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.

6.After installation of the hoist rings, always check that the ring rotates and pivots freely in all directions.

7.NEVER attempt to lift the meter using only one hoist ring.
