Important!
Read the following instructions completely - BEFORE installing the ViewRite.
Installation Precautions and Preparation
Failure to observe these precautions could affect the operation of your unit.
1. When locating the tank ports for the ViewRite, make sure that no strong magnetic fields or magnetic materials
(such as railings, protective cages, I-beams, etc.) will be any closer than 6 inches (153 mm) from the ViewRite.
2. Make necessary efforts to ensure that all tank-side modifications and equipment; i.e., the mating flanges, NPT
ports or shut-off valves (if used) will align properly with the connections. Improper alignment could
cause distortion and may damage welds and compromise the integrity of the ViewRite and/or the tank.
3. After any necessary tank modifications are completed, the tank should be cleaned to remove contaminants. This
will ensure that the installation is free of foreign particles; especially those which could be magnetic and which
could impair the performance of the ViewRite.
4. Do not begin the installation of the ViewRite until all necessary tools and materials are obtained. (Such as
mating flange gaskets, bolting hardware, etc. )
5. Gasket material typically supplied with the standard ViewRite unit is either Viton or nitrile rubber, Garlock 3000
style. Higher pressure units are typically supplied with Flexitallic
TM gaskets.
6. All supplied flag assembly clamps are intended to be installed with a torque on the clamp screw not to exceed
5 lb.-inches.
Installation
Caution
Handle the ViewRite with care to avoid damaging the threaded areas, flange surfaces, etc.
For Standard ViewRites (Alloy and Mini)
1. Remove the protective packing materials from your ViewRite.
2. Position the unit horizontally on a level surface.
3. Unpack the float assembly or, with the aid of a wire-cutter or similar device, remove the strapping that secures
the float to the exterior of the ViewRite Unit.
