1. CONNECT FLUSHOMETER
A. B. C. D.
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 WATER PRESSURE AS 80 PSI (552 KPA).
!!! IMPORTANT !!!

2. ADJUST CONTROL FLOW
Valve is shipped with the ow adjustment turned off.
A. Ensure activation assembly is turned fully clockwise to make sure water
is off
B. Push plunger screw in center to relieve pressure. Push in activation
assembly until fully seated.
C. Remove orange safety ring by squeezing pins together and pulling out.
D. Attach supplied screws to threaded holes in activation assembly. Pull
out activation assembly. Do not rotate to avoid turning water on!
E. Remove conical spring. Do not discard!
F. Remove piston by pulling it straight out. If unable to grip piston, remove
screw from front of activation assembly and screw into center hole of
piston.
G. Reinstall activation assembly and press until fully seated.
H. Reinstall orange safety ring securely. Safety ring will spin freely in valve
body when properly installed.
I. Using tool, (along with screwdriver or wrench, if needed), turn activation
assembly counter clockwise slowly to open ow of water to ush the lines-
careful not to overow the xture
J. Once lines are ushed clear, turn activation assembly clockwise to shut
water ow off.
K. Push button/plunger in center to relieve pressure
L. Remove orange safety ring by squeezing pins together
M.Pull out activation assembly using supplied screws. Do not rotate to
avoid turning water on!
N. Reinstall piston - insert smaller sized end rst until fully seated
O.Reinstall conical spring, small end rst, into piston.
P. Reinstall activation assembly and press until fully seated
Q. Reinstall orange safety ring securely. Safety ring will spin freely in valve
body when properly installed.
R. Using tool (along with screwdriver or wrench, if needed), turn
activation assembly slowly counterclockwise to open ow of
water
S. Push plunger screw to activate ush and adjust water ow as needed
by rotating activation assembly (clockwise to lessen ow and counter
clock wise to increase ow)
B.
H.
If supply line was ushed and is clean of debris, proceed to step R.
If supply line was not previously ushed, follow steps A-S.A.
C. D.
E.
THE FLUSHOMETER IS 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 PLUMBING
FIXTURE IS CLEANSED AFTER EACH FLUSH WITHOUT
SPLASHING WATER OUT FROM THE LIP AND A QUIET
FLUSHING CYCLE IS ACHIEVED.
!!! IMPORTANT !!!
THE ACTIVATION ASSEMBLY SHOULD NEVER BE OPENED TO
THE POINT 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 !!!
3. INSTALL BUTTON/BRACKET ASSEMBLY
A. Retrieve button/bracket assembly from box
B. Release the snap feature of the button by inserting the provided
5/64” hex key through the hole at the bottom of the face
plate while pressing at the top of the button.
C. Lift up button to 90 degrees until it locks in up position. Remove
face plate and set aside.
D. Mount black wall bracket to valve, centering wall bracket to valve.
Secure wall bracket evenly with three screws provided until bracket
ush with wall.
E. Slide wall plate over button and wall bracket and secure to
black bracket with two screws provided
F. Choose one of three plunger screws and nut provided and thread
into plunger. If Plunger starts rotating, STOP. This means the screw
has reached the bottom of the hole and overnighting the screw will
cause damage to the Plunger. Try the next shorter screw included
with the product to nish adjustment. Using depth guide provided,
adjust depth of plunger screw until screw touches depth guide (use
provided alternate length screws if necessary) and secure with nut.
G. Rotate button down until it snaps/locks into place.
H. Test ush by pushing button (make sure button is not
pushing screw when in resting position)

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 ow.
C. Plunger screw is not adjusted properly. Adjust screw using depth guide.
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 ushometer. 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 xture does not siphon or evacuate the bowl, 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.
D. Plunger screw is not adjusted properly. Adjust screw using depth guide.
3. Flushometer closes off immediately.
A. Urinal piston parts installed in a Closet ushometer. 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 Efciency assembly inside a higher consumption xture. Determine the ush volume required by the xture and replace with proper gpf/
Lpf piston. Use valve label and markings on xture 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 and wash under clean running water. Do not attempt to remove
lter screen. Replace piston if cleaning does not correct the problem.
B. Supply line water pressure has dropped and is not sufcient to close the valve. Close shut off sleeve until pressure is restored.
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 ushometer. Determine the ush volume required by the
xture and replace piston. Use valve label and markings on xture for reference.
6. Chattering noise is heard during flush.
A. Reduce ow pressure by turning shut off sleeve clockwise.
7. Valve leaks through Aspirator when Activated
A. Debris between the umbrella valve and the retainer. Blow air on the aspirator. If this does not correct the problem, remove retainer with 5 mm
Allen Key (not included) and wash it under clean running water. Replace aspirator if cleaning does not correct the problem.
B. Loose Retainer. Hand tight retainer with 5 mm Allen Key (not included). Do not overtight. Replace aspirator if this does not correct the problem.
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.
