Only trained, qualifiedinstallers and service mechanics should install, start up, andservice this equipment.When working on the equipment, observe precautions inthe literature, and on tags, stickers, and labels attached to theequipment.• Follow all safety codes.• Wear safety glasses and work gloves.• Use care in handling, rigging, and setting bulkyequipment.INTRODUCTIONThese instructions cover installation of 30HX liquid chill-ers with electronic controls and units with factory-installedoptions (FIOPSs).IMPORTANT: This equipment generates, uses, and canradiate radio frequency energy. If not installed andused in accordance with these instructions, this equip-ment may cause radio interference. The equipment hasbeen tested and found to comply with the limits of aClass A computing device as defined by the FCC(Federal Communications Commission, U.S.A.) Regu-lations, Subpart J of Part 15, which are designed toprovide reasonable protection against such interfer-ence when operated in a commercial environment.INSTALLATIONStep 1 — Inspect Shipment — Inspect unit for dam-age upon arrival. If damage is found, file a claim with theshipping company right away. Do not store units in an areaexposed to weather because of sensitive control mecha-nisms and electronic devices.Locate unit indoors. When considering unit location, con-sult National Electrical Code (NEC, U.S.A.) and local coderequirements. Allow sufficient space for wiring, piping, andservice. Install unit in an area which will not be exposed tosubfreezing weather. See Fig. 1-4 for clearance details.Allow the following clearances for service access:Front . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 3 ft (914 mm)Rear . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 3 ft (914 mm)Top . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 2 ft (610 mm)Ends . . . . . . . . . . . . . . . tube removal at one (either) end;3 ft (914 mm) at opposite end.Be sure surface beneath the unit is level and is capable ofsupporting the operating weight of the unit. See Fig. 5 andTables 1A and 1B for unit operating weights. If necessary,add supporting structure (steel beams or reinforced concreteslabs) to floor to transfer weight to nearest beams.Step 2 — Rig and Place UnitRig unit from the top heat exchanger only. Rigging fromthe bottom heat exchanger will cause the unit to be liftedunsafely. Personal injury or damage to the unit mayoccur.Do not remove unit from skid until unit is in itsfinal location. Rig from the rigging holes provided in the topheat exchanger. See Fig. 1-5 for rigging and center of grav-ity information. Lower the unit carefully onto the floor orroller. Push or pull only on the skid, not the unit. If theunit is moved on rollers, use a minimum of 3 evenly-spacedrollers.Copy continued on page 9.30HXA,HXC076-186Water-Cooled and Condenserless Chillers50/60 HzManufacturer reserves the right to discontinue, or change at any time, specifications or designs without notice and without incurring obligations.Book 2Tab 5cPC 903 Catalog No. 563-052 Printed in U.S.A.
