Based upon information accumulated by Trentec, Inc., it has been determmed that a number of capacity control valves purchased from York International as commercial grade items and dedicated for safety-related use by Fanvell & Hendricks, Inc. (prior to being acquired by Trentec,Inc.) were subsequently found to contain a manufacturing l

defect. The manufacturing defect is due to improper machining of the holes in the valves, as indicated in the anached correspondence between Trentec and York International. The York International Part Numbers for this valve are: 3C t-21538 000(when purchased as a single item) and 064-20838C (as a subcomponent of a compressor).

Valves of this type were supplied as safety-related to Baltimore Gas & Electric Co. Il Trentec bas been in contact with that utility regarding this condition, and return of the potentially defective valves has been requested in order to replace any improperly machined parts. At the present time, there is no indication that any of the defective 7/

valves have been installed in safety-related systems, however further information will be obtained from the utility in the immediate future to confirm the status of the supplied valves.

Respectfully, j r V

FAX 9 September,1998 To: Brian Miracle, Trentec (513) 528-9292 From: Mark Sievert, York Imemational (717) 337 1440 Re: York Capacity control Valves All capacity control valves (subcomponent P/N 064-20838C) in inventory here at York PA and at the Ycrk Parts cemer in Baltimore have been checked for the incorTect machining (location) of holes as you described in your letter of 19 August. One part was found with the defect. This pan has been scrapped. All others met the drawing.

This is a specialty part, not manufactured in production with fixtures, but custom machined in our specialty machine shop. If any discrepam parts were built into compressors, the compressor would function, but would not load / unload. Customer operators would not be able to switch from 4 cylinders to 6, or vice versa, indicating a bad pan.. The specialty machine shop personnel have been made aware cf the problem; and we will continue to monitor field operations for compressors in this condition.

Thank you for your assistance. Please contact me at (717) 771- 6284 if you have further questions.
