Installation Instructions SAFETY CONSIDERATIONS
Centrifugal liquid chillers are designed to provide safe and reliable service when operated within design specifi- cations. When operating this equipment, use good judg- ment 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 instruc- tions, as well as those listed in this guide.
DANGER
Failure to follow these procedures will result in severe per- sonal injury or death. DO NOT VENT refrigerant relief devices within a build- ing. 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, Refrigerating and Air-Con- ditioning Engineers) (Safety Code for Mechanical Refrig- eration). 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 harm- ful 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 breath- ing. 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 specified test pressures. VERIFY the allowable test pressure by checking the instruction litera- ture 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.
WARNING
Failure to follow these procedures may result in personal injury or death. DO NOT USE TORCH to remove any component. System contains oil and refrigerant under pressure. To remove a component, wear protective gloves and gog- gles and proceed as follows: a. Shut off electrical power to unit. b. Recover refrigerant to relieve all pressure from sys-
tem using both high-pressure and low pressure ports. c. Traces of vapor should be displaced with nitrogen
and the work area should be well ventilated. Refrig- erant in contact with an open flame produces toxic gases.
d. Cut component connection tubing with tubing cutter and remove component from unit. Use a pan to catch any oil that may come out of the lines and as a gage for how much oil to add to the system.
e. Carefully unsweat remaining tubing stubs when nec- essary. Oil can ignite when exposed to torch flame.
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 qualified 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 servic- ing. IF WORK IS INTERRUPTED, confirm that all cir- cuits are de-energized 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 flame or live steam to a refriger- ant 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 refill them. It is DANGEROUS AND ILLE- GAL. 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. (Warnings continued on next page.)

INSTALLATION
Step 1 Receive the Machine INSPECT SHIPMENT
1. Inspect for shipping damage while machine is still on shipping conveyance. If machine appears to be damaged
WARNING
Operation of this equipment with refrigerants other than those cited herein should comply with ANSI/ASHRAE 15 (latest edition). Contact Carrier for further information on use of this machine with other refrigerants. DO NOT ATTEMPT TO REMOVE fittings, covers, etc., while machine is under pressure or while machine is run- ning. 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 com- pressed spring. Sudden release of the spring can cause it and objects in its path to act as projectiles.
CAUTION
Failure to follow these procedures may result in personal injury or damage to equipment. 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 ser- vicing 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 water- box has been completely drained. DOUBLE-CHECK that coupling nut wrenches, dial indi- cators, 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, fittings, 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. DO NOT re-use compressor oil or any oil that has been exposed to the atmosphere. Dispose of oil per local codes and regulations. DO NOT leave refrigerant system open to air any longer than the actual time required to service the equipment. Seal circuits being serviced and charge with dry nitrogen to pre- vent oil contamination when timely repairs cannot be completed.
CAUTION
Do not open any valves or loosen any connections. The 19XR, 19XRV machine may be shipped with a nitrogen holding charge in both modules. Damage to machine may result.

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 The machine model number, seri- al number, and heat exchanger sizes are stamped on machine identification nameplate (Fig. 1-3). Check this information against shipping papers and job data.
INSTALLATION REQUIREMENTS Prior to starting the chillers electrical installation, certain requirements should be checked. Input power wire sizes, branch circuit protection, and control wiring are all areas that need to be evaluated. Determine Wire Size Requirements Wire size should be determined based on the size of the conduit openings, and applicable local, national, and international codes (e.g., NEC [National Electric Code]/CEC [California Energy Commis- sion] regulations). General recommendations are included in the Carrier field wiring drawings. Conduit Entry Size It is important to determine the size of the conduit openings in the enclosure power entry plate so that the wire planned for a specific entry point will fit through the opening. Do NOT punch holes or drill into the top surface of
starter or drive. Knockouts are provided on the side of the enclosure. Recommended Control and Signal Wire Sizes The rec- ommended minimum size wire to connect I/O signals to the control terminal blocks is 18 AWG (American Wire Gage). Recommended terminal tightening torque is 7 to 9 in.-lb (0.79 to 1.02 N-m). Recommended Airflow Clearances Be sure there is ade- quate clearance for air circulation around the enclosure. A 6-in. (152.4 mm) minimum clearance is required wherever vents are located in the starter or drive enclosure. Service Clearances Verify that there are adequate service clearances as identified in Fig. 4. Verify Adequate Power Supply It is important to verify that the building power will meet the input power requirements of the Machine Electrical Data nameplate input power rating. Be sure the input power to the chiller corresponds to the chill- ers nameplate voltage, current, and frequency. PROVIDE MACHINE PROTECTION Store machine and starter indoors, protected from construction dirt and mois- ture. Inspect under shipping tarps, bags, or crates to be sure that water has not collected during transit. Keep protective shipping covers in place until machine is ready for installation.
It is important to properly plan before installing a 19XR, XRV unit to ensure that the environmental and operating con- ditions are satisfactory and the machine is protected. The in- stallation must comply with all requirements in the certified prints. Operating Environment Chiller should be installed in an indoor environment where the ambient temperature is between 40 and 104 F (4 and 40 C) with a relative humidity of 95% or less. To ensure that electrical components operate properly, do not locate the chiller in an area exposed to dust, dirt, corrosive fumes, or excessive heat and humidity.
Step 2 Rig the Machine The 19XR, 19XRV machine can be rigged as an entire assembly. It also has flanged connections that allow the compressor, cooler, and condenser sections to be separated and rigged individually. RIG MACHINE ASSEMBLY See rigging instructions on label attached to machine. Refer to rigging guide (Fig. 5 and 6), dimensions in Fig. 4, and physical data in Tables 1-10. Lift ma- chine only from the points indicated in rigging guide. Each lift- ing cable or chain must be capable of supporting the entire weight of the machine.
Contractors are not authorized to disassemble any part of the chiller without Carrier's supervision. Any request otherwise must be in writing from the Carrier Service Manager. NOTE: Carrier suggests that a structural engineer be consulted if transmission of vibrations from mechanical equipment is of concern.
