DBC 3" Series Dry Disconnects Reassembly Prior to reassembly, inspect all components for damage especially scratches to the sealing surfaces. Pay close attention to the BODY, POPPET, SEAL CYLINDER, STUFFING BOX, and main SHAFT. If you are re-using any seals, inspect them to make sure there are no cracks or locations showing wear. - Page 7 DBC 3" Series Dry Disconnects 8. Press new guide BUTTONS into the outside diameter of the SEAL CYLINDER and apply a liberal coating of grease to the SEAL CYLINDER outside diameter. - If unit uses a PTFE NOSE SEAL, insert that NOSE SEAL into the end of the SEAL CYLINDER.

Page 9: Test Procedure
DBC 3" Series Dry Disconnects 31. While holding the coupler BODY firmly, push the LEVER towards the open position and allow the coupler to open itself using the spring force against the SEAL CYLINDER. The coupler should ‘snap’ to the open without delay and the SEAL CYLINDER movement should remain in contact with the POPPET movement. - Page 10 DBC 3" Series Dry Disconnects 8. Remove all pressure from the coupler and remove from the water. 9. Install a Dry Disconnect Adapter equipped with a plug in its threaded end. Make sure both CAM ARMS are closed and locked. 10.
