SIPHON VORTEX LOW PROFILE ONE-PIECE TOILETS INTRODUCTION This service instruction will help you understand the opera tion and repair of Kohler low profile onepiece toilets. The following models are included in these instructions: K-3378-EB PILLOW TALK K-3383-EB PALARRE K-3385-EB ROCHELLE K-3397-EB SAN RAPHAEL K-3402-EB RIALTO K-3408-EB CABERNET THEORY OF OPERATION Consider how a low profile, onepiece toilet differs from the closecoupled toilet. All the water in a close coupled toilet is held in a tank that is above the rim of the bowl. Water to the rim and jet is supplied by gravity. On the other hand, a onepiece toilet holds all the tank water below the rim of the bowl as shown in Fig. #1. Fig. #2 After the flush is completed, the diverter valve directs water to the rim for bowl refill, and to the tank for tank refill. Since water which only will be directed to the jet is stored in the tank, sufficient water to the rim must be supplied by the supply valve as shown in Fig. #3. Fig. #1 When the trip lever is actuated, water enters the supply valve and flows to the diverter valve. At this point all line water is diverted to the rim. The tank water is only used to start the water action in the bowl, and to direct water to the upleg of the trapway to start the siphonic action as illus trated in Fig. #2. 106423-0290 Fig. #3 I.P.S.

Refer to the roughingin draw ings Figs. #4 - #9. Slotted screw on newer models Always refer to your local codes and the installation in structions packed with the toilet. KOHLER LOW PROFILE ONEPIECE TOILET FEATURES Seal Screw Onepiece design offers contemporary styling. Elongated bowl offers a large water area for efficient waste removal. Nonoverflow design prevents the bowl from overflowing if the toilet becomes clogged. Rialto, San Raphael, Cabernet, and Pillow Talk toilets flush with 3.5 gallons of water for greater economy. TwistLock flush valves on new Rialto, San Raphael, Cabernet, and Pillow Talk toilets offer ease of replace ment with no tools. Siphon vortex action provides excellent flush and quiet operation. Large water area in bowl aids in effective waste removal. STARTUP AND OPERATION FOR RIALTO, SAN RAPHAEL, CABERNET, AND PILLOW TALK TOILETS For most satisfactory operation of this toilet, 25 to 90 psi working pressure is required at the fixture. A full 1/2" sup ply stop (K-7653) is recommended. A plastic nut is pro vided with the toilet and must be used to make the supply connection to the toilet. 1. Water Level Adjustment: Refer to Fig. #10. Turn on the water supply to the toilet and adjust the water level in the tank to the Water Line mark on flush valve. To raise the water level, turn the tank water level on float valve counterclockwise. To lower the water level, turn the screw clockwise. 2. Bowl Water Level Adjustment: Use the trip chain to lift the flush ball in the tank slightly, to allow water to trickle into the bowl until the water level in the bowl stops ris ing. This is the "seal height" and should be noted for subsequent adjustment. Flush the toilet and observe the water level in the bowl after refill. If the water level is -3- Adjusting the Float Valve Fig. #10 below seal height, turn the seal screw clockwise, reflush the toilet and recheck the water level. Continue adjustment until water stops entering the bowl just as the seal height is reached. If water continues to flow (in bowl) after water level reaches seal height, turn seal screw counterclockwise and reflush toilet. Continue adjustment until water stops entering the bowl just as the seal height is reached. 3. High Water Pressure Timing: Note: If toilet is installed in an area with high water pressure (above 50 psi work ing pressure), the float valve should be timed. To time the float valve hold the float rod and flush the toilet. After the toilet has completed the flush, time the refill from re lease of rod to valve shut-off. For K-3397-EB San Raphael, K-3378-EB Pillow Talk, and K-3408-EB Cabernet. If the time is longer than 34 seconds, no adjustment is required. If time is under 34 seconds, turn timing screw clockwise and recheck timing. Adjust timing screw until time is between 34 and 36 sec onds. After timing the valve, recheck the bowl water level as in step #2, to ensure that seal is maintained. For K-3402-PB Rialto. If the time is longer than 26 sec onds, no adjustment is required. If time is under 26 sec onds, turn timing screw clockwise and recheck timing. Ad just timing screw until time is between 26 and 28 seconds. After timing the valve, recheck the bowl water level as in step #2, to ensure that seal is maintained. HOW TO REPAIR THE RIALTO, SAN RAPHAEL, CABERNET, AND PILLOW TALK FLOAT AND FLUSH VALVE.

The float valve assembly controls the flow of water through the rotor to the rim holes and tank. The adjusting screw Cap Assembly Adjusting Screw Plunger S.A. Float Rod Float Ball Seat O-ring Rubber Gasket Rotor Lift Chain Rim Flush Tube Hush Tube Screw Rotor Arm Lift Wire Trip Chain Plastic Collar Gasket Locknut Flush Ball Flapper Hooks Rubber Seat Gasket Seat Clamp Supply Connection Flush Ball Rochelle/Palarre Tank Fitting Fig. #14 Screws Trip Lever Assembly Mounting Hooks Volume Control Float Rod Rotor Old Style Flush Valve Fig. #13 Rim Flush Tube controls flow at various water pressures. An antisiphon valve prevents backflow. For most satisfactory operation of this toilet, 25 to 80 psi working pressure is required at the fixture. A full 1/2" sup ply stop (K-7653) is recommended. A pressure regula tor is recommend when pressure exceeds 125 psi. The flush valve controls the flow of water from tank to bowl. The flush ball and lift wire control valve operation at the end of the flush. The lift wire provides for the accurate seating of the flush ball. BEFORE YOU BEGIN ADJUSTMENTS: Refer to exploded view illustration (Fig. #14) and Fig. #15. Make sure you understand the following before you refer to the Troubleshooting Chart. -5- Directional Valve Lift Wire Flush Valve Trip Lever Tank Fitting Assembly Fig. #15 WATER LEVEL. The water level must be at the waterline indicated at the back of the tank for proper flushing of bowl. Bend float rod if necessary to obtain the proper water level. The flush valve will not shut off if the water is above the overflow. If any pressure variation occurs in the supply line, adjust the water level when the water pressure is at its highest point. VOLUME CONTROL. If necessary, you can adjust the flow of water with adjusting screw. Decrease the flow by turning the screw downward or increase the flow by turn ing the screw upward. The screw must be locked after adjustment with the locknut. TRIP LEVER ASSEMBLY. When the trip lever arm is at rest, rotor arm should not contact bottom of lift chain. If necessary, bend trip lever arm downward to maintain clearance. ROTOR ASSEMBLY. The rotor arm should rest on the bottom of lift wire loop. 2.
