2.3 Start-Up Procedures
1.
Ensure that all valves on the GSS-4PM are closed.
2.
Pressurize the pipeline.
3.
As necessary, adjust the inline relief. If the inline relief does not need to be adjusted, proceed to step 22.
If a Welker SC Single Cavity Cylinder will be used for sample collection, continue to step 4.
If a Welker Constant Pressure Cylinder will be used for sample collection, proceed to step 11.
Setting the Inline Relief
The inline relief is designed to allow product to flow in one direction only. Acting as a check valve, the inline relief will ensure
that sample pumped into the sample cylinder cannot flow back to the pipeline even if pipeline pressure drops.
