IMPORTANT: This equipment generates, uses, and can radiate radio frequency energy. If not installed and used in accordance with these instructions, this equipment may cause radio interference. The equipment has been tested and found to comply with the limits of a Class A computing device as defined by the FCC (Federal Communications Commission, U.S.A.) Regulations, Subpart J of Part 15, which are designed to provide reasonable protection against such interference when operated in a commercial environment. INTRODUCTION These instructions cover installation of 30HX liquid chillers with electronic controls and units with factory-installed options (FIOPs). INSTALLATION Step 1 — Inspect Shipment — Inspect unit for damage upon arrival. If damage is found, file a claim with the shipping company right away. Do not store units in an area exposed to weather because of sensitive control mechanisms and electronic devices. Locate unit indoors. When considering unit location, consult National Electrical Code (NEC, U.S.A.) and local code requirements. Allow sufficient space for wiring, piping, and service. Install unit in an area which will not be exposed to subfreezing weather. See Fig. 1-8 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 unit is level and is capable of supporting the operating weight of the unit. See Fig. 9 and Tables 1A and 1B for unit mounting and operating weights. If necessary, add supporting structure (steel beams or reenforced concrete slabs) to floor to transfer weight to nearest beams. Step 2 — Rig and Place Unit Rig unit from the top heat exchanger only. Rigging from the bottom heat exchanger will cause the unit to be lifted unsafely. Personal injury or damage to the unit may occur. Copy continued on page 15. Manufacturer reserves the right to discontinue, or change at any time, specifications or designs without notice and without incurring obligations. Book 2 PC 903 Catalog No. 533-004 Printed in U.S.A.
