Warnings, Cautions, and Notices
Safety advisories appear throughout this manual as required.Your personal safety and the proper operation of this machine depend upon the strict observance of these precautions.
The three types of advisories are defined as follows:
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 electrical codes.
WARNING
CAUTIONs
NOTICE
Indicates a potentially hazardous situation which, if not avoided, could result in death or serious injury.
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.
Indicates a situationthat could resultin equipment or property-damage only accidents.
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.
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.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
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.

The 140 - 500 ton Model RTAC unitsare helical-rotary type,
air-cooled liquid chillers designed for installation outdoors.The compressor circuits are completely assembled, hermetic packages that are factory-piped, wired, leak-tested, dehydrated, and tested for proper control operation before shipment.
Chilled water inlet and outlet openings are covered for shipment. Each compressor has a separate compressor motor starter.The RTAC series featuresTrane’s exclusive
Adaptive Control ™ logic, which monitors the control
variables that govern the operation of the chiller unit.
Adaptive Control logic can adjust capacity variables to
avoid chiller shutdown when necessary, and keep producing chilled water. The units feature two independent refrigerant circuits. Compressor unloaders are solenoid actuated and oil pressure operated. Each refrigerant circuit is provided with filter, sight glass, electronic expansion valve, and charging valves.The shell-and-tube type evaporator is manufactured in accordance with ASME standards or other international codes. Each evaporator is fully insulated and is equipped with water drain and vent connections. Packaged units have heat tape protection to - 20°F (-28.9°C) as standard.
As an option, a convenience outlet can be supplied.
Note: Packaged units are factory charged with refrigerant
and oil.

Pre-installation

Unit Inspection

When unit is delivered, verify it is the correct unit and is
properly equipped.
If unit is covered with optional tarp, confirm unit was ordered with a tarp. Inspect tarp for any visible damage.
If unit does not have optional tarp, compare information on 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 Checklist

To protect against loss due to damage in transit, complete
this checklist 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 repairunit until damage is inspected bythe carrier’s representative.
Install unit on a flat foundation, level (within 1/4” [6 mm] across the length and width of the unit), and strong enough to support unit loading.
Install unit per the instructions contained in the Installation-Mechanical and Installation-Electrical sections of this manual.
Install any optional sensors and make electrical connections at the CH530.
Where specified, provide and install valves in water piping upstream and downstream of evaporator water connections to isolate evaporator for maintenance, and to balance/trim system.
Furnish and install pressure gauges in inlet and outlet piping of the evaporator.
Furnish and install a drain valve to the bottom of the evaporator waterbox.
Supply and install a vent cock to the top of the evaporator waterbox.
Furnish and install strainers ahead of all pumps and automatic modulating valves, and at inlet of evaporator.
Provide and install field wiring.
Install heat tapeand insulate thechilledwater lines and any other portions of the system, as required, to prevent sweating under normal operating conditions or freezing during low ambient temperature conditions.
Install evaporator drain plug.The plug ships in unit control panel.
Start unit under supervision of a qualified service technician.

General

Report any damage incurred during handling or installation to theTrane sales office immediately.

Storage

Extended storage of outdoor unit prior to installation requires these precautionary measures:
Store the outdoor unit in a secure area.
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.
Close the discharge and liquid line isolation valves.

Installation Responsibilities

Generally, the contractor must do the following when installing an RTAC unit:

Dimensions and Weights

Dimensions

See unit submittals for specificunit dimensions and water connection locations.

Clearances

Provideenough space aroundthe outdoor unit to allowthe installation and maintenance personnel unrestricted
Figure 5. Recommended unit clearance — 15 foot bases
access to allservice points. Refer to submittal drawings for the unit dimensions. A minimum of 4 feet (1.2 m) is recommended for compressor service. Provide sufficient clearance for the opening of control panel doors. See
Figure 5, p. 21 through Figure 9, p. 23 for minimum
clearances. In all cases, local codes which require additional clearances will take precedence over these recommendations.

Unobstructed flow of condenser air is essential to maintain chiller capacity and operating efficiency. When determining unit placement, give careful consideration to assuring a sufficient flow of air across the condenser heat transfer surface.Two detrimental conditions are possible and must be avoided if optimum performance is to be achieved: warm air recirculation and coil starvation.
Warm air recirculationoccurs when discharge air from the
condenser fans is recycled back to the condenser coilinlet. Coil starvation occurs when free airflow to (or from) the condenser is restricted.
Both warm air recirculation and coil starvation cause reduction in unit efficiency and capacity due to the increased head pressures.
Debris, trash, supplies etc. should not be allowed to accumulate in the vicinity ofthe unit. Supply air movement may draw debris into the condenser coil, blocking spaces between coil fins and causing coil starvation. Special consideration should be given to low ambient units. Condenser coils and fan discharge must be kept free of snow or other obstructions to permit adequate airflow for satisfactory unit operation.
In situations where equipment must be installed with less clearance than recommended, such as frequently occurs in retrofit and rooftop applications, restricted airflow is common.The Main Processor will direct the unit to make as much chilled water aspossible given theactual installed conditions. Consult yourTrane sales engineer for more details.
Note: If the outdoor unit configuration requires a
variance to the clearance dimensions, contact your Trane Sales Office Representative. Also refer to Trane Engineering Bulletins for application
information on RTAC chillers.

Location Requirements

Noise Considerations

Locate outdoor unit away from sound sensitive areas. If required, install rubber vibration isolators in all water piping and use flexible electrical conduit. Consult an acoustical engineer for critical applications. Also refer to
Trane Engineering Bulletinsfor application informationon
RTAC chillers.

Foundation

A base or foundationis notrequired if unit location islevel
and strong enough to support unit’s operating weight as listed in “General Data,” p. 9, Table 1, p. 10 through
Table 10, p. 19. Provide rigid, non-warping mounting pads
or concrete foundation of sufficient strength and mass to support unit operating weight (including piping, and full operating charges of refrigerant, oil and water). Once in place, outdoor unit must be level within 1/ 4" (6 mm) over its length and width.
Trane Company is not responsible for equipment
problems resulting from an improperly designed or constructed foundation.
Note: To allow for cleaning under the condensing coil, it
is recommended that an opening be left between the unit base and the concrete pad.

Clearances

Provideenough space aroundthe outdoor unit to allowthe installation and maintenance personnel unrestricted access to allservice points. Referto submittal drawings for the unit dimensions. A minimum of 4 feet (1.2 m) is recommended for compressor service. Provide sufficient clearance for the opening of control panel doors. See
Figure 5, p. 21 through Figure 9, p. 23 in “Dimensions and
Weights,” p. 21 for minimum clearances. In all cases, local
codes which require additional clearances will take precedence over these recommendations.

Lifting Procedure

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
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 crushing operator/technician which could result in death or serious injury and possible equipment or property-only damage.
