1. Poor Temperature Stability Service Assistance Parts List The System III is designed to maximize heat removal with minimal facility cooling water requirements Under conditions of excessive cooling capacity instability may result The condition may be aggravated by High temperature setpoint Low facility water temperature Small heat load High facility water pressure The situation can be remedied by limiting the available facility cooling water Facility water pressure can be reduced with a pressure regulator before the System 11 However excessive restriction of facility water will reduce the System Ill s capacity If after following these troubleshooting steps your exchanger fails to operate properly contact our Service Department for assistance see Preface After sale Support Before calling please obtain the following information BOM number Serial number Voltage of exchanger Voltage of power source Temperature at which the problem occurs Temperature pressure and flow rate of cooling water supply Software Version Our Service Department can provide you with a complete list of spare parts for your exchanger see Preface After sale Support Before calling please obtain the following information BOM number Serial number 32 SALA 491194 Ajquassy que J9J9 N MO Y40949 Jexoe1g jJeijeM J010IN JeDueuox3 Sleld Josues eunjejeduje abned eunsseJg SALA jeg em e Y2.
