- 3 VALVE BYPASS: Close the inlet valve and open

a soft water faucet. Then close the outlet valve and

open the bypass valve.
- SEARS SPECIAL BYPASS: Slide the bypass valve

stem to bypass position. Loosen the 3 hex head

screws (see A in drawing) toward the backside of

the valve to allow pressure water to bleed out.

Catch the water with a rag.

DISASSEMBLY

To remove a part or group of parts, refer to the

valve drawing. A common screwdriver or nut

driver, Phillips screwdriver and pliers are the only

tools needed to completely disassemble.

SERVICING THE VALVE

Inspect all oĆrings, seals and gaskets for wear or

defects.
Inspect the bottom surface of the rotor and disc for

scratches, chips or wear.

NOTE:

If replacement is needed, be sure to use

the current replacement part.

ASSEMBLY

Be sure all parts are in place and in the proper

position. Lubricate ALL oĆrings and seals with FDA

approved silicone grease. To install the rotor seal,

first place the seal into the valve groove, rounded

side down (see crossĆsection). Apply a light

coating of silicone grease to the seal's crossing

ribs. Then, carefully center the wear strip on the

seal, and push it downward onto the seal.
Install the nozzle and venturi seal and drain seal.

Assemble 2 oĆrings and the wave washer onto the

rotor and disc. Then center the rotor and disc, in

the valve body, on the rotor seal.
Lower the cover onto the valve body and rotor

shaft. Then install the cover holding screws.

BEFORE TIGHTENING THE SCREWS, INSTALL

THE VALVE CAM AND GEAR. THEN TURN THE

ROTOR (CLOCKWISE ONLY) TO SERVICE POSIĆ
