·Follow all safety codes.

·Wear safety glasses and work gloves.

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

INTRODUCTION

These instructions cover installation of 30HX liquid chill- ers with electronic controls and units with factory-installed options (FIOPSs).

IMPORTANT: This equipment generates, uses, and can radiate radio frequency energy. If not installed and used in accordance with these instructions, this equip- ment may cause radio interference. The equipment has been tested and found to comply with the limits of a Class A computing device as de®ned by the FCC (Federal Communications Commission, U.S.A.) Regu- lations, Subpart J of Part 15, which are designed to provide reasonable protection against such interfer- ence when operated in a commercial environment.

INSTALLATION

Step 1 Ð Inspect Shipment Ð Inspect unit for dam- age upon arrival. If damage is found, ®le a claim with the shipping company right away. Do not store units in an area exposed to weather because of sensitive control mecha- nisms and electronic devices.

Locate unit indoors. When considering unit location, con- sult National Electrical Code (NEC, U.S.A.) and local code requirements. Allow sufficient space for wiring, piping, and service. Install unit in an area which will not be exposed to subfreezing weather. See Fig. 1-4 for clearance details.

Allow the following clearances for service access:

Top

. . . . . . . . . . . . . . . 2 ft (610 mm)

Ends

tube removal at one (either) end;

 

3 ft (914 mm) at opposite end.

Be sure surface beneath the unit is level and is capable of supporting the operating weight of the unit. See Fig. 5 and Tables 1A and 1B for unit operating weights. If necessary, add supporting structure (steel beams or reinforced concrete slabs) to ¯oor to transfer weight to nearest beams.

Step 2 Ð Rig and Place Unit

Rig unit from the top heat exchanger only. Rigging from the bottom heat exchanger will cause the unit to be lifted unsafely. Personal injury or damage to the unit may occur.

Do not remove unit from skid until unit is in its ®nal location. Rig from the rigging holes provided in the top heat exchanger. See Fig. 1-5 for rigging and center of grav- ity information. Lower the unit carefully onto the ¯oor or roller. Push or pull only on the skid, not the unit. If the unit is moved on rollers, use a minimum of 3 evenly-spaced rollers.

30HXA, HXC076-186 specifications

The Carrier 30HXA and 30HXC series is a notable line of chillers designed for commercial applications, providing advanced cooling solutions for various buildings and infrastructures. These models are known for their reliability and efficiency, making them a preferred choice for building managers and facilities engineers.

One of the key features of the Carrier 30HXA and 30HXC series is their use of high-efficiency, variable-speed scroll compressors. This technology allows the chillers to adjust their cooling output based on the actual demand, resulting in significant energy savings, especially during periods of partial load. This responsiveness not only leads to lower operational costs but also reduces wear and tear on the equipment, extending its lifespan.

Another critical aspect of these chillers is their eco-friendly refrigerant options. The 30HXA and 30HXC models utilize R-410A refrigerant, which has a lower environmental impact compared to traditional refrigerants. This commitment to sustainability aligns with modern regulations and climate goals, making these chillers an environmentally responsible choice.

Both series offer a wide range of cooling capacities, from 76,000 to 186,000 BTU/h, catering to various commercial needs. The compact design and modular configurations of these chillers allow for easy installation and integration into existing systems, facilitating retrofits and upgrades without significant disruption.

The 30HXA and 30HXC chillers also feature advanced controls that enhance their operational efficiency. The integrated controls allow for easy monitoring and adjustments, enabling users to optimize performance and minimize energy consumption. Additionally, they can easily interface with building management systems (BMS), providing real-time data and improved operational insights.

Durability is another hallmark of the Carrier 30HXA and 30HXC series. Built with corrosion-resistant materials and designed to withstand harsh weather conditions, these chillers ensure reliable performance in various environments. The robust construction further enhances their longevity, providing consistent cooling solutions for years.

In summary, the Carrier 30HXA and 30HXC series chillers offer advanced technology, eco-friendly refrigerants, energy efficiency through variable-speed compressors, and durable construction. These features come together to provide a reliable and effective cooling solution for a wide range of commercial applications, ensuring comfort and performance while supporting sustainability goals.
