Vacuum Pump/Cooling Module Fuse Upgrade Procedure

What is Affected

The vacuum pump is connected to the cooling module PCB. In rare cases of a short or an electrical issue with one or the other module, both modules could be affected. This upgrade will integrate an in-line fuse in the electrical line, bridging both modules to help isolate them in cases of electrical issues.

Parts and Materials Required

• Proper PPE

• Allen wrench, 3 mm
• FUSE BOX ASSEMBLY, VACUUM HOUSING

Time Required

• 15 minutes

Removal Procedure

1. Put on proper PPE.
2. Power down the Panther System and prepare it for service.
3. Open the Universal Fluids Drawer to its fully extended position and open the right side panel.
4. Locate the Cooling Module.

   

5. On the Cooling Module PCB, locate the vacuum pump connector to the PCB.

   

6. Unplug the vacuum pump wiring harness from the Cooling Module PCB.
7. Plug the new part (FUSE BOX ASSEMBLY, VACUUM HOUSING) into the now vacant vacuum pump connection on the PCB.
8. Connect the vacuum pump wiring harness into the fused end of the fuse box assembly.

   

   Note—Use a zip tie to secure any excess wire. Unsecured wires could potentially get stuck on moving parts of the system, such as the Universal Fluids Drawer.

9. Close the right side panel and the Universal Fluids Drawer.
10. Power on the Panther System.
11. Verify full system reset and that the vacuum level is within range.
