PRIOR TO INSTALLATION
Prior to installing the Sloan Flushometer, install the items listed below as
illustrated in the Rough-in Diagrams on Pages 2 and 3.
• Bore a 2” (51 mm) hole in wall for piping, if required.
• Install closet or urinal xture.
• Install 1-1/2” (38 mm) drain line (NOT supplied by Sloan).
• Install water supply line.
• Bore a 1-1/2” (38 mm) hole in wall for Hydraulic Push Button Actuator.
• For Model HY-72-A Push Button Actuator, install an electrical box at the
Push Button Actuator location.
NOTE: MAXIMUM DISTANCE FROM BUTTON TO VALVE IS 20’
(LONGER TUBING REQUIRED)
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 Royal and Regal XL Flushometers are designed to operate with 15
to 80 psi (103 to 552 kPa) of water pressure. THE MINIMUM PRESSURE
REQUIRED TO THE VALVE IS DETERMINED BY THE TYPE OF
FIXTURE SELECTED. Consult xture manufacturer for minimum pressure
requirements.
Most Low Consumption water closets (1.6 gpf/6.0 Lpf) require a minimum
owing pressure of 25 psi (172 kPa).
IMPORTANT: With the exception of Control Stop Inlet, DO NOT use
pipe thread sealant or plumbing grease on valve components or
couplings!
Protect the chrome or special finish of this Flushometer — DO NOT
use toothed tools to install or service the valve. Also, see “Care and
Cleaning” section of this manual.

Sloan Flushometers are engineered for quiet operation. Excessive water ow creates
noise, while too little water ow may not satisfy the needs of the xture. Proper
adjustment is made when the plumbing xture is cleansed after each ush without
splashing water out from the lip AND a quiet ushing cycle is achieved.
Never open Control Stop to where the ow from the valve exceeds the ow capability
of the xture. In the event of a valve failure, the xture must be able to accommodate
a continuous ow from the valve.

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 nishes. 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 uids will discolor or remove chrome plating.
TROUBLESHOOTING
Push Button Actuator Assembly
1. Push Button Leaks.
The actuator cartridge has an accumulation of lime or its seals are damaged or worn.
Replace with a new HY-32-A cartridge.
2. The Flushometer does not ush and a small amount of leakage is visible below the
valve.
A. Foreign material lodged in the cartridge. Remove the cartridge and inspect for
foreign material. Clean under running water.
B. The actuator cartridge has an accumulation of lime or its seals are damaged or
worn. Replace with a new HY-32-A cartridge.
C. Plastic Tubing is installed incorrectly. Install Plastic Tubing correctly
(see Steps 2 and 5).
ACTUATOR CARTRIDGE REMOVAL
Plastic Push Button Actuator Removal:
(1) Loosen the setscrew in the button ange and remove the button, ange, and
spring from the actuator body.
(2) Unscrew the cartridge from the actuator body.
Metal Push Button Actuator Removal:
(1) Remove the button or actuator assembly from the wall or xture.
(2) Disassemble the ange or button assembly from the actuator body.
(3) Unscrew the cartridge from the actuator body.
NOTE: The metal Push Button is designed to be vandal-proof and must be
removed from the wall or xture for service.
Flushometer Actuator Assembly
1. The Flushometer does not ush or ushes only once and will not ush a second
time when the button is pushed.
A. The plunger is lodged in the actuator cartridge or the plunger bypass hole is
clogged. Remove actuator housing and cartridge from the Flushometer. Clean
under running water. If cartridge parts are worn, deteriorated or limed up and
problem persists after cleaning, replace with a new HY-83-A cartridge.
B. Plastic Tubing is installed incorrectly. Install Plastic Tubing correctly
(see Steps 2 and 5).
REMOVAL OF THE ACTUATOR FROM THE FLUSHOMETER:
(1) Turn off water at the Control Stop.
(2) Unscrew the actuator housing coupling nut from the Flushometer.
(3) Remove the actuator housing from the Flushometer. The tubing connections can
be left intact.
(4) Carefully remove the actuator cartridge from the Flushometer body to prevent
the actuator from abrupt separation due to expansion of an internal spring. If
the actuator cartridge is lodged in the Flushometer body cavity, gently grip the
exposed portion of the cartridge with a channel-lock pliers and rotate back and
forth to loosen the O-ring seal.
(5) Carefully separate the actuator housing to reveal the spring and plunger.
