11MOUNTING UNIT — When unit is in proper location, useof mounting holes in base rails is recommended for securingunit to supporting structure, or for mounting unit on vibrationisolators if required. See Fig. 10-18. Fasteners for mountingunit are field supplied. Be sure unit is level to within 1/8 in. perfoot for proper oil return to compressor.Step 2 — Check Compressor Mounting — Asshipped, units with single compressors are held down with 4bolts through rubber grommets. All units with tandem com-pressors are held down with 6 bolts per pair through grommets.After unit is installed, verify mounting bolt torque 7 to10 ft-lb(9.5 to 13.6 Nm).For 30RAP100-150 units, RED bolts from compressormounting rail must be removed. These RED bolts are for ship-ping purpose only. Also remove the shipping braces that tie thecompressors in a circuit together. Using a 15-mm socket, loos-en each bolt and nut on each compressor tab and remove allbraces before unit start-up.Step 3 — Cooler Fluid and Drain Piping Con-nectionsALL UNITS — These chillers are supplied with factory-installed strainer (including blow-down valve) in the enteringfluid piping and flow switch in the leaving fluid piping. Flowswitch wiring is factory installed.Piping connections are located on the front of the chillerwhen facing the control panel for sizes 010-030 and at the endopposite the control panel for sizes 035-060. For sizes 070-150,piping connections are on the right side when facing the controlpanel and (Circuit B) of the chiller. See Fig. 10-15, dependingon model. See Fig. 16-18 for accessory storage dimensions.All sizes have Victaulic IPS connections as shown in thephysical data tables. The water connections are copper swagedto Victaulic IPS. Any connecting pipe to the 30RAP unit mustbe of a material that will not cause any galvanic corrosion. Forthis reason, galvanized steel pipe or other dissimilar metalsmust not be used unless joined by a dielectric coupling.Provide a means of venting air from the high point of thefield-installed piping as required. Install field-supplied drainsin both the entering and leaving fluid connections.After field piping is complete, freeze-up protection is rec-ommended using inhibited ethylene glycol or other suitable in-hibited antifreeze solution and electric heat tapes in areaswhere piping is exposed to low ambient temperatures (34 F[1° C] or below). Heat tapes should possess a rating for areaambient temperatures and be covered with a suitable thicknessof closed-cell insulation. Route power for heating tapes from aseparately fused disconnect. Identify disconnect as heat tapepower source with a warning that power must not be turned offexcept when unit is being serviced.Installation of water systems should follow sound engineer-ing practice as well as applicable local and industry standards.Improperly designed or installed systems may cause unsatis-factory operation and/or system failure. Consult a water treat-ment specialist or appropriate literature for information regard-ing filtration, water treatment, and control devices.CAUTIONDo not circulate water through unit without strainer inplace. Failure to use the strainer represents abuse and mayimpair or otherwise negatively affect the Carrier productwarranty.
