OperationControl and unit operationThe control is through theTRACER CH530 control module.• Check the chilled water pump(s)operates• Start up the unit followingprocedure described in manualCG-SVU02A. The unit willoperate correctly when there issufficient water flow. Thecompressors will start up if theevaporator water leavingtemperature is above the controlmodule setpoint.Weekly start up• Check the chilled water pump(s)operates• Start up the unit followingprocedure described in manualCG-SVU02A.Weekend shutdown• If the unit needs to be shut downfor a short period of time, stopthe unit following proceduredescribed in manual CG-SVU02A(See "Clock" menu)• If the unit is shut down for alonger period, see under"Seasonal shutdown", below.• Ensure that all safeties are takento prevent frost damages duringnegative ambient temperature.• Do not put the generaldisconnect switches to off,except if the unit is drained.Trane does not recommenddraining the unit, due to the factthat it increases tube corrosion.Seasonal shutdown• Check water flows and interlocks.• Check glycol % in the chilledwater circuit if glycol presence isrequired• Carry out leak test.• Carry out oil analysis• Record operating pressures,temperatures, amperages andvoltage.• Check operation ofmachines/compare conditions ofoperation against originalcommissioning data.• Stop the unit followingprocedure described in manualCG-SVU02A.• Ensure that all safeties are takento prevent frost damages duringnegative ambient temperature.• Fill out the visit log sheet andreview with the operator• Do not put the generaldisconnect switch to off, except ifthe unit is drained.Trane does not recommenddraining the unit, due to the factthat it increases tube corrosion.Seasonal start-up• Check water flows and interlocks.• Check Ethylene glycol % in thechilled water circuit if glycolpresence is required• Check operational set points andperformance.• Calibrate controls.• Check operation of all safetydevices.• Inspect contacts and tightenterminals.• Megger the motor compressorwindings.• Record operating pressures,temperatures, amperages andvoltage.• Carry out leak test.• Check configuration of unitcontrol module.• Change the oil as required basedupon results of the oil analysismade during seasonal shutdown.Get the 8 condition measurementsat the same time, on each circuit.• HP• LP• Suction temperature• Discharge temperature• Liquid temperature• Water entering temperature• Water leaving temperature• Outdoor ambient temperatureThen calculate the sub-cooling andsuperheat. No diagnosis can beaccurate with one of these recordsmissing.• Check operation ofmachines/compare conditions ofoperation against originalcommissioning data.• Fill out the visit log sheet andreview with the operator46CG-SVX06A-E4
MaintenanceMaintenance InstructionsThe following maintenanceinstructions are part of maintenanceoperations required for thisequipment. A qualified technician isneeded for regular maintenance aspart of a regular maintenancecontract.Carry out all operations as requiredby schedule. This will ensure longunit service life and reduce thepossibility of serious and costlybreakdown. Keep service records upto date, showing monthlyinformation on unit operations.These records can be of great helpto maintenance personneldiagnostics. Similarly, if machineoperator keeps a log of changes inunit operating conditions, problemscan be identified and solutionsfound before more seriousproblems arise.Inspection visit after the first500 hours of operation from unitstart up• Carry out oil analysis• Carry out leak test• Inspect contacts and tightenterminals• Record operating pressures,temperatures, amperages andvoltage• Check operation ofmachines/compare conditions ofoperation against originalcommissioning data• Fill out inspection visit log sheetand review with the operator• Check and clean the strainerMonthly preventive visit• Carry out leak test• Oil test of acidity• Check Ethylene glycol % in thechilled water circuit if glycolpresence is required• Inspect contacts and tightenterminals• Record operating pressures,temperatures, amperages andvoltage• Check operation ofmachines/compare conditions ofoperation against originalcommissioning data• Fill out visit log sheet and reviewwith the operator• Check and clean the strainerCG-SVX06A-E447
