2. The water softener requires a ground that meets the national and local electrical
code requirements. To prevent possible electrical shock to individuals or
extensive damage to equipment, plug the water softener only into a properly
grounded electrical outlet.
The maximum allowable voltage variation should not exceed ±10 percent of the
rated voltage. Operation of the unit outside of this range may cause damage to
the unit or reduction of the performance.
* Usually an electrical permit and services of a licensed electrician are required.
