24Step 3 — Separate Machine Components —The design of the 23XRVchiller allows for disassembly at thejobsite so that the individual chiller components may bemoved through existing doorways. Use the following proce-dures to separate the machine components.Suggested locations to cut piping will minimize the width ofthe condenser/economizer assembly.SEPARATE COOLER AND CONDENSERNOTE: For steps 1 through 13 refer to Fig. 17 for units with Qor R compressors, or Fig. 18 for units with P compressors. Thecooler in Fig. 17 has been removed from the picture to showthe pipes and lines that must be cut.Check that the holding charge has been removed from thechiller.1. Place a support plate under each tube sheet to keep eachvessel level (does not apply to units with P compressor).2. Remove cooler relief valve and relief valve vent piping(cooler not shown in Fig. 17 or 18, see Fig. 3, 4, or 5).3. Cut the motor cooling refrigerant drain line (see Fig. 17,item 4) (does not apply to units with P compressor).4. Unbolt and rig the suction elbow off (does not apply tounits with P compressor) and disconnect the compressorsuction line at the cooler and compressor. Remove boltsfrom the vaporizer vent line flange.5. Cut the VFD cooling drain line (see Fig. 17, item 11)(does not apply to units with P compressor).6. Cut the oil reclaim line(s) (see Fig. 17, item 12, or Fig. 18,item 10) .7. Cut the hot gas bypass line between the HGBP (hot gasbypass) solenoid valve and cooler feed line (see Fig. 17,item 10, or Fig. 18, item 11).8. Cut or unbolt the cooler liquid feed line (see Fig. 17, item9, or Fig. 18, item 3), near the economizer or condenserfloat chamber at the flanged connection. For economizedunits with Q or R compressors, temporarily secure the in-line economizer orifice plate to the economizer flange.CONDENSERPRESSURECABLEHOT GASBYPASSCABLESECONOMIZER PRESSURESENSOR CABLE ANDECONOMIZERTEMPERATURESENSOR CABLEa23-1686FRONT VIEWa23-1687EVAPORATOR LEAVINGLIQUID TEMPERATURESENSOR CABLEEVAPORATOR ENTERINGLIQUID TEMPERATURESENSOR CABLECONDENSER LEAVINGLIQUID TEMPERATURESENSOR CABLECONDENSER ENTERINGLIQUID TEMPERATURESENSOR CABLEEND VIEWOIL PUMPCONDUIT OIL DISCHARGEPRESSURESENSOR CABLEOIL SUMPPRESSURECABLE OIL SUMPTEMPERATURESENSOR CABLEOIL HEATERCONDUITEVAPORATORSATURATEDTEMPERATURESENSOR CABLETEMPERATURESENSORCABLECOOLERPRESSURECABLEFig. 16 — Electrical Cable Routing (Unit with P Compressor Shown)BACK VIEWIMPORTANT: If the cooler and condenser vessels mustbe separated, the heat exchangers should be kept levelby placing a support plate under the tube sheets. Thesupport plate will also help to keep the vessels level andaligned when the vessels are bolted back together.
