Enclosed please find copies of American Warming &
Ventilating, Inc., Customer Notifications concerning the subject 10 CFR 21 for AW Job No's: 80290, 90083, 90084, 90096, 90120, 90121, 90162, 90163, 90181, 90186, 90193, 90216, 90235 and 90236.
Please be advised that:
- 1) AWV jobs 90096 and 90216 are classified as Non-Nuclear Safety Related Dampers. Consequently, it is AWV's o" pinion that these dampers do noc fall under-the reporting requirements of 10 CFR 21 and as such are removed from AWV's list of affected Customers and Projects, (Attachment to February 6,1980 Notifi-cation and revised March 19, 1980), revised copy enclosed.
- 2) AW is retract;ing all reference to AWV jobs 90084, 90120, 90121, and 90263 concerning the subject 10 CFR 21. In these instances the ITT-GC Actuators were provided by the Purchaser to AW for in-stallation on to dampers sold. As such, the Purchaser has the responsibility to provide ITT-GC Actuators which meet the torque requirements of the damper and/or subject specification. These jobs are removed from AW's list of Affected Customers and Projects, as described in 1).

If more torque is needed, N W suggest thatfButfalo Forge send the actuators back te ITT for ITT to'actually, test,the units in ques tion. ITT vill then return the actuators'with the actual g documented thrust valves. These thrust valves can be converted intotorquevalvesbymultiplyingthethrustvalvelby1.75.

.ITT actuators which by the statistical data can not be shoten to meet the torque requirements of the damper and/or your specification. It is, however, thought that the actuators on these dampers actually do have sufficient force based on other actual actuator force date. in order to prove this the actuators will have to be returned to ITT General Controls for actual testing. .

This should al~ low a reasonable judgement to be made concerning.the capability of the actuator to perform as expected-Note, the statistical. data' include's the lowe'r minimum force value exerted by a number one (1) spring manufactured from an incorrect material; reference 3. ITT General Controls maintains that once such a numcer one (1) spring is. compressed it will thereafter consistently exert the same force level without. l degredation. ~ ITT General Controls has advised that their Engineering Department is preparing a complete report for the basis of the data supplied. This report will be sent to you within seven ! (7) working days of its receipt. AWV should be receiving this

Prior to AWV taking any corrective action on this matter, he ITT General Controls Engineering Report must be accepted and i approved; the data used for this evaluation must be considered preliminary in the meantime.
