WARNING
To reduce the risk associated with choking:
• Do not allow children under 3 years of age to have access to small parts during the installation of this product.
To reduce the risk associated with ingestion of contaminants:
• 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 of physical injury:
• Shut off inlet water supply and depressurize system as shown in manual prior to service.
To reduce the risk associated with a hazardous voltage:
• If the home electrical system requires use of the cold water system as an electrical safety ground, a jumper must be used to ensure
a sufficient ground connection across the water softener installation piping — refer installation to qualified personnel.
• Do not use the system if the power cord is damaged — contact qualified service personnel for repair.
To reduce the risk associated with back strain due to the heavy weight of the various system components:
• Follow safe lifting procedures.
CAUTION
To reduce the risk associated skin, eye, and respiratory tract irritation from gravel and filter media during installation:
• Gravel and several types of filter media may be used in this product, depending upon the application. During installation, dust may
cause irritation to skin, eyes, and respiratory tract.
• Utilize a NIOSH-approved dust filter mask, protective gloves, and appropriate eye protection when handling and pouring gravel
and filter media.
CAUTION
To reduce the risk associated with property damage due to water leakage:
• Read and follow Use instructions before installation and use of this water treatment system.
• Installation and use MUST comply with existing state or local plumbing codes.
• Protect from freezing, relieve pressure and drain system when temperatures are expected to drop below 4°C.
• Do not install on hot water supply lines. The maximum operating water temperature of this water softener is 43°C.
• Do not install if water pressure exceeds 125 psi. If your water pressure exceeds 552 kPa, you must install a pressure limiting valve.
Contact a plumbing professional if you are uncertain how to check your water pressure.
• Do not install where water hammer conditions may occur. If water hammer conditions exist you must install a water hammer
arrester. Contact a plumbing professional if you are uncertain how to check for this condition.
• Where a backflow prevention device is installed on a water system, a device for controlling pressure due to thermal expansion
must be installed.
• Do not use a torch or other high temperature sources near system.
• On plastic fittings, never use pipe sealant or pipe dope. Use PTFE thread tape only, pipe dope properties may deteriorate plastic.
• Take care when using pliers or pipe wrenches to tighten plastic fittings, as damage may occur if over tightening occurs.
• Do not install in direct sunlight or outdoors.
• Install system in such a position as to prevent it from being struck by other items used in the area of installation.
• Ensure all tubing and fittings are secure and free of leaks.
• SHUT OFF FUEL OR ELECTRIC POWER SUPPLY TO WATER HEATER after water is shut off.
• Do not install system where water lines could be subjected to vacuum conditions without appropriate measures for vacuum
prevention.
• Do not apply heat to any fitting connected to bypass or control valve as damage may result to internal parts or connecting
adapters.
• Install on a flat/level surface. It is also advisable to sweep the floor to eliminate objects that could pierce the brine tank.
To reduce the risk associated with property damage due to plugged water lines:
• Pay particular attention to correct orientation of control valve. Water flow 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.
IMPORTANT NOTES
• Failure to follow instructions will void warranty.
Professional Installation Required:
Installation requires shutting water off to home, cutting home water supply pipe and connecting
