DEHYDRATION

REFRIGERANT CHARGE

Installing, starting up, and servicing this equipment can be hazardous due to system pressures, electrical components, and equipment location. Only trained, qualified installers and service mechanics should install, start up, and service this equipment.

When working on the equipment, observe precautions in the literature, and on tags, stickers, and labels attached to the equipment.

Follow all safety codes.

Wear safety glasses and work gloves.

Use care in handling, rigging, and setting bulky equipment.

WARNING

Electrical shock can cause personal injury and death. Shut off all power to this equipment during installation. There may be more than one disconnect switch. Tag all discon- nect locations to alert others not to restore power until work is completed.

IMPORTANT: This equipment generates, uses, and can radiate radio frequency energy and if not installed and used in accordance with these instructions may cause radio interference. It has been tested and found to comply with the limits of a Class A computing device as defined by FCC (Federal Communications Commission, U.S.A.) regulations, Subpart J of Part 15, which are designed to provide reasonable protection against such interference when operated in a commer- cial environment.

INTRODUCTION

These instructions cover installation of 30XA080-500 air- cooled liquid chillers with electronic controls and units with factory-installed options (FIOPs). See Fig. 1.

INSTALLATION

Storage — If the unit is to be stored for a period of time be- fore installation or start-up, be sure to protect the machine from construction dirt. Keep protective shipping covers in place until the machine is ready for installation.

Step 1 — Inspect Shipment — Inspect unit for dam- age upon arrival. If damage is found, immediately file a claim with the shipping company, and contact your local Carrier representative.

Manufacturer reserves the right to discontinue, or change at any time, specifications or designs without notice and without incurring obligations.

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.
