    OACS Central Chillers : with MG Series Control Instrument INTRODUCTION This manual covers OACS central chillers from 5 to 210 tons (17.2 to 717.4 kW) of cooling capacity using the Advantage MG microprocessor control instrument and fixed displacement scroll compressors and digital scroll compressors. The standard fluid operating temperature range for this chiller is 20°F to 80°F for units using R410A refrigerant. Units using other refrigerants have different standard operating ranges. Units operating below 48°F fluid require the use of a water/propylene glycol to prevent freezing.
