3.2.2 Safety precautions using safety engineered swivel hoist
rings
Read and follow the Safety Precautions listed below:
1. Meters must only be lifted by personnel properly trained in the safe practices of rigging
and lifting.
2. Remove the plug bolts installed in the tapped holes on the top of the flanges. Do not
discard the bolts as they must be reinstalled once the lifting operation is complete to
prevent corrosion of the tapped holes.
3. Make sure the tapped holes on the meter are clean and free of debris before installing
the hoist rings.
4. Use only the Safety Engineered Swivel Hoist Rings that are rated for lifting the meter. Do
not use any other type of hoist rings with the same screw size or heavy duty hoist rings.
The meter tapping and counter bore size are suitable only for the hoist rings specified
by Daniel.
5. When installing a hoist ring, make sure the base surface of the hoist ring fully contacts
the machined flat surface of the tapped hole. If the two surfaces do not come in contact
then the hoist ring will not hold its full rated load. Torque the hoist ring attachment
bolts to the limit indicated on the hoist rings.
