Using Hydraulic Fluid (Optional)
If using hydraulic fluid to insert and retract the insertion shaft, the customer must provide a way to drain the hydraulic fluid
from the insertion cylinder.
Welker recommends adding a pressure gauge to the hydraulic supply so that the maximum allowable operating pressure of the
unit is not exceeded.
Hydraulic fluid provides the smoothest insertion and retraction.
3.
With isolation valve A closed, install a customer-supplied hydraulic supply (e.g., a hydraulic hand pump) to vent/relief
valve B (
4.
Slowly open the pipeline isolation valve. Check for leaks and repair as necessary.
5.
Open the valve on the customer-supplied hydraulic supply.
6.
Slowly open vent/relief valve B, and then slowly apply hydraulic fluid to the unit. 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.
7.
Using the alignment indicator rod, guide the shaft slowly into the pipeline. The alignment indicator rod should be
parallel to the pipeline.
8.
As necessary, align the lock collar holes with the alignment nuts on the top cap (
).
9.
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.
10.
Once the lock collar is secured to the top cap, close vent/relief valve B, and then close the customer-supplied hydraulic
supply (
11.
Disconnect the customer-supplied hydraulic supply from vent/relief valve B (
12.
Proceed to step 34 to complete installation.
