact your local Trane representative before proceeding.
Following the order of the sections on the unit submittals and tagging, individually place each unassembled section or subassembly in the appropriate installation location.
Note: Prior to placing fan section in the appropriate installation location, verify shipping tie-downs have been removed.
For outdoor units, the pipe cabinet must also be mounted as an individual section. Refer to “Pipe Cabinet Installation,” p. 37 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
CLCH-SVX07R-EN

Piers Note: Piers beneath shipping splits must be structurally
sound to support the weight of the unit.
Figure 22. Side view with two shipping splits – locate one pier directly under each shipping split Shipping split
4 feet 4 feet 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. 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,” p. 61 for special assembly/ installation considerations.

Installation – Mechanical
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 24. Typical ceiling suspension-perpendicular channels

WARNING Risk of Unit Dropping!
Improper use of the mounting legs could result in unit dropping and crushing technicians which could result in death or serious injury, and equipment damage. 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. 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 ceilingsuspended mounting frame designed to support the length, width, and weight of the entire air-handling unit. See Dimensions and Weights, p. 11 for approximate weights. Note: It is the building engineer’s responsibility to size the
structural channels and to provide the appropriate hangers. Structural channels in a field-provided frame can be mounted parallel to airflow or perpendicular to airflow: · For parallel-to-airflow channels, size channels based on a four-point load distribution (see Figure 23). Figure 23. 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 24).
28

Using Integral Base Frame
Figure 25. Ceiling suspension for unit sizes 3-57
Hole diameter is 0.625 inches
If using the factory-provided integral base frame for ceiling suspension, individual sections and/or subassemblies will have base frame shipping splits and base frame lifting lugs. When using the base frame for ceiling suspension: · Suspend the unit (on both sides of the unit) at each
shipping split lug as well as the four corners of the unit (see Figure 25). See Figure 14 and Figure 15 and Table 9, p. 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 26) should be removed to simplify panel removal (except for hurricane units or units that require 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 gussets should be left in place for the lower
CLCH-SVX07R-EN

level unit unless they are installed in a shipping split that contains a coil. The other exception is when access to install or change out front-loaded filters is restricted or blocked.

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 yellow bag inside the fan section, access section, or mixing box.
The number of sections to be assembled often makes it necessary to use more than one section to ship the assembly material; therefore, check all sections thoroughly before contacting your Trane sales representative to report missing items.
Sections are joined with gasketing applied to one of the mating surfaces and hardware to bolt the sections together. The gasketing for section-to-section joints is a closed cell foam with adhesive backing.
To assemble the unit:
1. Locate the mounting hardware and gasket material.
2. All shipping supports and crating on the face of the sections must be removed and discarded to permit proper fit-up and sealing of the surfaces. Remove any shipping bolts located on the mounting surfaces of the sections (see Figure 28).

12. In addition, an adjustment can also be made to the height of the roof of either subassembly. At the center (widthwise) of the unit, measure the height of each adjacent subassembly and verify that the subassembly with the overlap sheet metal is higher than the mating subassembly roof. If it is not, adjust the height of either subassembly by loosening the screws in the vertical channels or component structure and adjust the height of the roof. See Figure 38 and Figure 39).

6. Wrap each connection individually with black electrical tape.
7. Fully wrap the connection with tape. 8. Use a bar clamp to pull adjacent shipping section lifting
lugs together. 9. For indoor units sizes 66-120 and for outdoor units size 35-
120, a wedge block is provided to aid in pulling and aligning the units together. Attach the wedge blocks to both sides of the units being pulled together, matching the correct wedge block with the correct hole pattern. See Figure 40, p. 33. 10. Verify that the subassembly with the overhang profile on the roof is higher than the mating subassembly. If it is not, raise one end of the subassembly and bring the unit together. See Figure 37. 11. Due to unlevel floor and platforms, the roof may be misaligned as shown in Figure 37. A common solution is to raise one end of the shipping section to clear the hemming before pulling the units together.

