Warranty
Warranty is based on the general terms and conditions of the manufacturer. The warranty is void if the equipment is repaired or modified without the written approval of the manufacturer, if the operating limits are exceeded or if the control system or the electrical wiring is modified. Damage due to misuse, lack of maintenance or failure to comply with the manufacturer's instructions or recommendations is not covered by the warranty obligation. If the user does not conform to the rules of this manual, it may entail cancellation of warranty and liabilities by the manufacturer.
Refrigerant
The refrigerant provided by the manufacturer meets all the requirements of our units. When using recycled or reprocessed refrigerant, it is advisable to ensure its quality is equivalent to that of a new refrigerant. For this, it is necessary to have a precise analysis made by a specialized laboratory. If this condition is not respected, the manufacturer warranty could be cancelled.
Maintenance contract
It is strongly recommended that you sign a maintenance contract with your local Service Agency. This contract provides regular maintenance of your installation by a specialist in our equipment. Regular maintenance ensures that any malfunction is detected and corrected in good time and minimizes the possibility that serious damage will occur. Finally, regular maintenance ensures the maximum operating life of your equipment. We would remind you that failure to respect these installation and maintenance instructions may result in immediate cancellation of the warranty.
Training
To assist you in obtaining the best use of it and maintaining it in perfect operating condition over a long period of time, the manufacturer has at your disposal a refrigeration and air conditioning service school. The principal aim of this is to give operators and technicians a better knowledge of the equipment they are using, or that is under their charge. Emphasis is particularly given to the importance of periodic checks on the unit operating parameters as well as on preventive maintenance, which reduces the cost of owning the unit by avoiding serious and costly breakdown.

Location Requirements
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 Trane air-cooled RTAD chillers are available on request.
For additional reduction of sound and vibration, install the optional neoprene 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. Use shims as necessary to level the unit.
Neoprene Isolator (optional) Installation
Refer to submittals for diagrams. 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. Maximum isolator deflection should be 1/4 inch (6 mm).
4 Level the unit carefully. Fully
tighten the isolator mounting bolts.
Noise Considerations
Locate the 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 Bulletins for application information on RTAD chillers.
Important note for Free-cooling units:
To reduce sound levels, a sound enclosure can be mounted around the compressors. For further sound level reduction, the fan speed should be forced onto low speed (e.g. 740 rpm). This can be done using the control panel. Make sure that option 20, shown on the wiring diagram, is correctly wired.
Storage
Extended storage of the outdoor unit prior to installation requires the following 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.
CAUTION! Refer to nameplate for unit weight and additional installation instructions contained inside the control panel. Other lifting arrangements may cause equipment damage or serious personal injury.
