Before working on the valve, turn off the water

supply and disconnect from electrical power. TO

RELIEVE PRESSURE:

- - 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 back side of the valve

to allow pressure water to bleed out (catch 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 disassembe.

SERVICING THE VALVE

Inspect all o-rings, 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 o-rings and seals with FDA

approved silicone grease. To install the rotor seal,

first place the seal into the valve groove, rounded

side down (see cross-section). 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 o-rings 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 tight-

ening the screws, install the valve cam and gear.

Then, turn the rotor (clockwise only) to service

position. Tighten the screws using a criss-cross

pattern. If a torque wrench is available, torque to

30-40 inch pounds.
