Manufacturer reserves the right to discontinue, or change at any time, specifications or designs without notice and without incurring obligations.Catalog No. 04-53190012-01 Printed in U.S.A. Form 19XRV-3SS Pg 1 711 3-11 Replaces: NewStart-Up and Service InstructionsSAFETY CONSIDERATIONSCentrifugal liquid chillers are designed to provide safe andreliable service when operated within design specifica-tions. When operating this equipment, use good judgmentand safety precautions to avoid damage to equipment andproperty or injury to personnel.Be sure you understand and follow the procedures andsafety precautions contained in the chiller instructions aswell as those listed in this guide.ONLY QUALIFIED Electrical Personnel familiar with the constructionand operation of this equipment and the hazards involved should install,adjust, operate, or service this equipment.READ AND UNDERSTAND this manual and other applicable manuals intheir entirety before proceeding. Failure to observe this precaution couldresult in severe bodily injury or loss of life.DO NOT install modification kits with power applied to the drive. Discon-nect and lock out incoming power before attempting such installation orremoval. Failure to observe this precaution could result in severe bodilyinjury or loss of lifeUNUSED WIRES in conduit must be grounded at both ends to avoid apossible shock hazard caused by induced voltages. Also, if a drive sharinga conduit is being serviced or installed; all drives using this conduit shouldbe disabled to eliminate the possible shock hazard from cross-coupledmotor leads. Failure to observe these precautions could result in bodilyinjury.DO NOT VENT refrigerant relief valves within a building. Outlet fromrupture disc or relief valve must be vented outdoors in accordance with thelatest edition of ANSI/ASHRAE 15 (American National Standards Insti-tute/American Society of Heating, Refrigerating, and Air ConditioningEngineers). The accumulation of refrigerant in an enclosed space can dis-place oxygen and cause asphyxiation.PROVIDE adequate ventilation in accordance with ANSI/ASHRAE 15,especially for enclosed and low overhead spaces. Inhalation of high con-centrations of vapor is harmful and may cause heart irregularities, uncon-sciousness, or death. Misuse can be fatal. Vapor is heavier than air andreduces the amount of oxygen available for breathing. Product causes eyeand skin irritation. Decomposition products are hazardous.DO NOT USE OXYGEN to purge lines or to pressurize a chiller for anypurpose. Oxygen gas reacts violently with oil, grease, and other commonsubstances.NEVER EXCEED specified test pressures, VERIFY the allowable testpressure by checking the instruction literature and the design pressures onthe equipment nameplate.DO NOT USE air for leak testing. Use only refrigerant or dry nitrogen.DO NOT VALVE OFF any safety device.BE SURE that all pressure relief devices are properly installed and func-tioning before operating any chiller.THERE IS A RISK OF INJURY OR DEATH by electrocution. High volt-age may be present on the motor leads even though the motor is not run-ning. Open the power supply disconnect before touching motor leads orterminals.DO NOT WELD OR FLAMECUT any refrigerant line or vessel until allrefrigerant (liquid and vapor) has been removed from chiller. Traces ofvapor should be displaced with dry air or nitrogen and the work areashould be well ventilated. Refrigerant in contact with an open flame pro-duces toxic gases.DO NOT work on high-voltage equipment unless you are a qualified elec-trician.DO NOT WORK ON electrical components, including control panels,switches, VFD, or oil heater until you are sure ALL POWER IS OFF andno residual voltage can leak from capacitors or solid-state components.LOCK OPEN AND TAG electrical circuits during servicing. IF WORK ISINTERRUPTED, confirm that all circuits are deenergized before resumingwork.AVOID SPILLING liquid refrigerant on skin or getting it into the eyes.USE SAFETY GOGGLES. Wash any spills from the skin with soap andwater. If liquid refrigerant enters the eyes, IMMEDIATELY FLUSH EYESwith water and consult a physician.DO NOT ATTEMPT TO REMOVE fittings, covers, etc., while chiller isunder pressure or while chiller is running. Be sure pressure is at 0 psig (0kPa) before breaking any refrigerant connection.TO AVOID an electric shock hazard, verify that the voltage on the buscapacitors has discharged completely before servicing. Check the DC busvoltage at the Power Terminal Block by measuring between the +DC and -DC terminals, between the +DC terminal and the chassis, and between the-DC terminal and the chassis. The voltage must be zero for all three mea-surements.THE USER is responsible to conform with all applicable local, national,and international codes. Failure to observe this precaution could result indamage to, or destruction of, the equipment.THIS DRIVE contains ESD (Electrostatic Discharge) sensitive parts andassemblies. Static control precautions are required when installing, testing,servicing or repairing this assembly. Component damage may result ifESD control procedures are not followed. For static control procedures,reference Rockwell publication Guarding Against Electrostatic Damage, orany other applicable ESD protection handbook.DO NOT alter the setting of any jumper. Failure to observe this precautioncould result in damage to, or destruction of, the equipment.USE OF power correction capacitors on the output of the drive can resultin erratic operation of the motor, nuisance tripping, and/or permanent dam-age to the drive. Remove power correction capacitors before proceeding.Failure to observe this precaution could result in damage to, or destructionof, the equipment.MOST CODES require that upstream branch circuit protection be pro-vided to protect input power wiring. If fuses are chosen as the protectionmethod, refer to the PowerFlex 750 user manual. Failure to observe thisprecaution could result in damage to, or destruction of, the equipment.DO NOT route signal and control wiring with power wiring in the sameconduit. This can cause interference with drive operation. Failure toobserve this precaution could result in damage to, or destruction of, theequipment.DISTRIBUTION SYSTEM short circuit capacity shall not exceed the rat-ing of the drive. Failure to observe this precaution could result in damageto, or destruction of, the equipment.DO NOT STEP on refrigerant lines. Broken lines can whip about andrelease refrigerant, causing personal injury.DO NOT climb over a chiller. Use platform, catwalk, or staging. Followsafe practices when using ladders.USE MECHANICAL EQUIPMENT (crane, hoist, etc.) to lift or moveinspection covers or other heavy components. Even if components arelight, use mechanical equipment when there is a risk of slipping or losingyour balance.BE AWARE that certain automatic start arrangements CAN ENGAGETHE VFD, TOWER FAN, OR PUMPS. Open the disconnect ahead of theVFD, tower fans, or pumps.USE only repair or replacement parts that meet the code requirements ofthe original equipment.PERIODICALLY INSPECT all valves, fittings, and piping for corrosion,rust, leaks, or damage.DANGERWARNINGCAUTION19XRVwith PIC III ControlsRockwell PowerFlex 755 VFD Option
