Replace the Two Male Fittings in the Waste Drawer that Connect to the Waste Bottle

What is Affected

The current polypropylene fittings have been found to degrade due to exposure to bleach. Over time the bleach can cause these fittings to crack under stress, resulting in spillage, possible contamination and low vacuum failures. The new fittings are made from Polysulfone. This material is known to have better material compatibility with bleach.

Parts and Materials Required

• Proper PPE
• Adjustable Wrench
• Waste Bottle CPC Coupling

  Note—Make sure to order 2 if you need to replace the 2 fittings.

  

Time Required

• 20 Minutes

Procedure

1. Put on proper PPE.
2. Power down the Panther System.
3. Open the Waste Drawer.
4. Use an adjustable wrench to remove the 2 existing CPC waste bottle couplings in the drawer.

   

5. Install the new Polysulfone CPC waste bottle couplings.
6. Put the waste bottle back in the drawer.
7. Close the waste drawer.
8. Loosen the CPC fitting block mounted to the drawer and adjust it.
9. Make sure the fittings are fully engaged and that the waste bottle is sitting flat in the drawer.
10. Tighten the block to the drawer.

Verification

1. Power on the Panther System.
2. Open the Panther GUI.
3. Monitor the vacuum pressure through the Panther GUI.
4. After 5 minutes the Panther vacuum pressure should settle into a range of 7 in/Hg +/- 1 in/Hg.
5. Verify that the system can successfully pass prime.
