CL-1,CL-2 SAFETY CONSIDERATIONS Installing, starting up, and servicing air-conditioning equipment can be hazardous due to system pressures, electrical components, and equipment location. Only trained, qualified installers and service mechanics should install, start-up, and service this 09BY equipment (Fig. 1). When working on the 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 when brazing. Use care in handling, rigging, and setting bulky equipment.

GENERAL The 09BY air-cooled condenser is a remote air-cooled condenser designed to be used with the 50BZ vertical packaged units. See Table 1. Airflow is horizontal, both into and out from the same face of the unit. The unit is designed to be mounted indoors in a window, through the wall in high-rise buildings, or on the wall on the building exterior. See Fig. 2 for typical applications. Ductwork is not needed, but may be added easily if required by the application. Airflow is provided by centrifugal fans with an adjustable belt drive to meet varying static requirements. Units may also be matched with other compressor and evaporator combinations. Contact your local representative for more details. Check space requirements, service clearances, floor strength, location of piping, size of power supply, and location of duct- work (if used) before installing. See Fig. 3 for unit dimensions and Table 2 for unit operating weights. INSTALLATION Step 1 — Complete Pre-Installation Checks — Examine unit for damage incurred during shipment. File claim immediately with transit company if damage is found. Check the shipment for completeness. Verify that the nameplate electrical requirements match the available power supply. Manufacturer reserves the right to discontinue, or change at any time, specifications or designs without notice and without incurring obligations.
