Proceduresin this manual are arranged in the sequence required for properchiller start-up and operation.ABBREVIATIONS AND EXPLANATIONSFrequently used abbreviations in this manual include:Words printed in all capital letters or in italics may beviewed on the International Chiller Visual Controller (ICVC)(e.g., LOCAL, CCN, ALARM, etc.).Words printed in both all capital letters and italics can alsobe viewed on the ICVC and are parameters (e.g., CONTROLMODE, COMPRESSOR START RELAY, ICE BUILDOPTION, etc.) with associated values (e.g., modes, tempera-tures, percentages, pressures, on, off, etc.).Words printed in all capital letters and in a box representsoftkeys on the ICVC control panel (e.g., , ,, , etc.).This unit uses a microprocessor control system. Do notshort or jumper between terminations on circuit boards ormodules; control or board failure may result.Be aware of electrostatic discharge (static electricity) whenhandling or making contact with circuit boards or moduleconnections. Always touch a chassis (grounded) part todissipate body electrostatic charge before working insidethe VFD enclosure.Use extreme care when handling tools near boards andwhen connecting or disconnecting terminal plugs. Circuitboards can easily be damaged. Always hold boards by theedges and avoid touching components and connections.This equipment uses, and can radiate, radio frequencyenergy. If not installed and used in accordance with theinstruction manual, it may cause interference to radiocommunications. It has been tested and found to complywith the limits for a Class A computing device pursuant toSubpart J of Part 15 of FCC Rules, which are designed toprovide reasonable protection against such interferencewhen operated in a commercial environment. Operation ofthis equipment in a residential area is likely to causeinterference, in which case the user, at his own expense,will be required to take whatever measures may berequired to correct the interference.Always store and transport replacement or defective boardsin anti-static shipping bag.CCM — Chiller Control ModuleCCN — Carrier Comfort Network®CCW — CounterclockwiseCW — ClockwiseECDW — Entering Condenser WaterECW — Entering Chilled WaterEMS — Energy Management SystemHGBP — Hot Gas BypassI/O — Input/OutputICVC — International Chiller Visual ControllerLCD — Liquid Crystal DisplayLCDW — Leaving Condenser WaterLCW — Leaving Chilled WaterLED — Light-Emitting DiodeOLTA — Overload Trip AmpsPIC III — Product Integrated Controls IIIRLA — Rated Load AmpsSI — International System of UnitsTXV — Thermostatic Expansion ValveVFD — Variable Frequency DriveENTER EXITINCREASE QUIT
