and off the ground. Dirty parts may contaminate the transformer oil or cause
connections to leak.
If the DGA monitor is mounted using the wall mounting set, the power supply unit
will be attached by a mounting cradle. Make sure you are not routing the oil lines
so that they will obstruct the power supply unit attachment. See
Supply Unit (page
Wear protective eyewear and gloves.
If you are unsure which valves on the transformer to use for oil intake and return, see
Recommended Locations of Oil Connections (page
1. Inspect the selected oil valves on the transformer. If there are any flow direction control
valves previously installed, remove them. The DGA monitor needs to pump oil in both
directions during initialization, and this will not work if there are flow direction controllers
in the oil lines.
2. Clean the oil valves on the transformer from the outside and the inside. Use the
degreasing cleaning spray.
3. Install the adapters to the inlet and outlet valves on the transformer to match them to the
size of the oil pipe material.
4. Measure the distance from the oil valves to the DGA monitor, and plan the length and
shape of the oil pipe sections. Minimize the amount of joints.
5. Cut and bend the oil pipe to appropriate sections for building the oil lines.
6. Remove any sharp edges from the cut surfaces.
7. Clean any metal shavings from inside the pipes using pressurized air.
8. Build the oil lines between the valves and the oil connections on the DGA monitor marked
Oil In and Oil Out.
CAUTION!
below oil level. There must be no risk of drawing gas into the oil lines even

9. Remove the plugs from the pipe fittings on the DGA monitor and store them for possible
later use. Check that the fittings are clean.
