SAFETY CONSIDERATIONSWARNINGInstallation and servicing of air-conditioning equipment can behazardous due to system pressure and electrical components. Onlytrained and qualified service personnel should install, repair, orservice air-conditioning equipment.Untrained personnel can perform basic maintenance functions ofcleaning coils and filters and replacing filters. All other operationsshould be performed by trained service personnel. When workingon air-conditioning equipment, observe precautions in theliterature, tags and labels attached to the unit, and other safetyprecautions that may apply.Follow all safety codes, including ANSI (American NationalStandards Institute) Z223.1. Wear safety glasses and work gloves.Use quenching cloth for unbrazing operations. Have fireextinguisher available for all brazing operations.It is important to recognize safety information. This is the safetyalert symbol. When you see this symbol on the unit and ininstructions or manuals, be alert to the potential for personalinjury.Understand the signal words DANGER, WARNING,CAUTION, and NOTE. These words are used with the safetyalert symbol. DANGER identifies the most serious hazards whichwill result in severe personal injury or death. WARNING signifieshazards which could result in personal injury or death. CAUTIONis used to identify unsafe practices, which may result in minorpersonal injury or product and property damage. NOTE is used tohighlight suggestions which will result in enhanced installation,reliability, or operation.Electrical shock can cause personal injury and death. Shut offall power to this equipment during installation. There may bemore than one disconnect switch. Tag all disconnect locationsto alert others not to restore power until work is completed.DANGERDO NOT USE TORCH to remove any component. Systemcontains oil and refrigerant under pressure.To remove a component, wear protective gloves and goggles and 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 un-sweat remaining tubing stubs when necessary. Oil can ignite when exposed to torch flame.Failure to follow these procedures may result in personalinjury or death.DANGERCAUTIONFailure to follow these procedures will result in severepersonal injury or death.DO NOT VENT refrigerant relief devices 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 AirConditioning Engineers) (Safety Code for MechanicalRefrigeration). The accumulation of refrigerant in anenclosed 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.Intentional misuse can be fatal. Vapor is heavier than air andreduces the amount of oxygen available for breathing. Productcauses eye and skin irritation. Decomposition products arehazardous.DO NOT USE OXYGEN to purge lines or to pressurize amachine 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 drynitrogen.NEVER EXCEED specified test pressures. VERIFY theallowable test pressure by checking the instruction literatureand the design pressures on the equipment nameplate.DO NOT VALVE OFF any safety device.BE SURE that all pressure relief devices are properly installedand functioning before operating any machine.RISK OF INJURY OR DEATH by electrocution. Highvoltage is present on motor leads even though the motor is notrunning when a solid state or inside-delta mechanical starter isused. Open the power supply disconnect before touchingmotor leads or terminals.UNIT DAMAGE HAZARDThis unit uses a microprocessor-based electronic controlsystem. Do not use jumpers or other tools to short out components or to bypass or otherwise depart from recommended procedures. Any short-to-ground of the control board oraccompanying wiring may destroy the electronic modulesor electrical components.CAUTIONTo prevent potential damage to heat exchanger tubes, always run fluid through heat exchanger when adding or removing refrigerant charge. Use appropriate antifreeze solutions in cooler fluid loop to prevent the freezing of heat exchanger or interconnecting piping when the equipment isexposed to temperatures below 32 F (0 C). Proof of flowswitch is factory installed on all models. Do NOT removepower from this chiller during winter shut down periodswithout taking precaution to remove all water from heat exchanger. Failure to properly protect the system from freezing may constitute abuse and may void warranty.CAUTIONCompressors require specific rotation. Test condenserfan(s) first to ensure proper phasing. Swap any two incoming power leads to correct condenser fan rotation beforestarting compressors. Operating the unit without testing thecondenser fan(s) for proper phasing could result in equipment damage.2

See Fig. 1.CAUTIONLCD TOUCH SCREENDO NOT re-use compressor oil or any oil that has been exposed to the atmosphere. Dispose of oil per local codes andregulations. DO NOT leave refrigerant system open to airany longer than the actual time required to service theequipment. Seal circuits being serviced and charge with drynitrogen to prevent oil contamination when timely repairscannot be completed. Failure to follow these proceduresmay result in damage to equipment.ALARMINDICATORLIGHTGENERALThis publication contains Controls, Operation, Start-Up, Service and Troubleshooting information for the 30XA080-501air-cooled liquid chillers with electronic controls.
