Installation Sheet

Push Button Actuator Assembly
1. Leakage occurs at the push button.
A. Damaged or worn seals or lime build-up in the actuator cartridge.
Replace with new HY-32-A cartridge.
2. Flushometer does not flush and a small amount of leakage is visible
on the fixture.
A. Foreign material is lodged in the cartridge. Remove and inspect
cartridge for foreign material. Clean cartridge under running water.
B. Damaged or worn seals or lime build-up in the actuator cartridge.
Replace with new HY-32-A cartridge.
C. Plastic tubing installed incorrectly. Install plastic tubing correctly.
Actuator Cartridge Removal at Push Button
Plastic Push Button
1. Loosen the set screw in the button flange and remove the button, flange
and spring from the actuator body.
2. Unscrew the cartridge from the actuator body.
NOTE: An automatic check valve in the actuator body allows removal of the cartridge
without turning off the water supply.
Metal Push Button
1. Remove the button or actuator assembly from the wall or the fixture.
2. Disassemble the flange or button assembly from the actuator body.
3. Unscrew the cartridge from the actuator body.
NOTE: The metal push button was designed to be vandal resistant and must be
removed from the wall before servicing.
Flushometer Actuator Assembly
1. The Flushometer does not flush or flushes only once and will not
flush 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 the actuator housing and cartridge from the
Flushometer. Clean under running water. If cartridge parts are worn,
deteriorated, or limed up and the problem persists after cleaning,
replace with new H-83-A cartridge (item 29).
B. Plastic tubing installed incorrectly. Install plastic tubing correctly.
Actuator Removal from the Flushometer
1. Turn off water at the control stop (item 11).
2. Unscrew the housing coupling nut (item 26) from the Flushometer.
3. Remove the valve actuator housing (item 22) from the Flushometer. The
tubing (item 25) can be left intact.
4. Remove the actuator cartridge assembly (item 29) from the Flushometer
body. Care should be taken upon removal so that the actuator does not
abruptly separate due to spring compression within. If the actuator
cartridge is lodged in the body cavity, grip the exposed portion gently with
a pair of channel-lock pliers and rotate back and forth to loosen the O-ring
seal.
5. Separate the actuator housing to reveal the spring and plunger. Inspect for
wear and, if necessary, replace with new actuator cartridge assembly (item
29).
Flushometer Service
1. The Flushometer does not function.
A. The control stop or main water supply valve is closed. Open control
stop or main water supply valve.
2. The volume of water is insufficient to adequately siphon the fixture.
A. The control stop is not open wide enough. Open control stop for
desired delivery of water.
B. Urinal inside parts installed incorrectly in a closet Flushometer. Replace
with correct closet inside parts kit (see item 7).
C. Inadequate volume or pressure at the water supply valve. If no gauges
are available to properly measure the supply pressure or the volume of
water at the Flushometer, completely remove the entire diaphragm
assembly (item 7). Open the control stop and let water pass through
the empty Flushometer body. Make sure that the water supply is
adequate to siphon the fixture. If this does not provide a satisfactory
siphon, steps should be taken to increase the water supply pressure
and/or volume.
3. The Flushometer closes off immediately.
A. The diaphragm is ruptured or damaged. Install new inside parts kit (see
item 7).
B. The bypass hole is enlarged from corrosion or damage. Install new
inside parts kit (see item 7).
4. The length of the flush is too short.
A. The diaphragm (item 5) and the guide assembly (item 6A, B, C, D or E)
are not properly tightened. Screw diaphragm and guide assembly
together and tighten by hand (see diagram for item 7).
B. The by-pass hole is enlarged from corrosion or damage. Install new
inside parts kit (see item 7).
C. Urinal inside parts installed incorrectly in a closet Flushometer. Replace
with correct closet inside parts kit (see item 7).
5. The len gth of the flush is too long or continuous.
A. The relief valve of the inside parts assembly (item 3A, B, C or D) is not
seating properly or the by-pass hole is clogged with foreign material or
by a gelatinous film caused by “overtreated” water. Disassemble the
working parts and wash under running water.
NOTE: THE SIZE OF THE DIAPHRAGM BY-PASS ORIFICE IS OF UTMOST IMPORTANCE.
DO NOT ENLARGE OR DAMAGE THIS HOLE. DO NOT USE A PIN OR OTHER
SMALL OBJECT TO REMOVE DIRT FROM THIS ORIFICE.
B. Line pressure has dropped and is no longer sufficient enough to force
the relief valve to seat properly. Close control stop until adequate
pressure has been restored to the line, then reopen control stop.
6. Water splashes out from the fixture.
A. The water supply volume is more than required. Throttle down control
stop to reduce volume.
B. Lime has accumulated on the vortex or spreader hole of the fixture.
Remove lime accumulation.

Troubleshooting Guide
ATTENTION INSTALLERS: With the exception of the control stop inlet, DO NOT USE pipe sealant or plumbing grease on any valve component or coupling! To protect the
chrome or special finish of Sloan Flushometers, DO NOT USE toothed tools to install or service these valves. Use our A-50 Super-Wrench™ or other smooth-jawed wrench
to secure couplings. Regulations for low consumption fixtures (1.6 gpf/6.0 Lpf closets and 1.0 gpf/3.8 Lpf urinals) prohibit use of higher flush volumes. Push Button Actuator

Maintenance Guide
Control Stop Setting
IMPORTANT: 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.
