. 3. Installation
3.1 Comem eOLI
Insert the arm with float through the machined
hole on the conservator Place the o-ring on the
slot behind the gauge
(Fig.1/B) . Align the flange (Fig.1/C - stud length:
20±1 mm) with the threaded pins or holes
(Fig.1/A) (depending on the conservator flange
type). The gauge has to be assembled on the
flange using four screws M4x12 (Fig.1/D). The oil
level indicator flange has to be assembled using
the items showed in the table 1.

3.1 Comem eOLI22
Insert the arm with float through the machined
hole on the conservator. Place the o-ring in the
slot behind the flange (Fig.1/C). Insert the flange
on the threaded pins (Fig.1/A) of the conservator
flange and fix it with the items showed in the
table 2 (Fig.1/B). Fix the gauge on the flange
using 4 screws M4x12 (Fig.1/D).
3.3 Comem eViewer
Arrange the transformer with a dedicated place
following the scheme in the figure 3. The
connection can be done in two alternative way:
• threaded pin and nut M6
• screws M6
