    Model A and BOpen Drive Compressors

    NOTE: The Model A and Bcompressors are offered onlyin the Series 6000 product line.DescriptionThe Trane Model A and Bcompressors are unloading, cast ironopen drive accessible compressors.The compressor oil pump isreversible for operation in eitherdirection. The compressor unloadingis suction pressure actuated.

    Basic VariationsThere is one optional basic variationto the A and B compressors: it isstandard compressor-right hand.This variation moves the unloaderhandhole cover, which also housesthe sightglass, to the right hand sideof the compressor, as viewed fromthe discharge valve end of thecompressor. This option is forconvenience of viewing the oilsightglass or access to the unloaderhandhole cover. It was also used onunits that had two compressors thatwere driven from a double extendedshaft motor. These units typicallyused a standard compressor and aright hand compressor.

    This variation will also allow the oilsight glass to be on the same side ofthe unit, should the compressor beapplied with a double extended shaftmotor.

    Lifting and HandlingBoth the A and B compressors havetapped holes in the housing that willaccommodate lifting lugs forhandling of the compressor. Duringhandling it is recommended that thecompressor be kept horizontal withthe cylinders heads facing up. Thiswill prevent oil from getting into theupper cylinder and causing potentialdamage when the compressor is

    started. If tilted from horizontal, it isrecommended that the compressorbe allowed to set in the horizontalposition a minimum of one hourbefore trying to start the compressor.

    StorageThe compressors are shipped with anitrogen charge and the connectionsare sealed with closure plates; unlessthe optional service valves have beenordered for factory installation. Thestorage of the compressor must be inan enclosed dry space with thetemperature and humidity not toexceed 140 F and 95% RH noncondensing.

    Mounting and VibrationIsolationMountingSince the Model A and Bcompressors are open drive units,the compressor must not bemounted on isolators. Thecompressor along with its primedriver should be mounted on acommon base. The common basecan then be isolated as an assemblyfrom the rest of the unit if desired.

    The mounting pads for thecompressor and the prime movermust be flat to provide a surface forproper alignment and shimming ofthe compressor and prime driver.The base must also be rigid toprevent the compressor shaft andmotor shaft from flexing duringoperation. If flexing occurs, couplingmisalignment will occur and result ina failure of the crankshaft. Angularand parallel alignment should notexceed 0.010 inches total indicatedreading. See the coupling section forthe alignment of the coupling. Thecompressor mounting feet have.5625 inch diameter holes formounting.

    Refrigeration ConnectionsService ValvesBoth the A and B compressors aredesigned to accept optional servicevalves and are designed for sweatconnection utilizing a brassconnection. The service valves boltdirectly to the compressor. Therefrigerant connection size for theindividual compressor model is listedon the compressor dimensional datasheets. Whenever brazingrefrigerant piping, use a nitrogenpurge to prevent the formation ofcopper oxides. The presence ofcopper oxides in the compressor isdetrimental to the reliability of thecompressor.

    Pressure TestingThe maximum highside test pressureis 300 psig. The maximum lowsidepressure is 200 psig. The differentialbetween highside and lowsideshould not exceed 300 psig. Neverexceed the pressure setting of anyrelief valves that may be installed inthe system.
