Model CX 198-0.25
Model CX 198-0.125
This valve is designed for new construction or where there is easily accessed plumbing
for the fixture and valve. This valve is designed for a minimum 6-1/2 inch (165 mm) wall
space depth. Distance from the center of the valve (inlet or outlet pipe) to the finished
surface of the wall can vary from 3-1/4” – 4-1/4” (83 – 108 mm).
Wall plate opening must be 7" (178 mm) wide x 8-1/8" (206 mm) tall. Mud plate is
provided and must accompany valve for proper installation. Mud plate is removed after
wall is finished.

IMPORTANT:
• INSTALL ALL PLUMBING IN ACCORDANCE WITH APPLICABLE CODES AND REGULATIONS.
• WATER SUPPLY LINES MUST BE SIZED TO PROVIDE AN ADEQUATE VOLUME OF WATER FOR EACH FIXTURE.
• FLUSH ALL WATER LINES PRIOR TO MAKING CONNECTIONS.
Sloan’s flushometers are designed to operate with 20 to 80 psi (138 to 552 kPa) of water pressure. THE MINIMUM PRESSURE REQUIRED TO
THE VALVE IS DETERMINED BY THE TYPE OF FIXTURE SELECTED.
Consult fixture manufacturer for minimum pressure requirements. Most high efficiency water closets require a minimum flowing pressure of 25 psi (172 kPa).
Many building codes and the ASME A112.19.2 fixture standard list maximum static pressure as 80 PSI (552kPa).

Using depth guide provided, adjust depth of Plunger screw until screw
touches depth guide and secure with nut.

TROUBLESHOOTING GUIDE
1. Flushometer does not function (no water/flush).
A. Ensure water supply to valve is turned on.
B. Shut off sleeve is in closed position. Turn counterclockwise to open water flow. NOTE: There is approximately 1/8-turn (45°) of free spinning as
the activation assembly engages the shut-off sleeve between opening and closing the valve.
C. Plunger screw is not adjusted properly. Adjust screw using depth guide. NOTE: Activation button should be held one (1) second for optimal
performance.
2. Volume of water is not sufficient to evacuate the bowl.
A. Shut off sleeve is not open wide enough. Adjust shut off sleeve for desired delivery of water volume.
B. Urinal piston parts installed in a Closet flushometer. Replace piston with proper Closet piston (1.6 gpf/6.0 Lpf or 1.28 gpf/4.8 Lpf)
C. Water supply volume or pressure is inadequate (low). If the fixture does not siphon or evacuate the bowl, steps must be taken to increase the
water supply pressure and/or volume. Contact the fixture manufacturer for minimum water supply requirements of the fixture.
D. Plunger screw is not adjusted properly. Adjust screw using depth guide.NOTE: Activation button should be held one (1) second for optimal performance.
3. Flushometer closes off immediately.
A. Urinal piston parts installed in a Closet flushometer. Replace piston with proper Closet piston (1.6 gpf/6.0 Lpf or 1.28/4.8 Lpf).
B. Piston lip seal may be damaged or worn. Replace with new correct gpf/Lpf piston.
C. Plunger screw not set properly. Adjust screw using depth guide.
4. Length of flush is too short (Short Flush).
A. Incorrect piston is installed in Flushometer; for instance, Urinal assembly inside a Closet Flushometer,
or High Efficiency assembly inside a higher consumption fixture. Determine the flush volume required by the fixture and replace with proper gpf/
Lpf piston. Use valve label and markings on fixture for reference.
B. Piston lip seal may be damaged or worn. Replace with new correct gpf/Lpf piston.
C. Plunger screw is not adjusted properly. Adjust screw using depth guide.
5. Length of flush is too long (Long Flush) or continuous.
A. Metering bypass hole in piston is clogged. Remove the piston from the valve, slide o ring off filter, and wash under clean running water.
Reposition o-ring before reinstalling piston. Replace piston if cleaning does not correct the problem.
B. Supply line water pressure has dropped and is not sufficient to close the valve. Close shut off sleeve until pressure is restored. NOTE: under
some conditions, opening the shut-off sleeve can correct the force imbalance and cause the valve to close.
D. Piston is damaged. Replace with new proper gpf/Lpf piston
E. Incorrect Piston is installed in Flushometer; for instance, Closet assembly inside a Urinal flushometer. Determine the flush volume required by the
fixture and replace piston. Use valve label and markings on fixture for reference.
6. Chattering noise is heard during flush.
A. Reduce flow pressure by turning shut off sleeve clockwise.
B. Air trapped inside the valve and/or supply pipe. Air takes time-both count of flushes and actual duration - to be fully removed.
CARE AND CLEANING
DO NOT use abrasive or chemical cleaners (including chlorine bleach) to clean Flushometers that may dull the luster and attack the chrome or special decorative
finishes. Use ONLY mild soap and water, then wipe dry with clean cloth or towel. While cleaning the bathroom tile, protect the Flushometer from any splattering
of cleaner. Acids and cleaning fluids will discolor or remove chrome plating.
