17/19EX 50/60 Hz 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 ASHRAE (American Society of Heating, Refrigeration and Air Conditioning Engineers) 15. The accumulation of refrigerant in an enclosed space can displace oxygen and cause asphyxiation.
PROVIDE adequate ventilation in accordance with 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.
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 ASHRAE-15 (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 17/19EX machine may be shipped with a nitrogen holding charge or with the refrigerant charge isolated within the utility vessel.
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 the machine's components during shipping. A full operating oil charge is placed in the oil sump of the compressor before shipment.
IDENTIFY MACHINE Ð The machine model number, serial number, and heat exchanger sizes are stamped on machine identi®cation nameplate (Fig. 1). 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 17/19EX machine can be rigged as an entire assembly. It also has ¯anged connections that allow the compressor, utility vessel, cooler, and condenser sections to be separated for ease of installation. Figures 2 and 3 show 17/19EX components.
RIG MACHINE ASSEMBLY Ð See rigging instructions on label attached to machine. Also refer to the rigging information found in Fig. 4-9 and Tables 1-12. Lift machine only from the 4 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 Table 1 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. Total machine weight is also stenciled on the cooler and condenser sections.

To Separate Cooler From Utility Vessel
1.Remove condenser (see previous section).
2.Cut copper lines (Fig. 6, Items 6 and 8).
3.Unbolt liquid refrigerant line at ¯ange (Fig. 7, Item 3).
4.Connect rigging to all four corners of the cooler before lifting the unit.
5.Unbolt connections to the utility vessel (Fig. 6, Items 5 and 10).
To Assemble the Machine
1.Follow disassembly instructions (in reverse order) and bolt all ¯anges back together using a gasket sealant. The following torque requirements are speci®ed:
2.All gasketed or O-ring joints which have been disassembled must be assembled using new gaskets and O-rings. These new gaskets and O-rings (along with gasket sealant, O-ring lubricant, and copper line couplings) are available through your Carrier representative.
3.Braze all copper lines back together using a suitable brazing material for copper. Carrier recommends an AWS (American Welding Society) Classi®cation BCuP-2.
Do not tilt the compressor; oil is contained in the oil sump.

Additional Notes
1.Use silicon grease on new O-rings when re®tting.
2.Use gasket sealant on new gaskets when re®tting.
3.Cooler, utility, and condenser vessels may be rigged vertically, as separate components. Rigging should be ®xed to all four corners of the tube sheet.
4.New gaskets, grease for O-rings, and gasket sealant for a complete take-apart operation are available in a kit. Contact your Carrier representative.
*This torque is used to rig the entire machine. Once the machine is in place, if no further rigging is anticipated, the bolt torque can be reduced to 280 ft-lb (380 N-m).

*If a machine con®guration other than 2-pass, 150 psig (1034 kPa), NIH waterbox con®guration is used, refer to Tables 3 and 4 to obtain the additional dry and water weights that must be added to the values shown in this table.
²Cooler and condenser weights shown are based upon 2-pass, nozzle-in-head (NIH) waterboxes with 150 psig (1034 kPa) covers. Includes components attached to cooler, but does not include suction/discharge, elbow, or other interconnecting piping.
**Dry weight includes all components attached to economizer: Covers, ¯oat valves, brackets, control center (31 lb [14 kg]), and power panel (20 lb [9 kg]). Dry weight does not include compressor weight, motor weight, or pumpout condensing unit weight. The pumpout condensing unit weight is 210 lb (95 kg). For compressor and motor weights, refer to Tables 6, 7, 8, 10A, and 10B.
²²Operating weight includes the sum of the dry weight, refrigerant weight, and water weight.
