American Standard Ultima Selectronic 624B Series User manual

BECAUSE PEOPLE HAPPEN
Thank you for buying American Standard products.
We’re so grateful you did, and you will be too. Because let’s face it, fans get
rowdy; shoppers and travelers are impatient; and schoolchildren are, well,
unpredictable. How do we know? For almost 150 years we’ve gotten to know
the high-traffic bathroom better than anyone else out there. We understand
that even the most talented plumbers have no control over what happens day
in and day out, and that our toilets, urinals, sinks and faucets need to stand up
to whatever comes their way.
That’s why we appreciate your stories and ideas; they help us innovate with
products that make your life easier.

PRIOR TO INSTALLATION
Note: Prior to installing the Selectronic®Flush Valve the following items must be
installed.
1. Urinal/Toilet
2. Drain line
3. Water supply line
IMPORTANT:
• All plumbing and electrical wiring should be installed in accordance with applicable
codes and regulations.
• The use of water hammer arrestors is strongly recommended for commercial applications.
All piping behind the walls should be properly secured and fastened.
• Water supply lines must be sized to provide an adequate volume of water for each xture.
• Flush all water lines prior to operation Dirt and debris can cause ush valve to run
continuously.
• With the exception of Stop Valve Inlet, DO NOT use pipe sealant or plumbing grease
on any valve component or coupling!
• Protect the chrome or special nish on the Flushometer. DO NOT USE toothed tools on
nished surfaces to install or service these valves. Also see “Care and Cleaning”
section of this manual.
• This product contains mechanical and/or electrical components that are subject to normal
wear. These components should be checked on a regular basis and replaced as needed to
maintain the valve’s performance.
Consult xture manufacturer for minimum pressure requirements. Most High
Efciency water closets require a minimum owing pressure of 25 psi (172 kPa).
Many building codes and the ASME A112.19.2 xture standard list Maximum
static water pressure as 80 PSI (552 kPa).

Note: Install Optional Sweat Adapter (Supplied) for
copper pipe supply line.
1. Measure the distance (A) from the nished wall to the
center of the inlet spud on the xture.
2. Cut the supply pipe 1-1/4” (A-B=C) shorter than the
measurement taken in Step 1. File any rough edges
off the end of the supply pipe.
3. Clean the end of the supply pipe. Push the threaded
Adapter until it is seated against the internal stop.
Sweat the Adapter to the pipe.

1. Insert ADJUSTABLE TAILPIECE (1) into the STOP VALVE (2). Lubricate the O-RING (3) with water if
necessary. Lightly tighten COUPLING NUT (4). Fig. 6.
Important: Do not use lubricants (other than water) or any type of thread sealing paste or tape.
2. Align the FLUSH VALVE BODY (5) directly above the VACUUM BREAKER TUBE (7) and VACUUM
BREAKER COUPLING NUT (6). Fig. 6a.
3. Pull the VACUUM BREAKER TUBE (7) up to meet the threaded FLUSH VALVE BODY (5), hand tighten the
VACUUM BREAKER COUPLING NUT (6). Align all components of the ush valve assembly. Fig. 6a.
4. Lightly tighten the COUPLING NUT (4) connection rst, then the VACUUM BREAKER COUPLING NUT (6)
and nally the SPUD COUPLING NUT (8). Once alligned correctly, use a wrench to tighten couplings to
make water tight connections. Fig. 6a.
The unit is shipped with adjustable tailpiece on the
right side. If needed, the orientation can be modied
by following the steps below.
1. Unthread the two SET SCREWS (1).
2. Use a athead screwdriver to pry CAP (2) off the
BODY SHELL (3).
3. Disconnect the battery wire coupling and solenoid
wire coupling.
4. Unthread the two SCREWS (4).
5. Lift BODY SHELL (3) off the BODY RING (5).
6. Unthread BODY RING (5).
7. Remove MANIFOLD (6).
8. Rotate BODY (7) 180 degrees and reverse the
above steps to complete the Right/Left swap.

MAINTENANCE
IMPORTANT: TO AVOID OVERFLOWING, THE STOP VALVE (3) MUST NEVER BE OPENED TO THE
POINT WHERE THE FLOW FROM THE VALVE EXCEEDS THE FLOW CAPACITY OF THE FIXTURE.
1. After installation is complete, peel off the PROTECTIVE FILM (1) from the sensor. Standing to one side,
block the sensor with your hand for 10 seconds. Remove your hand and listen for audible “click” from
within the valve.
2. Remove STOP VALVE COVER (2) from STOP VALVE (3).Turn on water supply 1/4 turn to 1/2 turn(CCW)
and test for leaks.
Note: Unit may ush for approximately 5 to 10 sec. when water is rst turned on. If ow persists,
turn water off and repeat step #1 above.
3. Actuate the FLUSH VALVE:
A) Cover sensor with hand for 10 seconds. NOTE: Stand outside of sensor detection area.
B) Remove hand from in front of the sensor; unit will ush in approximately 3 seconds.
4. Adjust STOP VALVE (3) after each ush until the stated ush volume is achieved, no splashing occurs and
the xture is properly cleansed.
5. When adjustment is complete, replace STOP VALVE COVER (2) and tighten to ensure vandal-resistance.
