WARNI NG

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 refrigerantsincluding industry replacements for CFCs such as HCFCs and HFCs.

Responsible Refrigerant Practices!

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

WARNI NG

Proper Field Wiring and Grounding Required!

All field wiring MUST be performed by qualified personnel. Improperly installed and grounded field wiring poses FIRE and ELECTROCUTION hazards. To avoid these hazards, you MUST follow requirements for field wiring installation and grounding as described in NEC and your local/state electrical codes. Failure to follow code could result in death or serious injury.

Overview of Manual

One copy of the appropriate service literature ships inside the control panel of each unit. The procedures discussed in this manual should only be performed by qualified, experienced HVAC technicians.

Note: Do not release refrigerant to the atmosphere! If

adding or removing refrigerant is required, the service technician must comply with all federal, state, and local laws.

This booklet describes the proper installation, startup, operation, and maintenance procedures for TC_, TE_, and YC_22.9 to 50 Ton CV (Constant Volume), VAV (Variable Air Volume), and SZ VAV (Single Zone Variable Air Volume) applications. Refer to the table of contents for a listing of specific topics. Refer to “Diagnostics,” p. 104 for troubleshooting information.

By carefully reviewing the information within this manual and following the instructions, the risk of improper operation and/or component damage will be minimized.

It is important that periodic maintenance be performed to help assure trouble free operation. A maintenance schedule is provided at the end of this manual. Should equipment failure occur, contact a qualified service organization with qualified, experienced HVAC technicians to properly diagnose and repair this equipment.

General Information

Precautionary Measures

WARN ING

Fiberglass Wool!

Product contains fiberglass wool. Disturbing the insulation in this product during installation, maintenance or repair will expose you to airborne particles of glass wool fibers and ceramic fibers known to the state of California to cause cancer through inhalation. You MUST wear all necessary Personal Protective Equipment (PPE) including gloves, eye protection, mask, long sleeves and pants when working with products containing fiberglass wool. Exposition to glass wool fibers without all necessary PPE equipment could result in cancer, respiratory, skin or eye irritation, which could result in death or serious injury.

- Avoid breathing fiberglass dust.

- Use a NIOSH approved dust/mist respirator.

- Avoid contact with the skin or eyes. Wear long-sleeved,

loose-fitting clothing, gloves, and eye protection.

- Wash clothes separately from other clothing: rinse

washer thoroughly.

- Operations such as sawing, blowing, tear-out, and

spraying may generate fiber concentrations requiring additional respiratory protection. Use the appropriate NIOSH approved respiration in these situations.

First Aid Measures

Eye Contact - Flush eyes with water to remove dust. If symptoms persist, seek medical attention.

Skin Contact - Wash affected areas gently with soap and warm water after handling.

An optional roof curb, specifically designed for the Voyager commercial rooftop units is available from Trane. The roof curb kit must be field assembled and installed according to the latest edition of the curb installation guide.

Unit Inspection

As soon as the unit arrives at the job site:

• Verify that the nameplate data corresponds to the sales order and bill of lading (including electrical data).

• Visually inspect the exterior of the unit, including the roof, for physical signs of shipping damage.

• Check for material shortages. Figure 11 , p. 18 illustrates where “ship with” items are placed inside the unit.

If the job site inspection reveals damage or material shortages, file a claim with the carrier immediately. Specify the type and extent of the damage on the “bill of lading” before signing. Do not install a damaged unit without the Appropriate Trane sales representative's approval!

• Visually check the internal components for shipping damage as soon as possible after delivery and before it is stored. Do not walk on the sheet metal base pans.

WARNI NG

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.

Bridging between the unit's main supports may consist of multiple 2 by 12 boards or sheet metal grating.

• If concealed damage is discovered, notify the carrier's terminal office immediately by phone and by mail. Concealed damage must be reported within 15 days.

• Request an immediate joint inspection of the damage by the carrier and the consignee. Do not remove the damaged material from the receiving location. Take photos of the damage, if possible. The owner must provide reasonable evidence that the damage did not occur after delivery.

Storage

Take precautions to prevent condensate formation inside the unit electrical components and motors when:

a. The unit is stored before it is installed; or,

b. The unit is set on the roof curb and temporary

auxiliary heat is provided in the building.

Isolate all side panel service entrances and base pan openings (e.g., conduit holes, S/A and R/A openings, and flue openings) to minimize ambient air from entering the unit until it is ready for startup.

Do not use the unit heater as temporary heat without completing the startup procedures detailed under

“Startup,” p. 38.

Trane will not assume responsibility for equipment damage resulting from accumulation of condensate on the unit electrical components.

