38AUZ / 38AUD Air Cooled Condensing Unit Puronr (R---410A) Refrigerant 6 to 20 Nominal Tons Product Data FEATURES/BENEFITS These dependable outdoor air cooled condensing units match Carrier’s indoor-air handlers to meet a wide selection of cooling solutions. Constructed for long life C09227 38AUZ07- 14 shown - the environmentally sound refrigerant The 38AUZ single circuit and 38AUD dual circuit, scroll compressor models are designed and built to last. The high efficient designed outdoor coil construction allows for a more efficient design in a smaller cabinet size that utilizes an overall reduction in refrigerant charge. Where conditions require, special coil coating coil protection option is available. Cabinets are constructed of prepainted galvanized steel, delivering unparalleled protection from the environment. Inside and outside surfaces are protected to ensure long life, good looks, and reliable operation. Safety controls are used for enhanced system protection and reliability. Each unit utilizes the Comfort Alert diagnostic and troubleshoot control system. This protects the units operation and provides valuable diagnostic information when required. Factory-installed options (FIOPs) Carrier’s air-cooled air conditioning split systems: S provide a logical solution for commercial needs S have a rugged, dependable construction S are available in single and circuit scroll compressor capacity control S have cooling capability up to 125_F (52_C) ambient and down to 40_F (4_C) ambient standard Certified and pre- engineered factory-installed options (FIOPs) allow units to be installed in less time, thereby reducing installed cost. FIOPs include: S low ambient controls which provide cooling operation down to - 20_F (- 29_C) ambient temperatures S non-fused disconnect S 115-v GFI (ground fault interrupter) convenience outlet, powered and non- powered available S special coil coating coil protection S louvered hail guard

FEATURES AND BENEFITS (cont.) Efficient operation These air cooled condensing units will provide EER’s up to 11.2 which meets both ASHRAE and Energy Star efficiency levels. applications and provide positive drainage and prevent standing condensate. Controls for performance dependability 38AU This high efficiency will help reduce overall operating cost and energy consumption. The accessory economizer can provide ventilation air to improve indoor-air quality by using demand control ventilation. When used in conjunction with Carrier Comfort System and CO2 sensors, the economizer admits fresh outdoor...
