Positioning

Determine the positions for the control unit and the "VG" and "VF"
tanks (if used).
• The control unit can be installed on either side or in front of the
"VG" primary tank. The distance of the control unit to the primary
tank results from the connection set supplied.

For add-on components, proceed as follows:
1. Install the Reflex Exvoid (2) at the connection of the corresponding
vessel.
2. Remove the protective cap from the degassing valve.
3. Use the compression fitting to install the pressure compensation
elbow (1) for ventilation at the vessels.

Note!
Install the "LIS" pressure pick-up only after finalising the
installation of the primary vessel, see chapter 7.3.3 "Tank
installation" on page 11 .
