Step 2 — Place, Mount, and Rig the Unit —

When considering a location for the unit, be sure to consult NEC (National Electrical Code, U.S.A.) and/or local code requirements. Allow sufficient space for airflow, wiring, pip- ing, and service. See Fig. 2-14.

NOTE: To facilitate refrigerant vent piping, all units have fus- ible plugs with 1/4 in. SAE (Society of Automotive Engineers) flares and pressure reliefs with 3/4 in. NPT fittings (if required by local codes).

PLACING UNIT — Locate the unit so that the condenser airflow is unrestricted both above and on the sides of the unit. Airflow and service clearances are 6 ft (1.8 m) around the unit. Acceptable clearance on the sides or ends without control boxes can be reduced to 3 ft (1 m) without sacrificing performance as long as the remaining three sides are unrestricted. Acceptable clearance on the side with a control box can be reduced to 4 ft (1.3 m) due to NEC regulations, without sacrificing performance as long as the remaining three sides are unrestricted. Provide am- ple room for servicing and removing the cooler. See Fig. 2-14 for required clearances. Local codes for clearances take precedence

over the manufacturer’s recommendations when local codes call for greater clearances.

If multiple units are installed at the same site, a separation of

10 ft (3 m) between the sides of the machines is required to maintain proper airflow and minimize the chances of condens- er air recirculation.

MOUNTING UNIT — The unit may be mounted on a level pad directly on the base rails, on a raised mounting rail around the unit, or on vibration isolation springs. For all units, ensure placement area is strong enough to support unit operating weight. See Tables 1A and 1B. Mounting holes are provided for securing the unit to the pad, mounting rail or vibration isolation springs. Bolt the unit securely to pad or rails. If vibra- tion isolators (field-supplied) are required for a particular installation, refer to unit weight distribution in Fig. 15A-15C to aid in the proper selection of isolators. The 30XA units can be mounted directly on spring isolators. Once installed, the unit must be level to within 1/8-in. per ft (1 cm per meter) along the long axis of the oil separator. This is required for oil return to the compressor(s).

30XA080-500 specifications

The Carrier 30XA080-500 is a sophisticated air-cooled chiller designed for large commercial and industrial applications, renowned for its energy efficiency and reliability. This model is part of Carrier's extensive range of chillers, providing an optimal solution for space cooling needs while supporting sustainability goals.

One of the main features of the 30XA080-500 is its advanced scroll compressor technology. This design not only enhances the chiller's efficiency but also ensures quieter operation. The compressors operate with a high efficiency at partial loads, making the 30XA080-500 ideal for buildings with varying cooling demands. The unit also incorporates multiple compressors, allowing for enhanced reliability through redundancy; if one compressor fails, others can maintain performance.

The 30XA080-500 is equipped with high-performance evaporators and condensers which facilitate superior heat exchange. The unit features a fin-and-tube heat exchanger design, optimized for maximum surface area and minimal air resistance, thus enhancing overall performance. Moreover, the chiller is built with microchannel technology, which significantly reduces the refrigerant charge while improving efficiency through better heat transfer.

In terms of controls, the Carrier 30XA080-500 utilizes advanced VFD (Variable Frequency Drive) technology. This allows the system to adjust motor speed to match building loads, further increasing efficiency and reducing energy consumption. The intuitive control options enable users to monitor performance and make adjustments easily, helping optimize system operations in real time.

Another highlight of the 30XA080-500 is its environmentally conscious refrigerant, R-410A, which is known for its low Global Warming Potential (GWP). This makes the unit compliant with current and future environmental regulations, ensuring that users can operate within legal limits while reducing their carbon footprint.

The durability of the 30XA080-500 is enhanced by a rugged construction designed to withstand various weather conditions, making it suitable for outdoor installation. Insulated panels and protective coatings guard against corrosion, extending the lifespan of components and reducing maintenance costs.

In conclusion, the Carrier 30XA080-500 is a high-efficiency chiller that offers advanced technology, reliable performance, and environmental consciousness, making it an excellent choice for modern commercial buildings seeking to balance cooling needs with sustainability and energy savings. Its combination of innovative features positions it as a leader in the chiller market.
