General Start-upCAUTION:For the warranty to apply, any startupcarried out directly by thecustomer must be recorded in adetailed report, which must be sentas soon as possible to your localTrane office.• Do not start-up a motor whoseinsulation resistance is less than2 megohms• Phase imbalance should not begreater than 2%.• The voltage supplied to motorsshould be within 5% of the ratedvoltage on the compressornameplate.• Excessive emulsion of the oil inthe compressor shows thatrefrigerant is present in the oiland the result will be thatcompressor is not lubricatedenough. Shut down compressorand wait for 60 minutes for thesump heaters to heat oil andstart again. Should this not work,consult Trane technician.• Excess oil in compressor candamage the compressor. Beforeadding oil, consult Tranetechnician. Use only productsrecommended by Trane.• The compressors must operatein a single direction of rotation. Ifrefrigerant high pressureremains stable in the 30 secondsafter compressor start-up,immediately shut down unit andcheck the direction of rotationusing phasemeter.Warning :The chilled water circuit may beunder pressure. Bring down thispressure before opening up thesystem to rinse out or fill up thewater circuit. Failure to comply withthis instruction may causeaccidental injury to maintenancepersonnel. If a cleaning solution isused in the chilled water circuit, thechiller must be isolated from thewater circuit to avoid all thedamage risks of the chiller andevaporator water pipes.Figure 20 - Standard units evaporator pressure drop10050EWPD (kPa)1051 2 3 4 5 6 71 - CGWN-CCUN 2052 - CGWN-CCUN 2063 - CGWN-CCUN 2074 - CGWN-CCUN 2085 - CGWN-CCUN 2096 - CGWN-CCUN 2107 - CGWN-CCUN 21111 5 10 50100EWFR : Evaporator Waterflow RateEWPD : Evaporator Water Pressure DropEWFR (l/s)34CG-SVX06A-E4
