Replacement of Valve Top and Diverter Assembly

If the filter control valve stops functioning properly, the problem can
usually be corrected by replacing the top and diverter assembly as
described below.
1. Switch off pump and open air bleeder to relieve all internal pressure.
2. Set valve handle to "Winterize" position.
3. Remove the six (6) cover screws, washers and nuts.
4. Lift off valve top and diverter assembly.
Note: Valve diverter assembly has the sealing gasket attached
to the diverter. When handling the diverter use caution to
prevent the sealing surface from being damaged during
handling.
5. Clean valve body sealing surface with a soft clean lint free cloth.
Inspect surface for damage such as scratches or nicks. If surface is
damaged, the valve body must be replaced.
6. Carefully lubricate the new valve top replacement O-Ring with a
silicone based lubricant or soapy water. DO NOT use vaseline or a
petroleum based lubricant.
7. Place the new valve top handle in the "Winterize" position. Install the
new valve top and diverter assembly. Be sure the small recess on the
lid and the small bump on valve body are aligned. Install all six (6)
screws with backup washer under the screw head. Install the nuts on
each screw and finger tighten all six (6) screws. The screws should be
tightened progressively by tightening diametrically opposite screws and
following a crisscross pattern. Tighten all six (6) valve top attachment
screws snug. DO NOT OVER TIGHTEN.
Improper tank valve assembly could cause the valve
to separate and cause serious injury or property
damage.
