Unlock the gauge rod by operating the black
thumb screw.
Push the gauge rod downwards. You may have to
use a little force to do so. Try NOT to rotate the
gauge rod when inserting.
Stop pushing the gauge rod downwards when
the depth indicator mark is at the brass locking
component.
Lock the gauge rod by operating the black thumb
screw.
Prior to stopper inflation, verify system / pipeline
pressure is displaying on proper gauge (not more
than 7.5 psi).
The MDS Stopper inflation pressure gauge will be
indicating a pressure of -15 psi.
Attach hand pump and with inflation valve open,
inflate the stopper to 2 times system pressure.
Close the inflation valve.
If this does not secure a complete stop off, inflate
stopper until flow is completely stopped off up to a
maximum of 22 psi.
NOTE: If the condition of the interior of the pipe
being stopped is unknown, it is a recommended
practice to inflate the stopper to the maximum
inflation pressure to obtain the best stop off
possible.
Allow the stopper to stabilize inside the pipeline
for at least 10 minutes.
Verify inflation pressure and system pressure
remains stable.
You may now start your work on the pipeline.
NOTE: Continue to monitor gauges on stopping
towers.
