into the control. The control indicator must be in the
midpoint of the
SERVICE position for the 962M and
962S when engaging the camshaft into the control.

Important:
When 942, 942Man, 952, or 962 controls are installed,
control dials must be in the REGENERATION
COMPLETE position.
When 942F, 942FMan, or 952F controls are installed,
control dials must be in the BACKWASH COMPLETE
position.
When 962M or 962S controls are installed, control dials
must be in the SERVICE position.
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 an GE Osmonics supplied CPVC or brass
adapter (Figure 2.7). 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 will be
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 control 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 will
look identical to the other three valve cartridges on the
valve and will have a label identifying the cartridge
assembly (Figure 2.8).
