19XR 50/60 Hz Hermetic Centrifugal Liquid Chillers with HFC-134a
Installation Instructions
SAFETY CONSIDERATIONS
Centrifugal liquid chillers are designed to provide safe and reliable service when operated within design speci- ®cations. When operating this equipment, use good judgment and safety precautions to avoid damage to equipment and property or injury to personnel.
Be sure you understand and follow the procedures and safety precautions contained in the machine instructions, as well as those listed in this guide.
DO NOT VENT refrigerant relief devices within a building. Outlet from rupture disc or relief valve must be vented outdoors in accordance with the latest edition of ANSI/ASHRAE 15 (American National Standards Institute/American Society of Heating, Refrigeration and Air-Conditioning Engineers) (Safety Code for Mechanical Refrigeration). The accumulation of refrigerant in an enclosed space can displace oxygen and cause asphyxiation.
PROVIDE adequate ventilation in accordance with ANSI/ ASHRAE 15, especially for enclosed and low overhead spaces. Inhalation of high concentrations of vapor is harmful and may cause heart irregularities, unconsciousness, or death. Intentional misuse can be fatal. Vapor is heavier than air and reduces the amount of oxygen available for breathing. Product causes eye and skin irritation. Decomposition products are hazardous.
DO NOT USE OXYGEN to purge lines or to pressurize a machine for any purpose. Oxygen gas reacts violently with oil, grease, and other common substances.
DO NOT USE air to leak test. Use only refrigerant or dry nitrogen.
NEVER EXCEED speci®ed test pressures. VERIFY the allowable test pressure by checking the instruction literature and the design pressures on the equipment nameplate.
DO NOT VALVE OFF any safety device.
BE SURE that all pressure relief devices are properly installed and functioning before operating any machine.
RISK OF INJURY OR DEATH by electrocution. High voltage is present on motor leads even though the motor is not running when a solid state or inside-delta mechanical starter is used. Open the power supply disconnect before touching motor leads or terminals.
DO NOT WELD OR FLAMECUT any refrigerant line or vessel until all refrigerant (liquid and vapor) has been removed from chiller. Traces of vapor should be displaced with dry air or nitrogen and the work area should be well ventilated. Refrigerant in contact with an open ¯ame produces toxic gases.
DO NOT USE eyebolts or eyebolt holes to rig machine sections or the entire assembly.
DO NOT work on high-voltage equipment unless you are a quali®ed electrician.
DO NOT WORK ON electrical components, including control panels, switches, starters, or oil heater until you are sure ALL POWER IS OFF and no residual voltage can leak from capacitors or solid-state components.
LOCK OPEN AND TAG electrical circuits during servicing. IF WORK IS INTERRUPTED, con®rm that all circuits are deenergized before resuming work.
AVOID SPILLING liquid refrigerant on skin or getting it into the eyes. USE SAFETY GOGGLES. Wash any spills from the skin with soap and water. If liquid refrigerant enters the eyes, IMMEDIATELY FLUSH EYES with water and consult a physician.
NEVER APPLY an open ¯ame or live steam to a refrigerant cylinder. Dangerous over pressure can result. When it is necessary to heat refrigerant, use only warm (110 F [43 C]) water.
DO NOT REUSE disposable (nonreturnable) cylinders or attempt to re®ll them. It is DANGEROUS AND ILLEGAL. When cylinder is emptied, evacuate remaining gas pressure, loosen the collar, and unscrew and discard the valve stem. DO NOT INCINERATE.
CHECK THE REFRIGERANT TYPE before adding refrigerant to the machine. The introduction of the wrong refrigerant can cause machine damage or malfunction.
Operation of this equipment with refrigerants other than those cited herein should comply with ANSI/ASHRAE15 (latest edition). Contact Carrier for further information on use of this machine with other refrigerants.
DO NOT ATTEMPT TO REMOVE ®ttings, covers, etc., while machine is under pressure or while machine is running. Be sure pressure is at 0 psig (0 kPa) before breaking any refrigerant connection.
CAREFULLY INSPECT all relief valves, rupture discs, and other relief devices AT LEAST ONCE A YEAR. If machine operates in a corrosive atmosphere, inspect the devices at more frequent intervals.
DO NOT ATTEMPT TO REPAIR OR RECONDITION any relief valve when corrosion or build-up of foreign material (rust, dirt, scale, etc.) is found within the valve body or mechanism. Replace the valve.
DO NOT install relief devices in series or backwards.
USE CARE when working near or in line with a compressed spring. Sudden release of the spring can cause it and objects in its path to act as projectiles.
DO NOT STEP on refrigerant lines. Broken lines can whip about and release refrigerant, causing personal injury.
DO NOT climb over a machine. Use platform, catwalk, or staging. Follow safe practices when using ladders.
USE MECHANICAL EQUIPMENT (crane, hoist, etc.) to lift or move inspection covers or other heavy components. Even if components are light, use mechanical equipment when there is a risk of slipping or losing your balance.
BE AWARE that certain automatic start arrangements CAN ENGAGE THE STARTER, TOWER FAN, OR PUMPS. Open the disconnect ahead of the starter, tower fan, and pumps. Shut off the machine or pump before servicing equipment.
USE only repaired or replacement parts that meet the code requirements of the original equipment.
DO NOT VENT OR DRAIN waterboxes containing industrial brines, liquid, gases, or semisolids without the permission of your process control group.
DO NOT LOOSEN waterbox cover bolts until the waterbox has been completely drained.
DOUBLE-CHECK that coupling nut wrenches, dial indicators, or other items have been removed before rotating any shafts.
DO NOT LOOSEN a packing gland nut before checking that the nut has a positive thread engagement.
PERIODICALLY INSPECT all valves, ®ttings, and piping for corrosion, rust, leaks, or damage.
PROVIDE A DRAIN connection in the vent line near each pressure relief device to prevent a build-up of condensate or rain water.
Manufacturer reserves the right to discontinue, or change at any time, speci®cations or designs without notice and without incurring obligations.

INSPECT SHIPMENT
Do not open any valves or loosen any connections. The standard 19XR machine is shipped with a full refrigerant charge. Some machines may be shipped with a nitrogen holding charge as an option.
1.Inspect for shipping damage while machine is still on shipping 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 packages until beginning installation. All openings are closed with covers or plugs to prevent dirt and debris from entering machine components during shipping. A full operating 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 protective 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 remove 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 entire 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 adequate for machine weight. See Fig. 3 and 4 for machine weights.
NOTE: These weights are broken down into component sections for use when installing the unit in sections. For the complete machine weight, add all component 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 before lifting if cooler size is 10 through 67.
