Manufacturer reserves the right to discontinue, or change at any time, specifications or designs without notice and without incurring obligations.Catalog No. 04-53190061-01 Printed in U.S.A. Form 19/23-8SS Pg 1 6-19 Replaces: 19/23-7SSStart-Up and Service InstructionsSAFETY CONSIDERATIONSCentrifugal and screw compressor liquid chillers are designed toprovide safe and reliable service when operated within designspecifications. When operating this equipment, use good judg-ment and safety precautions to avoid damage to equipment andproperty or injury to personnel.Be sure you understand and follow the procedures and safety pre-cautions contained in the chiller instructions as well as those listedin this guide.DANGERFailure to follow these procedures will result in severe personalinjury or death.ONLY QUALIFIED electrical personnel familiar with theconstruction and operation of this equipment and the hazardsinvolved should install, adjust, operate, or service this equip-ment.READ AND UNDERSTAND this manual and other applica-ble manuals in their entirety before proceeding. Failure to ob-serve this precaution could result in severe bodily injury or lossof life.DO NOT install modification kits with power applied to thedrive. Disconnect and lock out incoming power before at-tempting such installation or removal. Failure to observe thisprecaution could result in severe bodily injury or loss of life.UNUSED WIRES in conduit must be grounded at both ends toavoid a possible shock hazard caused by induced voltages. Al-so, if a drive sharing a conduit is being serviced or installed, alldrives using this conduit should be disabled to eliminate thepossible shock hazard from cross-coupled motor leads. Failureto observe these precautions could result in bodily injury.DO NOT VENT refrigerant relief valves within a building.Outlet from rupture disc or relief valve must be vented out-doors in accordance with the latest edition of ANSI/ASHRAE 15 (American National Standards Institute/Ameri-can Society of Heating, Refrigerating, and Air-ConditioningEngineers). The accumulation of refrigerant in an enclosedspace can displace oxygen and cause asphyxiation.PROVIDE adequate ventilation in accordance with ANSI/ASHRAE 15, especially for enclosed and low overhead spac-es. Inhalation of high concentrations of vapor is harmful andmay cause heart irregularities, unconsciousness, or death. Mis-use can be fatal. Vapor is heavier than air and reduces theamount of oxygen available for breathing. Product causes eyeand skin irritation. Decomposition products are hazardous.DO NOT USE OXYGEN to purge lines or to pressurize achiller for any purpose. Oxygen gas reacts violently with oil,grease, and other common substances.(Dangers continued in next column.)DANGERNEVER EXCEED specified test pressures. VERIFY the al-lowable test pressure by checking the instruction literature andthe design pressures on the equipment nameplate.DO NOT USE air for leak testing. Use only refrigerant or drynitrogen.DO NOT VALVE OFF any safety device.BE SURE that all pressure relief devices are properly installedand functioning before operating any chiller.THERE IS A RISK OF INJURY OR DEATH by electrocu-tion. High voltage may be present on the motor leads eventhough the motor is not running. Open the power supply dis-connect before touching motor leads or terminals.WARNINGFailure to follow these procedures may result in personal inju-ry or death.DO NOT USE TORCH to remove any component. Systemcontains oil and refrigerant under pressure.To remove a component, wear protective gloves and gogglesand proceed as follows:a. Shut off electrical power to unit.b. Recover refrigerant to relieve all pressure from systemusing both high-pressure and low-pressure ports.c. Traces of vapor should be displaced with nitrogen andthe work area should be well ventilated. Refrigerant incontact with an open flame produces toxic gases.d. Cut component connection tubing with tubing cutter andremove component from unit. Use a pan to catch any oilthat may come out of the lines and as a gage for howmuch oil to add to the system.e. Carefully unsweat remaining tubing stubs when neces-sary. Oil can ignite when exposed to torch flame.DO NOT work on high-voltage equipment unless you are aqualified electrician.DO NOT WORK ON electrical components, including controlpanels, switches, VFD, or oil heater until you are sure ALLPOWER IS OFF and no residual voltage can leak from capaci-tors or solid-state components.LOCK OPEN AND TAG electrical circuits during servicing.IF WORK IS INTERRUPTED, confirm that all circuits arede-energized before resuming work.AVOID SPILLING liquid refrigerant on skin or getting it intothe eyes. USE SAFETY GOGGLES. Wash any spills fromthe skin with soap and water. If liquid refrigerant enters theeyes, IMMEDIATELY FLUSH EYES with water and con-sult a physician.(Warnings continued on next page.)19XRV, 23XRVwith PIC III/PIC 6 ControlsRockwell PowerFlex 755 VFD Option
