RIGGING UNIT (See Fig. 16-18) — The 30XA080-500 units are designed for overhead rigging and it is important that this method be used. Holes are provided in frame base channels, marked for rigging (see rigging label on unit). Field-supplied shackles are required to facilitate lifting. Secure the shackles to the base rails at the points noted on the rigging label. See Table 2 for the number of lifting points for each unit.

Do not use a forklift truck to move the units.

Use spreader bars to keep cables or chains clear of unit sides. As further protection plywood sheets may be placed against sides of unit, behind cables or chains. Run cables or chains to a central suspension point so that angle from horizontal is not less than 45 degrees. Raise and set unit down carefully.

See Fig. 16-18 for rigging centers of gravity.

For shipping, some domestic units and all export units are mounted on a wooden skid under entire base of unit. Skid can be removed before unit is moved to installation site. Lift the unit from above to remove skid. See Fig. 16-18 for rigging center of gravity. On export units, the top skid can be used as the spreader bars. If the unit was shipped with a shipping bag, the bag must be removed to gain access to the rigging holes in the base rail.

If overhead rigging is not available, the unit can be moved on rollers or dragged. When unit is moved on rollers, the unit

skid, if equipped, must be removed. To lift the unit, use jacks at the rigging points. Use a minimum number of rollers to distrib- ute the load such that the rollers are no more than 6 ft (1.8 m) apart. If the unit is to be dragged, lift the unit as described above, and place unit on a pad. Apply moving force to the pad, and not the unit. When in its final location, raise the unit and remove the pad. If the unit was shipped with coil protection, it must be removed before start-up. The shipping bag for export units must be removed before start-up.

Step 3 — Cooler Fluid and Drain Piping Con- nections — See Fig. 19-22 for piping applications.

CAUTION

Remove the chilled water flow switch, entering and leaving water thermistors before welding connecting piping. Rein- stall flow switch and thermistors after welding is complete. Failure to remove these devices may cause unit damage.

GENERAL — The factory-installed victaulic connections al- low clamp-on connection of water lines to the coolers in all 30XA units. A flow sensor is factory-installed in the side of the entering fluid nozzle. See Fig. 23. See Table 3 for 30XA unit operating range. See Fig. 20 for cooler option dimensions.

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.
