in the treated water position, cycling the power will cause
the socket to rotate to that position.
Engage the control by pressing on the release tab and
pushing the camshaft into the control (Figure 10). Do not
force the camshaft. If the camshaft does not slide freely
into the control, check the alignment of the camshaft to
the controller. Ensure it is in the proper position (Figure 7).
The Logix controller moves to the treated water (home)
position when first power is applied.

To disassemble the control from the valve, reverse the
assembling procedure.
Inlet, Outlet and Drain Connections
The inlet, outlet, and drain connections are designed to
accept a GE Water Technologies supplied CPVC or brass
adapter (Figure 11). The adapters provide a convenient
union for the three connection ports on the valve. In
addition, they incorporate a positive O-ring face seal for
ease of installation and leak free operation. DO NOT
OVERTIGHTEN THE ADAPTERS. As a general guideline,
hand tightening the nut onto the valve is adequate. If
additional tightening is required, never exceed a quarter
turn beyond the hand tight position.
The outlet of the 2-inch Magnum IT has an integrated
turbine. The turbine measures the flow of water through
the outlet. This information is used by the controller to
determine the best time to recycle.

No Hardwater Bypass Feature
The Magnum control valve may be configured for "Hard
Water Bypass" or "No Hard Water Bypass". With Hard
Water Bypass, unsoftened or unfiltered water is allowed to
bypass the Magnum control valve during regeneration or
backwash. With No Hard Water Bypass, a valve cartridge
ensures that no unsoftened or unfiltered water bypasses
the valve during regeneration or backwash.
It is easy to observe which option is installed in the valve.
Note that the Hard Water Bypass End Cap has much
longer standoffs than the No Hard Water Bypass
cartridge. The No Hard Water Bypass assembly looks
identical to the other three valve cartridges on the valve
and has a label identifying the cartridge assembly (Figure
12).
