Unit frames are constructed of 14 gauge welded galvanized steel with 14 and 16 gauge galvanized steel panels and access doors. The unit surface is phosphatized and finished with an air-dry paint to withstand 672 hours of continuous salt spray solution in accordance with ASTM B117. Decorative louvered panels provide condenser coil protection. Compressors Trane 3-D Scroll compressors have simple mechanical design with only three (3) major moving parts. Scroll type compression provides inherently low vibration. 3-D compressors provide a completely enclosed compression chamber with no leakage paths. The compressor is suction gas cooled, direct drive, 3600 RPM hermetic motors. The Scroll compressor includes a centrifugal oil pump, oil level sight glass, and an oil charging valve. Refrigerant Management Split systems can have significantly more refrigerant than packaged systems and thus require controls to reliably manage this excess refrigerant. Each compressor shall have crankcase heaters installed, properly sized to minimize the amount of liquid refrigerant present in the oil sump during off cycles. Additionally, the condensing unit shall have controls to initiate a refrigerant pump down cycle at system shut down on each refrigerant circuit. To be operational, the refrigerant pump down cycle requires a field-installed isolation solenoid valve on the liquid line near the evaporator. Unit Control Factory provided 115-volt control circuit includes fusing and control power transformer. The unit is wired with magnetic contactors for compressor and condenser motors, three-leg solid-state compressor overload protection, and high/low pressure cutouts. Charge isolation, reset relay and anti-recycle compressor timer is provided. Across-the- line start is standard. Dual Circuit, Aluminum Fin Condenser Coils for 40-60 Ton Units Condenser coils are dual circuited having configured aluminum fins mechanically bonded to copper tubing with an integrated subcooler per circuit. The coils are burst tested and leak tested underwater at 450 psig [3102.8 kPa]. Factory installed liquid line service valves are standard. Condenser Fans Condenser fans are direct driven with motors having thermal overload protection and permanently lubricated ball bearings. Dual Refrigerant Circuit w/Four Capacity Stages for 40-60 Ton Units Each unit has dual refrigeration circuits. Each circuit has two (2) compressors manifolded together utilizing a passive oil system. Each unit has four capacity stages. Capacity modulation is accomplished by turning compressors on and off. Variable Air Volume Control Supply air variable air volume control provides a Honeywell W7100A control system. This option is for use with shutoff variable air volume or other applications requiring control of supply air temperature. The control provides a voltage output for interface with field supplied components to provide simultaneous economizer operation. This discharge air sensor ships with the unit for field mounting. The standard variable air volume unit is provided with reliable coil frost protection in the form of Trane's proven and patented Frostat. Frostat is used in place of hot gas bypass. Low Ambient Control Low ambient option extends unit operation from 40 F to 0 F [4.5 to -17.8 C] by utilizing an external damper assembly for head pressure control. Suction Service Valve This valve isolates the compressor for servicing. The valve is a refrigerant shut off valve.
