2INSTALLATIONStorage — If the unit is to be stored for a period of timebefore installation or start-up, be sure to protect the machinefrom construction dirt. Keep protective shipping covers inplace until the machine is ready for installation.Step 1 — Place and Rig the UnitPLACING UNIT — Units are suitable for outdoor use only.For 30RAP010-060, see Fig. 2. When parallel chillers arealigned such that coils face each other, a minimum of 6 ft (1829mm) is recommended. When the parallel arrangement hasonly one coil drawing air from the space between chillers, aminimum of 3.5 ft (1067 mm) is recommended. When parallelchillers have no coils facing each other (a back-to-back ar-rangement), be sure to maintain the larger of the recommendedservice clearances associated with each chiller (see the certifieddrawings). Due to NEC (National Electric Code, U.S.A.) regu-lations, a minimum clearance of 4 ft (1219 mm) must be main-tained on the side of the chiller that has an electrical box. Chill-er fan discharge must be at least as high as adjacent solid walls.Installation in pits is not recommended.For 30RAP070-150, see Fig. 3. When chillers are arrangedin parallel, a minimum of 10 ft (3048 mm) between chillers isrecommended. Acceptable clearance on the cooler connectionside or end opposite the control box of the unit can be reducedto 3 ft (1 m) without sacrificing performance as long as the re-maining three sides are unrestricted. Acceptable clearance onthe side with a control box can be reduced to 4 ft (1.3 m) due toNEC (National Electric Code) regulations, without sacrificingperformance as long as the remaining three sides are unrestrict-ed. Clearances between chillers in dual chiller applications maybe reduced to 6 ft (1.8 m) without sacrificing performance pro-vided the remaining sides are unrestricted. For acceptableclearance with layout involving more than 2 chillers, pleasecontact application engineering.These instructions cover installation of 30RAP010-150 air-cooled liquid chillers. Refer to Fig. 4 for model number to de-termine factory-installed options.RIGGING — Preferred method for rigging is with spreaderbars from above the unit. Use shackles in lifting holes. Rig at asingle point with 4 cables for size 010-115 units, 6 cables forsize 130 and 150 units, or use spread bars. All panels must bein place when rigging. See rigging label on unit for details con-cerning shipping weights, distance between lifting holes, centerof gravity, and lifting ring dimensions. See Tables 1A and 1Bfor physical data. Refer to Fig. 5-8 for unit weights. SeeFig. 9A and 9B for rigging label.If overhead rigging is not possible, place chiller on skid orpad for rolling or dragging. When rolling, use a minimum of3 rollers. When dragging, pull the pad. Do not apply force tothe unit. When in final position, raise from above to lift unitoff pad.CAUTIONDO NOT re-use compressor oil or any oil that has beenexposed to the atmosphere. Dispose of oil per local codesand regulations. DO NOT leave refrigerant system open toair any longer than the actual time required to service theequipment. Seal circuits being serviced and charge withdry nitrogen to prevent oil contamination when timelyrepairs cannot be completed. Failure to follow these proce-dures may result in damage to equipment.6 ft(1.8 m)MINIMUM*3.5 ft (1.1 m)MINIMUM†* Minimum for when coils face each other.