12 RT-SVX34F-EN

Unit Dimensions and Weights

Recommended Clearances

Adequate clearance around and above each Voyager Commercial unit is required to ensure proper operation and to allow sufficient access for servicing.

If the unit installation is higher than the typical curb elevation, a field constructed catwalk around the unit is recommended to provide safe, easy access for maintenance and servicing. Table 1, p. 19 lists the recommended clearances for single and multiple unit installation. These clearances are necessary to assure adequate serviceability, cataloged capacities, and peak operating efficiency.

If the clearances available on the job site appear to be inadequate, review them with your Trane sales representative.

Roof Curb and Ductwork

The curbs for the 27.5 to 50 Ton commercial rooftop units enclose the entire unit base area. They are referred to as “full perimeter” type curbs.

Step-by-step instructions for the curb assembly and installation with curb dimensions and curb configuration for “A”, “B”, and “C” cabinets ship with each Trane accessory roof curb kit. (See the latest edition of the curb installation guide) Follow the instructions carefully to assure proper fit when the unit is set into place.

The S/A and R/A ductwork adjoining the roof curb must be fabricated and installed by the installing contractor before the unit is set into place. Trane curbs include flanges around the openings to accommodate duct attachment.

Ductwork installation recommendations are included in the instruction booklet that ships with each Trane accessory roof curb kit.

Note: For sound consideration, cut only the holes in the

roof deck for the supply and return duct penetration. Do Not remove the roof decking from the inside perimeter of the curb.

the unit into the ductwork. Refer to figures beginning on page 13 for the S/A and R/A opening dimensions.

All outdoor ductwork between the unit and the structure should be weather proofed after installation is completed.

If optional power exhaust is selected, an access door must be field-installed on the horizontal return ductwork to provide access to exhaust fan motors.

Figure 1. 60 Hz 27½-35, 50 Hz 23-29 Tons (TCD, TED,

YCD l ow heat)

If a Trane curb accessory kit is not used:

a. The ductwork can be attached directly to the S/A

and R/A openings. Be sure to use a flexible duct connector at the unit.

b. For “built-up” curbs supplied by others, gaskets

must be installed around the curb perimeter flange, Supply Air opening, and Return Air openings.

c. Insulation must be installed on the bottom of the

condenser section of the unit.

Horizontal Ductwork

When attaching the ductwork to a horizontal supply or horizontal return unit, provide a water tight flexible connector at the unit to prevent noise transmission from

Unit Rigging and Placement

WARN ING

Heavy Objects!

Ensure that all the lifting equipment used is properly rated for the weight of the unit being lifted. Each of the cables (chains or slings), hooks, and shackles used to lift the unit must be capable of supporting the entire weight of the unit. Lifting cables (chains or slings) may not be of the same length. Adjust as necessary for even unit lift. Other lifting arrangements could cause equipment or property damage. Failure to follow instructions above or properly lift unit could result in unit dropping and possibly crushing operator/ technician which could result in death or serious injury.

Use spreader bars as shown in the diagram. Refer to the Installation manual or nameplate for unit weight. Refer to the Installation instructions located inside the control panel for further rigging information.

1. Verify that the roof curb has the proper gaskets installed and is level and square to assure an adequate curb-to-unit seal.

The units must be as level as possible in order to assure proper condensate flow out of the unit. The maximum side-to-side and end-to-end slope allowable in any application is listed in Table 2, p. 19.

Installation General Requirements

Condensate Drain Connection

Each commercial rooftop unit is equipped with one (1) 11/4 inch Female PVC condensate drain connection.

Refer to Figure 11, p. 18 for the location of the connector. A condensate trap must be installed due to the drain connection being on the “negative pressure” side of the fan. Install a P-Trap at the unit using the guidelines in

Figure 14, p. 21.

Pitch the drain line at least 1/2 inch for every 10 feet of horizontal run to assure proper condensate flow.

Ensure that all condensate drain line installations comply with applicable building and waste disposal codes.

Figure 14. Condensate trap installation

4. Remove the dust cap from the tubing connector located below the sensor in the vertical support.

5. Attach one end of the 50' x 3/16” O.D. factory provided pneumatic tubing to the sensor's top port, and the other end of the tubing to the connector in the vertical support. Discard any excess tubing.

Units with Statitrac™

1. Open the filter access door, and locate the Statitrac Transducer Assembly illustrated in Figure 16, p. 22. There are two tube connectors mounted on the left of the solenoid and transducers. Connect one end of the field provided 1/4” (length 50-100 ft.) or 3/8” (length greater than 100 ft.) O.D. pneumatic tubing for the space pressurization control to the fitting indicated in the illustration.

