CAUTION - NOTICE TO RIGGERS:

ALL PANELS MUST BE IN PLACE WHEN RIGGING. DO NOT ATTEMPT TO FORK THESE UNITS IF NO SKID IS SUPPLIED.

NOTES:

1.1.50 dia. (38.1mm) lifting holes provided for field supplied clevis.

2.Rig with a minimum of 25 ft (7620mm) length chains or cables.

3. If central lifting point is used, it must be a minimum of 13 ft. (3962mm) above the top of the unit.

4.Spreader bars made from steel or double nailed, and notched 2x6's approximately 8 ft. (2438mm) long, must be placed just above the top of the unit (and stacks) to reduce the risk of damage to the top of the unit and coils.

5.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 of one roller every 6 ft. (1829mm) to distribute the load. 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, not the unit. When in its final location, raise the unit and remove the pad.

6.Check bill of lading for shipping weight of unit.

Minimum Loop Volume — The preferred minimum loop vol- ume is dependent on the type of application. In order to obtain leaving water temperature stability for comfort cooling appli- cations, a minimum of 3 gallons per ton (3.25 liters per kW) is required on all unit sizes. For process cooling applications, ap- plications where high stability is critical, or operation at ambient temperatures below 32 F (0° C) is expected, the loop volume should be increased to 6 to 10 gallons per ton (6.46 to

10.76liters per kW) of cooling. In order to achieve this volume, it may be necessary to add a water storage tank to the water loop. If a storage tank is added to the system, it should be properly vented so that the tank can be completely filled and all air eliminated. Failure to do so could cause lack of pump stabil- ity and poor system operation. Any storage tank that is placed in the water loop should have internal baffles to allow thorough mixing of the fluid. See Fig. 24.

System Piping — Proper system design and installation proce- dures should be followed closely. The system must be constructed with pressure tight components and thoroughly tested for installation leaks. Factory-supplied hydronic systems are available with single or dual (for back-up) pumps. The factory-installed system includes all of the components above the line in Fig. 25 and 26.

Installation of water systems should follow sound engineer- ing practice as well as applicable local and industry standards. Improperly designed or installed systems may cause unsatis- factory operation and/or system failure. Consult a water treatment specialist or appropriate literature for information regarding filtration, water treatment, and control devices. Fig- ures 25 and 26 show a typical installation with components that might be installed with the hydronic package of the 30XA unit.

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.
