Using the Optional Insertion Tool
10.
Attach the customer hydraulic hand pump to insertion valve A ( Figure 3 ).
11.
Ensure that the hydraulic hand pump release valve on the customer hydraulic hand pump is closed.
12.
Open insertion valve A ( Figure 3 ).
13.
Stroke the customer hydraulic hand pump to ensure that there is positive hydraulic pressure in the insertion tool
housings.
14.
Loosen the hex nuts securing the lock collar to the lubricator body ( Figure 13 ). If the insertion tool shafts move, tighten
the hex nuts, and then stroke the customer hydraulic hand pump a few more times to increase pressure in the insertion
tool housings.
Failure to ensure that adequate pressure is applied to the insertion tool prior to retraction could result in unexpected retraction
of the insertion shaft at great speed, which could damage the unit or injure the operator.
15.
Once the hex nuts securing the lock collar to the lubricator body are loose and the insertion tool shafts are not moving,
remove the hex nuts completely.
16.
Close insertion valve A, and then disconnect the customer hydraulic hand pump ( Figure 3 ).
17.
Connect the hydraulic fluid return line from the customer hydraulic hand pump to insertion valve A, and then open
insertion valve A (
Figure 3 ).
18.
Slowly open the hydraulic hand pump release valve to allow hydraulic fluid to flow back into the customer hydraulic
hand pump reservoir through insertion valve A. This will relieve pressure from the insertion tool housings, allowing the
insertion shaft to begin retracting from the pipeline. If pipeline pressure is not sufficient to push the insertion shaft out
of the line, the insertion shaft may be retracted manually or by connecting the customer hydraulic hand pump to
retraction valve B and applying hydraulic pressure to the insertion tool housings.
Once the insertion shaft begins to retract, do not open the valve any further. The insertion shaft should be retracted slowly and
smoothly. Opening the valve too quickly or too much may cause the insertion shaft to retract from the pipeline too quickly and
may result in damage to the unit.
19.
As necessary, open retraction valve B to open trapped air to atmosphere to prevent vapor lock ( Figure 3 ).
20.
Once the insertion tool shafts have traveled through the insertion tool housings and the insertion shaft is fully retracted
from the pipeline, close all valves, and then close the pipeline isolation valve to isolate the unit from pressure (
Figure 3 ).
21.
Disconnect the customer hydraulic hand pump from insertion valve A ( Figure 3 ).
22.
Continue to step 23 to complete retraction.
Completing Retraction
23.
Loosen the cap screws on the sides of the lock collar, and then slide the lock collar down onto the lockdown studs on
the lubricator body.
24.
Tighten the hex nuts to secure the lock collar to the lockdown studs on the lubricator body to prevent the insertion shaft
from moving while the unit is being removed from the pipeline.
25.
Slowly open lubricator vent (drain) valve C to bleed any pressure or liquids trapped in the lubricator body ( Figure 1 or
Figure 3 ).
26.
If complete removal of the inFlow™ ACE from the pipeline is desired, the unit is now ready to be removed from the
pipeline isolation valve for maintenance or to be relocated.
27.
If the inFlow™ ACE will remain secured to the pipeline after retraction, ensure that the lock collar has been properly
secured to the lockdown studs on the lubricator body.