Flushometer Service
1. Flushometer does not function (no flush).
A. Control Stop or Main Valve is Closed. Open Control Stop or Main Valve.
B. Relief Valve is worn. Replace Royal Performance Kit (Royal Flushometers) or
Inside Parts Kit (Regal XL Flushometers).
2. Volume of water is not sufficient to siphon fixture.
A. Control Stop is not open wide enough. Adjust Control Stop for desired delivery of
water volume.
B. Urinal Flushometer parts installed in a Closet Flushometer. Replace inside Urinal
Flushometer parts with proper Closet Flushometer parts.
C. Incorrect Dual Filtered Diaphragm Assembly (Royal Flushometers) or Inside
Parts Kit (Regal XL Flushometers) is installed in Flushometer; for instance, Urinal
assembly inside a Closet Flushometer, or Low Consumption assembly inside a
higher consumption xture. Determine the ush volume required by the xture
and replace Royal Performance Kit or Inside Parts Kit. Use valve label and
markings on xture for reference.
D. Water supply volume or pressure is inadequate. If no gauges are available to
properly measure supply pressure or volume of water at the Flushometer, then
remove the Relief Valve from the Dual Filtered Diaphragm Assembly (Royal
Flushometers) or Inside Parts Kit (Regal XL Flushometers), reassemble the
Flushometer and completely open the Control Stop. If the xture siphons, more
water volume is required.
For Royal Flushometers — Install a higher ushing volume Royal
Performance Kit.
For Regal XL Flushometers — If a 3.5 gpf Inside Parts Kit is installed in the
8
Flushometer, then rst ip the Rell Head (under the Diaphragm) to obtain a
4.5 gpf volume. If this volume is still inadequate, remove the Flow Ring from
the Guide to obtain a 6.5 gpf Kit. If additional ow is still required, try a Low
Pressure Guide Kit A-175-A (#0301104).
IMPORTANT — Laws and Regulations requiring Low Consumption
Fixtures (1.6 gpf/6.0 Lpf Water Closets and 1.0 gpf/3.8 Lpf Urinals)
prohibit the use of higher flushing volumes.
If the xture does not siphon or if a Low Consumption ush is required, steps
must be taken to increase the water supply pressure and/or volume. Contact the
xture manufacturer for minimum water supply requirements of the xture.
3. Flushometer closes off immediately.
A. Ruptured or damaged diaphragm. Replace Royal Performance Kit (Royal
Flushometers) or Inside Parts Kit (Regal XL Flushometers).
B. For Regal XL Flushometers — An enlarged bypass orice from corrosion or
damage. Replace Inside Parts Kit.
4. Length of flush is too short (Short Flush).
A. For Regal Flushometers — The Diaphragm Assembly and Guide Assembly are
not hand tight. Screw the two assemblies hand tight.
B. For Regal XL Flushometers — An enlarged bypass orice from corrosion or
damage. Replace Inside Parts Kit.
C. Dual Filtered Diaphragm Assembly (Royal Flushometers) or Inside Parts Kit
(Regal XL Flushometers) is damaged. Replace Royal Performance Kit or Inside
Parts Kit.
D. Incorrect Dual Filtered Diaphragm Assembly (Royal Flushometers) or Inside
Parts Kit (Regal XL Flushometers) is installed in Flushometer; for instance, Urinal
assembly inside a Closet Flushometer, or Low Consumption assembly inside a
higher consumption xture. Determine the ush volume required by the xture
and replace Royal Performance Kit or Inside Parts Kit. Use valve label and
markings on xture for reference.
5. Length of flush is too long (Long Flush) or continuous.
A. For Royal Flushometers — Metering bypass hole in Diaphragm is clogged.
Remove the Dual Filtered Diaphragm Assembly. Remove the Primary and
Secondary Filter Rings from the Diaphragm and wash under running water.
Replace Royal Performance Kit if cleaning does not correct the problem.
B. For Regal XL Flushometers — Relief Valve (A-19-A) is not seating properly or
bypass orice is clogged. Disassemble the working parts and wash thoroughly.
NOTE: SIZE OF THE ORIFICE IN THE BYPASS IS OF UTMOST IMPORTANCE
FOR THE PROPER METERING OF WATER INTO THE UPPER CHAMBER
OF THE FLUSHOMETER. DO NOT ENLARGE OR DAMAGE THIS ORIFICE.
REPLACE INSIDE PARTS KIT IF CLEANING DOES NOT CORRECT PROBLEM.
C. Supply line water pressure has dropped and is not sufcient to close the valve.
