Installation Operation Maintenance

General Start-upStart-upFollow the instructions below tocorrectly start-up the unit.Installation and chiller inspection• Ensure that all the operationsabove (start-up preparation), arefollowed.• Follow the instruction stuckinside the electrical cabinet:• Put the plexiglass supplied byTrane in front of the powerterminal.• Ensure all water and refrigerantvalves are in service positions• Ensure that the unit is notdamaged• Ensure that sensors are properlyinstalled in their bulb-wells andsubmerged in heat conductingproduct• Check fixing of capillary tubes(protection from vibration andfrom wear) and ensure that theyare not damaged• Reset all manually set controldevices,• Check refrigerating circuitstightnessChecking and settingCompressors:• Check oil level at rest. The levelshould reach at least theminimum oil level on theindicator located on oilequalization line when thecompressors are OFF for apackaged unit (CGWN) and after10 minutes OFF time for a splitunit (CCUN with remotecondenser). See Figure 19 forcorrect level.• Check fixing of capillary tubes(protection from vibration andfrom wear) and ensure that theyare not damaged• Reset all manually set controldevices• Check refrigerating circuitstightness• Check electrical terminalstightening of the motors and inthe control panel• Check the isolation of themotors, using a 500V DCmegohmeter which meetsmanufacturer's specifications(minimum value 2 megohms)• Check the direction of therotation using phasemeterElectrical power wiring:• Check all the electrical terminalsare tight• Set-up compressors overloadrelays• Set-up fan-motors overloadrelaysElectrical control wiring:• Check all the electrical terminalsare tight• Check all the pressostats• Check and set-up the TRACERCH530 control module• Test and start-up without theelectrical powerCondenser:• Check setting of the safetypressure valve• Check the insulation of themotors using a 500V DCmegohmeter which meetsmanufacturer's specifications(minimum value 2 megohms)Figure 19 - Compressor oil level at oilequalization line121.
