STATEMENT OF WORK

Replace Vacuum Lines and Thermocouple (T/C) Pass-through Wiring for Tenney (SN 917) Autoclave System

1.0 Introduc�on/Background

Replace vacuum lines and thermocouple wiring of the Tenney autoclave (SN 917) in building 1238. This system has been showing signs of vacuum lines losing pressure and shorted channels with unstable readings. Of note, the thermocouple (TC) Jack in the autoclave was recently replaced so the pass through wiring is the main suspect for the cause of these issues.

2.0 Scope of Work

The work on the Tenney autoclave shall address the replacement of vacuum lines on Channels 1, 9, and 12 and TC pass-throughs on the system. This includes disconnec�ng and removing the current vacuum lines on Channels 1, 9 and 12, as well as the TC pass-through wiring in the autoclave, along with the installa�on of new pass-throughs, connec�ng the TC jacks, and checkout of vacuum lines and the T/C wiring.

3.0 Objec�ves

A�er comple�on of this work, the Tenney autoclave will have func�oning vacuum channels and stable thermocouple readings, thus elimina�ng erra�c T/C response. The new pass-through will help ensure adequate vacuum on all channels and accurate readings on T/C channels.

4.0 Descrip�on of the Work/Contractor Tasks

Tasks:

1. Disconnect vacuum lines and replace with new lines on Channels 1, 9 and 12.

2. Disconnec�ng the current Jack panel

The contractor shall unwire the current jack panel and the pass-through wires from the external terminal strips.

3.-Removal of TC Pass-Through The contractor shall disconnect the external wiring of the current pass-through(s) and remove the pass-through body from autoclave penetra�on. Careful inspec�on shall be made of the old pass-through wiring bundle(s) for any wire breaks, cuts, tears, rubbing, or other abnormali�es that could have contributed to earlier unstable and erra�c TC reading signals during autoclave cures.

4.-Installa�on of new passthrough A new pass-through wire bundle, Type J wire shall be installed in the vacant loca�on created by removing the old pass-through wire bundle(s). The new wiring shall be wired to the terminal bars in the junc�on box mounted outside on the clave chamber.

5.-Installa�on of Jack panel The newly installed pass-through wires shall be wired and secured to the twenty-four (24) TC jack connectors on the chamber’s interior jack panel.

6.-Verifica�on vacuum lines and calibra�on of T/C parts A�er comple�on of the above tasks the func�on of the vacuum channel lines and TC jacks and wiring shall be performed and documented.

All vacuum lines and exis�ng wiring (i.e., TC lead wires, Ground wires and connec�ons, etc.) that exits out of the exterior TC Junc�on box going to their final termina�on points (i.e., CSS300 cabinet, computer, PCI, etc.) shall be inspected for any defects, wire breaks, proper con�nuity, etc.) to help ensure accurate readings on the Part TC channels and alleviate erra�c TC response.

5.0 Deliverables

The contractor shall provide:

- The vendor should deliver what is listed above in 4.0 in 4.0Descrip�on of the Work/Contractor Tasks including Type J thermocouple pass through(s) with sufficient length and wire pairs for 24 thermocouple channels.

- Labor to remove vacuum lines on Channels 1, 9 and 12 and replace with new lines. Also to unwire and rewire and inspect the thermocouple jacks and their thermocouple connec�ons and wirings located outside the autoclave chamber.

- Any informa�on, documenta�on, drawings, etc. related to this maintenance service.

- Updated Calibra�on service and report for the TC channels.

STATEMENT OF WORK

Replace Thermal Couple (T/C) Pass-through Wiring and Jacks for TEC (SN399)

2.0 Introduc�on/Background

The thermocouple (T/C) pass-through wiring of the TEC autoclave (SN 399) in building 1238B has been in place for over twenty-five (25) years. The TC jack panel is also worn that it no longer holds the TC jacks securely in place. The TC wires in the pass through have been in place for many years as well.

2.0 Scope of Work

The work in this project shall address the replacement of all Twelve (12) of the interior part TC jack panel inputs of the TEC autoclave and replacement of the part TC pass-through wire bundle(s).

3.0 Objec�ves

A�er comple�on of this work, the TEC autoclave will have working TC jack inputs that will more securely hold Twelve (12) TC wire leads in their posi�on in the panel. The newly installed pass-through wires will help eliminate erra�c TC response and ensure accurate readings on the part TC channels.

4.0 Descrip�on of the Work/Contractor Tasks

Tasks:

1.Removal of current Jack panel The contractor shall dismount the current jack panel and disconnect the TC pass-through wires (cu�ng of wires okay because the wires are going to be replaced).

2.-Removal of TC Pass Through The contractor shall disconnect the external wiring of the current pass-through(s) from the disconnect and remove the pass-throughs from the autoclave penetra�on. Careful inspec�on shall be made of the old pass-through wiring bundle(s) for any wire breaks, cuts, tears, rubbing, or other abnormali�es that could have contributed to earlier unstable and erra�c TC readings during autoclave runs.

3.-Installa�on of new passthrough New pass throughs, Type J wire bundle(s), shall be installed in the vacant loca�on created by removing the old pass-through wire set. The new wiring shall be connected to the external extension wire routed to the data acquisi�on system.

4.-Installa�on of Jack panel Twelve (12) new thermocouple Type J female jack connectors capable of surviving autoclave temperatures of 700 degrees Fahrenheit and nitrogen pressures of 550psi shall be installed in the autoclave. Re-use of the old jack panel frame to mount the new TC jack connectors is acceptable.

5.-Verifica�on/calibra�on of Part TCs A�er comple�on of the above tasks, ring out of the TC jacks and wiring shall be performed and documented.

All exis�ng wiring (i.e., TC lead wires, Ground wires and connec�ons, etc.) that exits out of the exterior TC Junc�on box going to their final termina�on points (i.e., CSS300 cabinet, computer, PCI, etc.) shall be inspected for any defects, wire breaks, proper con�nuity, etc.) to help ensure accurate readings on the Part TC channels and alleviate erra�c TC response.

5.0 Deliverables

The contractor shall provide:

- The Vendor should deliver what is listed above in 4.0 Descrip�on of the Work/Contractor Tasks including Type J thermocouple pass-through(s) with sufficient wire pairs for 12 thermocouple channels.

- 12 – Type J very high temperature (700°F) female jacks

- Labor to replace and inspect the thermocouple jacks and the thermocouple pass through(s) and their connec�ons from the TC jack panel to the TEC computer, PCI, control cabinet, etc.

- Any informa�on, documenta�on, drawings, etc. related to this maintenance service for traceability and Configura�on Management, if later deemed required.

- Verifica�on report of the TC channels.
