In addition to improving indoor air quality, economizers provide substantial energy savings by utilizing cool outside air instead of mechanical cooling whenever outside conditions permit. The outlet or discharge of the airside economizer is fitted to the return air inlet of the packaged air conditioning unit. The two inlets to the economizer are fitted to the return air and outside air ductwork. Opposed blade dampers located in each inlet modulate the incoming air streams as they enter the mixing box. The outside air damper can be maintained at a predetermined position. In this way the buildings ventilation requirements can be met at all times.

32 FORM EG2 (1211) SPECIFICATIONS Air-Cooled Self-Contained Units GENERAL All models 2-10 tons ship as a fully assembled, factory charged, packaged unit. Horizontal All models are designed for suspended mounting via integral structural channels. These units include refrigerant line shut-off valves between the condenser and evaporator section, allowing the unit to be field split and installed as separate modules to suit onsite requirements. Vertical All models are designed for free standing mounting on the floor, or on a field fabricated structural steel stand. The ton models are shipped as separate condensing unit and evaporator section modules for field assembly into a single packaged unit. The 3-10 ton models are shipped with vertical evaporator fan discharge as standard. The ton models are shipped horizontal discharge as standard. CABINET All cabinets are completely constructed of heavy gauge galvanized corrossion-resistant steel. The entire unit interior (both evaporator and condensing section) is insulated with 1/2" thick, 2-lb density insulation. Service panels are equipped with lifting handles for ease of removal and handling. Duct flanges for condenser discharge, condenser intake, and evaporator discharges are provided with the unit for field installation. Duct flange on evaporator return is incorporated into the filter frame. COMPRESSORS All models utilize high-efficiency Scroll type, R-410A, hermetic compressors. Compressors are mounted on rubber isolators to minimize vibration transmission. Internal motor overload protection is provided. External high pressure and low pressure cut-out switches are included in each compressor control circuit. Models 8 tons and larger have two individual scroll compressors. REFRIGERANT CIRCUITS Models 5 tons and smaller have a single refrigeration circuit. Models 8 tons and larger feature two independent refrigeration circuits. Each refrigeration circuit is thoroughly evacuated, and fully charged with R-410A refrigerant before shipment (12-20 ton models ship with a nitrogen holding charge only). Each refrigeration circuit includes an adjustable thermal expansion valve (with external equalizer), liquid line filter drier, sight glass/moisture indicator, a high refrigerant pressure safety switch, a low refrigerant pressure switch (for compressor protection), and service gauge ports. EVAPORATOR AND CONDENSER COILS The evaporator and condenser coils are constructed of internally enhanced copper tubes mechanically bonded to enhanced-surface aluminum fins. Both coils are employed in a draw-thru configuration. Large evaporator coil face area minimizes potential for water blow-off. INDOOR/OUTDOOR FANS Forward curved, double inlet and double width centrifugal blowers are used for both evaporator and condenser air movement. Blower wheels are fabricated of galvanized steel. Blowers employ solid steel shafts, supported in permanently lubricated ball bearings. All blowers are belt driven. Variable-pitch motor sheaves allow for field adjustment of blower rpm. Motor shall be 1750 RPM, open drip proof design. Three-phase motors are provided with external manual reset overload protection. Single-phase motors feature auto reset internal overloads. ELECTRICAL/CONTROLS All units are completely factory wired with all necessary controls. Current overload protection is provided on both evaporator and condenser motors (Internal autoreset overloads on single-phase units, external manual-reset overload on three-phase). All models come equipped with an electronic diagnostic compressor protection module. A flashing LED indicator is used to communicate alert codes. Phase protection and antishort cycle time delay protection is provided on each compressor circuit. Compressor will be locked out for 3 minutes when thermostat opens, or there is a momentary power outage. All units feature an auto-reset soft lock-out, on each compressor control circuit in the event of a high/low cut-out, and a manual reset hard lock-out due to multiple high/low pressure cut-outs. A 24 volt control circuit, with oversize transformer, is provided for field connection. 32 Johnson Controls
