ITEM
DESCRIPTION
90246-94
1 Bypass
Makes the connection between the plumbing and the Main Valve Body. Also,
Housing
contains the “Hard Water” Blending Valve and Bypass Piston. The
recommended seal for the 1 ¼" male inlet-outlet threads is the nylon Hook-up
Nut (Part No. 90251), O-ring (Part No. 90837), and Copper Adapter (Part No.
90254). Make sure the O-ring is between the housing and the Copper Adapter.
The O-ring seal areas at the main Valve Body inlet and outlet must be smooth
and free of defects and debris, and lubricated with silicone grease before
assembling. When attaching to the Main Valve Body, put O-rings on the male
bosses on the Valve Body and push the Bypass into place. A “snap” can be
heard when the Bypass slides into place. When released, the Bypass should
stay in place. If not, the O-rings may be “pinched”. If the O-rings are pinched,
replace with new ones. The Bypass comes pre-assembled with the Sensor
housing and turbine axle. These are not field serviceable and if damaged, must
be replaced with a new assembly. The Bypass Piston bore is to be smooth and
at the recessed areas have a smooth transition (no sharp corners) to the seat
areas.

1 Bypass End
Seals the left Piston opening on the Bypass Housing (Part Number 90246-94).
Cap-Left
The opening is sealed with an O-ring used as an axial or “face” seal. The O-ring
sits in a groove in the End Cap. This groove must be free of defects such as pits
or scratches and also free of debris. When assembling the End Cap to the
Housing, care should be taken to make sure that the O-ring stays in the groove
in the End Cap. If misaligned, the O-ring can become pinched and leak. Also, on
the End Cap is the Piston Axle, a 1/4" square shaft that acts as a guide/slide and
anti-turning mechanism for the Bypass Piston.
90263
1 Bypass End
Seals the right Piston opening on the Bypass Housing (Part Number 90246-94).
Cap-Right
The opening is sealed with an O-ring used as an axial or “face” seal. The O-ring
sits in a groove in the End Cap. This groove must be free of defects such as pits
or scratches and also free of debris. When assembling the End Cap to the
Housing, care should be taken to make sure that the O-ring stays in the groove
in the End Cap. If misaligned, the O-ring can become pinched and leak. Also, on
the End Cap is the guide/bushing for the Bypass Piston Drive Shaft. There is an
O-ring seal at the opening for the Drive Shaft. This seal must be free of defects
such as pits or scratches and also free of debris.
90218
1 Bypass Drive
The Bypass Drive Shaft has an acme thread which is used to move the Piston
Shaft
from the “bypass” to “service” position. When operating the Bypass, to achieve
either “service” or “bypass,” it is only necessary to turn the Handle (Part Number
90221) until the Piston (Part Number 90616) stops. Additional pressure (torque)
will not improve the seal. As a matter-of-fact, once the Piston reaches the stop
at either position, it can be backed off up to one-half turn of the handle and still
achieve a seal.
90616
1 Bypass Piston
The white Teflon Hydro-slide O-ring covers should be free of defects such as
Assembly
indentations and cuts. The Piston should move freely into and out of the Bypass
Housing without damaging the Hydro-slides. If the Hydro-slides catch, tear, or
crimp, the Housing should be replaced. NOTE: Some compression will occur
when the Hydro-slides pass through the seal areas.
90221
1 Bypass Knob
90222
1 Blending Valve
Permits the addition of “hard water” into the soft water outlet. It is closed when
pointing toward the Main Valve Body, and open when pointing toward the inlet
side.
90252
1 Blending Valve
Held in place by the three 1/2" screws. Should be in the proper orientation.
Cap
90226
1 Test Port Valve
Used to draw water samples for testing of treated water. NOTE: The Bypass
must be in the “service” position to get an accurate sample. There are two types
of seals on the Test Port. One seal is an O-ring which seals off the threaded
area when the Valve is opened. The other seal is a compression seal between
the Test Port Valve material and the Right End Cap material. If this seal is
“overtightened,” it can damage the sealing area on the End Cap causing a
permanent leak.