Dual-Path SDU/Winterizer Assembly
WARNING
Heavy Objects!
Stacking units without factory-approval and without factory-provided support brackets could result in the base unit collapsing under the weight of the top unit which could result in death or serious injury and property damage. Do not stack air handlers unless factory-designed and factory-approved. When stacking units, factory-designed unit support brackets must be used.
A dual-path, split dehumidification unit (SDU)/winterizer air handler consists of two units that are stacked together in a draw-thru arrangement that share one supply fan. The unit on the first level (primary unit) is designed to handle the return air and is larger than the unit on the second level (secondary unit), which is designed to handle outside air.

Factory-designed unit support brackets are provided with all factory-approved, dual-path SDUs or winterizer air handlers.
· A horizontal SDU/winterizer dual-path air handler incorporates a horizontal supply fan on the first level with a top opening in the primary unit that aligns with a bottom opening in the secondary unit.
· A vertical SDU/winterizer dual-path air handler incorporates a vertical supply fan on the second level with a back opening that aligns with a front opening in the secondary unit.
To assemble air handlers utilizing factory-approved and factory-provided dissimilar unit sizes for horizontal SDU or winterizer applications, join all similar size shipping sections per “Section-to-Section Assembly,” p. 29.
Horizontal SDU/Winterizer Assembly
To assemble dissimilar unit sizes for an indoor horizontal SDU/ winterizer configuration:
1. Locate the mounting hardware and gasket material.

CLCH-SVX07R-EN

Installation – Mechanical
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 65. The gasket needs to be placed such that it will be directly under the integral base frame of the secondary (smaller) unit to be stacked on top. The secondary unit will be centered along the width on the primary unit.

Anchoring

Lifting lugs should be used to anchor the unit at the ends of each shipping split. Per the anchor requirements, additional anchoring may be needed. If so, anchors will be provided and installed on the unit. An example of a seismic anchor is shown in Figure 72.
Anchor selection meets or exceeds IBC 2000,2003, 2006, 2009, 2012, and CBC 2007, 2010 compliance requirements.
Special Inspection per IBC Section 1704 is required on all installations. All anchors listed above must be installed to meet compliance.

Performance Climate Changer air handlers are approved and have has been designed to comply with the High Velocity Hurricane Zone of the Florida Building Code. Notice of compliance and additional product construction details can be found at the Miami-Dade County, Building Code Compliance Office Web site.
The Florida licensed engineer or architect-of-record for the project shall be responsible for the design, sizing, and structural adequacy of the product framework as well as curbing and attachment to the roof, or as accepted by the corresponding building departments.
Anchoring
The method shown in Figure 74 through Figure 78 is what is approved and recommended for anchoring the unit to substrate and roof curb. Any deviation to this may require the approval of the local building code enforcement agency.
Unit may be installed onto concrete (3.2 ksi min. compressive strength) or 1/4-inch thick steel (36 ksi min. yield) substrates with anchors through lifting lugs and angle clips attached to first level baserail. Unit may also be installed onto a 36 ksi yield steel curb by others.

4. Attach the unit base L angle from the pipe cabinet to the unit base rail. See Step 4 in Figure 86
5. Attach a U channel to the unit base L angle. Make sure to clear any coil piping. Make sure to attach enough nested U channels to comply to the unsupported span. See Step 5 in Figure 86.

6. Locate the pipe cabinet in place, and reinstall the U channel to the pipe base L angle and reinstall the top U channel to the nest (see Step 1, Figure 85).
7. When the L angle interferes with the unit base rail lifting lugs or splice plate, mark and cut L angle section to clear the component. If excess L angle is not needed for nested U channel, leave it off. See Figure 86.

