Note8 93583 Drive End Cap 1Seals the two openings on the main control valve. The largerdiameter 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 mustbe free of defects such as pits or scratches and also free of debris.The smaller diameter seal is accomplished with an O-Ring used asa radial seal. The O-Ring should be placed on the male boss on theend cap. When assembling the end cap to the main control valve,care should be taken to make sure the small O-Ring is aligned withthe opening in the main control valve and that the largeO-Ring stays in the groove in the end cap. If misaligned, the O-Ringscan become pinched and leak.9 54202 Piston Slide 1 The slide should move freely inside the end cap housing.10 90818 Screw 411 93699R-JG Brine ValveHousing Assembly 1Attaches to the drive end cap with two 3/4-inch self-tapping screwsand has one O-Ring seal.