2. Route the opposite end of the tubing to a suitable location inside the building. This location should be the largest open area that will not be affected by sudden static pressure changes.

Figure 15. Pressure tubing

O/A Sensor & Tubing Installation

An Outside Air Pressure Sensor is shipped with all units designed to operate on traditional variable air volume applications (non-SZ VAV) and units with Statitrac™.

A duct pressure transducer and the outside air sensor is used to control the discharge duct static pressure to within a customer-specified controlband. Refer to the illustration in Figure 15, p. 21 and the following steps to install the sensor and the pneumatic tubing.

1. Remove the O/A pressure sensor kit located inside the fan section. The kit contains the following items;

• an O/A static pressure sensor

• a sensor mounting bracket

• 50’ of 3/16” O.D. pneumatic tubing

• mounting hardware

2. Using two #10-32 x 1-3/4” screws provided, install the sensor's mounting bracket to the factory provided bracket (near the fan section).

3. Using the #10-32 x 1/2” screws provided, install the O/ A static pressure sensor vertically to the sensor bracket.

Disconnect Switch External Handle (Factory Mounted Option)

Units ordered with the factory mounted disconnect switch come equipped with an externally mounted handle. This allows the operator to disconnect power from the unit without having to open the control panel door. The handle location and its three positions are shown below;

ON - Indicates that the disconnect switch is closed, allowing the main power supply to be applied at the unit.

OFF - Indicates that the disconnect switch is open, interrupting the main power supply at the unit.

OPEN COVER/RESET - Turning the handle to this position releases the handle from the disconnect switch, allowing the control panel door to be opened.

WARNI NG

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.

Once the door has been opened, it can be closed with the handle in any one of the three positions outlined above, provided it matches the disconnect switch position. The handle can be locked in the “OFF” position. While holding the handle in the “OFF” position, push the spring loaded thumb key, attached to the handle, into the base slot. Place the lock shackle between the handle and the thumb key. This will prevent it from springing out of position.

Figure 17. Disconnect switch

An overall layout of the field required power wiring is illustrated in Figure 18, p. 24. To insure that the unit supply power wiring is properly sized and installed, follow the guidelines outlined below.

Note: All field installed wiring must conform to NEC

guidelines as well as State and Local codes.

Verify that the power supply available is compatible with the unit's name plate ratings for all components. The available power supply must be within 10% of the rated voltage stamped on the nameplate. Use only copper conductors to connect the 3-phase power supply to the unit.

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.

Main Power Wiring

WARNI NG

Proper Field Wiring and Grounding Required!

1. Table 7, p. 25 and Ta b le 10 , p . 2 6 list the electrical service sizing data. The electrical service must be protected from over current and short circuit conditions in accordance with NEC requirements. Protection devices must be sized according to the electrical data on the nameplate. Refer to “Electrical

Wire Sizing and Protection Device Equations” on page 27 for determining:

a. The appropriate electrical service wire size based

on “Minimum Circuit Ampacity” (MCA),

b. The “Maximum Over current Protection” (MOP)

device.

c. The “Recommended Dual Element fuse size” (RDE).

2. If the unit is not equipped with an optional factory installed Nonfused disconnect switch, a field supplied disconnect switch must be installed at or near the unit in accordance with the National Electrical Code (NEC latest edition). Refer to DSS calculations

Wire Sizing and Protection Device Equations” on page 27 for determining correct size.

Location for the electrical service entrance is shown in the unit dimensional drawings beginning with

Figure 1, p. 13. Complete the unit's power wiring

connections onto either the main terminal block HTB1,

or the factory mounted nonfused disconnect switch inside the unit control panel.

Note: When the factory installed through-the-base

option is not used, the installing contractor is required to seal any holes made in the base of the unit to prevent water from leaking into the building.

3. Provide proper grounding for the unit in accordance with local and national codes.

Figure 18. Typical field power wiring

Through-the-Base Electrical (Optional Accessory)

Liquid-tight conduit couplings are secured to the base of the unit for both power and control wiring. Liquid-tight conduit must be field installed between the couplings and the unit control box to prevent water leaks into the building.

Note: If the unit is set on the roof curb and temporary

auxiliary heat is provided in the building, it is recommended that the electrical and control wiring conduit opening in the control box be temporarily sealed to provide a vapor barrier.

Electrical Wire Sizing and Protection Device Equations

To correctly size the main power wiring based on MCA (Minimum Circuit Ampacity), use the appropriate equation listed below. Read the definitions that follow and then use Calculation #1 for determining MCA (Minimum Circuit Ampacity), MOP (Maximum Over current Protection), and RDE (Recommended Dual Element fuse size) for TC (Cooling Only) units and YC (Cooling with Gas Heat) units. Use Calculation #2 for TE (Cooling with Electric Heat) units.

