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.

WARNING

Refrigerant under High Pressure!

System contains oil and refrigerant under high pressure. Recover refrigerant to relieve pressure before opening the system. See unit nameplate for refrigerant type. Do not use non-approved refrigerants, refrigerant substitutes, or refrigerant additives. Failure to recover refrigerant to relieve pressure or the use of nonapproved refrigerants, refrigerant substitutes, or refrigerant additives could result in an explosion which could result in death or serious injury or equipment damage.

WARNING

Personal Protective Equipment (PPE) Required!

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

• Before installing/servicing this unit, technicians MUST put on all 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).

ALWAYS refer to appropriate Material Safety Data

Sheets (MSDS)/Safety Data Sheets (SDS) and OSHA guidelines for proper PPE.

• When working with or around hazardous chemicals,

ALWAYS refer to the appropriate MSDS/SDS and

OSHA/GHS (Global Harmonized System of Classification and Labelling of Chemicals) guidelines for information on allowable personal exposure levels, proper respiratory protection and handling instructions.

• If there is a risk of energized electrical contact, arc, or flash, technicians MUST put on all PPE in accordance with OSHA, NFPA 70E, or other country-specific requirements for arc flash protection, PRIOR to servicing the unit. NEVER PERFORM ANY SWITCHING, DISCONNECTING, OR VOLTAGE

TESTING WITHOUT PROPER ELECTRICAL PPE AND ARC FLASH CLOTHING. ENSURE ELECTRICAL

METERS AND EQUIPMENT ARE PROPERLY RATED FOR INTENDED VOLTAGE.

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

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 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.

Pre-Installation

Unit Inspection

When unit is delivered, verify it is the correct unit and is

properly equipped. Compare information on the unit nameplate with ordering and submittal information. Inspect all exterior components for visible damage.Report any apparent damage or material shortage to carrier and make a “unit damage” notation on carrier’s delivery receipt. Specify extent and type of damage found and notifyTrane Sales Office. Do not proceed with installation of a damaged unit without sales office approval.

Inspection

To protect against loss due to damage in transit, complete

the following steps upon receipt of unit.

• Inspect the individual pieces of the shipment before

accepting the unit. Check for obvious damage to the unit or packing material.

• Inspect the unit for concealed damage as soon as

possible after delivery and before it is stored. Concealed damage must be reported within 15 days.

• If concealed damage is discovered, stop unpacking the

shipment. 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 carrier’s terminal of the damage

immediately, by phone and by mail. Request an immediate, joint inspection of the damage with the carrier and the consignee.

NotifyTrane sales representative and arrange for repair. Do not repair unituntil damage is inspectedby the carrier’s representative.

Storage

Extended storage of outdoor unit prior to installation requires these precautionary measures:

• Store the outdoor unit in a secure area.

• For units that have been charged with refrigerant, verify the following valves are closed on each circuit:

• Suction service valve (butterfly valve)

• Liquid line angle valve or EXV (EXV is driven closed

whenever circuit is powered)

• Oil line shutoff valves to brazed plate heat

exchangers

Note: Units with factory refrigerant charge (model

number digit 15 = 1) are shipped with suction, liquid and oil line shutoff valves closed, isolating most of refrigerant charge in the evaporator. If unit goes directly into long term storage, it is recommended that these valve positions be confirmed.

• For units with nitrogen charge option (model number digit 15 = 2), units are shipped with valves open. If unit goes directly into storage prior to refrigerant charge, confirm all service valves are open.

• At least every three months (quarterly), check the pressure in the refrigerant circuits to verify that the refrigerant charge is intact. If it is not, contact a qualified service organization and the appropriate

Trane sales office.

Location Requirements

Sound Considerations

• Refer toTrane Engineering Bulletin Chiller Sound Ratings and Installation Guide RLC-PRB035-EN for

sound consideration applications.

• Locate the unit away from sound-sensitive areas.

• Install the optional elastomeric isolators under the unit. See

• Chilled water piping should not besupported by chiller frame.

• Install rubber vibration isolators in all water piping.

• Use flexible electrical conduit.

• Seal all wall penetrations.

