To reduce the risk associated with ingestion of contaminants due to use with water that is microbiologically unsafe or

of unknown quality:

• Do not use with water that is microbiologically unsafe or of unknown quality without adequate disinfection before or after the system.

To reduce the risk associated with a hazardous voltage due to installation on a system that requires use of the

cold water system as a safety ground:

• If the home electrical system requires use of the cold water system as an electrical safety ground, a jumper must be used to

ensure the ground connection across the softener piping — refer installation to qualiﬁ ed personnel.

To reduce the risk associated with back strain due to the heavy weight of the various system components:

• Follow safe lifting procedures.

To reduce the risk associated with hazardous voltage due to damage of the wall mounted power supply:

• Do not use the water treatment unit if the wall mounted power supply is damaged, contact qualiﬁ ed service

personnel for repair.
