INTRODUCTION

General Ð The 19XR machine is factory assembled, wired, and leak tested. Installation (not by Carrier) consists primarily of establishing water and electrical services to the machine. The rigging, installation, ®eld wiring, ®eld pip- ing, and insulation of waterbox covers are the responsibility of the contractor and/or customer. Carrier has no installation responsibilities for the equipment.

Job Data

Necessary information consists of:

·job contract or speci®cations

·machine location prints

·rigging information

·piping prints and details

·®eld wiring drawings

·starter manufacturer's installation details

·Carrier certi®ed print

INSTALLATION

Receiving the Machine

INSPECT SHIPMENT

Do not open any valves or loosen any connections. The standard 19XR machine is shipped with a full refrig- erant charge. Some machines may be shipped with a ni- trogen holding charge as an option.

1.Inspect for shipping damage while machine is still on ship- ping conveyance. If machine appears to be damaged or has been torn loose from its anchorage, have it examined by transportation inspectors before removal. Forward claim papers directly to transportation company. Manufacturer is not responsible for any damage incurred in transit.

2.Check all items against shipping list. Immediately notify the nearest Carrier representative if any item is missing.

3.To prevent loss or damage, leave all parts in original pack- ages until beginning installation. All openings are closed with covers or plugs to prevent dirt and debris from en- tering machine components during shipping. A full op- erating oil charge is placed in the oil sump before shipment.

IDENTIFY MACHINE Ð The machine model number, serial number, and heat exchanger sizes are stamped on machine identi®cation nameplate (Fig. 1 and 2). Check this information against shipping papers and job data.

PROVIDE MACHINE PROTECTION Ð Protect machine and starter from construction dirt and moisture. Keep pro- tective shipping covers in place until machine is ready for installation.

If machine is exposed to freezing temperatures after water circuits have been installed, open waterbox drains and re- move all water from cooler and condenser. Leave drains open until system is ®lled.

Rigging the Machine Ð The 19XR machine can be rigged as an entire assembly. It also has ¯anged connections that allow the compressor, cooler, and condenser sections to be separated and rigged individually.

RIG MACHINE ASSEMBLY Ð See rigging instructions on label attached to machine. Also refer to rigging guide (Fig. 3 and 4), physical data in Fig. 5, and Tables 1-8B. Lift machine only from the points indicated in rigging guide. Each lifting cable or chain must be capable of supporting the en- tire weight of the machine.

Lifting machine from points other than those speci®ed may result in serious damage to the unit and personal injury. Rigging equipment and procedures must be ad- equate for machine weight. See Fig. 3 and 4 for ma- chine weights.

NOTE: These weights are broken down into compo- nent sections for use when installing the unit in sections. For the complete machine weight, add all com- ponent sections and refrigerant charge together. See Tables 4-8B for machine component weights.

IMPORTANT: Ensure that rigging cable is over the guide bolt or cable hook on the motor end cover be- fore lifting if cooler size is 10 through 67.

19XR specifications

The Carrier 19XR and 19XRV chillers are sophisticated cooling solutions that represent the forefront of HVAC technology. Designed for large commercial and industrial applications, these chillers provide exceptional performance, energy efficiency, and reliability, making them ideal for a variety of environments ranging from hospitals to manufacturing facilities.

One of the most significant features of the Carrier 19XR and 19XRV chillers is their advanced scroll compressor technology. These units employ a tandem scroll design that enhances efficiency while minimizing operational noise. This makes them ideal for urban environments where noise restrictions may be in place. Moreover, the compressors are equipped with variable speed drive options in the 19XRV model, which allows for greater energy savings by adjusting cooling output based on real-time demand.

In addition to their advanced compressors, the 19XR and 19XRV units incorporate the Carrier GreenChoice refrigerant, which has a lower global warming potential compared to traditional refrigerants. This innovative choice not only meets regulatory requirements but also contributes to sustainability goals, making these chillers a responsible choice for environmentally conscious organizations.

The units are engineered with a robust heat exchanger design, which enhances heat transfer efficiency and overall system performance. This ensures optimal operation even in extreme conditions. They feature a microprocessor-based control system that allows for precise monitoring and control of the chiller’s performance, enabling operators to make real-time adjustments to maximize energy efficiency.

The Carrier 19XR and 19XRV chillers also prioritize serviceability. The design incorporates easy access to key components, simplifying maintenance procedures and reducing downtime. This focus on maintainability extends the lifespan of the equipment, leading to lower lifecycle costs.

In terms of connectivity, these chillers are equipped with advanced Building Management System (BMS) integration capabilities. This allows for seamless monitoring and control of the chillers using a centralized platform, facilitating energy management and operational optimization.

Overall, the Carrier 19XR and 19XRV chillers stand out in the market for their blend of cutting-edge technology, energy efficiency, and user-friendly features. They are engineered to meet the demanding needs of modern commercial and industrial applications, making them a preferred choice for facility managers seeking reliable cooling solutions.
