Sloan 140 Royal / Regal Standard Concealed Flushometer - Manual (Page 5)

5
SLOAN FLUSHOMETERS ARE ENGINEERED FOR QUIET
OPERATION. EXCESSIVE WATER FLOW CREATES NOISE,
WHILE TOO LITTLE WATER FLOW MAY NOT SATISFY THE
NEEDS OF THE FIXTURE. PROPER ADJUSTMENT IS MADE
WHEN THE PLUMBING FIXTURE IS CLEANSED AFTER
EACH FLUSH WITHOUT SPLASHING WATER OUT FROM
THE LIP AND A QUIET FLUSHING CYCLE IS ACHIEVED.
NEVER OPEN CONTROL STOP TO WHERE THE FLOW
FROM THE VALVE EXCEEDS THE FLOW CAPABILITY
OF THE FIXTURE. IN THE EVENT OF A VALVE FAILURE,
THE FIXTURE MUST BE ABLE TO ACCOMMODATE A
CONTINUOUS FLOW FROM THE VALVE.
!!! IMPORTANT !!!
Shut off Control Stop by turning handle
CLOCKWISE. Then remove
Flushometer Cover.
A
Lift out the inside Parts Assembly as
a complete unit. Reinstall Flushometer
Cover and tighten with wrench. Open
Control Stop. Turn on water supply to
flush line of any debris or sediment.
B
C Shut off Control Stop and remove
Flushometer Cover. Reinstall Inside Parts
Assembly and Flushometer Cover. Tighten
Cover with wrench. Open Control Stop and
activate Flushometer Valve.
Adjust Control Stop to meet flow
rate required for proper cleansing
of fixture. Open Control Stop
COUNTERCLOCKWISE ONE
FULL turn from closed position. Activate
Flushometer. Adjust Control Stop after
each flush until the rate of flow delivered
properly cleanses the fixture.

5 - FLUSH OUT SUPPLY LINE AND ADJUST CONTROL STOP
1. Flushometer does not function (no flush).
A. Control Stop or Main Valve is Closed. Open Control Stop or Main Valve.
B. Handle or Push Button Assembly is worn. Install Sloan Handle Repair Kit
(C-70-A) or replace handle or push button.
C. Relief Valve is worn. Replace Royal Performance Kit (Royal) or Inside Parts Kit
(Regal).
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 Flushometers) is installed in flushometer; for instance, Urinal assembly
inside a Closet flushometer, or Low Consumption assembly inside a higher
consumption fixture. Determine the flush volume required by the fixture and
replace Royal Performance Kit or Inside Parts Kit. Use valve label and markings on
fixture 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) or
Inside Parts Kit (Regal), reassemble the flushometer and completely open the
Control Stop. If the fixture siphons, more water volume is required.
IMPORTANT — LAWS AND REGULATIONS PROHIBIT THE
USE OF HIGHER FLUSHING VOLUMES THAN LISTED ON
FIXTURE OR FLUSHOMETER.
If the fixture does not siphon or if a Low Consumption flush is required, 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.
3. Flushometer closes off immediately.
A. Ruptured or damaged diaphragm. Replace Royal Performance Kit (Royal) or Inside
Parts Kit (Regal).
B. For Regal Flushometers — An enlarged bypass orifice 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 Flushometers — An enlarged bypass orifice from corrosion or
damage. Replace Inside Parts Kit.
C. Dual Filtered Diaphragm Assembly (Royal) or Inside Parts Kit (Regal) is damaged.
Replace Royal Performance Kit or Inside Parts Kit.
D. Incorrect Dual Filtered Diaphragm Assembly (Royal) or Inside Parts Kit (Regal) is
installed in Flushometer; for instance, Urinal assembly inside a Closet Flushometer,
or Low Consumption assembly inside a higher consumption fixture. Determine the
flush volume required by the fixture and replace Royal Performance Kit or Inside
Parts Kit. Use valve label and markings on fixture for reference.
E. Handle or Push Button Assembly is worn. Install Sloan Handle Repair Kit
(C-70-A) or replace handle or push button.
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 Flushometers — Relief Valve (A-19-A) is not seating properly or
bypass orifice 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 sufficient to close the valve.
Close Control Stop until pressure is restored.
D. Dual Filtered Diaphragm Assembly (Royal) or Inside Parts Kit (Regal) is damaged.
Replace Royal Performance Kit or Inside Parts Kit.
E. Incorrect Dual Filtered Diaphragm Assembly (Royal) or Inside Parts Kit (Regal) is
installed in Flushometer; for instance, Urinal assembly inside a Closet flushometer,
or Low Consumption assembly inside a higher consumption fixture. Determine the
flush volume required by the fixture and replace Royal Performance Kit or Inside
Parts Kit. Use valve label and markings on fixture for reference.
F. White Closet Relief Valve has been used in a Urinal flushometer. Replace Closet
Relief Valve (A-19-AC) with Black Urinal Relief Valve (A-19-AU).
G. Inside Cover is cracked or damaged. Replace the Inside Cover (A-71).
H. Conditions in the piping system may contribute to the noise. A degree of high
pressure in the piping may be relieved by adjustments to Control Stop. Other
noises created by loose pipes, lack of air chambers, inadequate pipe sizes, etc.,
are problems that must be discussed with the building engineer.
6. Chattering noise is heard during flush.
A. Inside Cover is damaged. Replace Inside Cover (A-71).
B. For Regal Flushometers — A-156-A Segment Diaphragm has been
installed upside-down. Reposition the Segment Diaphragm properly (see markings
on the Diaphragm).
7. Leaking at Handle or Push Button Assembly.
A. The B-39 Seal is worn or deteriorated. Install new B-39 Seal.
NOTE: The B-39 Seal will easily slide onto the B-40 Bushing if
it is wet.
B. Handle gasket has been omitted. Install A-31 Handle Gasket or Sloan Handle
Repair Kit (C-70-A).
C. Valve Handle Bushing is worn. Install Sloan Handle Repair Kit (C-70-A).
