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.

Nozzle assembly service, page 17

Install the nozzle and venturi seal and drain seal. Assemble wave washer bearing, the wave washer, and 2 o-rings onto the rotor top shaft. Then center the rotor 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

position. Tighten the screws using a criss-cross pattern. If a torque wrench is available, torque to 30-40 inch pounds.

Lubricate the gear on the motor, and the valve cam

gear with Molykote grease, or other high quality gear lubricant.

Be sure to orient switch as shown, with lever toward the cam.
