Important Environmental Concerns!

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

Responsible Refrigerant Practices!

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

ATTENTION: Warnings, Cautions and Notices appear at appropriate sections throughout this literature. Read these carefully:

WARNING

Indicates a potentially hazardous situation which, if not avoided, could result in death or serious injury.

CAUTIONs Indicates a potentially hazardous situation which, if not avoided, could result in minor or moderate injury. It could also be used to alert against unsafe practices.

NOTICE:

General Information

Unit Inspection

As soon as the unit arrives at the job site

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

• Verify that the power supply complies with the unit nameplate specifications.

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

• Check for material shortages. Refer to the Component Layout and Ship with Location illustration.

Important: If the job site inspection of the unit 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.

• Visually inspect 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.

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 of damage 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 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.

• Notify the appropriate Trane office before installing or repairing a damaged unit.

Unit Nameplate

One Mylar unit nameplate is located on the outside upper right corner of the control panel door. It includes the unit model number, serial number, electrical characteristics, weight, refrigerant charge, as well as other pertinent unit data. A small metal nameplate with the Model Number, Serial Number, and Unit Weight is located just above the Mylar nameplate, and a third nameplate is located on the inside of the control panel door.

When ordering replacement parts or requesting service, be sure to refer to the specific model number, serial number, and DL number (if applicable) stamped on the unit nameplate.

Compressor Nameplate

The nameplate for the “Scroll” compressors is located on the compressor lower housing.

EVP Chiller - Applications Only

If ordered with remote EVP chiller kit, piping components ship in condenser section. The heat exchanger ships separately. The 20-30 chiller nameplate is located on same side as water connections near center left. The 40-120 Ton chiller nameplate is located on same side as water connections near bottom. To view, raise insulation flap over nameplate. Replace and retape insulation flap after viewing.

Phase Monitor (1U3)

The unit is equipped with a phase monitor in the control box. The phase monitor will protect against phase loss, imbalance and reversal of the line voltage. If a fault occurs, the red LED will energize. While the fault condition is present the phase monitor interrupts the 115V control circuit. If no faults are observed, a green LED will be energized.

Manual Motor Protectors (380V through 575V

Only): Manual motor protectors will be used as branch circuit protection for compressors. These devices are capable of providing both overload and short-circuit protection.

Before operating, the manual motor protector must be switched with the rotary on/off switch to the “ON” position and the overload setpoint dial must be set to the appropriate rating of the motor.

Important: In order to avoid nuisance trips, the overload setpoint dial must be adjusted to the following calculated value:

• Overload Setting = (Compressor RLA) x 1.12

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.

Figure 1. Compressor protection module

SS-SVX11H-EN 7

On 80-120 Ton units, the CSHN*** compressors come equipped with a compressor protection device capable of detecting phase reversal, phase loss, and phase unbalance. The compressor protection device uses a Green and Red LED to indicate the compressor status. A solid Green LED denotes a fault free condition; a blinking Red LED indicates an identifiable fault condition. Once a problem has been detected, the power will have to be cycled to clear the reset circuit.

Note: If the compressor has tripped, the resistance will be 4500 ohms or greater; when reset, they will be less than 2750 ohms.

Blink Code: The blink code consists of different on / off time of the Red LED which is repeated continuously until either the fault is cleared or until power is cycled.

Discharge Line Thermostat

The first compressor on each circuit is equipped with a Discharge Line Thermostat. If the temperature of the line exceeds 230F the thermostat interrupts the 115V control circuit for the compressors and all the compressors on the circuit will de-energize. Once the temperature drops below 180F the thermostat will close and allow the compressor to be energized.

Unit Description

All air cooled condensing units are designed for outdoor installations with vertical air discharge. These units may be installed on a flat roof or placed on a concrete slab at ground level.

Before shipment, each unit is leak-tested, evacuated, a nitrogen holding charge is added, and the controls are tested for proper operation.

The condenser coils an all Aluminum Microchannel design. Corrosion protected condenser coils are a standard option. Louvered condenser grilles for coil protection are standard. Direct-drive, vertical discharge condenser fans are provided with built-in current and overload protection.

For “Ship with” items, see Figure 2, p. 9 and Figure 3, p. 9.

If low ambient operation is required, low ambient dampers are available as a field or factory installed option.

Units may be ordered with one of the following options:

• No System Controls (Field provided controls required)

• Constant Volume Controls

Unit Dimensions & Weights

Unit Clearances

Figure 4, p. 10 illustrates the minimum operating and service clearances for either a single, multiple, or pit application. These clearances are the minimum distances necessary to assure adequate serviceability, cataloged unit capacity, and peak operating efficiency.

Locate the unit as close to the applicable system support equipment as possible to minimize refrigerant piping lengths.

Allow adequate clearance for water and refrigerant piping connections, space to perform service procedures, i.e.

read gauges, thermometers, and operate water system valves.

EVP Chiller Considerations

Allow adequate clearance for water and refrigerant piping connections, space to perform service procedures, (i.e.

read gauges, thermometers, and operate water system valves.

Note: The braze plate chiller is intended for indoor application. If a sub-freezing location is required, contact Trane for installation precautions required to prevent damage.

NOTICE:

Equipment Damage!

