CAUTION: Indicates a situation that may result in equipment or propertydamage 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 and 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
Contains Refrigerant!
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 follow proper procedures or the use of non-approved refrigerants, refrigerant substitutes, or refrigerant additives could result in death or serious injury or equipment damage.

General information
When the unit is delivered, verify that it is the correct unit and that it is properly equipped. Compare the information which appears on the unit nameplate with the ordering and submittal information.
Inspect all exterior components for visible damage. Report any apparent damage or material shortage to the carrier and make a “unit damage” notation on the carrier’s delivery receipt. Specify the extent and type of damage found and notify the appropriate Trane Sales Office. Do not proceed with installation of a damaged unit without sales office approval.
To protect against loss due to damage incurred in transit, complete the following checklist upon receipt of the 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.
•Notify the Trane sales representative and arrange for repair. Do not repair the unit, however, until damage is inspected by the carrier’s representative.
Check all the accessories and loose parts which are shipped with the unit against the shipping list. Included in these items will be water vessel drain plugs, rigging and electrical diagrams, and service literature, which are placed inside the control panel and/or starter panel for shipment.
The 140 - 500 ton Model RTAC units are 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.
NOTE: Packaged units are factory charged with refrigerant and oil.
Figure 2 shows a typical RTAC packaged unit and its components.
Table 1 through Table 5 contain general RTAC mechanical specifications for all unit sizes.

RTAC-SVX01F-EN |
General Information
.
Chilled water inlet and outlet openings are covered for shipment. Each compressor has a separate compressor motor starter. The RTAC series features Trane’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.

Installation - Mechanical
Generally, the contractor must do the following when installing an RTAC unit:
•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 the evaporator for maintenance, and to balance/trim system.
•Furnish and install flow switch to prove chilled water flow.
•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 tape and insulate the chilled water 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.
The RTAC outdoor unit nameplates (Figure 1) are applied to the exterior of the Control Panel. A compressor nameplate is located on each compressor.
The outdoor unit nameplate provides the following information:
–Unit model and size description.
–Unit serial number.
–Identifies unit electrical requirements.
–Lists correct operating charges of R-134a and refrigerant oil (Trane OIL00048).
–Lists unit test pressures.
–Identifies installation, operation and maintenance and service data literature (Pueblo).
–Lists drawing numbers for unit wiring diagrams (Pueblo).
The compressor nameplate provides following information:
–Compressor model number.
–Compressor serial number.
–Compressor electrical characteristics.
–Utilization range.
–Recommended refrigerant.

Installation - Mechanical
Extended storage of the outdoor unit prior to installation requires the following precautionary measures:
1.Store the outdoor unit in a secure area.
2.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.
3.Close the discharge and liquid line isolation valves.
Report any damage incurred during handling or installation to the Trane sales office immediately.
A base or foundation is not required if the selected unit location is level and strong enough to support the unit’s operating weight as listed in Table 1 through Table 5 in the General Information section.
See Table 6 for lifting weights and center of gravity (CG) dimensions.
1.Lifting chains/cables will not
be the same length. Adjust to keep unit level while lifting.
2.Do not fork lift unit.
3.Weights are typical for units with R-134a charge.
