Only trained, qualified installers and servicemechanics should install, start up, and service this equipment. When working on the equipment, observe precautions in theliterature, 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 bulky equipment. WARNING Electrical shock can cause personal injury and death. Shutoff all power to this equipment during installation. Theremay be more than one disconnect switch. Tag all disconnect locations to alert others not to restore power until workis completed. IMPORTANT: This equipment generates, uses, andcan radiate radio frequency energy and if not installedand used in accordance with these instructions maycause radio interference. It has been tested and found to comply with the limits of a Class A computingdevice as defined by FCC (Federal CommunicationsCommission, U.S.A.) regulations, Subpart J of Part 15, which are designed to provide reasonable protectionagainst such interference when operated in a commercial environment. INTRODUCTION These instructions cover installation of 30XA080-500 air- cooled liquid chillers with electronic controls and units withfactory-installed options (FIOPs). See Fig. 1. INSTALLATION Storage — If the unit is to be stored for a period of time before 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 — Inspect Shipment — Inspect unit for damage upon arrival. If damage is found, immediately file a claimwith the shipping company, and contact your local Carrierrepresentative. Manufacturer reserves the right to discontinue, or change at any time, specifications or designs without notice and without incurring obligations. Catalog No. 04-53300026-01 Printed in U.S.A. Form 30XA-10SI Pg 1 11-09 Replaces: 30XA-5SI Step 2 — Place, Mount, and Rig the Unit — When considering a location for the unit, be sure to consultNEC (National Electrical Code, U.S.A.) and/or local coderequirements. Allow sufficient space for airflow, wiring, piping, and service. See Fig. 2-14. NOTE: To facilitate refrigerant vent piping, all units have fusible plugs with 1/4 in. SAE (Society of Automotive Engineers) flares and pressure reliefs with 3/4 in. NPT fittings (if required by local codes). PLACING UNIT — Locate the unit so that the condenser airflow is unrestricted both above and on the sides of the unit. Airflow and service clearances are 6 ft (1.8 m) around the unit. Acceptable clearance on the sides or ends without control boxescan be reduced to 3 ft (1 m) without sacrificing performance aslong as the remaining three sides are unrestricted. Acceptableclearance on the side with a control box can be reduced to 4 ft (1.3 m) due to NEC regulations, without sacrificing performanceas long as the remaining three sides are unrestricted. Provide ample room for servicing and removing the cooler. See Fig. 2-14 forrequired clear...
