All other operations should be performed by trained service personnel. When working on equipment, observe precautions in the literature and on tags, stickers and labels attached to the equipment. • Follow all safety codes • Wear safety glasses and work gloves Keep quenching cloth and fire extinguisher nearby. • Use care in handling, rigging and setting bulky equipment. A WARNING To avoid electric shock and personal injury, be sure power to equipment is shut off before performing maintenance or service. INSTALLATION IMPORTANT: Follow unit location, clearances and piping requirements in this booklet carefully to enhance system efficiency, and to avoid system1 failure Read entire booklet before starting installation. Step 1 — Complete Pre-Installation Checks INSPECT SHIPMENT — Immediately file claim with shipping company if shipment is damaged or incomplete. CONSIDER SYSTEM REQUIREMENTS • Consult local building codes and National Electrical Code (NEC) for special installation requirements.

See Fig. 1. • Locate unit so that condenser airflow is unrestricted on all sides and above. • Unit has legs for mounting on level pad. See Fig. 2 and Table 1 for weight distribution based on recommended support points. NOTE: If vibration isolators are required for a particular installation, use the data in Table 1 and Fig. 2 to make proper selection. Step 2 — Rig and Locate the Unit A CAUTION RIGGING — Lift units at points 3, 4, 7, 8 (Fig. 2). Use eyebolts and washers supplied in parts package. Do not sling unskidded unit. Skidded unit may be slung provided sling does not contact sides of unit. While unit is on skid, it can be rolled or dragged.

Provide clearance around the unit as shown in Fig. 1. Remove 6 hold-down bolts, releasing skid. The legs are attached to base skid. Block up or suspend unit. With bolts supplied, secure legs (see Fig. 5) to unit (1, 2, 3, 4, 5 and 6 in Fig. 2 and Table 1).

Weight distribution shown in Fig. 2 will determine type of support required. Bolt unit securely to pad or supports when positioned and leveled. Step 3 — Mount Compressor COMPRESSOR MOUNTING — As shipped, the compressor is held down by special self-locking bolts and lockwashers. After unit is installed, remove self-locking bolts one at a time and reassemble with flanged washers and neoprene snubbers as shown in Fig. 4. The flanged washers and neoprene snubbers are shipped in a cloth bag tied to one of the compressor feet. Tighten all 4 bolts, then loosen each until the flanged washer can be moved sideways with finger pressure. Step 4 — Complete Refrigerant Piping Connections SIZE REFRIGERANT LINES — Consider length of piping required between outdoor and indoor units, amount of liquid lift and compressor oil return. Refer to Part 3 of Carrier System Design Manual for line sizing information. Refer to indoor unit installation instructions for additional information. Maximum liquid line length is 100 feet. Carefully determine the minimum expected unit capacity and size interconnecting lines accordingly. For low load conditions, determine if there is a need for double suction risers per Carrier System Design Manual. Consider vapor line as hot gas line. Consider line sizes for heating as well as cooling capacities. A CAUTION Piping must be properly sized and installe...
