The new sensor is located in the inlet cone (illustrated in the diagram). The older sensor (before 3/03) was located in the suction elbow. 6 Beginning 3/05 the CS05 sensor was redesigned to use a well. The location remained the same. From 3/03 to 3/05 no well was used. 7 This cable was used with the original operator interface panel. The new flat screen panel uses a VGA cable & a serial cable which come with the panel.

40 Compressor High Speed Assembly Pinion, Thrust Pump, High Speed Bearings, Seals Diagram Original Design: Until 10/03 (italicized parts have changed and are no longer available. If any one of these are required, all must be retrofitted) Current Design: 10/03 and later NOTE: In late September, 2003 the rear high speed assembly was redesigned. Both designs are shown for reference, however only the current design may be used for replacement parts. The parts involved in the redesign are indicated in the Original Design diagram with italicized reference bubbles. Original and new design affected (italicized) parts DO NOT interchange, and older design parts are no longer available. Replacement of any of the affected parts on a unit built prior to 10/03 requires retrofitting the assembly with ALL redesigned parts RPL / Page 40
