To use the Vented Cable Blowout Fitting:
Always follow Personal Protection Protocol when working with a compressed gas.
- Remove the storage caps from both ends of the Vented Cable (remember to save the caps). Or if deployed, remove the logger and Wellhead.
- 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.
Do not exceed 50 psi of pressure when using the Vented Cable Blowout Fitting.
