Sloan 110 Regal Exposed Flushometer - Manual (Page 5)

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.

CARE AND CLEANING
TROUBLESHOOTING GUIDE
I. Flushometer does not function (no flush).
A. Control stop or main valve is closed. Open control stop or main valve.
B. Handle assembly is damaged. Replace handle (B-32-A or B-73-A) or
install handle repair kit (B-50-A).
C. Relief valve is damaged. Replace inside parts kit.
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 inside a closet flushometer. Replace inside urinal
parts with proper closet flushometer parts.
C. Low consumption flushometer installed on a non-low consumption fixture.
Replace A-41-A inside parts kit with A-38-A water saver kit.
D. Water saver kit installed in old, non-water saver bowl. Position refill head
A-170 so that SIDE 1 is in the UP position.
E. Inadequate volume or pressure at supply.
• If no gauges are available to properly measure supply pressure or
volume of water at the flushometer, then remove the relief valve from
the inside parts kit, reassemble the flushometer and open the control
stop. If the fixture siphons, more water volume is required. If a 3.5
gpf inside parts kit is installed in the flushometer, then first flip the
refill 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 flow is still required, try a low pressure
guide kit A-175-A (#0301104). IMPORTANT — LAWS AND
REGULATIONS PROHIBIT THE USE OF HIGHER FLUSHING
VOLUMES THAN LISTED ON FIXTURE OR FLUSHOMETER.
• If fixture does not siphon or if a low consumption fixture is installed,
or if the above steps do not prove satisfactory, steps must be taken to
increase the pressure and/or supply.
3. Flushometer closes off immediately.
A. Damaged diaphragm. Replace inside parts kit to correct problem.
B. Enlarged by-pass orifice from corrosion or damage. Install inside parts kit
to correct problem and update flushometer.
4. Length of flush is too short (short flush).
A. Diaphragm assembly and guide assembly are not hand-tight. Screw the
two assemblies hand-tight.
B. Enlarged by-pass orifice from corrosion or damage. Install NEW Inside
parts kit to correct problem and update flushometer.
C. A-19-AU (Black) urinal relief valve in closet flushometer. Replace relief
valve with A-19-AC (White) closet relief valve.
D. A-41-A low consumption kit installed in non-low consumption fixture.
Replace with proper Inside Parts Kit.
E. Handle assembly is damaged. Replace handle (B-32-A or B-73-A) or
install handle repair kit (B-50-A).
5. Length of flush is too long (long flushing) or fails to close off.
A. Relief valve (A-19-A) is not seating properly or by-pass orifice is clogged
because of foreign material, or by-pass orifice is closed by an invisible
gelatinous film from “over-treated” water. Disassemble the working parts
and wash thoroughly.
NOTE: SIZE OF THE ORIFICE IN THE BY-PASS 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 KIT IF CLEANING DOES NOT
CORRECT PROBLEM.
B. Line pressure has dropped and is not sufficient to force Relief Valve to
seat. Shut off all control stops until pressure has been restored, then
open them again.
C. A-19-AC (White) closet Relief Valve has been used in a 1 or 1½ gpf
Urinal. Replace with A-19-AU (Black) Relief Valve.
D. Inside cover is cracked or damaged. Replace the Inside Cover (A-71).
6. Chattering noise is heard during flush.
A. Inside Cover is damaged. Replace Inside Cover (A-71).
B. A-156-A Segment diaphragm has been installed upside-down. Reposition
the Segment diaphragm properly (see markings on the Diaphragm).
7. Handle Leaks.
A. B-39 Handle Seal is worn or damaged. Install new B-39 Seal.
NOTE: The B-39 Seal will easily slide onto the B-40 Bushing when wet.
B. Handle gasket has been omitted. Install Handle gasket (A-31) or Sloan
handle repair kit (B-50-A).
C. Valve handle bushing is worn. Replace handle repair kit (B-50-A).
