6.
Proceed to step 20 to complete installation.
Using the Optional Insertion Tool
7.
Attach a customer-supplied hydraulic hand pump to insertion valve A ( Figure 3 ).
8.
Slowly open the pipeline isolation valve. Check for leaks and repair as necessary.
9.
Open retraction valve B to vent trapped air ( Figure 3 ).
10.
Close the release valve on the outlet of the customer hydraulic hand pump.
11.
Open insertion valve A ( Figure 3 ).
12.
Slowly stroke the customer hydraulic hand pump to insert the insertion tool shafts into the insertion tool housings. 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.
13.
Using the alignment indicator rod, guide the shaft slowly into the pipeline. The alignment indicator rod should be
parallel to the pipeline.
14.
Continue to stroke the customer hydraulic hand pump until either the desired insertion depth has been reached or the
insertion tool shafts are completely inserted into the insertion tool housings.
15.
As necessary, align the lock collar holes with the lockdown studs on the lubricator body.
16.
Once the lock collar seats on the lockdown studs, return the hex nuts to the lockdown studs and tighten firmly ( Figure
13 ).
DO NOT stop applying pressure to the insertion shaft until the lock collar has been secured to the lockdown studs.
If the lock collar does not align with the lockdown studs, the inFlow™ ACE may be out of alignment. See Section 2.3, Preparing
the Unit for Installation, for instructions on properly aligning the unit.
17.
Once the lock collar is secured to the lubricator body, close all valves, and then close the customer hydraulic hand
pump (
Figure 3 ).
18.
Disconnect the customer hydraulic hand pump from insertion valve A ( Figure 3 ).
19.
Continue to step 20 to complete installation.
