SAFETY CONSIDERATIONSInstallation, start-up and servicing of this equip-ment can be hazardous due to system pressures,electrical components and equipment location .(roofs, elevated structures, etc.).Only trained, qualifal installers and service;,-mechanics should install, start-up and service ,thifequipment.When working on the equipment, observe pre-cautions in the literature, tags, stickers and labelsattached to the equipment and :to any other safetyprecautions 'that apply.• Follow all safety codes.• Wear safety glasses and work gloves.Carrier Parkway ! _Syracuse, N.Y. 13221-Reciprocating uid ChillersFor Model D Univ-.

If necessary, add sup-mrting structure (steel beams or reinforced concreteto floor to transfer weight to nearest beams.Figure 1 shows location of 6 mounting holes.• Each point supports approximately 1/ 6 of theoperating weight.Do not remove unit from skid until it is in finallocation. Rig from the 2-in. diam holes in the coolerend flanges. Lower carefully onto floor or rollers.Push or pull only on the skid, not the unit. If theunit is moved on rollers, use a minimum of 3,evenly spaced.Areas where corners will be located must be level*before unit is placed. Level unit with spirit level onframe channels. Bolt to floor (recommended forbasement or ground floor installations that transmitvibration to ground without affecting buildingstructure).All compressors have mufflers and are attachedrigidly on top of rails mounted on spring vibration _isolators. Remove rail mounting bolts so rails float_freely on springs. If bolts are not removed, theymay retighten from vibration during operation.Interconnecting piping must be flexible enoughto prevent vibration transmission. If vibration stilloccurs, use isolators on unit. If installation is onupper, floor where vibration cannot be transmittedto the ground, use field-purchased isolator springsunder each unit mounting hole.• Use care in handling, rigging and setting bulkyequipment.INSTALLATIONLOCATIONDo not store -u s in an area exposed to weatherbecause of sensitive control mechanisms and elec-trical ileviCes.
