Bypass Assembly
90246 Bypass Housing: Makes the connection between the plumbing and Main Valve Body. Also, contains the
"Hard Water" Blending Valve and Bypass Piston. The recommended seal for the 1 '/" male inlet-outlet threads
is the plastic Hook-up Nut (90251), 0-ring (90837), and Copper Adapter (90254). Make sure the 0-ring is
between the Housing and Copper Adapter. The 0-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 attach-
ing to the Main Valve Body, put the 0-rings on the male bosses on the Valve Body and push the Bypass into
place; if not, the 0-rings may be "pinched". If the 0-rings are pinched, replace with new ones. The Bypass is
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.
90262 Bypass End Cap - Left: Seals the left Piston opening on the Housing (90246). The opening is sealed
with an 0-ring used as an axial or "face" seal. The 0-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 0-ring stays in the groove in the End Cap. If misaligned, the 0-ring
can become pinched and leak. Also, on the End Cap is the Piston Axle, a '/" square shaft that acts as a guide /
slide and anti-turning mechanism for the Bypass Piston.
90263 Bypass End Cap - Right: Seals the right Piston opening on the Housing (90246). The opening is sealed
with an 0-ring used as an axial or "face" seal. The 0-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 0-ring stays in the groove in the End Cap. If misaligned, the 0-ring
can become pinched and leak. Also, on the End Cap is the guide / bushing for the Bypass Piston Drive Shaft.
There is an 0-ring seal at the opening for the Drive Shaft. This seal area must be free of defects such as pits or
scratches and also free of debris.
90218 Bypass Piston Drive Shaft: The Drive Shaft has an acme thread which is used to move the Piston from
"bypass" to "service" position. When operating the Bypass, to achieve either "service" or "bypass", it is only nec-
essary to turn the Handle (90221) until the Piston (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 Bypass Piston Assembly: The white Teflon Hydro-slide 0-ring covers should be free of defects such as
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 compres-
sion
will
occur when the Hydro-slides pass through the seal areas.
93858 Turbine Sensor Assembly: Picks up the magnetic field from the Turbine and relays it to the Controller.
The three wire assembly connecting the "black wafer" Hall Effect Sensor to the Controller board must not be
severely bent (folded over,) cut, or broken. Care should be taken when putting the Sensor into the Sensor
Housing. The "spring" flap below the Sensor must be gently bent over (on top of) the Sensor, and then the
Sensor slides all the way into the Sensor Housing. The round hole of the Sensor mounting tab is then placed
down over the mounting screw boss. The cap is then put in place and the mounting screw is installed. A slot is
provided in the cap for the wire way to exit. The three-wire socket connector must be properly installed in the
controller. Stops on the connector prevent improper (upside down) assembly. Do not force the connector past
the stops.
90522 Turbine Assembly: The turbine must have a 1/8" diameter Rare Earth magnet pressed into place adja-
cent to the axle opening. When assembled to the axle, the Turbine should spin freely. Do not use any lubri-
cants. If the Turbine should become "jammed", clean and flush the Turbine and Bypass Valve.
90252 Blending Dial Cap: The Cap should be held in place by the three
%2" screws and be in the proper orien-
tation.
90222 Blending Valve: The dial 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.
90226 Test Port Valve: The Test Port Valve is 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 0-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 "over-
tightened", it can damage the sealing area on the End Cap causing a permanent leak.