Note: Consult an acoustical engineer for critical

Foundation

Provide rigid, non-warping mounting pads or a concrete foundation of sufficient strength and mass to support the applicable operating weight (i.e., including completed piping, and full operating charges of refrigerant, oil and water). See Table 5, p. 14 for unit operating weights. Once in place, the unit must be level within 1/4”(6.4 mm) across the length and width of the unit.TheTrane Company is not responsible for equipment problems resulting from an improperly designed or constructed foundation.

applications.

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.

WARNING

Proper Lifting Configuration Required!

Use only lift locations designated with label shown in

Figure 6. Do NOT use locations marked with label

shown in Figure 7. Use unit lifting configurations as shown in Table 6 and Figure 8, p. 16 thru Figure 10,

p. 17. Other lifting arrangements could result in death,

serious injury or equipment damage.

Figure 6. Label - lift location

Clearances

Provide enough space around the unit to allow the installation and maintenance personnel unrestricted access to all service points. See submittal drawingsfor the unit dimensions, to provide sufficient clearance for the opening of control panel doors and unit service. See

Figure 5, p. 14 for minimum clearances. In all cases, local

codes which require additional clearances will take precedence over these recommendations.

For close spacing information, see RLC-PRB037-EN.

Isolation and Sound Emission

The most effective form of isolation is to locate the unit

away from any sound sensitive area. Structurally transmitted sound can be reduced by elastomeric vibration eliminators. Spring isolators are not recommended. Consult an acoustical engineer in critical sound applications.

For maximum isolation effect, isolate water lines and electrical conduit.Wall sleeves and rubber isolated piping hangers can be used to reduce the sound transmitted through water piping.To reduce the sound transmitted through electrical conduit, use flexible electrical conduit.

State and local codes on sound emissions should always be considered. Since the environment in which a sound source is located affects sound pressure, unit placement must be carefully evaluated. Sound power levels for Stealth chillers are available on request.

Unit Isolation and Leveling

For additional reduction of sound and vibration, install the optional elastomeric isolators.

Construct an isolated concrete pad for the unit or provide concrete footings at the unit mounting points. Mount the unit directly to the concrete pads or footings.

Level the unit using the base rail as a reference.The unit must be level within 1/4-in (6 mm) over the entire length and width. Use shims as necessary to level the unit.

Elastomeric Isolators (Optional for units without seismic rating)

Note: See unit submittal, or Table 11, p. 21 thru Table 13,

p. 23 for point weights, isolator location and

isolator selections.

1. Secure the isolators to the mounting surface using the mounting slots in the isolator base plate. Do not fully tighten the isolator mounting bolts at this time.

2. Align the mounting holes in the base of the unit with the threaded positioning pins on the top of the isolators.

3. Lower the unit onto the isolators and secure the isolator to the unit with a nut.

4. Level the unit carefully. Fully tighten the isolator mounting bolts.

Proper Water Treatment!

The use of untreated or improperly treated water could

result in scaling, erosion, corrosion, algae or slime. It is recommended that the services of a qualified water treatment specialist be engaged to determine what water treatment, if any, is required. Trane assumes no responsibility for equipment failures which result from untreated or improperly treated water, or saline or brackish water.

Components and layout will vary slightly, depending on the location of connections and the water source.

A vent is provided on the top of the evaporator at the chilled water inlet. Be sure to provide additional vents at high points in the piping to bleed air from the chilled water system. Install necessary pressure gauges to monitor the entering and leaving chilled water pressures.

Provide shutoff valves in lines to the gauges to isolate

NOTICE:

Evaporator Damage!

The chilled water connections to the evaporator are to

be “victaulic” type connections. Do not attempt to weld these connections, as the heat generated from welding can cause microscopic and macroscopic fractures on the cast iron waterboxes that can lead to premature failure of the waterbox. To prevent damage to chilled water components, do not allow evaporator pressure (maximum working pressure) to exceed 150

them from the system when they are not in use. Use rubber vibration eliminators to prevent vibration transmission through the water lines.