Component Installation
The components in the air handler may have installation requirements that could affect the unit’s performance.
Dampers
Dampers are factory-installed and adjusted and can be found in mixing box. There are two damper blade configurations available: parallel-blade and opposed-blade.
TraqTM 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. The singe low-flow Traq damper will have a VCM. The economizing damper will not.
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 13.
Mixing section 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.
The economizer that meets or exceeds all mandatory requirements prescribed by Title 24, including but not limited to:
· 5-year parts only warranty
· Successfully tested to 60,000 actuations
· Less than 10 cfm/sq.ft. of damper leakage at one inch w.g. per AMCA 500L

Opposed-Blade/Parallel-Blade Damper
Opposed-blade and parallel-blade airfoil dampers in unit sizes 3-120, as well as internal and external face-and-bypass sections, have centered dampers with an internal jack-shaft (see Figure 89 and Figure 90). A 95-degree actuator rotation gives a 90-degree blade travel.
Note: Damper blades should be checked for proper operation from full open to full closed position before unit start up. Damper blade positioning may have changed due to shipping and handling vibrations.

Fans
The fan section can be configured as either draw-thru or blowthru. Review the submittals and unit tagging information prior to assembly to determine placement.

Diffusers
Diffuser sections are usually placed between a fan and a downstream coil or filter. Because placement is critical to unit performance, verify the correct placement of the diffuser section before assembling the unit.

WARNING
Hazardous Service Procedures!
Failure to follow all of the safety warnings provided, could result in death or serious injury. Technicians, in order to protect themselves from potential electrical, mechanical, and chemical hazards, MUST follow precautions in this manual and on the tags, stickers, and labels, as well as the following instructions: Unless specified otherwise, disconnect all electrical power including remote disconnect and discharge all energy storing devices such as capacitors before servicing. Follow proper lockout/tagout procedures to ensure the power can not be inadvertently energized. When necessary to work with live electrical components, have a qualified licensed electrician or other individual who has been trained in handling live electrical components perform these tasks.

Fan Isolation

The fan-and-motor assembly is internally isolated. The fan and motor bases are bolted to a minimum of four spring isolators. The isolators are secured to the fan section support base.
Shipping tie-down bolts are bolted adjacent to the isolators between the fan isolation base and the isolator support frame. The shipping tie-downs secure the isolation base to the support assembly to prevent any damage to the fan section during shipment.
Note: Remove the tie-downs only if the factory-provided isolation is to be used.

Adjusting the Isolators

Once the shipping tie-downs are removed and the internal isolation is released, it may be necessary to adjust the isolators to achieve the proper operation height of the fan and motor isolation base.
Minimum required clearances are listed in Table 28. 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.

Filters
Bag and cartridge filter sections can be used as a pre-filter section, a final filter section, or both. This use is determined by the filter’s placement in relation to the fan. · A final filter is placed after the fan. · A pre-filter is placed before the fan. Note: Cartridge and bag filters provided by Trane are fitted
with a 7/8-inch header that fits in the filter track. If using filters supplied by another manufacturer, filters should be purchased with a 7/8-inch header. In some cases it may be necessary to gasket other manufacturers’ filters to ensure a good air seal. Filters should be installed when the unit is set. This will protect internal components, such as the heating and cooling coils.
Final Filter Section
A final filter section should not be bolted directly to the face of a fan section. One or more intermediate sections must be placed between the fan discharge and the filter section.
Pre-Filter Section
A pre-filter section has no special installation requirements unless placed directly upstream of a plenum fan. In these configurations, ensure a blank section is placed between the fan inlet and the filter section. Trane recommends the use of disposable pre-filters with highefficiency filters. Disposable pre-filters slide into the mounting tracks just ahead of the bag/cartridge filters.

Filter Installation
WARNING Hazardous Voltage!
Failure to disconnect power before servicing could result in death or serious injury. Disconnect all electric power, including remote disconnects before servicing. Follow proper lockout/tagout procedures to ensure the power can not be inadvertently energized. Verify that no power is present with a voltmeter.
To install filters: 1. Disconnect the power to the unit. 2. Open the filter section access door. 3. Slide the filters into the tracks. Note: Bag filters must be installed with the pleats in the
vertical plane. 4. The block-off is permanently installed and will create a seal
when the access door is closed. 5. Close the access door slowly to allow any gasketing to
compress.
