Flag Installation
General Notes
Under normal circumstances, it should not be necessary to reposition the flag assembly on your ViewRite. However, if
you find it desirable or necessary to reposition the flag assembly, we strongly recommend that you first mark the dis-
tance from the top of the weldment to the top of the flag assembly. Before securing the flag assembly in a new radial
position, ensure that the distance from the top of the flag assembly to the top of the weldment is the same as the previ-
ously noted dimension. Making a temporary or permanent mark on the weldment can ease the process.
Maintenance
The only maintenance typically required is to ensure that the internal walls of the weldment and the float are free of
foreign matter. This may be accomplished by removing the float assembly from the unit and wiping both the float and
the inside wall of the float chamber or weldment. Any maintenance interval is to be established by the user of the
ViewRite and would depend upon the characteristics of the application. Maintenance could coincide with tank cleaning
or flushing.
Float Installation
Mini ViewRite Float:
To accomplish the removal and subsequent reinstallation of the float assembly, follow the appropriate instructions pro-
vided on page 5 for the ViewRite type and mounting configuration you have selected.

To set magnet position hold the float vertical. A paper clip will attach to the magnet to show its position. Adjust the
magnet position by gently tapping the end of the float.
