Warning
D0 NOT: 1) Hold the ViewRite in a vertical position or 2) Drop the float assembly into the unit. Avoid this or
any action which could damage or dent the float. Such damage could cause the float to crush under normal
working pressures.
4. Remove the end cap or flange attaching bolts, as indicated in the appropriate drawing. Then remove
the end cap or flange.
5. With the unit still in a horizontal position, insert the float assembly into the weldment, with the “TOP” indication
on the float assembly moving in the same direction as the “UP” arrows that are located on each side of the
externally mounted flag assembly.
6. With the gasket or O-ring properly positioned, reassemble the end cap or flange to the weldment. Tighten the
end cap or flange bolts securely, using the proper recommended torque value as supplied in Figure A, page 4.
7. Slowly raise the top end of the ViewRite, while the bottom end remains on the level surface, permitting the float
to slowly slide to the bottom, avoiding any sudden impact damage to the float assembly.
8. Move the ViewRite to the tank and position the unit with the end marked “TOP” pointing upwards. Install any
necessary mounting gaskets or seals
1 , and align the mating port flanges, NPT’s or connections of the tank with
those of the ViewRite. DO NOT ATTEMPT TO FORCE ALIGNMENT. To do so may damage the welds or
compromise the integrity of the ViewRite. While following standard practices and procedures, tighten the flange
bolts, NPT’s or connections. Recommended torque values are supplied in Figure A, page 4.
9. Before Filling the Tank . . . . Be sure that the installation is free of foreign particles, especially any that are
magnetic. Check that all connections are secure. A hydrostatic pressure test of the complete assembly
is recommended.
NOTE
Dwyers recommends that you include at least one support bracket in your installation for ViewRite units greater than
10 feet (120 inches, 3048 mm) in length. Depending on the specific installation, a load-bearing support at the base
of the ViewRite may be beneficial.