Load Definitions:

• LOAD 1 = CURRENT OF THE LARGEST MOTOR (Compressor or Fan Motor)

• LOAD 2 = SUM OF THE CURRENTS OF ALL REMAINING MOTORS

• LOAD 3 = FLA (Full Load Amps) OF THE ELECTRIC HEATER

• LOAD 4 = ANY OTHER LOAD RATED AT 1 AMP OR MORE

• CRANKCASE HEATERS FOR HEATING MODE ONLY:

Calculation #1 - TC*, YC*-27.5 to 50 Ton Units

MCA = (1.25 x Load 1) + Load 2 + Load 4

MOP = (2.25 x Load 1) + Load 2 + Load 4 (See Note 1)

RDE = (1.5 x Load 1) + Load 2 + Load 4 (See Note 2)

Calculation # 2 - TE*-27.5 to 50 Ton Units

A. Single Source Power (all voltages)

To calculate the correct MCA (Minimum Circuit Ampacity), MOP (Maximum Over current Protection), and RDE (Recommended Dual Element fuse size), two (2) sets of calculations must be performed;

1. Calculate the MCA, MOP and/or RDE values using the above equation as if the unit is operating in the cooling mode.

2. Calculate the MCA, MOP and/or RDE values as if the unit is operating in the heating mode, as follows:

Note: When determining loads, the compressors and

condenser fan motors do not operate during the heating cycle.

Units with less than 50 KW Heaters

MCA = 1.25 x (Load 1 + Load 2 + Load 4) + (1.25 x Load 3)

Units with 50 KW or Larger Heaters

MCA = 1.25 x (Load 1 + Load 2 + Load 4) + Load 3

The MCA value stamped on the nameplate is the largest of the two calculated values.

MOP = (2.25 x Load 1) + Load 2 + Load 3 + Load 4 (See Note

The MOP value stamped on the nameplate is the largest of the two calculated values.

RDE = (1.5 x Load 1) + Load 2 + Load 3 + Load 4 (See Note 2)

Note: Select an over current protection device equal to

the MOP value. If the calculated MOP value does not equal a standard size protection device listed in NEC 240-6, select the next lower over current protection device. If the calculated MOP value is less than the MCA value, select the lowest over current protection device which is equal to or larger than the MCA, providing the selected over current device does not exceed 800 amps.

Note: Select a Dual Element Fuse equal to the RDE value.

If the calculated RDE value does not equal a standard dual element fuse size listed in NEC 2406, select the next higher fuse size. If the calculated RDE value is greater than the MOP value, select a Dual Element fuse equal to the calculated MOP (Maximum Over current Protection) value

An overall layout of the various control options available for a Constant Volume application is illustrated in

Figure 19, p. 30 and Figure 20, p. 31 illustrates the various

control options for a Variable Air Volume application. The required number of conductors for each control device are listed in the illustration.

A typical field connection diagram for the sensors and other options are shown in the following section “Remote Panels and Sensors”. These diagrams are representative of standard applications and are provided for general reference only. Always refer to the wiring diagram that shipped with the unit for specific electrical schematic and connection information.

Note: All field wiring must conform to NEC guidelines as

well as state and local codes.

Control Power Transformer

WARN ING

Hazardous Voltage!

The 24 volt control power transformers are equipped with internal circuit breakers. They are to be used only with the accessories called out in this manual. If a circuit breaker trips, be sure to turn off all power to the unit before attempting to reset it.

On units equipped with the VFD option, an additional control power transformer is used. The secondary is protected with fuses. Should the fuse blow, be sure to turn off all power to the unit before attempting to replace it.

Field Installed AC Control Wiring

WARNI NG

Proper Field Wiring and Grounding Required!

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.

Before installing any connecting wiring, refer to Tab l e 13 ,

p. 28 for conductor sizing guidelines and;

• Use copper conductors unless otherwise specified.

• Ensure that the AC control voltage wiring between

the controls and the unit's termination point does not exceed three (3) ohms/conductor for the length of the run.

Note: Resistance in excess of 3 ohms per conductor may

cause component failure due to insufficient AC voltage supply.

• Refer to dimensional information beginning with

Figure 1, p. 13 for the electrical access locations

provided on the unit.

• Do not run the AC low voltage wiring in the same

conduit with the high voltage power supply wiring.

Be sure to check all loads and conductors for grounds, shorts, and miswiring. After correcting any discrepancies, reset the circuit breakers by pressing the black button located on the left side of the transformer.
