CL-1,CL-2 SAFETY CONSIDERATIONS Installing and servicing air-conditioning equipment can be hazardous due to system pressure and electrical components. Only trained and qualified service personnel should install or service air-conditioning equipment. When working on air-conditioning equipment, observe precautions in literature and on tags and labels attached to unit. Follow all safety codes. Wear safety glasses and work gloves. Use quenching cloth for brazing operations. Have fire extinguisher available. Read these instructions thoroughly. Consult local building codes and National Electrical Code (NEC) for special installation requirements. WARNING: Before installing or servicing system, always turn off main power to system. There may be more than one disconnect switch. Electrical shock can cause personal injury. INSTALLATION The 575A090 unit uses a semi-hermetic compressor. See Table 1 for physical data. Cancels: II 575A-90-1 II 575A-90-2 12/1/95 The 575A090 outdoor unit is approved for use only with the 524A-H090 indoor unit. Use only approved indoor unit. The 575A090 unit is Underwriters’ Laboratories (UL) and UL Canada approved for use with the 524A-H090 indoor unit only. I. COMPLETE PREINSTALLATION CHECKS A. Uncrate Unit (See Fig. 1) Remove unit packaging except for the top skid assembly and wood bumpers, which should be left in place until after unit is rigged into place. B. Inspect Shipment File claim with shipping company if shipment is damaged or incomplete. C. Consider System Requirements • Consult local building codes and NEC for special installation requirements. • Allow sufficient space for airflow clearance, wiring, refrigerant piping, and servicing unit. See Fig. 2. • Locate unit so that outdoor unit airflow is unrestricted on all sides and above. Refer to Fig. 2. • Unit may be mounted on a level pad directly on base rails or mounted on raised pads at support points. See Fig. 2 for weight distribution based on recommended support points. • Provide for condensate drainage and defrost water disposal beneath unit. • Areas with high snowfall may need elevated mounting for adequate airflow. NOTE: If vibration isolators are required for a particular installation, use corner weight information in Fig. 2 to make proper selection.
