13 Separate Mac hine Components — The design of the 23XR V allows for disassembly at the job site so that individual components may be moved through existing door- ways. Use the following procedur es to separate the machine components. Suggested locations to cut piping will minimize the width of the condenser/economizer assembly .
14 9. Cut the vaporizer refrigerant return line as shown. 10. Disconnect all sensors with cables that cross from the condenser side of the machine to the cooler side including: a. Evaporator refrigerant liquid temperature sensor . See Fig. 13. b. Entering and l eaving chiller liquid te mperature sensors.
15 3. Remove the nuts that secure the terminal box transition piece to the motor housing. 4. Disconnect the motor leads from the motor terminals (Fig. 17). Note the position of the motor terminal cable lugs so they can be reinstalled with suf ficient clearance away from surrounding structure.
16 Lifting the Control Center — Care should be used to prevent damage due to dropping or jolting when moving the control center . A fork truck or similar means of lifting and transporting may be used. Sling in a manner that will equalize the load at the pickup points.
17 SEP ARA TE THE COMPRESSOR FROM THE CONDENSER The VFD blocks access to the compressor mounting bolts. It must be removed before th e compressor can be separated from the condenser . See instruc tions to remove the VFD from the condenser . Refer to T able 10.
18 Table 10 — Comp ressor Fastener Ide ntification 1. Disconnect the oil supply line in two places (Fig. 23). Cap the oil lines and fittings. NOTE: Compressor oil lines and fittings between the oil filter and compressor must be kept extremely clean to prevent obstruction of the compressor inlet bearing oil orifice.
19 SEP ARA TE THE V APORIZE R FROM THE CON- DE NS ER — The VFD mounting brackets (Fig. 24) extend beyond the outboard edge of the vaporizer . The vaporizer extends beyond the perimeter of the condenser tubesheet. 1. Cut the vaporizer hot gas supply line near the oil concen- trator (Fig.

22 Insulate Motor T e rminals and Lead W ire Ends — Locate heat shrink tubing (RCD P/N LF33MM1 14) over power connections so that they are completely covered and tubing is against motor housing. Shrink into position. Slide foam tubing (3 in. inner diameter closed cell vinyl, neoprene, or nitrile foam) pa rt way over the heat shrink tubing.
23 INST ALL ACCESSOR Y ISOLA TION (if required) — U n- even floors or other considerations may dictate the use of accessory soleplates (supplied by Carrier for field installation) and leveling pads. Refer to Fig. 33. Level machine by using jacking screws in isolation sole- plates.
24 5. Remove jacking screws fr om leveling pads after grout has hardened. INST ALL SPRING ISOLA TIO N Spring isolation may be purchased as an accessory from Carrier for field installation. It may also be field supplied and installed. Spring isolators may be placed directly under machine support plates or located under machine soleplates.
