FACTS TO REMEMBER WHILE PLANNING THE INSTALLATION: 

 WARNING

To reduce the risk associated with hazardous voltage:

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

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

CAUTION

To reduce the risk associated with property damage due to water leakage:

• 

Installation must comply

 with existing state or local plumbing codes.

• 

Do not

 install if water pressure exceeds 100 psi (689 kPa). If the system water pressure exceeds 100 psi, the installation 

must

 

use a pressure limiting valve. Contact a licensed plumbing professional if you are uncertain how to check your water pressure.

  Do not install system where water lines could be subjected to vacuum conditions without appropriate measures for vacuum 

prevention.

• 

Do not

 use torches or other heat sources near plastic plumbing, as damage may occur.

  Take care when using pliers or pipe wrenches to tighten plastic fi ttings, as damage may occur.

  On plastic fi ttings, use thread sealing tape only. Never use pipe sealant or pipe dope on plastic fi ttings, as damage may occur.

To reduce the risk associated with property damage due to plugged water lines:

  Pay particular attention to correct orientation of control valve. Water fl ow should match arrow on control valve. The Inlet and 

Outlet of other water treatment equipment products will vary depending on the control valve brand used.

Remember that the fi lter 

INLET

 is attached to the pipe that supplies water (i.e. runs to the pump) and 

OUTLET

 is the line that runs 

toward the water heater or other water treatment equipment device.
Before commencing the installation, it is advisable to study the existing piping system and to determine the size, number and type of 
fi ttings required. Typical system schematics shown in Figure 1 will be of assistance.
