1.
NORMAL OPERATION POSITION:
The inlet and outlet handles point in the direction of flow
indicated by the engraved arrows on the control valve. Water flows through the control valve for normal
operation of a water softener. During the regeneration cycle this position provides regeneration water to
the unit, while also providing untreated water to the distribution system
(Fig. 1)
.
2.
BYPASS POSITION:
The inlet and outlet handles point to the center of the bypass. The system is
isolated from the water pressure in the plumbing system. Untreated water is supplied to the building
(Fig. 2)
.
3.
DIAGNOSTIC POSITION:
The inlet handle points toward the control valve and the outlet handle
points to the center of bypass valve. Untreated supply water is allowed to flow to the system and to
the building, while not allowing water to exit from the system to the building
(Fig. 3)
. This allows the
service technician to draw brine and perform other tests without the test water going to the building.
NOTE:
The system must be rinsed before returning the bypass valve to the normal position.
4.
SHUT OFF POSITION:
The inlet handle points to the center of the bypass valve and the outlet
handle points away from the control valve. The water is shut off to the building. The water treatment
system will depressurize upon opening a tap in the building. A negative pressure in the building
combined with the softener being in regeneration could cause a siphoning of brine into the building.
If water is available on the outlet side of the softener, it is an indication of water bypassing the
system
(Fig. 4)
(i.e. a plumbing cross-connection somewhere in the building).
