How To Depressurize the Aqualux Prosoft System

To work on the softener, you first need to depressurize it.  This is accomplished by first putting the control valve in the bypass position, and then forcing the system into a regeneration cycle to open the drain port.

Bypass Position

The bypass valve is the set of two on/off valves that sits behind the control valve. In the normal 'service' position, the handles are parallel to each other.  Or stated another way, the handles point in the same direction as the incoming and outgoing water. To put the softener in bypass mode, turn both handles so they are pointing towards one another:

Depressurizing the System

Now that the bypass is closed, to depressurize the system we simply initiate a regeneration of the softener. This is done by pressing and holding the Next Cycle button until the valve mechanism begins to move:

When you see the timer begin to count down, you know that the valve port is open and the system has been depressurized. Because the bypass valve is closed no water will flow to drain. Press the Next Cycle button once to advance to the next stage of the regeneration. When the countdown on the next stage begins press the Next Cycle button again to advance to the next stage. Continue this process until the system exits the regeneration process (BF will be the last cycle).

The system is now fully de-pressurized and ready to be worked on.
