System Specifications
Figure 2.Specifications
How Your Water Conditioner Works
The principle behind water softening is simple chemistry. A water softener contains resin beads which hold electrically charged
ions. When hard water passes through the softener, calcium and magnesium ions are attracted to the charged resin beads. It's
the resulting removal of calcium and magnesium ions that produces soft water.
This system is controlled with simple, user-friendly electronics displayed on a LCD screen. The main page displays the current time
and the remaining gallons in meter mode or the remaining days in calendar clock mode.

System Initialization
When power is supplied to the control, the screen will display TIME OF DAY AND DEFAULT GALLON SETTING. If the valve is not in
service it will read “CANATURE” while the valve returns to the service position.
Maximum Water Temperature = 110°F (43°C)
Maximum Operating Pressure = 100 PSIG
(689 kPa)
Voltage = 110 volts standard
Pipe Size = 3/4”
At the stated service flow rates, the pressure drop through these
devices will not exceed 15 psig.
Changing salt settings from factory setting may require
changing injector sizes to achieve stated capacities.
The manufacturer reserves the right to make product
improvements which may deviate from the specifications and
descriptions stated herein, without obligation to change
previously manufactured products or to note the change.
