To use the Vented Cable Blowout Fitting:
- Remove the storage caps from both ends of the Vented Cable (remember to save the caps). Or if deployed, remove the logger and Wellhead.
Do not twist the Blowout Fitting, Vented Cable or stainless steel cable connector body when connecting to the fitting. Only twist the stainless steel coupling.
- Connect one end of the Vented Cable to the correct connection on the Blowout Fitting. Ensure proper alignment before pushing the connection together.

the Vented Cable
- Slowly apply 25-30 psi of nitrogen gas to the Vented Cable. Let pressure flow through the cable for about 5 minutes. If you hear no air flow, you can apply up to 50 psi of pressure to clear any blockages.
- Turn off the nitrogen gas flow and remove the Vented Cable from the Blowout Fitting.
- If deploying the datalogger, immediately connect one end of the Vented Cable to the logger, and the other to the Wellhead. See Section 1.5.1 for connection instructions.
- If storing the Vented Cable, immediately install the storage caps to both ends of the Vented Cable.
