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 thisequipment.READ AND UNDERSTAND this manual and otherapplicable manuals in their entirety before proceeding. Failureto observe this precaution could result in severe bodily injuryor loss of life.DO NOT install modification kits with power applied to thedrive. Disconnect and lock out incoming power beforeattempting 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.Also, if a drive sharing a conduit is being serviced or installed,all drives 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 ventedoutdoors in accordance with the latest edition of ANSI/ASHRAE 15 (American National Standards Institute/American Society of Heating, Refrigerating, and Air-Conditioning Engineers). The accumulation of refrigerant inan enclosed space can displace oxygen and cause asphyxiation.PROVIDE adequate ventilation in accordance with ANSI/ASHRAE 15, especially for enclosed and low overheadspaces. Inhalation of high concentrations of vapor is harmfuland may cause heart irregularities, unconsciousness, or death.Misuse 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.)19XR, 19MVwith PIC6 ControlsRockwell PowerFlex 755TL VFD Option
