5. Remove the plugs from the pipe fittings on the DGA monitor and store them for possible
later use. Check that the fittings are clean.
6. Connect both oil lines to the fittings on the DGA monitor. Use the supplied Swagelokâ
adapters (delivered in a separate bag). See Installing oil lines (page 32), step 9 and
manufacturer's instructions for more information on tightening the fittings.
7. Install pipe supports for the flexible hose. Do not leave the flexible hose on the ground
where it can be stepped over.
8. Ground the flexible tubing and the support materials according to local regulations.
To verify that the oil connections are tight, check for leaks during commissioning
when the DGA monitor is pumping oil. Ideally, check the connections again after
the DGA monitor has been running for some time (for example, the next day).
