Assemble Inlet and Outlet Plumbing
Measure, cut, and loosely assemble pipe and fittings from the main water pipe to the inlet and outlet
ports of the water softener valve. Be sure to keep fittings fully together, and pipes squared and straight.
Be sure hard water supply pipe goes to the water softener valve inlet side.
NOTE: Inlet and outlet arc marked on the water softener valve. Trace the water flow direction
to be sure hard water is to inlet.
IMPORTANT: Be sure to fit, align and support all plumbing to prevent putting stress on the water
softener valve inlet and outlet. Undue stress from misaligned or unsupported
plumbing may cause damage to the valve.
Connect Inlet and Outlet Plumbing
Complete the inlet and outlet plumbing for the type of pipe as shown below.
^WARNING
Electrical Shock Hazard
Use metal fittings with metal pipe.
Do not use plastic fittings to connect to metal
house pipes.
Failure to follow these instructions can result in
death or electrical shock.
Soldered copper
1. Thoroughly clean and apply solder flux to all joints.
2. Make all solder connections.
NOTE: Do not solder with installation tubes attached to single valve bypass. Soldering heat
will damage the valve.
IMPORTANT: When installing the copper tubes and ground clamp assembly to the single valve
bypass, the ground clamp must be secured in place. If necessary tighten the screw.