Providing less than the recommended clearances could result in condenser coil starvation or recirculation of hot condenser air.

Use spreader bars as shown in Figure 25. See installation manual or nameplate for unit weight. See installation instructions located inside the central panel for further rigging information.

A Rigging illustration and Center-of-Gravity dimensional data table is shown in Figure 25. Refer to the typical unit operating weights table before proceeding.

1. Rig the condensing unit as shown in Figure 25. Attach adequate strength lifting slings to all four lifting brackets in the unit base rail. Do not use cables, chains, or slings except as shown.

2. Install spreader bars, as shown in Figure 25, to protect the unit and to facilitate a uniform lift. The minimum distance between the lifting hook and the top of the unit should be 7 feet.

3. Test-lift the unit to ensure it is properly rigged and balanced, make any necessary rigging adjustments.

4. Lift the unit and position it into place.

WARNING

Heavy Objects!

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

NOTICE:

Heat Exchanger or Compressor Damage!

Do not operate system below minimum specified water flow rate or below 42°F leaving water temperature without glycol. If water freezes inside the brazed plate heat exchanger, separation between refrigerant and water could be damaged and the heat exchanger must be replaced. Compressor damage could also occur requiring replacement and system cleanup.

Unit Isolation

To minimize unit sound and vibration transmission, one of the following installation methods should be used:

1. Install the unit directly on an isolated (detached) concrete pad or on isolated concrete footings located at each unit load point.

2. Install the optional neoprene or spring isolators at each . Refer to the “Neoprene isolators” or “Spring isolator” section below.

Neoprene Isolators (20 - 60 Ton units)

Install the neoprene isolators at each unit mounting (load) point, using the following procedure:

1. Elevate the unit (one side at a time) to allow access to the base rail mounting holes.

2. Align the mounting holes in the base rail of the unit with the holes in the top of the appropriate isolator. See Table 6, p. 33 and/or Table 7, p. 33 for the appropriate isolator for each load point.

3. Install a 1/2" NC bolt (field supplied) through the base rail of the unit into the threaded bolt hole of the isolator. Position the isolator to allow access to the mounting holes in the base of the isolator, then tighten securely.

4. Lower the unit and isolator onto the mounting surface.

The maximum isolator deflection should be approximately 1/4 inch.

5. Secure the isolator to the mounting surface using the base holes in the isolator.

6. Level the unit carefully. Refer to the “Leveling the Unit” section.

7. After the unit is level, tighten the isolator base mounting bolts to secure them to the mounting surface.

Spring Isolators (20 - 120 Ton units)

Install the spring isolators at each unit mounting (load) point, using the following procedure:

1. Elevate the unit (one side at a time) to allow access to the base rail mounting holes.

2. Align the mounting holes in the base rail of the unit with the positioning pin in the top of the appropriate isolator. Refer to Figure 26, p. 33 for the appropriate isolator for each load point.

3. Position the isolator to allow access to the mounting holes in the base of the isolator.

4. Lower the unit onto the isolator. The positioning pin on the isolator must engage into the hole of the base rail.

The clearance between the upper and lower isolator housings should be approximately 1/4 to 1/2 inch.

Refer to Figure 26, p. 33 A clearance greater than 1/2 inch indicates that shims are required to level the unit.

Refer to the “Leveling the Unit” section.

5. Make minor clearance adjustments by turning the isolator leveling bolt (Figure 26, p. 33) clockwise to increase the clearance and counterclockwise to decrease the clearance. If proper isolator clearance cannot be obtained by turning the leveling bolt, level the isolators themselves. A 1/4 inch variance in elevation is acceptable.

6. Secure the isolator to the mounting surface using the base holes in the isolator.

7. After unit is level, tighten isolator base mounting bolts to secure them to the mounting surface.

WARNING

Heavy Objects!

Use solid type blocks, i.e. 4" X 4" wood blocks or similar material to prevent collapsing. Keep hands and other body limbs clear of elevated base rail while installing isolators. Failure to do so could result in death or serious injury.

Installation

Foundation

If the unit is installed at ground level, elevate it above the snow line. Provide concrete footings at each support location or a slab foundation for support. See Table 3, p. 30 for the unit operating and point loading weights when constructing the footing foundation.

Anchor the unit to the footings or slab using hold down bolts or isolators. Isolators should be installed to minimize the transmission of vibrations into the building. See section “Unit Isolation,” p. 32 for spring or rubber isolator installation instructions.

For rooftop applications, ensure the roof is strong enough to support the unit. See Table 3, p. 30 for the unit operating weights.

Anchor the unit to the roof with hold-down bolts or isolators. Follow the instructions in section “Unit Isolation,” p. 32 “for proper isolator placement and installation.

Check with a roofing contractor for proper waterproofing procedures.

Unit Isolation

To minimize unit sound and vibration transmission, one of the following installation methods should be used:

1. Install the unit directly on an isolated (detached) concrete pad or on isolated concrete footings located at each unit load point.

2. Install the optional neoprene or spring isolators at each mounting location. See “Neoprene Isolators (20 - 60 Ton units),” p. 32 or “Spring Isolators (20 - 120 Ton units),” p. 32.

Leveling the Unit

Before tightening the mounting bolts, level the unit carefully.