If desired, install thermometers in the lines to monitor entering and leaving water temperatures. Install a balancing valve in the leaving water line to control water flow balance. Install shutoff valves on both the entering and leaving water lines so that the evaporator can be isolated for service

Pressure Relief Valves

NOTICE:

Evaporator Damage!

To prevent shell damage, install pressure relief valves in

the evaporator water system.

Install a water pressure relief valve in the evaporator inlet piping between the evaporator and the inlet shutoff valve, as shown in Figure 17, p. 25. Water vessels with close- coupled shutoff valves have a high potential for hydrostatic pressure buildup on a water temperature increase. Refer to applicable codes for relief valve installation guidelines.

Evaporator Flow Switch

NOTICE:

Equipment Damage!

Flow switch is on a 24V circuit. Do NOT apply 120V to the flow switch. Incorrect voltage application could cause damage to the flow switch.

The flow switch is factory-installed and programmed

based on the operating conditions submitted with the order.The leaving evaporator temperature, fluid type and fluid concentration affect the selected flow switch. If the operating conditions on the job site change, the flow switch may need to be replaced. Contact your localTrane Sales office for more information.

The sensor head includes 3 LEDs, two yellow and one

green.Wait 15 seconds after poweris applied to the sensor before evaluating LEDs for flow status. When wired correctly and flow is established, only the green LED should be lit. Following are the LED indicators:

• Green ON, both yellow OFF — Flow

• Green and outside yellow ON — No Flow

• Center yellow ON continuously — Miswire

Factory installed jumper wire W11 must be removed if using auxiliary contacts and/or additional proof of flow. See schematics in RTAE-SVE01*-EN for more details.

Indexing Flow Switch

To properly index the flow switch, the following

requirements must be met:

• The dot must be at a position no greater than 90° off Index.

• The torque must be between 22 ft-lb minimum and 74 ft-lb maximum.

• A minimum distance of 5x pipe diameter must be maintained between flow switch and any bends, valves, changes in cross sections, etc.

• Install heat tape on all water piping, pumps, and other components that may be damaged if exposed to freezing temperatures. Heat tape must be designed for low ambient temperature applications. Heat tape selection should be based on the lowest expected ambient temperature.

• Tracer™ UC800 controller can start the pump when freezing conditions are detected. For this option the pump must to be controlled by the Stealth unit and this function must be validated.

• Water circuit valves need to stay open at all times.

• Water pump control and heater combination will protect the evaporator down to any

ambient temperature provided power is available to the pump and the controller. This option will NOT protect the evaporator in the event of a power failure to the chiller unless backup power is supplied to the necessary components.

• When no chiller operation is possible and the pump is already off, UC800 pump control for freeze protection will command the pump to turn: ON if average of the evaporator entering water temperature, the evaporator leaving water temperature, and the evaporator refrigerant pool temperature is less than Low Evaporator Refrigerant Temperature Cutout (LERTC) + 4°F for a period of time. OFF again if the evaporator refrigerant pool temperature rises above the LERTC + 6°F for a period of time.

Note: Time period referenced for ON and Off conditions above is dependent on past running conditions and present temperatures measured.

ON if entering OR leaving water temperature< LWTC for 30°F-sec (17°C-sec) OFF again if water temperature > LWTC for 30 min

• Freeze protection can be accomplished by adding sufficient glycol to protect against freezing below the lowest ambient expected.

• Use of glycol type antifreeze reduces the cooling capacity of the unit and must be considered in the design of the system specifications.

• Shut off the power supply to the unit and to all heaters.

• Purge the water circuit.

• Blow out the evaporator to ensure no liquid is left in the evaporator.

NOTICE:

Evaporator Damage!

If insufficient concentration or no glycol is used, the evaporator water flow must be controlled by the UC800

AND heaters must be used to avoid catastrophic

damage to the evaporator due to freezing. It is the responsibility of the installing contractor and/or the customer to ensure that a pump will start when called upon by the chiller controls. Refer to RLC-PRB012-EN. Even with water pump control, a power loss of as little as 15 minutes under freezing conditions can damage the evaporator. Only the proper addition of freeze inhibitor or complete drainage of the water circuit can ensure no evaporator damage in the event of a power failure.
