GENERAL INSTALLATION GUIDELINES
1. The mounting surface for the base plate and top plate must clear of debris and rough spots
and be level within ± 0.5 degrees to minimize side loads and extraneous forces. If the
mounting surfaces are not level, the base plate has four leveling screws that can be
adjusted up or down as necessary to level the module. Because deflections in legs and
supporting structures may cause additional side forces that greatly affect accuracy, check if
level and plumb again when the container is fully loaded. Cross-bracing of legs or other
support structures may need reinforcement to correct this. Deflections of the module's top
or base plate due to loading should not exceed ± 0.5 degrees.
2. Mounting systems use three or four mounts. The load on each mounting assembly should
vary by no more than 20 percent. Add shims where necessary to achieve correct load
distribution.
3. During installation, dummy load cells can be used to prevent overload damage.
NOTE: If the actual load cells are used during the installation, extreme care must
be taken to prevent overload damage. A tank or hopper weighing several tons
can exert huge forces when dropped only a fraction of an inch.
4. All piping or conduit should be horizontal and flexible. If flexible piping is not used, make
sure the distance from the tank to the first pipe support is 20-30 times the pipe diameter. In
smaller, lower-capacity tanks and hoppers, isolating resultant forces becomes extremely
critical. When possible, flexible conduit piping should be used close to the tank instead of
the rigid variety.
5. Load cells should not be installed in the modules until all welding is completed. If possible,
use a dummy load cell when welding to maintain the finished height. If welding is
unavoidable after load cell installation, ground in such a manner as to prevent welding
current from passing through the load cell. Ground the welder as closely as possible to the
point of welding.
