Using an Auxiliary Gas (Optional)
An auxiliary gas supply is OPTIONAL for this unit. However, for products containing liquid, sand, or other abrasive contaminants,
Welker strongly recommends the use of an auxiliary gas (e.g., clean, dry nitrogen gas) to prevent damage to the insertion
cylinder.
13.
With isolation valve A closed, connect a customer-supplied auxiliary gas supply to vent/relief valve B (
).
14.
Regulate the customer-supplied auxiliary gas supply to a pressure equal to the pipeline pressure.
15.
Slowly open the pipeline isolation valve. Check for leaks and repair as necessary.
16.
Open the valve on the customer-supplied auxiliary gas supply.
17.
Slowly open vent/relief valve B (
). The insertion shaft will begin to insert into the pipeline.
Once the insertion shaft begins to insert, do not open the valve any further. The insertion shaft should be inserted slowly and
smoothly. Opening the valve too quickly or too much may cause the insertion shaft to insert into the pipeline too quickly and
may result in damage to the unit.
18.
Using the alignment indicator rod, guide the shaft slowly into the pipeline. The alignment indicator rod should be
parallel to the pipeline.
19.
As necessary, align the lock collar holes with the alignment nuts on the top cap (
).
20.
Once the lock collar seats on the alignment nuts, return the hex bolts to the alignment nuts and tighten firmly (
).
DO NOT stop applying pressure to the insertion shaft until the lock collar has been secured to the alignment nuts.
21.
Once the lock collar is secured to the top cap, close vent/relief valve B, and then close the customer-supplied auxiliary
gas supply (
).
22.
Disconnect the customer-supplied auxiliary gas supply from vent/relief valve B (
23.
Proceed to step 34 to complete installation.
